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.
