We hate 2020!

Just when we thought 2020 couldn't get any worse! We were about to re-open after many months of being closed but then disaster struck when a mains water pipe burst and flooded much of the ground floor of the museum.
Sadly re-opening has now been postponed. Read More >>>

AES 7100 PC Model 203

AES Data Inc. was founded by Stephen Dorsey, a Massachusetts Institute of Technology-trained engineer in 1972. AES launched the AES 90 computer, years before Microsoft and Apple were companies. Marketed as a "word processing system," the AES 90 was really the world's first general-purpose personal computer. AES went on to grow to more than $200 million in annual sales.

On Sept. 1 1987 Kinburn Technology Corporation of Ottawa announced that it had completed the acquisition for $16.5 million of all the outstanding shares of AES Data Inc. of Montreal.

The AES 7100 Model 203 was primarily a word processor and was produced in 1983. The unit is approximately 26.5 inches wide, and over 16 inches deep - including the handles on the back for pulling out the motherboard.  The main box is about 4.25 inches high, with a 10.5" green phosphor monitor mounted on the base unit, connected with a swivel neck. 

The motherboard pulls out on a tray from the back of the machine. There is a 12-pin female port with a connection for a printer. The pins arranged in a 3x4 grid. On the motherboard, there is a Mostek Z80A, probably 4MHz.  There are three Z80A PIO chips, and two Z80A CTC chips.

This unit is in very good condition and together with the dedicated AES printer, manuals and training software was very kindly donated by Leonora Sheppard of Leonora UK, together with an AES promotional plastic bag and mug.
