IME the ROM chips are fairly reliable and are unlikely to be the issue. If you've already recapped the board I would then focus on the RAM chips. Did you check to ensure the capacitor electrolytic didn't damage the logic board?
My technic is to use my Hakko desoldering gun to remove the bulk of the solder and then use hot air. When using the hot air I move it back and forth over all of the pins while lightly pushing down on the end pin where I currently have the hot air pointing. At some point the pin will push down...
I have a logic board that I am going to practice removing 30 pin SIMM sockets as I think this would be a useful skill to have. I plan to use a Hakko to remove the bulk of the solder and then use hot air to remove the socket. This has worked well for removing 40 pin DIP chips so I don't see why...
@wrljet I think I am going to find a board with a broken SIMM socket and give my hand at trying to replace them. I have a Hakko desolder tool as well as hot air. Typically for things with a lot of pins I use the Hakko to remove the bulk of the solder and then use hot air to remove the actual...
Since mine has an 80386-40 version I assume mine is a later version (though the board does support 25 and 33 MHz Intel versions). It's currently configured with 20MB and the specs say it supports 32MB. I think higher memory capacities are likely supported on "workstation" class desktops and...
Always got to be a few who take a post and pick it apart. It's not like it wouldn't be common sense to assume that any one person, or even every participant in this forum, would know of every single 80386 motherboard. That said I clarified the intent of the post so let's move on and operate...
Just curious if anyone knows the maximum memory that was ever supported by an 80386 motherboard. I'm not asking about how much memory the 80386 could support but rather how much memory was ever actually supported. I have an 80386 system that supports a maximum of 32MB. Anyone know of a...
As with anything the answer is: It depends. What would be your interest in obtaining an 80386 based system today? A specific piece of older software which runs optimally on it? Nostalgia? Something else?
I just purchased an 80386 DX system about a month ago (I purchase an 80386 SX system about...
Advent of Computing has a nice video on the 4004 and 8008:
Episode 16 - 4004: The First Microprocessor
Episode 21 - 8008: Intel's Second Shot
I can't speak to the accuracy of what's presented (would be interested in hearing what other people think) but I thought it interesting.
