Tandy Model I Problems

Well, today I decided to repair the power supply on the Percom floppy that I have for my pair of Model I's. Then, I decided to see if a complete keyboard-EI-floppy setup worked. Therein lies the problem... It seems like each CPU (a 4k and a 16k Level II) won't recognize either EI (a Rev 0 and Rev 1). Both EI's have 32k of RAM. All that I get on the screen is garbage. I'm turing the EI on first, then the CPU. I've also tried two types of EI cables, one buffered and one not. I can tell which cable goes to which EI because the floppy drive will initialize only with the right combo. It sounds like I have two bad EI's, but the thing that throws me is that the floppy interface performs a floppy reset. Does anyone have any clue?? Also, how does one refer to the floppy drive in a BASIC statement? For example, if I want to load a program, do I type LOAD "0:test.bas"? I have no manuals for these machines, and it's been a loooong time since I used one of these. Also, on an unrelated note, the Altair scans are in, but I'm waiting for Bill Whitson's address so that I can Fedex a tape to him. Does anyone have it?? Rich Cini/WUGNET <rcini(a)msn.com>
