Robotron A7150
04/10/2009 Skeleton driver.
http://www.robotrontechnik.de/index.htm?/html/computer/a7150.htm
http://www.tiffe.de/Robotron/MMS16/
- Confidence test is documented in A7150_Rechner...pdf, pp. 112-119
- Internal test of KGS -- in KGS-K7070.pdf, pp. 19-23
To do:
- MMS16 (Multibus clone) and slot devices
- native keyboard
- A7100 model
