Hmmm, wonder if this might work for my TeleVideo TS-802 that won't boot from floppy. Hadn't thought about trying to boot it from a 'hard drive'. It might need to work shimmed under the Z80. What a cool idea!

My Adapter emulates the WD1002 but plugs into the 50 pin expansion header . Does not need the extra board like in the Kaypro 10.
Using only a STM32F4 MCU and a SD card .
Works with TurboROM and stock Kaypro ROM have to make a few fixes for KayPLUS ROM.
right now its running off a ST dev board going to do a full layout in the next few days .

True. But it isn't hard to add the necessary level shifters.Most of the new microcontrollers are 3.3V only (say a ESP32 or Raspberry Pi Pico)
I’ve been watching for a follow-up since I started down the Kaypro path this year. I have a Kaypro 2 with universal board that first led me to this thread. I’ve since obtained a Kaypro 10 (early rev). The Kaypro 10 has a Tandon drive with a failed head 2, so I’d like to move to something newer and not replace it with another 40 year old spinning drive. I’ve looked at the alternatives for emulating MFM, but I’d prefer to stay closer to the motherboard, with original ROM set, and eliminate the WD1002 also.My Adapter emulates the WD1002 but plugs into the 50 pin expansion header .
