Sorry, but after spending more than a half-century developing software
(link in sig),
I'll see your Spectra 70/45 and raise you an RCA 501 and 301. )
You win - besides, the 70/45 was just a thin film approximation to a
360/30 (same instruction set and I/O devices, but had a sexier front
panel)

By "thin film", do you mean it also had the cros (capacitance read only
memory) instruction set as the 360/30? It was punch card size mylar
with copper traces that were punched out on one of four sides of a
squeare or some such. The first time I saw the 30 power on and the cros
"pump up" to push the cros punch card ros together, I wondered "WTF"?

Then there was the 360/40 with the "tros" micro programmed instruction
set...

Then there was the 360/75 with no microcode.

That's the one I started with in '64.

Must have been a first. The /360 was announced in '64. I didn't use the /75
until '67 (I was a Junior in high school .

It was an IBM punch card I/O Fortran IBM machine we used in college in
'64 - can't remember the IBM model number.

Akshooly, it was '66 when I went to work for IBM and went to 360 OS
school in Endicott (DOS), and then Poughkeepsie (OS). Classrooms full
of ashtrays and smoke so thick, you could barely see the blackboard and
the instructor with his [bad] hairpiece. Cigs were $0.35 a pack in the
vending machines in the hallways with 2 cents taped to each pack making
them $0.33.
