What works, what doesn't, who has it and is it worth the wait?

Drobe reader and Liquid Silicon customer, Stewart Brookes has today written up his first personal impressions of his new MicroDigital Omega for drobe.co.uk. In the absence of fanfares from MicroDigital, we've felt it's best to hear from end users directly to get their views and comments.

Eureka magazine did publish a review of sorts of the Omega the ARM Club won at Wakefield 2003. However, we gather that the ARM Club's Omega wasn't a production quality machine (no fault of Eureka though), so Stewart's comments offer a public insight into exactly what Omega end users are receiving.

Stewart writes, in his own words,
"Thankfully, the Omega is finally shipping! I've had my Omega for about three weeks now, ordered through the ever-helpful and knowledgeable Liquid Silicon.

First impressions?
It's RISC OS (no surprises there), only faster, smoother, more colourful, how I've always wanted it to be. From the outset, MicroDigital have said that they were producing a 'go-faster' RiscPC, and that's precisely what they've done. Flexible and upgradeable, meeting currents needs while retaining an eye to future expansion.

But how does it perform? Was it worth the wait?
True to their word, MicroDigital have produced a remarkably compatible machine: to my delight, all my existing software has performed flawlessly. From my point of view, this is of crucial importance: in the last stages of cobbling together a PhD thesis, I simply haven't got time for hassles with software being incompatible, or a crucial module not working. Amongst those applications that I've been using most intensively are EasiWriter, RiScript, Vantage, and the invaluable bibliographical reference manager Citation. Similarly, I've encountered no difficulties when using Insignia, WordWorks, and Impression.

Just to be difficult (and take a welcome breather from thesis-cobbling!), I tried a few games, thinking these might prove too stiff a challenge. Rather impressively, Omega took these in its stride too, and coped ably with Alone in the Dark, Zool, Gods, Pacmania, TwinWorld, and Bubble Impact. For games titles that can't be coaxed to work under the StrongARM/RISC OS 4 combination, then A310Emu rides to the rescue, working well with Pipemania and Lemmings. Oh, loading from floppy! Oh, such nostalgia!

Clearly, then, software compatibility is not a problematic issue. In terms of increased speed and performance, this varies from application to application, but a general expectation of upwards of twice the speed of my RiscPC (StrongARM 233Mhz) seems fair for most 'real world' tasks. In several cases, the speed increase is much greater than that, and this is especially so for those applications which rely on hard disc access.

For instance, with Photodesk, a typical operation can be as much as five times faster than my RiscPC. Indeed, this is where the machine really comes into its own: gone are the days of frustrating three and four second delays while the next 'chunk' of the picture is loaded from Photodesk's virtual memory system. Rather, all scrolls smoothly and effortlessly on the Omega, in a 1280 x 1024 mode with 16 million colours (more than my RiscPC can manage). The desktop looks truly gorgeous on my 17" GNR TFT, and there were no problems setting up the monitor because MicroDigital have created a good range of 'generic' MDFs.

I should, perhaps, note that the machine ships with RISC OS 4.03. I've not subscribed to Select as yet, but RISCOS Ltd have announced that they are working with MicroDigital to resolve any remaining glitches. Now that machines are in the hands of users, I'd expect a speedy confirmation that all is rosy in that regard. In terms of support from MicroDigital, they have issued a steady stream of updates to improve the Omega's performance, and that bodes well for future advances. Things seem set to get better still over the coming months when 2D graphics acceleration becomes available, and the XScale makes its public debut on Omega. It's been a while arriving, but now Omega is well and truly here, and I'm glad to have such a capable and impressive machine sitting on my desk."

Stewart later told us that networking and USB is still not working however the floppy drive and sound are. It's of course hoped that these missing sub-systems are addressed as soon as humanly possible.

The aforementioned updates to the Omega design are, according to Stewart, carried out by using supplied software to reprogram the much hyped on-board FPGA chips, an exercise that takes about 20 seconds. MicroDigital are incidentally using the Simtec USB stack. A modem is supplied with the Omega but this can be optionally exchanged for a network card.

