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.
