I seem to have an ATT 6300 pc that runs DOS. It was put in my
possession for repair without manuals, etc. Since I've never
seen one, I'm a little lost.
There is a main cabinet and an expansion box. The main cabinet has the
mother board, power supply, a video card, a space where the hard disk
fits, and one other card with a 25 pin port (female). I assume that
the card is for a printer. The box also has a wide ribbon cable that
leads from under a false bottom to the expansion cabinet.
The expansion cabinet has a power supply, a circuit board that I assume
controls 5 power switches on the front, and a floppy disk drive. The
ribbon cable has two connectors on it (daisy-chained). The end connector
attaches to a floppy disk drive, while the other hangs loose.
The problem lies in the two hard disks that are as yet unattached.
From what I can gather, the owner had the 10-meg attached and wanted to
upgrade to the 40-meg. Now, I would assume that there should be a
hard-disk controller card in the main cabinet for these disks. There
is not, unless the first connector on the ribbon cable is supposed to
connect it to a controller under the "false" bottom. Also, there is
no thin ribbon cable, which is usually typical for hard disks.
My questions are this:
1. What's the first connector on the ribbon cable for?
(a second floppy drive? 10-meg hard drive?) Or is
the floppy drive connected to the wrong connector?
2. Is there some kind of hard disk controller under the
"false" bottom? As I mentioned, the 10-meg was installed
at one point. Am I missing some of the parts? (ie. a
hard disk controller and cable)
3. What is needed for the 40-meg disk? I assume a controller
card needs to be purchased. Does a 6300 need special
parts or will IBM clone parts work?
Please e-mail responses.
Thanks
Tom
