All diskette drive types (except the high-density drives in the ROBIE and 4X)
are ftmctionally interchangeable between manufacturers.
Because of the number of manufacturers from which Kaypro gets its diskette
drives, no attempt is made in this manual to show alignment procedures fur
each of the drives. If you have access to a drive manual fur a particular
model, and have the Dysan Alignment Diskette (Dysan's part number: 224/2A)
the knowledge, and an oscilloscope, go ahead and align away. Kaypro
Corporation's policy is to do no repairs on these components.
fbwever, since the company recognizes the fact that many customers want a
KAYPRO computer in which roth drives have the same outward appearance, we
provide a guide fur determining models of diskette drives from the placement
of the LED and the drive door closure.
This section also contains diagrams and instructions on jumpering the various
models of diskette drives to be used as either A or B (or, in the case of the
KAYPRO 10, C) drive.
DISK OOIVE crEANING
Generally speaking the majority of people clean disk drives too often. Unless
the environment is eSPecially dusty or dirty, under commercial use there is no
reason to clean the drives more than twice ayear.
Use care in selecting a cleaning kit. Many of the drive head cleaning kits on
the market are very abrasive. Cleaning is done by the liquid solution, not by
mechanical scrubbing.
***N0l'E*** The manufacturer (Drivetec) of the high-density drives in the
ROBIE, and 4X recommends only fuur brands of head-eleaning kits fur their
drives. The letter from Drivetec states:
"THE FOLLCWING CLEANING DISKS HAVE BEEN EVAUJATED
AND ARE RECCMMENDED FCR USAGE CN THE DRIVEI'EC DISK
DRIVE WHEN HEAD CLEANING IS DEEMED NECESSARY:
1) SCOIQ-I #7 440
2) HEAD CCMPUI'ER PRCDUCI'S 5 1/4 CLEANING DISK
3) piRFEcr DATA 5 1/4 CLEANING DISK
4) FLOPPICLlliE 5 1/4 CLEANING DISK"
