Do you know what the name
TRS-80 Stood for?
The name TRS-80 stood for two
things:
• TRS stood for Tandy Radio Shack,
the company that created the TRS-80.
• 80 was taken from the Zilog Z80,
  the processor used in the original
  TRS-80 Model I.

Tandy continued to use the TRS-80 name for their future computers, even for ones that didn’t use a Z80 processor.

For example:
• The TRS-80 Color Computer 1 used
   a Motorola 6809
• The TRS-80 Model 16 used both a
   Z80 and a Motorola 68000
• The TRS-80 Model 100 used an
   Intel 8085
• The TRS-80 Model 2000 used an
   Intel 80186

Tandy phased out the TRS-80 name
after the TRS-80 Model 2000, in 1983.
