Today I placed an order for reproduction boards for my Mod 8, along with some new 1702A programmer boards (with bug fixes), and the latest version of my EPROM/PLA reader for the Arduino Mega. With any luck, these should arrive in a week and a half.

I removed the stickers covering some details on this Mod 8 board. Called a MAC-88-104-10, this appears to be identical to the Microsystems International Mod 8-4 ROM board, however it appears to be made by TSL.
Has anyone ever heard of that company before? Produced by Mini Micro Mart in 1976, their Universal LED Display Board (1088C) was originally designed as a debugging tool for their own operation. As the Mod 8 / Mod 80 didn't have a front panel, Mini Micro Mart flogged this as a display device for a front panel display in a Mod 8 Mod 80
. The card has three different edge connectors, the Mod 8 connector is the small one on the left. Presumably one of the others is a S-100 bus connector. If you have one of these, let me know. I would like to collect one. When I was around 11 or so, my parents bought me my first "science kit". It was a Logix-Kosmos Electrics kit. It was quite a cool kit. It advertised as "a complete electric lab" having "140 experiments". I don't recall if it actually did or not, but I do remember learning a lot with it. Some of the things you could build were a motor/generator, a speaker, a microphone (using carbon granules), a telegraph key and receiver, and a bell ringer. If I remember correctly, it was missing one or two of the small parts for some reason, but that didn't stop me from having lots of fun with it. I would love to get a hold of one of these again, just to build a few of these things to show my kids. |
