The first culprit I'd look at is /dd/cmds/shell on your custom diskette. Did you leave things out of it to try to use less RAM? The reason they added all those other commands to the file is that the shell is barely 1K long, so a tad less than 7K would be wasted if all that was in /dd/cmds/shell was just the shell. >If anybody out there has had there COCO3 upgraded, and I'm sure you >ALL did, can you tell me where you got it done?

Radio Shack's prices for the 512K upgrade may have improved since the last time I looked--the 1989 catalog, I think, came out in the midst of the gov't-induced RAM shortage, and had a pretty outrageous price. I got a Disto 512K upgrade some time ago (lucked out and did it before the RAM shortage), and if you get any upgrade with the RAM already installed, then it's trivial to install it yourself. I'm hardwarily incompetent, and it was no problem for me, so anybody should be able to do it. :-) >After I get my COCO3 upgraded, you can be sure to see some good >BASIC09 source code posted here.

Be sure to get on the BITNET CoCo mailing list and check out some of the files available from its file server, most notably various patches that speed up and correct some pesky bugs in WindInt, and Kent Meyers's patches to MultiVue if you plan to use that environment.
