In some old video on YouTube a few years ago, I noticed a curious computer from the end of the 70s - early 80s. In the rack (half height), typical of minicomputers of those years, there was a 14" hard disk, an impressively massive power supply and a computer itself on several printed circuit boards.

If I do not change my memory, there was a system based on i8080 or Z80 CPU, peripheral controllers (printer and terminal), a hard disk controller on SSI/MSI chips and a certain hardware database accelerator with bit-slice ALU.

In general, a certain analogue of the middle-class systems from IBM, produced by some little-known USA company (start-up of those years probably).

Unfortunately, I did not succeed anent of anything about this system, and I ask for help. Looking for the history of this computer, description, documentation... Or at least a name for searching in Google.

    Sure it was an 8080? The description sounds much like business computers from the 70s, like MAI et.al.

  • I'm not sure that was exactly the i8080 processor. But about the combination of an 8-bit processor itself (not terminal) and bit-slice accelerator I, however remembered well. But yes, somehow it looks like MAI BB line (Microdata corp) computers. Hm... Jan 2 at 16:54
  • Unfortunately, I did not succeed anent of anything about this system 'succeed anent' doesn't make sense - please can you edit and correct this, to clarify what you mean. Thanks.

    Sounds like an MAI BASIC/Four minicomputer - except that bit-slice processor in that case wasn't a "database accelerator" it was the actual CPU - custom instruction set (bytecode) for running BASIC (and another custom instruction set, bytecode, for running the compiler/decompiler which was written in TREE-META). I don't remember there being an 8080/Z80 in there (don't remember one way or the other) but if there was it would have been a (multi-) terminal controller.

    (Not sure what you meant by "Microdata Corp" ... explain?)
