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.

PIPing amazing!
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 !
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.
First Kaypro working
Kaypro #1 lives! Power supply has had RIFA caps replaced, and rejumpered to 240V. Need to clean, lubricate, and test drives before continuing.
Kaypros in da house !
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.
