What is this? Post Photos of Mystery Items Here (vintage computers only)

Of course, unless I get a chip tester and can confirm that it's working which really could raise the value with provided proof of course.
 
I thought possibly there was a ic chip tester that I could just test the chip. Not the board itself haha my bad for rookie knowledge
 
Anyone can help me with this? Looks like some early / prototype LANtastic card to me.

Highly doubt that.

Z80, BIOS, and DB9 is typical for LANtastic. But the card does not look like a finished product.

I guess I need to dump the ROM and have a look at that.
 
CP/M compatibility card? With only 2 KB of RAM, no. I also think somebody removed parts: most holes are filled with solder but there are enough not filled plus the way things look. Bit intriguing, bottom-right looks like the place for a 25-pin D-connector. Also partly (de)soldered but no hole in the bracket.
 
Those holes are filled with solder because it was wave-soldered, which means they were intentionally empty. That entire bottom half with the D25 connector was simply not used. This looks like a production card (prototypes don't usually get version 2 firmware!), even if there is no text on the board. Also the sticker apparently has a "1" on written on it that is almost an upside-down "V", which I think is a uniquely German handwriting style. So at least that chip was programmed locally.

If you look at the solder side, it should be easy to confirm that it was wave-soldered, which also is not a thing in prototypes.
 
Correct, there are no removed parts. The card is "complete" the way it is.

prototypes don't usually get version 2 firmware!
Click to expand...
Owning tons of prototypes of all sorts I can tell you that many even get the final retail firmware in order to use them instead of trashing them.

It's impossible to tell if the EPROM matches the date of the card. It was probably updated much later, as you would not have a hand-written label on a production card either.

Anyway, going to dump the ROM later this day.

It is an interesting card. Looks like it can receive data from the port and store and process this to place on the latches... So it could just just about any kind of I/O function from counting events to controlling something.

2K of ram isn't a lot though - so it's probably acting in an embedded manner.
 
It is listed on page 7 of the PDF ("Ergi EDO 124"). ERGI is written on the card above the large blue cap.