"Certainly from my perspective, I'm happy to have a working machine now, that I can use now, and to wait a few extra weeks for the finishing touches to appear", Stewart added. Having waited nearly three years for the Omega, MicroDigital's customers must be pretty eager to get their hands on machines right now and hold out for later updates to arrive to enable technologies and interfaces promised by MicroDigital.

Essentially, Stewart confirms what Liquid Silicon had been telling us, that Omegas are shipping to end users through selected dealers. Pause while we take a sigh of relief.

fylfot (+8.0) 8/8/03 7:22PM	This really is great news. I'm glad to hear that the Omega runs smoothly. Hopefully users will now be able to make an informed choice over which machine to buy now that a real choice is available.
moss (+5.9) 8/8/03 7:49PM	/me waits for benchmark comparisons with the IYONIX
ksattic (+4.0) 8/8/03 8:16PM	I'm looking forward to a speed comparison too. I can't imagine that the Omega has more processing grunt than a StrongARM RiscPC but I'm ready to be surprised. I'm hoping the Omega will have a working ethernet interface soon. I'm sure they can expect more sales when they get that going. Overall it's great news, though! -- Simon Wilson, Boulder, Colorado
mavhc (+4.4) 8/8/03 9:01PM	And of course whenever the omega benchmarks lose they can always claim an update is in the pipeline which will make it faster. In conclusion: a) hah to all the people who said it would never be released, b) The stupidest machine launch in Acorn history. Are they just building the machines by hand and don't want a flood of orders? It did cause Acorn problems with the BBC once demand fell.
simo (+1.0) 8/8/03 11:55PM	First po.. oh bugger, got beaten again! This has got to be the quietest product shipment ever - we kept hearing the BS stories and now it's true, we don't get any announcements! -- #include "sig.h"
jlavallin (+1.0) 9/8/03 3:44AM	Omega USB and networking not working yet....not much chance for a Mico is there. It would be nice to trade in a Mico motherboard for an Omega one though it would cost a few hundred.
arawnsley (+5.0) 9/8/03 9:50AM	My feeling (2 cents!) is that benchmarks for the two machines are not really the main deal. If you read the article above, the author has hit the nail on the head - software compatibility. For many users, compatability is more/as important than raw benchmarks (especially as most current RISC OS apps are optimised for RiscPCs - much like the way software is written for consoles). That's not to say that both machines don't beat the RiscPC (!!) and also that the Iyonix is a slick machine if you use 32bit apps. Just try and assess the machines on more than just CPU speed, after all, we're not running Windows on them !!!
Smiler (+8.5) 9/8/03 9:56AM	Now all we need is a side-by-side review of the Iyonix and Omega (although to be far to MicroDigital we'll have to wait for the updates). I don't mean benchmarks - they can't always tell you which is best in a real life situation. We need a grouptest in actual use - how a user thinks they compare. -- Smiler - Alex Melhuish
nunfetishist (+8.0) 9/8/03 10:42AM	*In reply to arawnsley:* If compatibility is paramount, and performance is less important, why not just stick to RiscPCs? Also remember, that the CPU in the Omega is pretty much the same as a StrongARM RiscPC - it's everything else that yeilds the speed increase.
moss (+6.9) 9/8/03 10:57AM	For my purposes, I have no compatibility worries; I would be perfectly happy only using the software that works properly with the IYONIX - software that is still being developed. Other people may have different needs; but I would have thought Aemulor would take care of a lot of them.
nunfetishist (+4.0) 9/8/03 12:16PM	Is (Iyonix + Aemulor) more expensive than a single Omega? If I were still a mainly RISC OS person, I'd still be quite content with my RiscPC, as I assume many are. Software houses must be careful to take account of their needs and wants too - not everybody wants to, or can afford, to own one of these new spangled machines. So software authors: Don't go around making exclusive use of all the fun toys in newer RISC OSes - you'll penalise the majority.
AMS (+3.0) 9/8/03 12:29PM	If the above represents wide availability of Omega, great (and congrats to all involved) ! As to Omega's famed compatibility do bear in mind it is the case with the machine as shipped - whether it will be still as compatible when the xScale/ArmTwister upgrade is fitted may be an issue to be revisited. The xScale is a 32bit only processor how this will co-exist with a 26bit only RISC OS is going to prove interesting. nutfetishist makes a very relevant point (unanswered) that if compatibility is all that matters (and not speed) why not stick with a RiscPC ? Roll on the benchmarks (RPC Kinetic 300, Omega and Iyonix) and also comparisons then and let's see what the overall concensus is.... -- Annraoi McShane,
