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→
