Do any video cards use 44 pin 1mb sram?

Found this random vpn card. Not much info online. Does it have practical uses now, or value to someone worthy of posting it on ebay? The ram looks like it may work in a video card if I hot air it off the board, but I'd hate to scrap it if it has any reason to live. Thanks in advance for any info! …

When you splurge on that hard to find nostalgia, and finally do pay through the nose because it just isn't out there anywhere else. Then the seller can't pack. It comes broken, and all they want to do is have you return it, or worse no reply at all. If you open a claim the sites just tell you to …

Amazed that Davros and Garrett W were the only mentions of Descent. That was a freaking awesome release that blew my mind. Tomb Raider also stands out. Sadly I didn't get Duke for many years after. I really don't know why. ~TW

Okay, tried it out with a 35.xx mhz crystal I harvested from an old broken router. It will boot up and post but the hdd (ide onboard) will not load up. It works fine with the original 24mhz crystal. I think this confirms that the crystal is being shared and clocked down somewhere. The question now …

The following eBay listing is the same board. https://www.ebay.com/itm/Motherboard-with-N80 … rs/254530094154 I am going to try the suggestion of 32 and 40mhz crystals, because even 16 or 20mhz would be a victory in my quest. Thanks

I know that the i287-XL was intended to be 12.5mhz but many have said it can be pushed further as it is really a 387. It is my understanding that the clock will either be half or 66% of the original, but I'm not sure with board. NPU clock setting depends on CKM pin (#39) - if it's a logic level L …

Working on this machine again, and moving the conversation to a new post as my original one was about the 287 options alone and this one is going to be about everything I'm doing. This machine contains a motherboard with surface mounted 286-12. Here is a link to the board on stason. I have also …

Wondering if anyone has any specs or knowledge on the motherboard I am working with right now? It has a 24mhz crystal for the processor, and I am going to …

The DMA option appeared in 95B, IIRC. At any rate, it does not exist in 95 retail, and does exist in 95C. I suspect this will help if not solve the problem. Disk access on my 95A box cripples the box. E.g., during heavy I/O like boot-up, or software installation, or copying large files, pretty much …

I've got Win95 C. The option doesn't seem to be there under system / hard drive. Does that mean my Quantum drive doesn't support it, or that the OS doesn't have the option? I thought B had the option default off, but could be turned on, but can't seem to find anything on C. Thanks for any info! TW …
