Problem is, when I open up the codeplug in a hex editor (wxHedEditor), offset 0x70 is E5, not 80, as specified. The next offset, 0x71 however, is 80. It definitely is a JT, as putting a diode across the accessory terminals brings up the "CHAN" softkey. Anyone run into this before? Perhaps I'm doing something wrong. I do feel pretty confident though, certainly required a bit of remembering to get an old machine together, and get DOS going again. Below is a screenshot of the current codeplug, the field with the box around it is offset 0x70.
Thanks in advanced,
Trevor
