TA 1000

from Wikipedia, the free encyclopedia
Data station TA 1069, DB Museum Nuremberg

The TA 1000 computer was a medium-sized data technology machine from Triumph-Adler . In 1973 Triumph-Adler started series production of the TA 1000. TA sold over 10,000 of these machines, a respectable number at the time.

CPU

CPU board (AAB 01)

The central unit of the small computer TA 1000, with which the breakthrough in the IT business of "medium-sized data technology" was achieved in the early seventies, was bought by TA boss Gerd E. Weers for a few million marks from Otto Müller , the boss of the Computertechnik company Müller (CTM) in Constance. Otto Müller created an arithmetic-logic unit (ALU) from two SN7483AN (4-bit adders), two SN7400N, two SN7486N, four SN7450N and eight SN74H52N modules, and one from four SN7475N and eight SN74100N modules Register set and many other TTL logic modules the necessary control unit , so that an 8-bit CPU with a 16-bit address bus was created on a 28 cm by 30 cm printed circuit board from a total of 109 ICs (including a 4-pin threshold switch) .

Storage

RAM board (AAC 04)

The memory was a double-width board with 4096 bytes of core memory, later SRAM memory. The CPU could address up to 64 KByte with its 16 address lines.

operating system

ROM board (AAE 02)

The operating system (firmware) was modular: logic circuits with sockets for EPROMS were mounted on a firmware board (same size as CPU). Depending on the intended use, the EPROMs type 1701 z. B. plugged for a printer or a tape recorder. The operating system kernel was actually an interpreter for assembly codes and took up 1 KB in the main memory.

Periphery

In the beginning there were IO boards (input, output boards) for

  • Keyboard,
  • Dot matrix printer,
  • Paper tape reader and
  • Punch card reader,

then

  • Cassette tape drives

Tickets came later for

  • 8 inch floppy disk,
  • different printers,
  • Magnetic stripe booking cards and
  • an IO card for connecting an external dial-up modem (this was provided by the post office).
  • a display

Later there was shortly before the series was discontinued

  • a 14 "hard disk / removable disk with 12 MB