Spriteman (+4.0) 9/8/03 1:44PM	I'm very pleasantly surprised by the compatibility of the Omega. Remember, it doesn't have any of the custom chips that the RiscPC has (VidC, etc). Critisism has been leveled at MD over their ability to effectively program the FPGAs on the machine. Well, to my mind, this proves they /do/ know what they are doing. Taking a long time in doing it, perhaps. Now, what they must do is come good on the promises of whizzy bits for the Omega. I'd lay money on them getting networking going very soon. But what about 2D acceleration, mpeg decoding, 3D stuff and the ArmTwister? -- Spriteman.
mavhc (+1.5) 9/8/03 2:00PM	The point is compatibility is more important than speed to some, therefore a machine that's compatible and faster is better for them than a machine that's not so compatible and fastest. Does Sibelius work on Omega?
hzn (+4.0) 9/8/03 2:14PM	Good to read that finally Omegas get to the users. I remember the presentation at RISC OS Expo in June 2002 (yes, well over a year ago) where it was said that they're ready for production and just neet to get all parts together... Must have mis-understood that since I assumed "parts" didn't include the odd hardware driver i.e. the software. Anyhow, I'm glad it is there so that now those eager to upgrade can do so. Opposed to a RiscPC I guess for things like Photodesk the speed increase comes from the availability of lots of RAM mainly (no need to chache parts of the image on disc). Well, now comparisons are what we all want to see I guess. And please don't wait too long with them stating that MicroDigital or Castle are still enhancing their Omega or IYONIX pc. With that statement you'd have to wait for ages with a side-by-side review because both are making their system better all the time. Bascially I have the impression that Omega is better for those who want some more power with no hassles (fast harddisc, more RAM, a bit faster StrongARM). IYONIX pc with a twice as fast processor will be faster even, but you need 32 bit software and/or Aeumlor for 26 bit thus there is the odd compatibiliy issue. I do hope for fair reviews on the net comparing the two so that all of you out there wanting to upgrade can decide which system to go for... it's too late for me due to my account not allowing for an Omega in addition to my IYONIX pc but I'm happy with it and hope the up-coming reviews don't make me feel I picked the wrong one... BTW as for compatibility issues, there is one which will affect Omega like it did IYONIX pc: The odd application wasn't working as it should with 512 MB RAM in the computer since the programmers never expected that high size values. But those things have been sorted out by now, ARAIK. Herbert
mavhc 9/8/03 2:35PM	Castle should be quicker at solving problems like that as they are writing their own OS whereas MD will have to ask ROL to fix things. Of course if you want Select you've only got 1 choice ATM. Now the generation 4 machines are available, what's in store for generation 5? Castle would seem to have the lead here, although they're relying on a chip with in built everything. If a similar faster chip appears they're fine.
ribbit (+1.0) 9/8/03 10:23PM	Nice to see it; but is competition good for the RISC OS market at this stage? As a newcomer to the scene (or recent returnee, depending on your perspective), I'm all at sea as to which one I should potentially spend money on.
Snig (+0.5) 9/8/03 11:16PM	Newcomers to the RISC OS scene in my opinion are most likley to be computer literate. I don't think that there would be much issue in Joe Bloggs with a European Computer Driving License or similar expertise to differenciate between the two. This mostly should be done by advertising and promotion anyway...
andypoole (-1.6) 10/8/03 10:58AM	Surely it doesn't matter if newcomers are computer literate or iliterate - RISC OS is easy to pick up (specially with the welcome tape and welcome guide to hand :p
moss (+2.4) 10/8/03 1:42PM	Well, we need to give newcomers all the help we can get, of course. And to decide which computer they should buy, we need a side-by-side comparison of the IYONIX and the Omega. It's a great shame Microdigital isn't helping with this; it's almost as though they're ashamed of what they've produced. No doubt a comparison will happen at some point, however; as more machines get delivered, you can't hide it forever
