TRS-80 Emulator (I,III,IV) for X Windows

README.tpm Tim Mann <mann@pa.dec.com> 1/12/98

As computer scientists, we always long for something bigger and better than what we have now. Give us a megabyte, and we want a gigabyte. Give us an emulated TRS-80 Model I with Level II BASIC and cassette, and we long for the Expansion Interface and floppy disk drives. Give us that, and we want a Model III. Give us a Model III, and we want a Model 4!

This is a snapshot of the work I've been doing on xtrs to add these niceties. My main additions over xtrs-1.0 have been floppy disk and hard disk emulation, timer interrupt emulation, a kludge to import and export data to the host system, Model III mode, Model 4 mode, a rewrite of the keyboard handling, support for most of the undocumented Z-80 instructions, and a bunch of bug fixes and minor improvements.

This project has been a real (48KB?) trip down memory lane for me. I worked as a programmer for Logical Systems, the company that produced LDOS, during 1980-81 before I went to grad school. I no longer own a TRS-80, but I recently found a box in my storage closet containing all my Model I hardware manuals, schematics, ROM disassemblies, and even the assembly listing for a version of the LDOS Percom Doubler driver that I helped write, giving me enough information to get my additions to xtrs off the ground.

Since then I've done much more. Check out my TRS-80 Web page at http://www.research.digital.com/SRC/personal/Tim_Mann/trs80.html for details!
