Tandy 1000 RSX

The Tandy 1000 RSX was the final and most conventional member of the 1000 family, using a 25 MHz 386SX, Super VGA, AT-compatible IDE and 16-bit expansion. The RSX/HD included a factory hard disc.

It completed Tandy’s progression from PCjr-inspired home computers to a broadly standard multimedia PC, after which the distinctive 1000 identity disappeared.

Notable Features

• Processing is provided by Intel 80386SX at 25 MHz.
• The standard memory configuration was 1MB standard; expandable to 9MB.
• Display hardware provided Super VGA with 256KB or 512KB video memory.

Historical Significance

• It completed Tandy’s progression from PCjr-inspired home computers to a broadly standard multimedia PC, after which the distinctive 1000 identity disappeared.
• Storage-only and minor motherboard revisions are documented on this page rather than treated as separate products.

Collector’s Notes

• Confirm the catalogue number, processor, memory and drives because similar Tandy cases were sold in several configurations.
• Original DeskMate or system disks, keyboards, monitors and Radio Shack documentation add historical value.
