These are custom made chips and can't be found for much less than that. PG Design also makes a board that fits inside the model 100 that lets one bank in two extra 32K modules make a total of 96K for the machine. They also have a copy, rename, and kill routine for the main menu. >2) What are good sources of information for >hardware/software options and ideas available >for the TRS-100?? A great book on the subject of hardware and software for the model 100 is Hidden Powers of the TRS-80 Model 100 by the WAITE Group. The author was Christopher L.

If you like to program in BASIC (Yeecch :->) it has some nice features. You can capture interrupts (kind of) from the keyboard and com port to make I/O easier. I am a diabetic and have to monitor my blood sugars three to four times a day. I use my model 100 to keep records of my blood sugars and make plots on my printer. I can store up to a year of data with my short 3K program and 29K of extra ram. -- ----------------- Michael S.
