Currently Playing: Rare 486 interposer repair & IBM PS/2 Model 57SLC restoration (8557 & SLC2)

This video features a rare 486 interposer repair and an IBM PS/2 Model 57SLC (8557) restoration. I repair the 386-to-486 interposer and bring the PS/2 system back to working condition. I also compare performance using classic benchmarks. Perfect for vintage computer enthusiasts, retro IBM PS/2 collectors, MCA systems fans, 386 and 486 upgrades, rare PC hardware repair, old-school benchmarking, and hands-on retro computing projects. - Support me on patreon.com/Epictronics Buy me a coffee: https://ko-fi.com/epictronics - Tools I regularly use FNIRSI DWS-200 Solder station PinePower Bench PSU AMTECH NC-559-ASM Flux Kester 951 Flux pen Hanstar 861DW Rework Station Pro'sKit SS-331 Desoldering Station SEQURE HT140 Desoldering Tweezers Multicore 60/40. 0.38mm solder AOYUE int883 PCB Preheater RIGOL DHO800 70MHz four-channel digital Oscilloscope Tektronix 2246A 100 MHz four-channel analog Oscilloscope FNIRSI DPOX180H 180MHz Handheld Oscilloscope UNI-T UT61E Auto Ranging Multimeter UNI-T UT890D Manual Ranging Multimeter FNIRSI LC1020E LCR/ESR meter TL866 II Plus Programmer InfiRay P2 Pro Thermal Camera TOMLOV TM4K-AF Flex Microscope Dremel 3000 with flexible shaft MaAnt Mini"Dremel" DeoxIT D5 Contact Cleaner PCBs from PCBWay.com - Support me on patreon.com/Epictronics Buy me a coffee: https://ko-fi.com/epictronics Join me on Twitter: https://twitter.com/epictronics1 - Music by Karl Casey @ White Bat Audio
