'the first IBM-PC' (even if we accept it's a 5150 of some kind)? Any 5-slot

later 64K-256K board in them). Can it have disk drives (remember, the
original spec allowed a cassette-only machine). Does it have to have only
IBM expansion cards? Only IBM expansion cards that were in production
when the machine was made? Different people would answere those questions
in different ways.

Did IBM ever really put out a cassette for the 5150's ? Knowing "Big
Blue"
that must have been a very impressive and expensive tape-mchn. How was this
port accessed ? Does anyone know what " hacks" were done or possible on
this I/O ?
