The Termination Power modification for Apple SCSI cards consists of adding
a diode. The mod for each card is shown in resource file R009SCSIMOD.GIF.
The High-Speed card pic shows a simple sketch of the back of the Apple High
Speed SCSI card near connectors 26-33. The directions say that you connect a
1N914 diode between two points:
The anode (non-banded end) of the diode goes to the *top* of L1. The cathode
(banded/striped end) of the diode goes to the >bottom< of RP2
The pic shows the *top* of L1 to be a solder pad (just a solder pad with no
trace showing) a little ways up from a point between connectors 32 and 33.
The >bottom< of RP2 is just a bit up and to the left of the *top* of L1. It is
the lowest of several points (the pic shows 8) arranged in a vertical column and
should have a trace going off to the left.
The other pic shows where to connect the diode on an Apple Rev C SCSI card.

019- Can I get a Focus drive bigger than a couple hundred
MB?
Get a 40MB Focus Hard Card from Alltech. Get an 800MB IDE 2.5" Quantum GO-
drive from Computer Shopper sources for pennies. Replace the original drive on
the Focus Hard Card with the big one (VERY easy and self-explanatory, just use a
screw driver). Low level format, partition, and high level format. That's it!

020- On my ROM-03 GS the hard disk is connected to a CMS
SCSI card. How do I install System 6.0.1?
It turns out that the SCSI drivers that come on the Sys 6.0.1 Install Disk
downloaded from ftp.apple.com are incompatible with CMS ver 3.0 (and probably
earlier) SCSI cards.
What I did was to replace scsi.manager and scsihd.driver in the System
6.0.1 Install disk SYSTEM/DRIVERS folder with scsi.manager, scsihd.driver, AND
CMS.driver from the CMS Utility disk.
With the replacement scsi drivers installed, the Install disk recognizes
the hard drive and installation went smoothly from that point. (The CMS files
are dated 1989 and 1990, so they are a bit older than the 6.01 files, which are
dated 1993. But, they work!)
