This situation is a little different from adding a disk to a PC, since I already have a disk controller (the one that came with the XT) and a 130 watt power supply. I also have my front panel full, but would like to try to keep all the stuff in one box if practical. Also, I have no free long slots in the box. Possibility 1 - Replace the floppy drive with a 1/2 height floppy and a 1/2 height 10MB disk. This looks like it should work, except for a few nits. Are there standard sources for mounting hardware for 1/2 height drives in an XT? How about for getting the extra power connector I need, probably by plugging a Y-connector into one of the existing power cords. Possibility 2 - Replace the 10MB drive with a 20MB drive. Detailed staring at the XT technical reference suggests that the BIOS should be able to handle a 20MB drive if two switches that I can't find are set appropriately. Anybody do this? If so, do DOS and utilities work right? I use DOS 3.0 which handles the AT's 20MB disk, so there may be some hope. Possibility 2A - Same as 2 but replace the IBM disk controller. I'd prefer not to, since a disk controller costs money. Remember that I don't have room for both the IBM controller and another one. Other suggestions are welcome.
