I am trying to build a build with a Am386DX/DXL and an old Morse 80386 M3 Motherboard I found in a box which was an old PC of my parents.
On it is a 1MB Memory Module and I bought a Trident TVGA-8900D-R graphics card.
As all of these parts are 5 years older than I am, I don't have any experience with these kind of parts and I need help and it seems, this is the right place to ask, so hi, here I am 😁
I connected an ATX power adapter with an ATX to AT adapter and I think I connected the both parts correctly (black adjacent to black). What got me wondering, on the board is a Chip, labeled as "Am386DX/DXL-33" but I don't know what that one is, as a PGA socket is on the board labeled "80386" so I thought, *that* was for the CPU. Because the board refused to boot without anything in that socket, I bought two am386dx/dxl-33 and inserted them. Here is problem 1: what is the right direction for them? Did I do it correctly?
With these CPUs inserted, there was little difference - no beeps, no video. So I looked for some documentation for the motherboard and found some jumper configuration and set monitor mode to colour and Batterytype to intern as I don't think I have an extern one.
(is it ok to post links here?)
Because I had no jumpers for the first times, I used a fork (shame on me), and while connecting the jumper for colour video (leaving external battery jumper open) it beeped 3 times ^-^ meaning base 64k memory error? Are the "modern" beep codes correct for these old boards?
After that I installed jumpers in the same configuration as with the fork, but I didn't get any response after that 🙁
Problem 2: The big capacitor next to the external battery jumper seems to be corrodated, would that stop the board from booting? How could I clean it?
The CPU(s?) gets warm, the PowerLED Pins work, the turbo switch and its LED do work too, so something IS working here 😁
There was no difference with the second CPU I have, but I don't have the possibility to test any of the parts 😒
Does anyone has some ideas for me? 😀
