Oh, I did catch the 'first magnetic storage' part of the post - was just off on the related tangent - por supuesto.
My first 'magnetic storage' computer was the TI-59 - which, although called a 'calculator' - really was a programmable computer. Thought I had it last year of college - but the history sites say it didn't come out until May 24, 1977. Was pretty sure I bought it from the TAMU bookstore - and it was tough deciding between the 52 and the brand new 59. That would have been in spring 1976 however, a full year before the sites claim it was released. Possible CRS kicking in - revisionist history of an addled brain.
Used it for many years - did eventually buy the printer to go with it. Quite useful back then.
I looked at and thought about other computers over the years - the TRS80, Tandy had one that you could build yourself (paper tape), and so on. Passed on all those - had enough computer stuff at work - and the home models would not have been compatible - so passed until much later in the game of a full bore 'home pc'. The TI-59, interestingly, was a 4-bit processor. *lol*


Finally, brethren, whatsoever things are true, whatsoever things are honest, whatsoever things are just, whatsoever things are pure, whatsoever things are lovely, whatsoever things are of good ...
