You're probably talking about Aliens! released in January 1980?
- I was introduced to BASIC early on in elementary school on
these clunky school-maintained terminals with printed text on
paper rolls (no monitor). This would be in the early 1970s.
- In middle school again we had access to the same clunky
terminals...this time you could sign up for your own account
and create/store BASIC programs of your own making.
- In 1978 I talked my dad into getting me a PET from
Mr. Calculator in Town & Country Village. I remember it
was $795 and the wait time was insanely long due to high
demand. After looking over materials for the PET and the
TRS-80 I decided on the PET because I thought the graphic
characters looked pretty cool.
- I acquired a 3rd party game...Seawolf I think it was...and
being written entirely in machine language really impressed
me. My curiosity led me to purchase the CMOS 6502
reference manual listing all the various commands and
status flags used by the processor.
- If memory serves, probably I wrote the game first in
BASIC, and then replaced parts of BASIC with machine
language (using SYS calls) until eventually the entire game
was in ML. To do this I used the monitor program available
on cassette tape that allowed you to enter hex codes
directly into memory. Coding this way would be seen
as insane by today's standards but heck I was still in
high school and went with the tools and knowledge I had.
- I submitted the game to Cursor Magazine in 1979, and
I think got a check for $135.
