Yes please, I would be just as interested in a Tesla programmer since those PROMs are considerably cheaper than any of the pin-compatible ones I can currently program.
Re: The MK14, beware feature creep
Before you know it you will be replacing those hard to get 2111 RAM ICs with a 6116, the PROMs with a common 8-bit wide EPROM, the RAM I/O device with an 8155 or 8255 (Neither has RAM, but the 6116 would make up for that). Basically, you'd end up with an MK15... a bit like mk14man's fine effort a few years ago...

..but using only conventional components.
