Two More TIGAs

Since some readers appear to enjoy identifying prehistoric graphics cards, I thought I’d post photos of two more TIGA boards from my junk pile. I know what these are, but do you? One of them ought to be fairly easy …Continue reading

Another Vermont Microsystems Board

My junk pile turned out to contain another board by Vermont Microsystems, Inc. (VMI), probably no less exotic than the mystery board. This one is a Microchannel board built around an Intel 82786. An in this case, VMI was kind …Continue reading

Have You Seen These Cards?

While cataloging my junk pile, I came across two graphics cards that I could not identify. Both are high-end ISA graphics accelerators from the early 1990s and both utilize Texas Instruments GPUs (long before the term “GPU” was first used, …Continue reading

ISA bus 8514/A?

During the development of the 8514/A, IBM clearly had ISA-based adapters. A proof of this may be found in the source code for the Windows 2.x setup program (part of the Binary Adaptation Kit, or BAK), which among other things …Continue reading

The XGA Graphics Chip

After covering the 8514/A and its clones, it’s only appropriate to write a few words about the XGA (eXtended Graphics Array), IBM’s final attempt at establishing a PC graphics hardware standard. The XGA was introduced on October 30, 1990, about …Continue reading

S3 Graphics Accelerators and the 8514/A

The previous article about the IBM 8514/A graphics accelerator and clones did not mention S3’s chips because S3-based graphics cards were never 8514/A compatible, unlike the ATI Mach 8 and Mach 32 chips and others. However, the relationship between S3 …Continue reading

The 8514/A Graphics Accelerator

On April 2, 1987, when IBM rolled out the PS/2 line of personal computers, one of the hardware announcements was the VGA display chip, a standard that has lasted for 25 years and counting. While the VGA was an incremental …Continue reading
