Hi to all,
I'm looking for the schematics (or the cards themselve)
of the DCE (_D_igital _C_ontrol _E_lement)interface cards
that where used in a microcontroller system.
Also known as _R_eel _W_orld _C_ards ... or RWC-cards for short)
It was a commercial 'industrial' product in the late 70's by the
company DAI (_D_ata _A_pplications _I_international. The same
company that made the DAI-personal computer in the early 80's.
The company was taken over by 'INDATA'
In the meanwhile ... the company doesn't exist anymore. A extensive
web-search came out negative.
The interface-bus was/is based on a 8255 PPI device.
Same cardnumbers to (hopefully) ring a bell for someone
* RWC-D12 (isolated Digital interface)
* RWC-AI16 (analog input card)
* DCE-PRG (EPROM programmer card) .... this one in particular...
I do have the designer's manual ... but this only has a functional
description of the cards ... not the schematic's.
Helpfull information, links, about this subject, will be rewarded with a
famous belgian beer of your choise!!! ;^)
