H/Z-100 Field Service Bulletins

General Notes:

-- The following article appeared as an insert to issue #42, November-December

1995, of the "Z-100 LifeLine".

Z-100 Field Service Bulletins

Some of these bulletins contain out-of-date information, however, I left it in for two

reasons - I don't know for certain if the information still applies, and older machines

and publications are still out there to which the information may still apply - such as

the Z-100 Interim Service and the Service Data Manuals, which seem to be

completely different from the Z-100 Service Manual I received from Paul. Also, while

you may not have some of the manuals mentioned, I thought the information may

still be valuable for your other manuals or notes. Where I have updated information,

I have added it.- ed.

FSB-Z100-001: Disk Drive Specifications

The specifications in both the Service Data Manual and the Z-100 Product Info

Manual stated the disk controller will support up to four 8" drives and four 5.25"

drives. At that time, it was a hardware specification rather than a software

specification. Early software only supported 2 each of the 5.25" and 8" drives.

FSB-Z100-002: Blooming of Display

Some All-In-One computers exhibited "blooming" of the video display for about 20

seconds after turn on. This condition was considered normal.

FSB-Z100-003: Metal Filings in Cabinet

When a Z-100 microcomputer is disassembled, you may notice small metal filings on

the bottom of the cabinet on either side. These filings were from the self tapping

sheet metal screws that were used. Carefully remove any metal filings with a

vacuum cleaner or cloth. This problem has been corrected in later production by

using regular sheet metal screws.
