Gotek Disk Images

Here are the disk images I use for some of my vintage computers.

These are intended for use with the excellent HxC2001 firmware. The HFE format should work with the standard Gotek firmwre but I have not tried that personally.

Microbee – double sided 40 track

Kaypro IV – double sided 40 track

Kaypro II – single sided 40 track. Note that the Gotek will need to be configured to ignore the side select signal.

RIFA adventures

I need some 4700pf/300v RIFA caps for Kaypro power supplies, so I ordered replacements from element14.

However, I’m not sure these parts are suitable as they are somewhat smaller than I was expecting. What’s the consensus of the hive mind – can I use them?

UPDATE: consensus was that they are OK to use, provided they fit physically!

Disk drive working

Kaypro #1 wouldn’t boot from a Gotek, but Kaypro #2 is up and running!

Update: the problem with Kaypro #1 was the WD9216 data separator. Swapped this chip with one from another system and disk reads started working.
