Currently Playing: IBM PS/2 386DX, Challenging, no VGA troubleshooting. Featuring the new FNIRSI DPOS350P Tablet Scope

Challenging troubleshooting on an IBM PS/2 Model 70 Type 2 386DX with no VGA video output. I diagnose an otherwise fully working MCA motherboard that completely lacks video, using the new FNIRSI DPOS350P tablet oscilloscope for signal tracing and analysis. Perfect for fans of vintage computers, retro IBM PS/2 systems, MCA architecture, 386DX hardware, no-video faults, advanced diagnostics, oscilloscope use, and hands-on retro computing repair projects. - Support me on patreon.com/Epictronics Buy me a coffee: https://ko-fi.com/epictronics - The IBM PS/2 Model 70 Playlist here: https://www.youtube.com/playlist?list=PLLN54H2azbhTYQn-p0cVgxUc4VqGMkLDY - DPOS350P: US:https://amzn.to/3SKrBWO CAN:https://amzn.to/4dP7EHW - 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 - Music by Karl Casey @ White Bat Audio
