I think I did that a few months ago, actually. It was admirably speedy, as I recall. It was pretty much identical to the GW-BASIC version I did for my Omnibook and palmtops. I need to build a cassette cable for my 102 (and CoCo 2), but it seems like the Radio Shacks around here have stopped carrying 5-pin DIN connectors.

EDIT: Here's my GW-BASIC version if you're curious. I can't remember if the timer stuff is the same on the 102's version of BASIC, but it's extremely similar to GW-BASIC. Other than that, it would probably run as-is. Maybe I'll have to pop some batteries into it this weekend and race it against my 200LX.

Thanks for that link, Dave, I just printed the program. I'll implement that on my 102 after school today. Bill/Smithville NJ graciously gave me a 102 he acquired at a yard sale. My students say it looks "old" and I replied "it IS old!". I always wanted to get one of these, it is a very nice platform for BASIC programs, and I REALLY like the fact you don't have to wait 5 minutes after turning it on to do something productive, like you-know-what-OS (apologies to Bill Gates, who helped write the BASIC on the 102).

I'm living in the past with my Tandy 102, HP-65, BASIC programming, Wonder Years DVDs, and Pulsar watch! And lovin it!
