This is a vintage CPU board from around 1984 based on markings of the board. The function is unknown. It is labeled:
adps Made in W. Germany
SBS 189.02
It appears to be a single board computer with many interesting and vintage IC\'s on board.
Some notable components are:
- Mostek MK3880N-4 (Z80 CPU)
- Mostek MK3882N-4IRL (Z80 CTC)
- Mostek MKDART4N-4
- Zilog Z8420A (x2)
- Texas Instruments TMS9937NL (England 8406)
- WDC2143PD
- Synertek SYP1793-002
- Toshiba TMM2016P
- EPROM labeled \"Soabar CDS\". This might be a 2732 EPROM
The date ranges on the chips are from 1983 - 1984.
There are 2 edge connectors on the board. It appears to be made by a company called \"adps\" from Germany and may have a model # as SBS 189.0.
I am unable to test this board so be aware I can\'t guarantee operation or that the individual chips may be working. It is in generally good shape cosmetically.
The board measures about 9.5”x6.5”.
