Nah, pete,
I'm using a Tandy CoCoIII.
1.7 Mhz, 8 bit bus. 512 k RAM. And a dual floppy drive too!! We're talkin' power, baby.
Gigahertz, shmigahertz. These new machines got nothin' on the old Motorola 6809E.
All kidding aside, I do have one of those, and it's fun to fire it up now and then to see if it still runs.
Back in the day, I wrote a lot of programs in BASIC and machine code.
I had one that did fractals. It would run for about two days to do one screen. Today's machines can do the same thing in a matter of seconds.
