> Spot on. it HAS the 2114 ram chips. now to find replacements..
The slight delay after power-on before giving the error indication suggested a memory test to me... Of course it might not be 2114 problems, but I have replaced so many of those ICs over the years in all sorts of devices that I suspect them on sight now :-) > strange enough there are 12 positions for ram chips and two of them are > left unpopulated: pos 1 and pos 7. 2114s are normally used in pairs,, of course. They are 1K*4 RAMs, so it takes 2 to make a byte. I hope some kind person hasn't 'borrowed' a couple of RAMs from the plotter, that would be nasty. -tony
