Joe's IBM 5100 Computer
What! You never heard of a 5100? Well it's not surprising.
Even though IBM called it a Personal Computer, they cost around
$15,000 in 1975! The model number 5100 indicates that it is
indeed the forerunner of the IBM PC (model 5150) and PC XT (model
5160) and all the ones that followed. One of the most unusual
features of the 5100s is that they could run BASIC or APL or
both. The C01 designation on my 5100 indicates that it came with
both APL and BASIC build-in and with a whopping 16K of memory!
