Unknown card

Post by ruud »

Hallo allemaal,

I bought a C64 inside a 19" case dedicated for packet radio (I think). Inside I found IMHO a VIC-20 card. The funny thing is that only the 'extra' electronics was used. These electronics were not connected to the pins of the expansion connector in any way (AFAIK), only the EPROM was and that wasn't used at all.
On the back you'll find the words 'COMPUTER-WORLD' and 'DK20'. Remark: there could have been another character before the D but a hole has been drilled on that place.

Have a look at http://www.baltissen.org/images/img_0037.jpg
Sorry for the quality but this camera is 5 years old and doesn't have a zoom function.

Has anyone an idea what this card is? Thanks for any input!

Code: Select all

I haven't seen this card before.

C64s were often used by ham radio operators for automated control of repeaters and / or phone patch systems.

The eprom likey has the application burned to it.

How about a dump of the EPROM? That should have something in it that would identify it.
