[net.micro.att] Hard Disk upgrade for PC 6300

ruth@houxa.UUCP (R.LEWART) (05/08/85)

I'm planning to buy a PC 6300 with a single floppy, then add
a 20 MB internal hard disk.  Any special requirements for the
disk controller?  Any problem with the existing power supply?

I would appreciate any suggestions.  Thank you, Ruth Lewart.

First see if they directly support the higher speed clock that is
provided in addition to (very important!) the 4 Mhz clock used for
IBM compatable cards. Using AT&T's 16 bit i/o format.

Second try to consider using a half height hard disk and a tape backup
in an separate cabinet, with it own power supply. This will allow
frequent backups and also provide you with the ability to leave the hard
disk powered up all the time.

Track to track access is important, as is a disk buffer for the hard disk.


Thats all I can think of now.....
