Olympia BOSS
|
||||||
|
Made in Germany around 1981
|
||||||
|
|
||||||
|
The BOSS series was not a great success, as its members differed too much to be compatible:
|
||||||
|
First they were 8085 based, later machines used a Z80A.
|
||||||
|
|
||||||
|
Other distinguishing features were the capacity of the disk drives:
|
||||||
|
|
||||||
|
BOSS A: Two 128K floppy drives
|
||||||
|
BOSS B: Two 256K disk drives
|
||||||
|
BOSS C: Two 600K disk drives
|
||||||
|
BOSS D: One 600K disk drive, one 5 MB harddisk
|
||||||
|
BOSS M: M for multipost, up to four BOSS machines linked together for up to 20MB shared harddisk space
|
||||||
|
|
||||||
|
Olympia favoured the French Prologue operating system over CPM (cf. Olympia People PC) and supplied BAL
|
||||||
|
as a programming language with it.
|
||||||
|
|
||||||
|
Video is 80x28
|
||||||
|
|
||||||
|
There are no service manuals available (or no documentation in general), so everything is guesswork.
|
||||||
|
|
||||||
|
- Ports 0x80 and 0x81 seem to be related to the graphics chip and cursor position
|
||||||
|
The rom outs value 0x81 to port 0x81 and then the sequence <column> <row> (?) to port 0x80
|
||||||
|
|
||||||
|
- The machine boots up and shows "BOSS .." on the screen. Every keystroke is repeated on screen.
|
||||||
|
If you press <return>, the machine seems to go into a boot sequence (from the HD, probably)
|
||||||
|
|
||||||
|
The harddisk controller is based on a MSC-9056.
