The Basis 108 was a computer ( Apple Clone ) that was largely compatible with the Apple II and was manufactured by Basis Microcomputer GmbH, based in Münster (no longer in existence).
The Basis 108 integrated many functions that first had to be retrofitted with an Apple II using expansion cards. In addition to the 6502 processor, there was also a Z80 on the motherboard, which made it possible to use CP / M as the operating system. The text mode could display either 40 x 24 or 80 x 24 characters, a serial and a parallel interface were also available. The colors of the low resolution graphics mode were sorted by color, which was more logically structured in terms of structure, but made the graphics mode practically unusable for Apple II programs due to the incompatibility of the color table with the Apple II. The RAM of 64 KB could be upgraded to 128 KB.
What was striking about the base 108 was its massive and heavy metal housing. In contrast to the Apple II, the keyboard was not built into the housing, but designed as an external keyboard. For this purpose, up to two floppy disk drives were integrated in the housing.
At least 25,000 of the base 108 were sold.
