70 MB Internal Hard Drive  (250-4067)     Features     Faxback Doc. # 5076

The 70-megabyte hard disk drive is an internal fixed-disk storage device 
for all computers in the Tandy 3000/4000 series.  This hard disk drive 
significantly increases the storage capacity of your computer, and yet it 
requires no more space than any other half-height drive.

All computers in the Tandy 3000/4000 series support up to two hard disk 
drives.  However, to support a hard disk drive, your system must include a 
hard disk controller board: either Cat No. 250-4060 (for both hard and 
floppy control) or Cat. No. 250-4058 (for hard disk control only).  You 
should install the 70-megabyte hard disk drive and any other internal disk 
drive(s) before you install the hard disk controller board.

Note:  If your computer contains an early version of the 250-4060 controller 
board (Serial No. WD1002-WA2), it will not allow you to use all the storage 
space on your 70-megabyte drive.  Replace the old 250-4060 for a new 
250-4060 (Serial No. 1002WA3).
