    Thanks for posting that. A bit of computer history I had never come across before.

    I remember being shown both the Intel chip and the TMX1795 on one of my visits to Datapoint (as a consultant for them), particularly the number of support chips needed to make the TI chip work properly in place of the TTL Datapoint processor. Apparently they never could get the Intel chip to work properly.

    Intel had to be dragged kicking and screaming to the table to do Datapoint's processor. Since Datapoint was Intel's single largest customer for serial memory, Datapoint had some significant leverage over them and threatened to take their business elsewhere. The first Datapoint 2200s had a serial processor and serial main memory ... the processor stalled waiting for the next requested memory location to shift around so, by rearranging your data and instructions, you could speed up or slow down your program.
