+      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."

+      Very interested datasheet on SBP0400!!! Please, if it is not difficult, to send this datasheet to my email: kolba1958@gmail.com.

+
+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.
