IBM VGA ROM

We have only one IBM VGA ROM revision, dated October 27, 1986, from an IBM PS/2 Display Adapter. Which, BTW, has to be one of the most confusing product names ever, since the adapter was an 8-bit card designed for ISA machines, not PS/2 machines.

To (re)build the JSON-encoded IBM-VGA 1986-10-27 ROM, run the following FileImage command:

fileimage.js --file=1986-10-27/IBM-VGA.rom --output=1986-10-27/IBM-VGA.json5 --comments

The disassembled contents of the 1986-10-27 ROM from the IBM PS/2 Display Adapter is available here.
