TBACK

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.
