Wow! That is great ! So you do have a ISA slot that may have corrosion or just standard air junk and needs cleaning since the vid card did not work in it. Use a matchbook cover with ISA alc is the easiest way. You probably should go over all the socketed chips and press firm on them to make sure they are well seated. Then boot it back up to make sure.
Good job ! I am sort of thinking stupid cause I did not ask if you had a speaker attached.... that would have revealed a video issue.
Yes some 286 cpu run hot, AMD's and Intels being the worst, Harris and Seimens being the coolest running.
Yeah I think I will go over all the sockets with deoxit!
I did actually install a speaker after guessinf the correct connector and it gave a beep error so I tried a different isa slot.
I still need to try and figure out if there is a turbo switch connector and find the power led connector next on the list.
Never had much experience with a 286 before so had no idea on how hot they got.
I also have the mfm hdd and controller card which will be fun to see if I can get working. Might have a bunch of dosgames on it too, I know I've found a few old drives that do.
