This is the Sony TC-377 I was using in 1976
I then bought the TEAC 144 Portastudio when that came out. Later upgrading it to the 244 which had built in noise reduction (gasps of amazement).
I then jumped up to 8 tracks with a Fostex Model 80 and a Revox B77 HS half track for mastering. My compositions were based around the output of a BBC Model B computer running the UMI MIDI sequencer connected to a the inevitable Yamaha DX7 and Roland bits.
A few years later I bought my first PC and, after messing with Voyetra Sequencer Plus, eventually discovered Cakewalk products.
