Summary: Microtec stuff slow, but very useful


Concerning the Microtec stuff, I found that although the package was indeed
slow (Vax 750 under VMS), it was extremely useful in my application.
In fact, we had a CAD system running off the same VAX, and when circuit
layout was happening, simulation which normally happened at a human-
readable speed slowed to 1-line-per-minute action. I usually scheduled
lunch for those times.

My task was to get a pascal p-code interpreter running on an 1802 system that
hadn't been built yet. We did have Microtec's 1802 assembler & simulator
programs, however, and I was able to get the program written while the
hardware was being developed and built.

The real beauty of the whole scene was that when it came time to blow an
EPROM with my 2k of never-seen-a-real-machine 1802 code,
		IT WORKED FIRST TIME !!
At the time, this didn't amaze me, since I had simulated the code to an 
incredible degree.

However, if you ever find yourself in the position of
having to write a large piece of software for a small/prototype machine,
get and use a simulator, it saves an *incredible* amount of re-blowing
EPROMS and suchlike.

(no, I don't work for Microtec)
