Almost no information about this 'computer' which was probably the first microprocessor trainer Texas Instruments produced.

The system held two chips, a quad-Nand 74279 logic chip and a 4-bit SPB0400 processor which was the first processor made using the VLSI process technology.

One programmed it through various switchs, results were displayed on LED diodes.

Thanks to Steve Perry for information and pictures.

We need more info about this computer ! If you designed, used, or have more info about this system, please send us pictures or anything you might find useful.
