AT&T 6300 PC

The ATT 6300 was a nice box for the time. The color monitor was really something (if you had color). It had graphics capability somewhere between CGA and EGA for color and something close to a Hercules card for mono. There is no setup disk or rom bios settings for this machine. Mostly that came about with 286-class pc's. I've not yet seen an XT/PC class box with chip-stored settings. You can probably format the hard disk by loading DEBUG from floppy and entering the command: "G=C800:5" - omit the quotes. This command calls and executes a program on the hard disk controller which will low-level the drive. Make sure you know the geometry of the drive before executing a low-level format as it will prompt you for them. The controller will store your geometry on the first track of the hard disk and pull from there just prior to booting from it. The rom on that hard disk controller also handles the boot process. I think the machine's isa buss is 8 bit. You can graft an 8-bit ide controller onto it if you like. I don't know a thing about any other (proprietary) slots but it sounds like ATT to do something like that. Regards, Jeff -- ----------------------------------------------------------- Jeffrey S.
