trs-80 model II trouble--problem solved..and follow-up

Subject: RE: trs-80 model II trouble--problem solved..and follow-up Date: Wed, 16 Dec 2009 08:10:24 -0600 From: bbrown at harpercollege.edu To: cctalk at classiccmp.org Thanks to everyone's advice. You were all right (as was my original suspicion)...that it was the video memory. Thanks to the pointers on where the video memory was (I don't have schematics or other tech info on this system). I was able to find the bad memory...and, amazingly, I found that I had another 2114 that I could put in (I took it out of my heathkit microprocessor-trainer. And it makes the trs-80 work much betta! So...a couple of questions: 1) How can I get just 1 2114 that works to replace the one I took out of my heathkit? (the place that people pointed-out for buying chips has a $25 minimum..and I don't need that many chips). 2) What can I do with a model II now? When it is booted into CP/M, will it only run CPM stuff specifically for the trs-80 or will it run any CP/M stuff that is on 8" floppy? 3) Where can I get some disks with interesting goodies to run on the model II? (most of the disks that I have with it have some office software and backups of some data...not too much of interest). Thanks! -Bob
