All, I'm trying to track down the source of odd behavior in my 102. It's had a long history of memory problems that I thought I had resolved by replacing the decoder IC. Some time after that, it developed an issue where trying to load CO exes via basic loaders would cold-start the system and it would boot reporting only 8k installed.
Greg suggested a bad solder joint, so I reflowed all the RAM and decoder joints on the board. THis has changed the behavior a bit. This time I was able to load TSD.DO via telcom, but "load"ing it into BASIC cold-started the machine to reporting ~11k free. Also, while soldering the RAMs I noticed what looks to be a very bad bodge on the printer port. These 2 are clearly making contact (verified w/ meter). The top wire goes to a cap to ground, the bottom one runs to a pin on an IC that I didn't bother checking. Are these normal on a 102? https://drive.google.com/file/d/0BwcKlz5N5PLcYnR6XzZPYlpyRDNXNWo2THhPYURpMlQzZWc4/view?usp=sharing Thanks, -Josh
