I made the mistake of telling some work colleagues that I was interested in old computers, and one of them bought me a 1987 Toshiba T1000 that they saw in a junk shop (the one with the ROM hard drive, 512kB of RAM and 720kB floppy drive).
It doesn't work, of course. I received it with all the screws missing from the case, and someone had half-inched the battery pack, so I suspect it may have been stripped for parts.
Without the battery pack, it won't start up, at all. The power LED doesn't even come on. The battery's supposed to be a quartet of 1.2V nicads, producing 4.8V. I actually *have* some (pulled from my T3100SX), so I might try to bodge something up; the problem is that the battery connector has four pins, and there's no indication of what they do.
The maintenance manual says that the voltage between pins 1&2 and pins 3&4 should be about 5V. This implies that pins 1 & 2 and pins 3 & 4 should be shorted together. Right now, with the 9V power supply connected, I'm seeing voltages ranging from about 4V to 9V across various pins, so that makes me kinda uncomfortable. Is shorting them together reasonable?
Additionally, I'd rather like to run the thing without batteries entirely, purely off the mains; any ideas?
