TRS-80 Pocket Computer questions....

I am wondering if anyone knows of a good source of Radio Shack TRS-80 Pocket Computer information. I just picked up a Pocket Computer (presumably the 'model 1', as it doesn't say Pocket Computer II, etc.). It is catalog 26-3501. Anyway, it came complete with the Printer/Cassette Interface unit.... which you snap the computer into, and the 'expansion unit' has cassette interface plugs, as well as a small calculator-like printer. Pretty snazzy little unit. Looks like it has never been used, and works like a charm. Also, I got the little guy for free!! Here's my question: It starts up to BASIC. And there are several modes of operation.... DEF, RUN, PRO, RESERVE. With a little tinkering, I have managed to figure out that the PRO mode is to program in BASIC programs. And, the RUN mode is to run them, etc. I am curious for full information on these modes. I also am wondering how to access the printer. Say, listing a BASIC program to it, or printing messages, etc., to the printer. On first guess, I figured it might use the LLIST and LPRINT type commands such as other early TRS-80 BASICs did (back in my days of adventure game making :-) .... but, I have been unable to get them to work. It seems whenever I enter those commands (or other incorrect commands), I get a 1................................ up on the screen, this seems to be some type of syntax error. I guess I just don't know much about this part of the TRS-80 timeline and am looking for any help. Accessing the printer, error codes, mode explainations, cassette commands in BASIC, etc. Thank you, CORD COSLOR -- ____________________________________________________________ | Cord G.
