Verify that the modifications listed below have been installed on the 86100A DCA. After the
modification is complete, a label is placed on the rear panel indicating that the instrument has
had the modification.
Intermittent Front-Panel Keypads
Service Note 86100A-01
Serial Number: US4032 and below
Early production units had keypad assemblies with carbon ink on the printed circuit boards
together with silver contacts on the rubber keypads. Over time resistance builds up on the con-
tacts. Newer keypads have carbon contacts.
The modification involves replacing the rubber keypads on the A7 Front-Panel Assembly.
to “To Replace the A7 Front-Panel Keyboard” on page 7-35
for instructions on keypad replace-
ment.
Refer to “Front Inside Panel Identification” on page 10-12
for the part numbers of the three
keypads.
Intermittent or Slow Floppy Disk Reads
Service Note 86100A-02A
Serial Number: US4106 and below
On early 86100A mainframes, the LS-120 disk drive would occasionally experience difficulty
with read and write operations. A new ground connection was added on the A16 LS-120 Adapter
Board Assembly. If needed, replace the A16 (part number 86100-66505) with the newer assem-
blies as described in
“LS-120 Disc Drive Modification” on page 6-19
.
Optionally you may modify the existing A16 LS-120 Adapter Assembly by adding a ground clip,
Agilent Part number 5021-4312, between pin 2 of the 44 pin connector and the adjacent screw
hole. Solder the ground clip to pin 2 so that the hole aligns with the screw hole. Re-label the
assembly to 86100-66514.
Intermittent Problems with Vertical Calibrations or Vertical
Trace
Service Note 86100A-03
Serial Number: US4032 and below
On early 86100A mainframes, the PLDs on the A13 Acquisition Assembly would occasionally
go into a write mode on power up. This causes various symptoms such as vertical cal failure, ver-
tical trace at top or bottom screen, and loss of control of the vertical trace. Sometimes the DCA
