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.
I have the original 57-page Data Manual from October 1976 for the SBP0400A and SBP0401A 4-Bit-Slice I2L Processor Elements. This is contained in TI''s December 1977 Bipolar Microcomputer Components Databook. The book also contains the full revised Data Manual for the SN74S481 / SN54S481 / SN74LS481 4-Bit-Slice Schottky Processor Elements. I can scan and post these if anyone needs them.

I'm looking for to purchase the "operation manual" and/or circuit diagram from Texas LCM-1001. I tried to find the SPB0400 4bit uP datasheet but I didn't. I intend to make a LCM-1001 emulator on PC. Thank You!
