TRIDENT TVGA8900 ISA DRIVER



I'm pretty sure of course, could be wrong if you slightly modify your XT to start fake memory refresh cycles, it stops working with your VGA adapter. Too bad it's not very straightforward to conduct this experiment - will require some trace cutting and soldering Vic3Dexe November 8th, So it is likely that the differences in behavior are the result of the wait logic implementation Well I don't think so, because the problem is not in wait states themselves. Very interesting how would BALE Trident TVGA8900 ISA like.

And, surprisingly, I didn't notice any differences in ALE behavior between these two boards. Below are signal captures from both boards: According to the documentation, the pulses ALE every the processor transitions from T4 state to T1 state. So, no major differences between PC and XT here Stone November 8th, I've observed the same results here, as well. Actually, there is a huge difference in your pictures regarding to ALE signal Just imagine that a card uses ALE signal to latch the address. If you look at the picture Trident TVGA8900 ISA your XT, everything looks right - ALE starts just before the address bus gets the address, and goes down when the address is fully established on the bus.

But look at the PC picture now! Yes, it works in the same way with Trident TVGA8900 ISA addressbut B which is immediately after the refresh cycle is completely different story.

If the card uses ALE to latch the address, instead of latching B it will latch 4C59 - the address of the memory being refreshed Possibly in later XT models they added something to fix this issue Do you think my explanation has a sense? Tronix November 8th, I think internal Trident's logic monitoring ALE falling edge and latch Trident TVGA8900 ISA into internal latches. But it never happens.

This line is provided by the Bus Controller and is used on the system board to latch valid addresses from the Trident TVGA8900 ISA. Microprocessor addresses are latched with the falling edge of ALE. Note the "when used with AEN" comment. I am not quite sure what it means, but this signal is open on my SVGA board, and on other Trident TVGA8900 ISA based cards that I've checked Neither card worked on a motherboard running the Anonymous Bios. The resulting combo-chip saved precious board-space by eliminating several RAM chips normally required for framebuffer storage as well as providing other advantages, offset by a higher manufacturing cost-per-bit.

In this market it competed with NeoMagic. Although Trident enjoyed some success with its 3DImage and Blade3D product-lines, the entry of Intel into PC graphics signalled the end of the bottom-end, graphics-chip market. Trident partnered with motherboard chipset suppliers several times to integrate its graphics technology into a Trident TVGA8900 ISA chipset i. So the question is, why in gods name are you trying to get that thing up and running?

We are talking 90's, even early 80's. Much of my time in tech school was spent designing circuits to interface with this bus.

It was still used on servers and industrial or workstation PC's in the last 10 years, but has since been completely phased out Trident TVGA8900 ISA existence. If you have any PCI slots on your motherboard they're usually beige in color and about 4 inches long with a keyed slot at the frontthen get yourself a cheap PCI graphics card and you're done.

ISA cards are rare and are either expensive or may have compatibility issues. I used it to interface with a 4 channel radio control for a RC plane.

I wrote the software in Pascal with embedded assembly to control each of the channels via the keyboard. It worked well though I never ended up flying the plane with it.

All the front end was done in graphics which wasn't an easy task for an executable that ran in DOS. Wow, even older than AGP.
