Do three pedants define a plain obtuse triangle?
Sure, but you gotta promise to hold up your corner. ;-)

Yes, I think you are right. They may have been SOS ones. I know RCA made
them for some purpose way be then. They cost like the devil.

bad enough. I don't much like making hammers and straightening nails
either. I've been using MED on Windows, and VE (though I don't like it) on
*IX for some time.
The two best editors ever made are "credit" by Intel and the Wordstar like
IDE one from Borland.
Rich Grise said:As a matter of fact, I used "credit" (CRt EDITor) on one of Intel's MDSs,
back in the days when the guy who got a couple of TMS2716 samples had to
guard them with his life. Of course, in the colleges, they were giving
away 8086's like popcorn. I'm almost sure the MDS (microprocessor
development system) was an industrialized 8080/S-100. I was working on
triple-redundant Naval Ordnance systems. (I had dropped out of college, to
get a _real_ education.)
ICE-86 was an emulator for the 8086. It copied mostly the commands of
ICE-80. You could load the program into the RAM iside the ICE-86 and run
it on your target hardware. The load operation took (on my project) 4
hours[1] to load the code. If you loaded a small program and then
transfered the real code via a RS232 link it was much faster so that is
what we did.
[1] No kidding folks.
After the "series 3" came the "series 4" which led us to state that each
version is better than the next.
The operating system was something called ISIS. It was a more advanced
operating system than MSDOS was on the day the PC came out.
John Larkin said:We just cross-assembled uP code on a DEC timeshare system
(later, on a
PC) and ran a tiny "monitor" (hex loader/debug thing) on the target
itself. That was a lot more efficient than buying a monster
soon-to-be-obsolete ICEbox.
Nowadays we cross-assemble on a PC and test with a background debug
pod running off an ebay laptop. The whole chain costs about $600,
roughly $100 in 1972 dollars.
