CRT Terminator (S)VGA Adapter Conformance Tests

A major challenge in developing CRT Terminator is that there existed dozens and dozens of different (S)VGA adapters that cloned the original IBM VGA adapter, and the original IBM VGA was not based on a published specification or a hardware design standard.

This means that we do not have a single target to develop CRT Terminator against, but rather, need to test every display adapter one by one for compatibility.

This page presents results that were obtained by testing various display adapters with CRT Terminator. It should hopefully guide some expectations to what works and what doesn't, but note that any information provided in the following table is still not an affirmation or a guarantee of support.

That is, even if you have the same graphics adapter with the same graphics chip, there can be qualitative variances that can affect your results. The data is presented as-is.

While developing test suites for CRT Terminator and diagnosing behavior of different SVGA adapters, the following resources have proved useful:

⚠️Crystal CavesIncorrect palette. This is likely due to the adapter bug that requires PCITSR.EXE, and the game hooking system timer interrupt without chaining? (PCITSR and PALTSR do not work on Crystal Caves). 

Palette is ok on analog VGA output since it does not require snooping.

      SVGA bank switching code works really odd on this card. Trident has "old" and "new" bank switching modes. The old mode doesn't seem to function at all to switch banks, and the new mode works like the old mode (128KB banks). This behavior seems to be unexpected by tested SVGA programs (SEA, Sim City 2000), and is unlike seen on ASKA ZyMOS Poach below.

      ASKA ZyMOS POACH 51 (TVGA 8800CS)
      

Some possible board ISA contact or memory contact issues, since adapter sometimes error beeps at POST (although always boots), and Trident VESA driver does not recognize 512KB RAM, although in SVGA Mode 5Dh 640x480 256c always seems to work.

✅Sim City 2000 (TVGA VESA)Sim City 2000 requires 640x480 256c. UniVBE does not support this adapter, and neither does the Trident VESA driver that was supplied with Sim City 2000.

However the Trident 8900D driver disk does have a VESA.EXE that works with this adapter, and allows Sim City 2000 to work.
      
✅Warlords 2
      
❌Scorched Earth 800x600Adapter does support 800x600 256c, but Scorch does not find it.

Interesting that Scorch does report mode not found and gracefully exits, since most other times, Scorch tends to hang when the desired video mode is not found.
      
✅Scorched Earth 640x480
      
❌SEA Image ViewerOddly VESA only advertises 256KB support, and SEA doesn't run. Even though 640x480 256c mode does work correctly via SVGA init (Mode 5Dh).

This could be an adapter ISA/VRAM contact problem (the adapter does error beep at POST, but still boots).

      Unique failure in Jazz that doesn't happen on any other (S)VGA adapter.
        

From Tori.fi on Aug 18, 2022 for 40,00€.
        

This card seems to work better with manual sampling phase with DE-, Data-.
        

Adapter is a bit flaky to get good contact when seating to PCI slot.

The mode is broken in card BIOS: The value programmed to the Display Width field (3D4h/13h) is 128, which the card interprets to be a stride of 1024 bytes between scanlines. This not enough, and image is repeated horizontally after X=340 column, with different colors on the second copy.

VGA adapter BIOS bug: adapter outputs low 33.4 Hz refresh rate. (no sync to VGA monitor)
         [note]Manually sending outpw(0x3D4, (240<<8)|0x13); changes the stride to 1920 bytes to fix the bad video geometry. Then image shows correctly, although still with considerable noise.

      Adapter has a unique bug that attempting to set any SVGA mode number that is not actually supported will transition the adapter to a 640x200px 16 colors 80x25 text mode (8x8px font), instead of failing the mode change.

🚨 Adapter BIOS corrupts EGA palette indices 00h and 0Ch to random palette values on mode change, resulting in screen background changing colors on each mode change. This can be papered over in programming by manually restoring these palette entries after calling INT 10h.
        

🚨 Adapter BIOS has a critical flaw where calling printf() while in a graphics mode will hang the PC.

      This card is so crashy and glitchy that I begin to wonder if the video BIOS ROM would be corrupted.

I am fairly certain this was the video card model I had in my system back in 1996, and I cannot recall it being glitchy like this at all.
