Heh heh El Hefe, I think you forgot one instruction:

But, being honest, I never programmed an Atari 65xl with BASIC. I do programmed BASIC for Commodore 64 and MSX.
I'm quite fanatic of this old stuff... I had my first computer when I was 3 years old, it was a Spectrum Sinclair. After that I had a Commodore 64 with a 1541 disk drive (I also used cassettes, but not with a datasette but a standard tape recorder), a MSX compatible computer made in my country (it was a Talent DPC-200 with a 5 1/4 double density disk drive).
I still remember when my dad bought our first PC, he brought it into the house at night so the neighbours wouldn't see it. It was quite expensive considering our budget, and inspite I enjoyed it a lot, it wasn't until 1994 that I finally gave a rest to all those memories of myself playing with my Commodore. That was because the Commodore 64 had so good graphics and sounds, that I always missed them, and since in 1994 I got my first multimedia kit, I finally overpassed it.
A month ago I bought a C64, a datassette, and 1571 disk drive. I also received a TI 99/4A as a gift and I still have my MSX.. maybe someday I'll build a museum in my basement, if I ever have a basement.
