The TC-900 was a small, solid-state, two speed, battery/mains operated recorder with a maximum spool size of 3″ and featured the Sony-O-Matic automatic recording level circuitry.
Boldly styled in red plastic, the recorder had a detachable fold-down
lid with a clear window so that tape progress could be viewed and also
to see how much tape remained (no tape indicator was provided).
This was a rugged, well-constructed machine with a substantial flywheel
and positive controls.
The price of the TC-900 when new (in the UK) was £33 12s.
