The first complete, low-cost microcomputer system for business, home or education - TRS-80 Technically, it wasn't - the Commodore PET was launched several months before the TRS-80 at the January Consumer Electronics Show and as such was the first of the "1997 Trinity" (which also included the Apple II) to be revealed to the public. However, the TRS-80, or "Trash 80", launched in August, was the first to market and the first to retail in significant numbers and proved quite popular, selling over 100,000 units in its lifetime. It was Z80 based and had 4K memory as standard, and retailed for $600, or about [[400|1977]] in [[now]] terms, making it cheap compared to the Commodore PET and the Apple II.
