Last weekend I visited a retro-computer fair. From a distance I thought I saw an Atari XL. Coming closer, it became clear it was something completely different.
There's remarkably little information to be found on the net about this little computer.
There's some information about its successor on Wikipedia:
I took a few pictures of the inside. Besides the usual 74LS logic, I determined the following chips on the motherboard:
Motorola MC6847P, Video Display Generator
2 x Hitachi HM6116P-4, 2048-word x 8-bit High Speed CMOS Static RAM (200ns), total 4kB
NEC D780C-1 (4 MHz)
Hitachi HM613128P (128K x 8 ((E?)P?)ROM) ), 16kB
