The success of the TPA1001 has brought fresh blood into the MSZKI: young graduates started to work there, one of the new tasks was to re-implement the 1001 using 74-series TTL ICs. The new machine completed the final testprogram (called T2) on the 15th of March, 1971. for the first time: the TPA-1001/i was born (the name has been changed to TPA/i or TPA-i later). The first series was called the "high i's" bacause of their mechanical construction. The picture on the top of the page shows such a machine, you can see one opened up on this picture. The manufacturing of this enclosure was too complicated and expensive, so the later /i's had a redesigned clothing, which looked a lot like the original PDP-8s (and the later TPAs).
