Mystery Box: Testing, fixing and overclocking motherboards

Time to look through a mystery box of PC parts I was given! What will I find? I also make the first use of a video microscope on my channel, overclock an old IBM motherboard and more! I have a follow-up overclocking video which will come out on the second channel to see how far I can push the overclocking on the old Type-1 motherboard. 0:00 Intro 2:52 386 SX-40 motherboard 8:40 486-DX50 motherboard 22:09 Firefly Serial to Bluetooth Adapter 25:17 286-12 Motherboard 37:03 Testing and overclocking a IBM 5170 motherboard 57:50 Outro Motherboard info: AMD 386 SX-40 MX Chipset MX83C305FC / MX83C306FC TB Taiwan 486-DX50 MB-1420/25/33PB/PV PCB Rev A Chips and Technology / Bioteq P82C206 / 92C4800 286 Motherboard Baby 286 Mainboard VIP M214002A BAM12/A0 BAM16/A0 Made in Taiwan --- Video Links The microscope Andonstar sent me: Andonstar AD409 HDMI Digital Microscope https://amzn.to/3iZZ7WX The one my friend bought and he says works really well too: Andonstar AD208 Coin Microscope https://amzn.to/3kRihAF IBM 5170 patched BIOS and write up: https://archive.org/details/ibm-5170-...
