TDK DC-90
Little is documented about the TDK DC-90. The one clear sighting in the indexed period literature is a New York mail-order ad in Audio (June 1980, p.131). The DC-90 went for $14.90 per ten-pack, plus $3 shipping - about $1.49 a cassette. The same ad prices TDK's SA-C90 at $29 per ten and the SA-C60 at $21. That puts the DC-90 at the cheaper end of that dealer's TDK stock. A later Audio classified (November 1981, p.90) lists a "D-C90". It may be this same model with sloppy OCR spacing, or it may be TDK's separate D series. No scan has confirmed which. A High Fidelity ad (December 1981, p.143) shows the SA-C90 at $2.99, which gives a rough idea of where the DC-90 sat in the lineup, price-wise.
That's about all the record holds: no specifications, no production dates, no editorial reviews. If you've got a box, a J-card, or a 1980 dealer catalog that shows one, the Archive would like to see it.
