Overview

TBACK is a program for 32-bit Windows which will rapidly back up the "state" (RAM contents) of your Model 100 or Tandy 102 to a PC.

Experimental Release

TBACK is currently in an experimental stage, but it does work.

Download the zipped executable Here.

Usage

  • On the Model 100, enter BASIC and type:
    RUN"COM:98N1E
  • Hit the ENTER key.
  • From the directory you unpacked TBACK.EXE on the laptop type:
    tback com1
  • Wait about 9 seconds and you should have a file
    BACKUP.CB
    in your directory.

TBACK supports several options. Not all work in this experimental version. To investigate them, type:
tback --help and hit enter.

Suggested Applications

  • Clone your laptop state wholesale and pop it open in VirtualT
  • Offload RAM state after a cold start
  • Quick backups

Future Improvements

  • Add a "recover" feature to load the saved image back onto M10x
  • Offer "quick mode" where unused RAM (free space) is not transferred to the PC
  • Add a extraction feature that can extract any files (DO, BA, CO, ...) in the captured data as files on the PC file system.
  • Although a proper serial port and cable is highly reliable, it would be nice to have a checksum feature.

Design Notes

The background concepts for this utility are described in this article.
