This is very difficult question for me DaveYes, but which one (bearing in mind it is data bit 0)?

? I assumed it was a funny character only due to the floating GRAPHIC line which was due to the VIA? Bugs are likely though.. I haven't written 6502 assembly since 1980Nivag, I suspect you may also have a bug in your own code for displaying the hexadecimal letters A through F?
Good stuff. Now put stickers on E9 and E10... swap them... take more photos. Leave E7 and E8 swapped as per current state.ERIC configuration:
To do this i need to unsold the two icsNow put stickers on B3 and C3... swap them
OOPS Sorry... please see my revised post above..... I meant E9 and E10! (We know B3 and C3 are behaving... sorry for that mental outage)To do this i need to unsold the two ics
Always the same...ics solded on boardOOPS Sorry... please see my revised post above..... I meant E9 and E10! (We know B3 and C3 are behaving... sorry for that mental outage)
Not...solded on board tooHow about I10 and I11? Are they socketed?
OK. So the suspicion is that E9 may be an issue (although there may be contention from I10). You should socket E9 at least. Feel free to destroy the existing chip if it makes desoldering easier... i.e. snip legs and then desolder one at a time.Not...solded on board too
it is true! I had not seen that now the numbers indicate 59!What do you mean, “you always have a bad screen”. It’s working!
Although I suspect there may be a bug in Nivag’s code...
Compare what you have now with Nivag’s post back in #495.
