Re: Atomwide A5000 8MB

I think that the 8Mb RAM card in one of my A5000s is a fully populated version of the Atomwide card shown in the picture at the beginning of this thread. I’ll need to dig out the machine from under the rubble of electronics clobber on my desk and take a picture. It would be marvellous to clone this ...

Re: Archimedes Level 4 File Server

Here, at last, is a scan, admittedly not a very good scan, but a scan nonetheless, of the Acorn RISC OS Level 4 Fileserver Network Manager's Guide - Issue 1 - 1990. This scan was not easy to get done. Still, for all its faults, it's better than nothing. The PNG files (in case someone wishes to have ...

Re: RPC with faulty keyboard interface

The ROM apps were removed from RO 3.5 but returned to their rightful place from RO 3.6 onwards. I’d suggest upgrading to RO 3.7 or 3.71 anyhow, in due course. In terms of which ROM modules you’ve got loaded on RO 3.5, you can check the output from *ROMMODULES against the list given on this handy web...

Re: RPC with faulty keyboard interface

Great progress drumm3r!

Now, regarding your missing ROM apps - are you running RISC OS 3.5 by any chance?

Also, one pitfall to be aware of is that it’s possible to run into trouble with the HD after a CMOS reset on a RiscPC with RO 3.5/3.6 - make sure you do a *configure ADFSBuffers 0

Re: RPC with faulty keyboard interface

From your descriptions, I think your RiscPC is getting through the POST sequence without error. Ending up at the supervisor prompt with an incomplete set of ROM modules loaded can certainly be a symptom of a failing CMOS chip.

@tomc - I’ve recently made a 2nd floppy cable for an A4000, and it works nicely, the cable exits via the rear mini-podule case slot, connecting to a Gotek drive sitting on top of the case. I’ve sent you a PM with some details.
