Yes indeed. My first assembler program converted from a teletype code we had at school to the Elliot code used at the local 6th form college of technology.
Worked first time (unlike someone else that attempted it), partly because I triumphantly re-invented the concept of FSMs :)
Yes, I felt that way about ASCII, when at university.
Yeah, but I was in the fifth grade in 1970. ;) The Nova thing was in 1980.
My acquaintance with teletypes was during my brief interest in ham radio, back in my teens. I'm still interested in radio to this day, just not in operating my own station.

In 1970, I was fresh out of the university with my MSEE.
Welcome back. The bands are still there.

The stories I heard back in the day was that the 68000 family had only the CPU, but not the flock of necessary support chips, while the 86000 family was more complete, making implementation of a motherboard quicker, simpler, and cheaper.

That's the HP one, right? Also called the 9816?

Hi Phil,
Yes, it is the HP box. I also have a dual floppy drive and a Hard Drive storage unit. All connected via the HPIB bus.
The first system I learned on was the SWTPC 6800. It had a dual floppy made by Smoke Signal Broadcasting. Ever hear of Tom Pitman and his Tiny Basic interpreter? It ran in 1.3 K of ram. Ram was very expensive back then.
My HP 35665A DSA has a 9826 in its guts, so I actually still have one too. One of these times I should get out my floppies from grad school and see if any of my old programs are still readable.
I heard of Tiny BASIC and Small C, but never used either. My earliest programming experience was with a card-programmed HP calculator running HP Educational Basic, owned by the Vancouver School Board, iirc. You programmed it with a #2 pencil, just like a SAT test. I remember that erasing was a bit iffy--it would sometimes read both the old and the new mark.
Besides calculator programming and the Nova, at UBC I used IBM Fortran G and H on an Amdahl 470 V8 running the Michigan Terminal System (MTS) for time sharing. IBM 3270 terminals were a big improvement over coding sheets and keypunching. I also did a little work on a weird little nuclear instrument system by a company whose name I forget but would recognize--it was all made of LS TTL and ran an interpreted FORTRAN called Flextran.
Cheers

No, that should read "could buy them (Intel) if (Intel) went South. And it (Intel) did and they (IBM) did.
The 68000 had a bunch of support chips, as well. As noted elsewhere in this thread, IBM's Instrument Systems System-9000 used the 68K. They were a much smaller user, though. The market for PCs was HUNDREDS OF THOUSANDS. ;-)
The 68K's legacy precedes the 68K.
OTOH, I never minded an asymmetrical architecture. Conventions tend to hem in register use anyway, so leaving out the hardware (and code space) for an orthogonal instruction set made sense.
That seems like excessive caution when projected sales was only 20000 units.

Except that they needed Intel for other products.
What it seems to you, now, isn't history.
You had paper tape. We only had holes.
-- Reinhardt
Our papertape had lots of holes. (1969,pdp7 8K 18 bit memory, papertape or dectape run environment) I even remember my first line of fortran. I spotted an error in an if statement. Data input:rolls of papertape from an instumented car. Imagine an experimental driver with a full speed running papertape unit in the back of the car. Horrible......
