 From Wikipedia
Beim Basis 108 handelte es sich um einem zum Apple II weitgehend kompatiblen Computer, der von der Basis Microcomputer GmbH (nicht mehr existent) hergestellt wurde.
Der Basis 108 integrierte viele Funktionen, die bei einem Apple II
erst über Erweiterungskarten nachgerüstet werden mussten. So befand sich
neben dem 6502 Prozessor auch ein Z80 auf dem Motherboard, so dass die Benutzung von CP/M
als Betriebssystem möglich war. Der Textmodus konnte wahlweise 40 x 24
oder 80 x 24 Zeichen darstellen, eine serielle und eine parallele
Schnittstelle waren ebenfalls von Hause aus vorhanden. Der
Arbeitsspeicher von 64 KB konnte auf 128 KB aufgerüstet werden.
Auffallend beim Basis 108 war sein solides
Metallgehäuse. Im Gegensatz zum Apple II war die Tastatur nicht im
Gehäuse mit eingebaut, sondern als externe Tastatur ausgeführt. Dafür
waren bis zu zwei Diskettenlaufwerke mit im Gehäuse integriert.
-----------
This professional computer was compatible with most of the hardware and software designed for the Apple II.
It could run under DOS 3.x, but thanks to its second CPU, a Z80 processor, it could also run under CP/M.
The Basis 108 had 128 KB RAM, (two switchable memory banks of 64k).
Two 5"1/4 disk-drives (Apple compatible) could also be mounted inside
the computer. In the picture, these are one Apple Disk II drive and one Siemens
FD-100-5.
The Basis 108 was a good Apple II compatible machine with a lot of
options built-in (80 columns, disk-drives controller, CP/M,
high-resolution graphics), and was cheaper than the equivalent Apple
system...
A year after introduction, the Basis Junior was presented at various
different electronic shows. It was basically the same computer but with
only 64 KB RAM (with optional expansion to 128k).
