Texas Instruments Professional Computer -- SUPER RARE #DOScember

Can it pass the feared "smoke test"? As a part of #DOScember, John takes a look at a piece of his childhood: a super rare Texas Instruments Professional Computer from 1983. This is a non-compatible MS-DOS computer that attempted to compete with the IBM PC by building a better machine, and got crushed in the marketplace by Big Blue. This particular machine was stored in the warehouse at Computer Reset in Dallas, TX for over 30 years. #DOScember
