Hi. I recently got my old A1000 back from my friend. This machine was given to me nearly 20 years ago. I have honestly only turned it on once, when i was given it, and i vaguely recal there being an issue of some kind. it pretty much got used as a monitor stand for about 6 years before ending up in the loft until i gave it away about 3 years ago. My friend did nothing with it either and returned it.
It's time to get the old girl working so i pulled it apart and tested the PSU first. Under 1amp load on the 5v rail, all voltages look good and stable and i got a good stable tick. connecting the board brings up the the Kickstart logo, albeit in magenta. something had gone out of spec, but is back now, and it's starting up in the correct colours and the drive is ticking fine. However, when it loads kickstart and resets, it sticks on a white screen. swapping the CIAs, didnt work, it wouldnt startup at all.
I fitted a PiStorm with a plain install, just mapping KS1.3, and again, with the CIA's in the original position, i just get a white screen. Swapping the CIA's iget further, to the 1.3 boot screen, however the floppy doesnt work.
I got it to boot Caffeine but it reports the drive as bad and the mouse doesnt work (well, at least the right button does. I dont have a keyboard to test.
I figure i have at least one faulty CIA. can I replace these with A500 CIA's or are there limitations on the versions it will take?
