I am sure you can guess, I get a lot of spam. The only way to make sure I get your email is to use "TRS-80" somewhere in the subject line. Subject lines like "Please help" will automatically get swept away, and you will never get a response.

One quick note: I have no knowledge or experience regarding the CoCo line, the Notebook line (Model 100/200/600), or the Pocket Line. I cannot answer questions about them.
