General Information

The IBM JX - the mature brother of the IBM PCjr
IBM Model 5511


IBM failed to capture the home computer market in the USA with the IBM PCjr. So they put their tail between their legs and tried again with the IBM JX in Australia & Japan. Once again, they failed to interest the consumers with this architecture.

Basically, it is a crippled IBM PC, with proprietary slots and a few nifty features. It has an infa-red keyboard, a light pen port, 400k 3.5" drives, two cartridge slots and a three-voice sound chip. Sadly, it fails to run most IBM PC software without modification.

The keyboard you see attached to the JX in the above picture is the Enhanced Keyboard. The Standard Keyboard can be seen below.