diomus (+2.5) 10/8/03 2:05PM	The problem is that ultimately, people will be looking for a comparative review of the Iyonix and Omega that will in the end recommend a machine to them. And even after that, Omega supporters will say that the Omega is in continuous development and the Iyonix has had a head start etc etc., thus playing down the review. End users will ask, "What do I want? Iyonix or Omega?" Whoever writes the review needs to have the balls to stand up and say "If you're a graphics user, you'll want ... If you're a games player, you'll want ..." and so on. And also be prepared to address any criticisms of bias. I know that if/when we do a comparative review, we'll not treat the article lightly. Chris, drobe.co.uk
mavhc (+1.4) 10/8/03 3:07PM	First stage is getting accurate information about what's available today, neither website tells the whole story, maybe a Current Spec page for both computers is needed, explaining what doesn't work, what's mostly working, what's been fixed, and when. For the iyonix a what software doesn't work and what software doesn't work with aemulor section would be useful. Then you could go over the top and get people voting on what needs completing before they'll buy the system so the creators can concentrate on the important parts.
AMS (+4.0) 10/8/03 3:11PM	It's going to be awkward to do a comparative review alright (I don't envy you). The notion that "omega is in continuous development" may well be true, though the less circumspect might uncharitably say "never finished". A review has to be done as a "snapshot" at a given moment in time - what is true then is all that can be used in the review. If (later) new features are added to either machine then that can be used as a follow-up to the review at a later date - if people are expected to buy a given machine now then the review can only realistically be made above features that are available now (otherwise such a review would be misleading). Hopefully MD will see fit to provide a machine for review with all the latest FPGA updates in place so that a fair comparison can be made. Can't wait to see that review ! -- Annraoi McShane,
diomus (+5.5) 10/8/03 3:17PM	Castle and Aemulor publish lists of compatible software so you just need to rifle through those to find what software is known to be compatible. To show how compatible the Omega is with the RiscPC, remember that it booted RISC OS 4.33 (only aware of RiscPC-esque architecture) with only a few glitches. Chris, drobe.co.uk.
thegman (+1.6) 10/8/03 6:28PM	I think as long as the review simply states the facts about what was included in the box, and what is forthcoming, we can all use our imagination as to which is the better machine for us as individuals. It great that it's available, and also great that Stewart likes his new machine, but I'm still a bit concerned like moss about why MD is not singing and dancing about it. I'd be interested to hear what Stewart has been told about FPGA updates and XScale etc. I can understand the MD would not want to be drawn on such things, but Stewart as a paying customer has a right to some answers.
diomus (+1.6) 10/8/03 6:50PM	MD won't speak to the press, they don't do publicity. fylfot (Ian C) phoned MicroDigital recently and that's their official line. You can phone them too, all of you preferably, and find out what's going on. It's not a situation we're entirely happy with but that won't stop us covering the machine. As long as it runs RISC OS, it's something we'll cover. Chris, drobe.co.uk
Revin Kevin (+1.6) 10/8/03 7:50PM	There is a review on the Omega in the latest Risc World Cd mag. IT stated that every programe that worked witht the StrongARM RiscPC worked with the Omega but only faster. And in the case of Photodesk a lot faster as the Omegas faster disc interface.
moss (+1.5) 10/8/03 8:03PM	I think everyone knew that the Omega would be faster than a StrongARM RPC. It's the comparison with an IYONIX that we all really want to know about. A pity RISC World didn't do that
stdevel (+3.1) 10/8/03 9:14PM	Benchmarks between machines might be interesting, as Omega has the potential for codesign (ie the FPGA's could be used for hardware acceleration of inefficient algorithms). As a "general purpose" machine, perhaps the Omega has a way to go, but for some specific applications it could be a scorcher. Imagine having hardware accelerated database searching, pattern matching, encryption, parallel decryption etc. Not the sort of thing a general desktop user might need, granted....
knutson (+0.1) 10/8/03 9:19PM	Not only is the disk I/O faster than the RiscPC but so is the memory bus. This would also have a positive impact on applications like Photodesk. Thanks Stewart for giving us your thoughts. Cheers Steve
