RL01/02 DRIVE TEST 2 (SEEK)
ABSTRACT :
This program is part 2 of 2. The test starts detecting outer and inner guard
band. Seek operations undergo a broad range of testing using single
differences, proceeding to seeks of greater differences. This test does not write
onto the disk, you can put it into the "WRITE- PROTECT" mode.
OPERATING PROCEDURES :
.R ZRLJB2

This program is running under the supervisory program.
This supervisory program will first talk to you.
CZRLJ-B-0
CZRLJ TESTS OUTER & INNER GUARD BAND DETECTION AND SEEK
OPERATIONS
UNIT IS RL01,RL02
RESTART ADDRESS 145702
DR>START <CR>

You have to answer the hardware questions.
This is a (mostly used) example :
Change HW (L) ? Y<CR>
# UNITS (D) ? 1<CR>
UNIT 0<CR>
RL11 (L) Y ?<CR>
BUS ADDRESS (O) 174400 ? <CR>
VECTOR (O) 160 ? <CR>
DRIVE (O) 0 ? 1<CR>
DRIVE TYPE = RL01 (L) Y ? N
BR LEVEL (O) 5 ? <CR>
Change SW (L) ? N<CR>

It will type (if no errors)
CZRLJ EOP 1
0 TOTAL ERRS

If you answer Y to the question :
CHANGE SW (L) ? Y <CR>

you can change the following parameters:
USE ALL CYL (L) N ?
USE ALL SECT (L) N ?
LOW SEEK LIMIT (L) N ?
UPPER SEEK LIMIT (L) N ?
USE ONLY ONE SURF (L) N ?
INPUT ERROR LIMIT (D) 20 ?
DATA CMP ERR LMT (D) 10 ?
