Acorn A5000

Acorn A5000

Very dirty. And Rusty.






After cleaning with acetic acid & IPA


Disk drive flashes with a fault code: 00010059  Simulate &00010059
  • CMOS unreadable
  • PC-style IO world detected
  • ARM 3 fitted/ARM ID read and not ARM2
  • Long memory test performed
  • Self-test due to power-on

  • So some work needed around the CMOS.
UPDATE: 2018-09-23

Fixed the corroded CMOS tracks

It Lives!

Sorted the rust & painted (Needs lettering)

Almost the right grey, but shows up the disk drive :-o
