Hey friends, I nabbed a lovely clean T200 recently, and after writing a few letters on it, I'm trying to print over parallel to an LPT-equipt typewriter I know to work. Using the t200 built in page formatter (shift-print) in a doc, it has the following behavior:
No errors, and LPT typewriter begins printing the first line in the doc, a short date string, and then immediately follows with the rest of a random line, then prints the final line and ends. The same doc prints perfectly when moved to my only other T200 using a TPDD backpack. No obvious corrosion on the connector, did full resets and swapped to a known good Rex. Feels like either bad ram, or maybe a connector problem with a bad clock line or ground or something? Any ideas? Fairly certain it is hardware someplace, but so far it's the only issue I can find on the machine. Was also going to test the ram, but was wondering how folks load testram without loading TS-DOS, and thus changing the MAXRAM and preventing the ramtst from running. Probably a noob question, but curious the easiest approach to ramtest a fresh machine using a TPDD device to load software. Or maybe there's a diagnostic ROM image folks like? Thanks as always
