Default Re: I found it! A very sorry looking MK14.

You've never mentioned having the official PROM programmer, I've never come across anyone who did - it must be one of the rarest items of original MK14 hardware around.

Ironically I do now possess both a capable programmer and a small stash of MK14 compatible PROMs, but even now I can't think of any application which I really need to commit to PROM. I think the other idea you implemented, battery backed RAM, must have made the need for custom PROMs more or less redundant. That's one mod which probably would be worth reinstating eventually.
