ELZET/K
ELZET/P
BCS
All documentation is in German.
The ELZET/P is a luggable CP/M computer that from the outside looks very
much like a Kaypro II. The floppy drives could be one under the other like
the Kaypro, or could be vertically-orientated side-by-side. The drives are
80 track quad-density with 800KB capacity.
Behind the drives is a cage that can hold up to 8 slots that plug into a
small motherboard.
CARDS: (some are optional)
- Floppy Disk Controller: choice of FDC 2: (basic) or FDC3 (also has 128K RAM)
(main chips are PIO, DMA, MB8877A)
- Dynamic RAM: choice of 64k or 256k
- Centronics (contains PIO, CTC)
- EIC (contains PIO, DART, Z80B)
- Experimenter board (contains PIO, CTC)
- Video (contains MC6845, 2k vram, 2k attr-ram, chargen roms, 15MHz xtal)
- CPU (contains Z80, SIO, PIO, 4MHz xtal)
The keyboard plugs into the front by using a stereo audio plug, like you
have on a modern computer's line-out jack. There's no internal information
for it.
The ELZET/K is a similar computer but is a slightly smaller form factor.
The BCS is a box that can be used to convert over 300 floppy-disk formats.
