[vcf-midatlantic] Looking for help at March 2 Repair Workshop

I am planning on attending the next InfoAge repair workshop on 2 March 2024 and hope to narrow the causes of video problems I'm having with a 1992 386 ISA-bus PC.  The PC motherboard is compromised from previous battery leakage but was mostly working until recently.  I have an apparently now dead original VGA card and a possibly flaky generic VGA card.  I'm hoping to test the VGA cards in a known good similar PC and known good VGA cards in my box.  Any assistance at the workshop, or other advice, would be greatly appreciated. Best regards, Brian Schmult
