For what it's worth, my recollection from talking to Wilson is that
TEENY.EXE loader is Ron's creation.
But the original program was "TINY" and TEENY was more about the loader.
Though he may have modified it the original TINY beyond just patching it
up. I don't know.

Well no word from Ron huh.
I can say, as I'm sure everyone suspects, he is a very clever programmer. I
spent some time taking apart his TEENY.DO loader for TEENY.CO
It is quite a thing.  It is a 2 stage loader.  First a program simply coded
as hex ascii loads up stage one, which then reads back and loads up TEENY.CO
which is heavily encoded to enable re-location.
I didn't reverse engineer it all; all I needed to do was make a single byte
change in the 2nd stage data, to remove the SIM opcode from the resulting
TEENY.CO.

I have my own much less fancy loader now that creates NTEENY.CO at 62213,
and runs on NSC800.

Ron's ham radio callsign is still active, but I find no recent activity
on any of the ham radio sites that I generally visit.  Hope he's OK.

He has been notably missing for a couple of years. I was curious about his
whereabouts myself..

[M100] calling Ron Weisen

2020-10-09 Thread Stephen Adolph 
Hey folks,
Has anyone heard from Ron lately?
Is he on the list still?

I disassembled Teeny to fix it to work on Z80 and I'm mostly done, but it
would be nice to let Ron know what I am up to.

thanks
