# SQ Notes

SQ Notes column presenting the planned (but never released) Timex [TS 2060 System Expansion Unit.](http://localhost/product/bus-expansion-unit/) Covers the full specification as described in the QL Technical Manual: memory expansion to 16MB via bank switching, Centronics parallel port, RS-232, 80- and 64-column video modes, RGB output, up to eight Microdrives, local area network support, CP/M mode, and audio output. Lists the extended BASIC commands planned for the unit (STREAMS, CHANNEL types, CAT, FORMAT, OPEN#, etc.) and reproduces the Spectrum Interface I system variables table (addresses 23734–23792). The author advocates using Sinclair mode over Timex mode for maximum compatibility.
