I've used a UNI-Pod and still do. As long as the latest software was installed, it fixed all the filer issues the early stuff had and it's still going strong. It was a few years ago but I did some experimenting and did get the internal 8 bit expansion working with an Econet module, sound sampler and SCSI interface. It was a hack to get the software working but all it took was to change the address offset from the default Econet address to point to the card and a patch to the drivers to fiddle with the IRQ mapping. The podule seems to have multiple IRQ sources and there were registers to enable the expansion FIQ/IRQ to the podule bus. Although it had an FIQ pin, it appeared as just another IRQ. I chose the podule base offset address according to slot number and the podule access cycle needed for the devices on the "econet" modules.
For the sampler and econet, I worked out which pins were connected from the module to the the 15 way back panel connector and wired up a plug to suit. Worked quite nicely. I assume that this is the "parallel port" mentioned in previous comments?
I found my old notes the other day - original hard drive long gone - and the more technically inspired users might find this of interest:
Expansion socket base offset &3A00
A0 of the slot was connected to LA2 of the bus and so on.
status was the masked IRQ = raw AND mask
I worked out that the expansion "FIQ" mask bit was bit 7 and the IRQ mask bit was on bit 1. Bit 0 appeared to be the global podule IRQ. Whenever I played with bit 0 of the IRQmask, bad things happened The other bits appeared to be for the IDE, network and USB. It goes without saying that a read/modify/write was needed with IRQs off to change any of the mask bits.
Back on topic, I for one am looking forward to seeing exactly what's on the new V-POD. If naming is anything like the UNI-Pod (usb, network, ide) then I vote that V is for Video
South East 2008 theatre talk videos now online Didn't make to the South East 2008 show in Guildford this year? Not to worry, because on top of the usual Drobe coverage, you can now watch videos of the presentations made by RISC OS Open and RISC OS Ltd staff at the event. Recorded live at the show, the videos, in which products and projects are talked up by developers to punters, also include question and answer sessions from the floor. 13 comments, latest by rjek on 9/12/08 12:02PM.
