Roll into #DOScember 2021 with an AT&T PC 6300 that has some very, very rare upgrades! As far as I'm aware, there are NO IMAGES of these upgrades (no good pictures, anyway) anywhere else on the Internet. This is a Tales of Weird Stuff exclusive!
00:00 Intro
01:24 The CRT monitors
03:55 1024 HP Graphics Board box
07:10 High resolution graphics board!
09:03 Memory expansion board!
11:12 8087 math coprocessor
11:27 RAM on the motherboard
11:56 Vintage battery replacement
12:50 Mystery transistors?
13:34 TURN IT ON!
15:14 Closing remarks
My previous AT&T PC 6300 video: youtube.com/watch?v=E-PdRY4QseQ
As I scan the manuals and get the software uploaded, I will add links here.
The monitors:
- CRT 318H is the color display that uses the older interface.
- CRT 327 is the "high resolution" monochrome monitor that uses the 1024 HP Graphics Board.
The graphics board is the PC Image Director Integrated Graphics Package Graphics Board Model 1024 HP.
The RAM expansion board is a Fastcard by Thesys. The only markings on the board are "Assembly 39 C Rev. B". I was mistaken in the video. There is a picture on page 33 of the June 1985 issue of Creative Computing (archive.org/details/creativecomputing-1985-06/page/n33/mode/2up).
Looking at the motherboard again, it clearly has 256K installed, and the memory board has the remaining 384K to provide the full 640K.
