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.
