not famous as such, more like completely unknown actually.
In my youth, as I've already mentioned, I got very into
programming my TI99 and had a couple of my programs
published in Home Computing Weekly. Later I also had
a C64 program published by them, and a few very small
Atari 8-bit programs that I wrote for Atari User. I
still have the original magazines that they were all
published in and some of the correspondence from those
magazines about the programs.
Texas Invaders for the unexpanded
This was the first
program I had published and the thrill of seeing my
name and my program in a computer magazine was unimagineable!
It didn't matter that I got paid peanuts (£12.00!)
for the hours and hours of work that went into it; I
was published! It appeared in Home Computing Weekly
number 33, dated Oct 18-24, 1983.

which made it sound an awful lot better than it was,
along with several box-outs which HCW liked to include
with every listing giving details of how the program
worked, a list of variables and hints for converting
to other versions of basic.

Texas Invaders Revenge for the unexpanded
Light headed with
success, I submitted a few more programs to HCW, but
they were rejected as not being good enough for inclusion.
This was a bit demoralising, as I'd put a lot of work
into my programming and thought they were better than
Texas Invaders. Presumably the HCW editor had other
ideas. Undaunted though, I wrote a sequel to Texas Invaders
called, unoriginally, Texas Invaders Revenge. I submitted
this one and it was accepted! Fame again! All my hard
work was worth it (HCW thought it was worth £20.00
this time). Sadly, this was the last TI program of mine
to be published in HCW.

The invader starts off on the

It is under the protection of

shots at you with one of it's two powerful lasers.

doomed. But you can always play again.
Your laser has an automatic
