I've got two RiscPCs, one sadly with battery corrosion, but the other doesn't but its keyboard no longer works - it worked fine a year ago and we used it for games before replacing it with a Pi400. I thought I'd like a rummage through my IDE and SCSI drives.
I removed the batteries years ago, so no CMOS settings. It boots to supervisor and has a flashing cursor (though there's no beep which may or may not be related). It has the wrong monitor type, but it's quite easy to read the blurry text (StrongARM/Supervisor), and see the cursor. Holding down the various keys on reset does nothing.
As it turns on, the Acorn keyboard lights all flash (though I wouldn't be surprised if that's the keyboard itself doing that). The keyboard lights then turn off and nothing works - no key press does anything, not even caps/num/scroll lock. I've tried three different Acorn keyboards all with the same result.
On the second (corroded) RiscPC, the three keyboards all get further, with caps/num/scroll lock all toggling when pressed. But it has no display.
Any ideas on how to get at least one booting? I've got little more than a multimeter and cheap soldering iron, so the corroded one is way beyond my soldering skills - I can see some chip pins have no tracks to attach to. But that it gets further with the keyboards at least shows the keyboards work.
Thanks for any suggestions.

Re: Risc PC keyboard
If the lights toggle then RISC OS is running in some capacity.
I assume that you've held down Delete while powering on?

Re: Risc PC keyboard
If you can get yourself a PC keyboard with PS2 connector (or even a USB one with USB to PS2 adapter), this will work as well.

Re: Risc PC keyboard
If getting the Risc PC running proves too tricky, you have another couple of options if you have a USB-IDE adaptor:
1: Plug the drive into a Pi running RISC OS 5. It should mount the drive and you can copy the contents elsewhere.
2: Plug the drive into anything running Linux and use dd to make a disk image file. RPCEmu can mount this as a virtual drive.
Not sure how well this will work for SCSI drives, mind you...

But note RPCEmu can't read disc images when using RO5. Plus of course if your disc used long filenames, you'll need to use RO4+
