I’ve been extending Dave McMurtrie’s implementation of IEC disk support for the KIM-1 (from the ca65 port of Nils Andres, aka netzherpes). I’ve added long file names, sending arbitrary commands to ...

In a recent mail exchange with Dave Plummer, Hans Otten and Rutger van Bergen, I learned that Hal Chamberlin, designer of the K-1008 “Visable” Memory Card and other MTU products, wrote an assembly ...

There are two bodge wires in the board. They don’t seem to be a repair, but a factory modification and they match the schematic. It would be very easy to route proper tracks instead, but then it wo...

Board outline completed and all components in place. Starting track routing now.

I’m working on an as accurate as possible replica of the MTU K-1013 Floppy Disk Controller for the KIM-1. This card used the ubiquitous NEC uPD765 IC and supported 5.25 and 8 inch, double side, dua...

I’ve designed a functionally equivalent recreation of the latest version of Corsham’s SD Card Shield. Sadly, Bob Applegate, the man and soul behind Corsham Technologies, passed away this summer and...

Finally, only the audio and power connectors are on the PCB. I’ve opted for interchangeable daughterboards for giving the RS-232 or USB connectivity, together with the IEC and Corsham’s SD Shield c...

Update: Project ditched in favour of this one I’m working on an expansion and IO board for the application connector of the KIM-1, which I’m shamelessly calling “KIM-1 Super I/O” :stuck_out_tongu...

OK, after some thinking (not much, this is a hobby anyway ) and some discussions in the Forum64, I’m ditching the original idea for the application and IO board and go...

I’ve reproduced the manual that came with the K-1008 Graphics Software Package, typed in the assembly sources and listings of the programs, made 64tass versions of those sources and built binaries ...
