- My point precisely! Program one is actually writing the file that progran

- And how do you propose to do that? (Assuming avid listener mode here)

-
- Sure I do, but geez, can't we point out its warts now and then? I mean it
- does have some you know.

-
- The cpu's are the originally installed MC68B09EP, and the Hitachi
- HD63B09EP, a considerably smarter chip. Furinstance 32bit/16bits is 37
- clocks worst case for the Hitachi version.
-
- Radio Shack sold the last version then, with 128k of dram, and called it
- the TRS-80 Color Computer 3. The Shack sold but as basicly aftermarket
- operating system for it was then called OS9 Level Two. Between the Hitachi
- cpu, and mods to the OS9 opsys to make use of the Hitachi cpu, its now
- about 3x faster than then, without fiddling with the system clock. My
- machine currently has 2 megs of dram in it, drives 2 monitors
- simultainiously. The cpu is slow, at 1.79 mhz due to the video driver chips
- being interlocked to it and stuck at NTSC standards for video. But I can
- move stuffs with zmodem at 600+ cps anytime, and thats faster than my net
- account can (usually) on this Amiga. So speed is relative I guess.
-
- It really is a ghost from Motorola's past that just can't seem to be shooed
- away. Rather like the old TI 99/4a which I don't use anymore, but there is
- still active developement being done on it (the 99/4a) the last time I
- checked. The "Nitros9" operating system for the CoCo is still under
- developement as we type, and I've had a very small part in that project
- myself!
