Re: I found it! A very sorry looking MK14.
Hello all,
Sorry, not had a chance today to even power it up.
Yes, the chip is a 7442. Not sure if that was original from SoC, or if I put it there. Some of the other chips are definatley not SoC, 'cos they've got RS part numbers !.
When the chips were in Micky there was my off-board display, with transistors and FND500's I think, so maybe the on-board chips were not so important then.
Regarding the display, is it the correct one, and have I wired it correctly ?.
The PCBs, both original and replica, have two empty holes at the left end of the display connector. ( I used these forty years ago to supply power to my off-board display. )
At least with this PCB I'm not debugging the wiring, just the chips.
Hopefully I'll get some time tomorrow.
Cheers,
Buzby
