Homebrew goodies from the past ?

That FigForth cartridge is built on a TI EGROM cartridge board.

 

On the Logo 1.1 Deutsch, it didn't come in a standard package. I received the cartridge (with a small, square, handwritten label), a disk, and a photocopy of a preliminary manual in German.

Good idea , for me no problem.... but think i have to ask R.Ziegler first before , anyone who have an email or something to get in contact with him ??

 

Hmmm, I don't know of any Ziegler before. I read from him the first time. But I found a web page from one who's name is Ziegler (but with no content and no email). :-(

Yes--those are the parts for an EGROM Box. There are two different versions of the larger circuit card, but they are functionally identical. The cartridge on the cable holds the cartridge ROM (if any) and the sockets in the box hold the code for up to five GROMs (all chips for both device parts are TMS2532s). The GROM logic is on the larger board as well. I have both types.

 

The EGROM cartridge board is actually a totally separate device, basically a cartridge board with all of the logic on it to simulate GROM (like the Heiner Martin board).

I could 3D-print the 9914er

I completed the layout for this device and the attached cartridge board a few years ago. I haven't tried to read out the PALs yet--a necessary step towards an attempt to reproduce them. I'f the PALs are readable, I may make a small run of them. . .probably no more than 10 or so.
