I noticed that the uploaded Hercules BIOS version is G4H, while in the screenshot is G5H. Is it possible to upload the G5H version? Thanks in advance.

I assume 36 Mhz clock is needed for the classic Super VGA (800x600 16c). http://tinyvga.com/vga-timing With merely 256 KB of video ram, two SVGA resolutions are possible: - 640x400 @256 (VBE mode 100h) - 800x600 @16c (VBE mode 102h, 6Ah) The VBE BIOS isn't in ROM, however. It was a DOS TSR stored …

I happen to own this card: http://hw.fagear.ru/paradise-pvga1a-jk/ Mine comes with a pin header on JP1. If jumpered, it connects the output pin (lower left as seen on the front of the card) of the 36MHz oscillator to a pin on RP2 (resistor network). Does this enable the oscillator output? (the …

Can the LM386N-3 be substituted for the LM386N-1? It looks like the LM386N-3 has higher output power (500 mW vs 250 mW). I'm worried that the higher output power might have increased noise/distortion or not be appropriate for line-level output? Also, the SN74LS245N for the Adlib clone is completely …

You could try the PAL for GVT-2 for a start: https://www.vogons.org/viewtopic.php?f=46&t=80220&p=948533 Unfortunately it does not work. No POST beeps, no display signal. My PC Analyzer Diagnostic Card shows the FF AMI BIOS code - that means probably that the motherboard is trying to boot. This …

I recently came across the same mobo, but the GAL chip at socket U2 is missing. If possible, can anyone provide the file (usually .jed) for flashing a new GAL (and hence possibly reviving the motherboard)? Thank you in advance.
