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

I actually thought of having mine laser engraved, but then thought 'that won't look anywhere near original', so it's back to wonky Letraset !.

I'm seriously thinking of getting a repro board, not to replace mine, but to use as a known good system for testing this one. I've got enough CPUs and stuff to build the core of a repro ( with different display and no KBD ) and it would help with testing my chips. That daughter board is a nightmare as the main board won't work without it, so I won't know where any fault lies. Anything that gives me a stable starting point will help.

One thing I know will be 'wrong' when I get this working as it was 40 years ago, the display will be dim. My display driver circuit was dim from the day I built it, but it was good enough for me, so I never re-visited it. Today I would have no problem designing a replacement that performed better, but it won't be old-skool. Should I do it ?.

Cheers,

Buzby
