Acorn A440/1 Archimedes Repair Part 2 (Sound, Hard Drive, Floppy Drive, Risc OS Upgrade & More)
The second part of my Acorn A440/1 restore. I talk more about some of the chips and things in part 3.
There’s a small mistake there when I talk about the FDD – you can replace it with some PC FFDs, but a small mod would be required and some drives might not work. Also another small mistake related to the max CF size – it’s 32GB I think.
ZIDEFS Podule (IDE Interface – up to 32GB CF Cards)
Risc OS 3.11 ROM upgrade (4 X 512KB) – Older machines require a ROM carrier board to fit these.
