More on Q-Save in the 1500

Since my last tip on using QSAVE with the Timex 1500 (see Updates vol. 1, #4), it seems I may not be the only one out here with such a set-up. If that is the case, others might be interested in modifying the QSAVE program so as to allow its use with the 1500 and the Timex 16K memory expansion.

This modification involves moving the QSAVE machine code to the top of the 32K available memory and then changing the call and jump commands to the new addresses. As there are 50 calls to be modified, it is easier to change all instructions that contain the bytes that have to be changed, and then change the three occurances that aren’t addresses back to what they were originally.
