Far Eastern RISC OS 4 ROM source found

By Chris Williams. Published: 5th May 2004, 12:44:56 | Permalink | Printable

Everything's going to be OKI

RISCOS Ltd.The future of RISC OS 4 on ROM is secure says developer RISCOS Ltd., now that a supplier of suitable OTP (one time programmable) ROMs has been found. The chips, manufactured by OKI but discontinued two years ago, were originally used to produce RISC OS 4.02 releases, and can be used now to produce batches of RISC OS 4.39 (aka Adjust).

The first batch of 150 copies of Adjust were sent to customers on Flash ROMs, which can be reprogrammed at a later date, unlike OTP ROMs - RISCOS Ltd. has pledged that Flash ROM Adjust users will be entitled to "a free Flash upgrade to the next version of RISC OS Adjust within 6 months of purchase".

"A chance conversation at a recent Trade Fair led to the discovery of a large unused batch of ROMs held by a Far East manufacturer," explained RISCOS Ltd.'s managing director, Paul Middleton. "A sample ROM has been received and it is expected that the full supply of ROMs will be received in the UK and cleared through customs by the end of May."

And for the silicon squeamish, like this editor, there's always the softloading Select scheme if the idea of re-fitting ROMs brings back bad memories of hacking that old A5000 to bits.

Are the Flash roms that the used the same ones that had RO4.02 on? I thought they caused timing issues, or have they changed the design or something?

Why didn't ROL just use Flash ROMs anyway? If they'd of done this for Select, then it would save with the trouble of softloading the OS over the ROMs after booting - much more convinenet and faster. When an update is released, the ROM is flashed with the new version - simple! I'm sure users would rather pay the extra it may cost for Flash ROMs with this kind of convenience.

They did - with 4.01 (or 4.02, I forget). There were reports of timing problems, and then everything reverted back to normal roms and softloads. Select is 6MB nowadays, so it wouldn't go onto rom so easily (they trimmed it for Adjust, apparently)

And a RiscPC can't reflash Flash ROMs, so you'd need to remove them anyway.

Can't see that it would be hard to make Select 4MBs, after all it's not as if it runs without a harddrive, just put anything big on disc, sprites, apps, modules, whatever you want.

Also I believe that the flash roms still need to be taken out of a RPC for re programming as the PRC doesn't have the necessary circuitry for programming in situ.

All IIRC of course!

Reply to adamr: Sorry off topic but where can one find out how this comment stuff works, what codes to use, how to get smileys, etc. It's embarasssing when tags appear!

john: The Adjust Flash ROM issue was answered on the Select list by ROL: "The Flash ROMs have the same electrical characteristics as the original flash ROMs. The ROM timings have however been slowed to widen the likely timimg tolerances on early motherboards." They've slowed the ROM access speeds slightly to correct for any problems, it seems.

pipalya: See [link] or the site forum, in the forum section for other questions.

Chris. Just me.

Are these Flash ROMs compatible with the Iyonix for when ROL makes Select.Adjust 32-bit?

sp: troll :p Iyonix has no ROM sockets. Its flash is on the motherboard and s/w updateable.

Chris: Yes, but that doesn't explain why the preview shows something different to what is actually posted :-( If the preview worked, you wouldn't need to RTM ;-)

Spriteman:

This is a pointless question. Allowing something Select-like to run on the Iyonix is not a question of making it 32-bit. The really difficult part is to add all the support code for the Iyonix hardware. So, it is simply impossible for ROL to produce an operating system that you can plug into an Iyonix. This will never ever happen.

ROL may of course provide Select features for Iyonix users. This is an entirely different matter. However, you would either simply install them on your hard disc, or, assuming that ROL and Castle work together, they may be integrated into a later version of RO5, in which case you would flash them into your Iyonix Flash ROMs using the standard RO5 update procedure just like the upgrade from 5.03 to 5.05.

wuer: you can be sure that Spriteman was well aware of all these issues. I've asked him to return his green wig ;-)

While we consider the possibility of ROL and Castle working together as remote as the discovery of WMDs in Iraq, we already have plans for more versions of Windows.

5000 copies of ROS4 sold now as RPC/A7000 upgrades.

Wouldn't a free upgrade be worth more than a 10ukp discount?

A flash ROM for a Mico is pointless as it already has one - this is not reflected in ROL's pricing structure for Adjust. To my mind it should be the same as the difference between VRiscPC and VRiscpc Adjust.
