Hi all,
I've obtained this IBM PC which had the top cover of the 5150 but the power supply on the back says 5160. When I opened it, it seems to be a 5170 actually as it has a 286 CPU !! Imagine my surprise. Now it powers on but all I get is double beeps. It had a MGP (?) graphics card (I CGA or MGA I think) so I removed that as when I connected my CGA to it, it did not want to display anything. Anyway, so I put in a 16 bit ISA VGA card. Same result, double beeps and no display.
I took a picture of the corner of the board. Does it look like I am missing memory (due to empty slots) or are the chips just below that memory?
The reason I am asking is because the memory is missing then it explains why the PC is not starting, but also because the chips below the empty slots do look like memory chips (they have the -80 at the end indicating 80ns chips).
Regards,
Vlad.
