Home computer, 1980, Tandy. The TRS-80 Color Computer, or "CoCo", was Tandy's home computer, unrelated to the Z80-based TRS-80 apart from the name: it uses a Motorola 6809 with the 6847 video chip and Microsoft Extended Color BASIC, and it was sold in silver-grey and later white cases from 1980 to 1991 in three generations. Its 6809 processor and the OS-9 multitasking operating system made it a favourite of hobbyists, and the Dragon 32 was a clone of it. The exact generation of this unit is to be verified.
