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. ..Steve On Fri, Oct 9, 2020 at 2:01 PM Stephen Adolph <[email protected]> wrote: > 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 > Steve >
