I have just added a TI expansion unit to my collection. It came with all the proper internal modules, but there's a possibility that the Disk Management plug-in cartridge (firmware) is missing. If the person I bought it from is unable to find it, is there any workaround to not having this? Does anyone have a spare one to sell? I'm reasonably new to the TI system, so any advice or input would be greatly appreciated! Also needed: The "A" and "B" diskettes that accompanied the Editor/Assembler package. I do have the firmware cartridge and docs for this. Steve --
