For those who want to make their own cable, here is the pinout of the connector
UPDATED: the previous diagram was wrong- this is definitely correct!

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.
I recently purchased a large cache of Microbee computers with the intent of refurbishing them and reselling to the retro computer community.
My original intent was to work my way through them, repair them as needed, and sell them onto the vintage community at cost.
I’ve done this for five or six systems, but I no longer have the time to invest in returning the remainder of the systems to fully working conditions.
I’m now offering seven Microbees in as is condition. All are tested and working. DRAM has passed a memory test, video is stable, and at least some of the keys on the keyboard are working
All Microbees have been sold. I’ll post again if I have more for sale.
The follow caveats apply:
I’m working through the cache of Kaypros. I have a II and a 4 working with Goteks, but this is the first with only floppies.
I celebrated by making a logo for the disk label!
If you want to know what 40 year old RIFA cap looks like, I got you covered. This specimen is from a Kaypro 2 switched mode power supply.
First time in 35 years I’ve used CP/M “pip” to copy a file. Nailed it first time! First refurbished Kaypro floppy drive is working !
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!
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.
Kaypro #1 lives! Power supply has had RIFA caps replaced, and rejumpered to 240V. Need to clean, lubricate, and test drives before continuing.
I’ve started unpacking the shipment from the US.
2 x Kaypro II, 1 x Kaypro2 , 2 x Kaypro 4, 1 x Kaypro16, and more boxes yet to be opened.
