386DX-40 Upgrade! Texas Instruments 486DLC-40 and a Rare Cyrix 486DRX2-66!
Today I look into upgrading my 386DX-40 to a 486! As usual it doesn't go off without a hitch or two and I even need a soldering iron to make it happen. The joys of retro computing! Motherboard is an M-326. Unknown brand. I have discovered the camera setting that was giving me terrible video quality so I will have clearer videos going forward.
