030- I have a ZipGS. Sometimes my GS 'hangs' on power-up. Why?
031- The speedup has led to system crashes. What's the problem?
032- A new accelerator board has led to crashes. What's the problem?
033- How can I get a display of IIgs speed?

001- What are the correct settings for a ZipGSx? I've
tinkered with "CPS Follow", "Counter Delay", and the like
but have no idea what I'm actually doing.
Bank C/D Cache Enable-- Leave this at the default setting (SW1-1 set to ON).
This tells the Zip if it's OK to cache bank-switched RAM (the old language
card area). Zip's own docs say "there is no known software requiring this";
but, that is why it's there, in case somebody ever finds software that doesn't
like it you can try setting it the other way.
Correct "Misc Settings" CDA panel display*: C/D Cache Disable Off
Defeat Paddle Delay-- The delay is necessary for playing most 8-bit games
which use paddles or a joystick. Recommended setting is to have the delay
active (SW1-2 set to OFF) unless you feel like experimenting.
Correct "Misc Settings" CDA panel display: Joystick Delay On
Defeat AppleTalk Delay should always be enabled (SW1-3 set to ON). The
desktop will run much slower with the delay active. The reason most people
needed it was for AppleTalk under System 5, and now there is an init on tybalt
that fixes that. System 6 fixed the problem but requires CPS Follow to be
enabled for the fix to work.
Correct "Misc Settings" CDA panel display: AppleTalk Delay Off
Defeat Counter Delay is present so that the ZipGS can be set to avoid the
delays needed to pass one of the IIgs diagnostic self-tests. When set OFF, the
ZipGS will "deaccelerate" (it temporarily ignores that any data can be read
from the cache instead of the motherboard) for about 5 milliseconds any time
you read one of the Video Counters. The delay lets the IIgs get past the
particular self-test. Otherwise, the recommended setting is SW1-4 set
to ON (delay inactive).
Recommended Correct CDA "Misc Settings" panel display: Counter Delay Off
Defeat CPS Follow should always be disabled (SW1-5 set to OFF). This lets
the ZipGS automatically 'follow' the IIgs-- e.g. when it switches to "Normal"
speeds the ZipGS is disabled. This is a requirement for a reasonable amount of
timing-critical software. If CPS Follow is not active you will have problems
with Disk ]['s and System 6's AppleTalk driver and anything else that expects
the Zip to slow down to 1MHz when the IIgs is instructed to slow down to 1MHz.
For instance, border text demos (like the FTA XMAS demo) won't work. Expect
weird things to happen if you play with this one.
Correct CDA "Misc Settings" panel display: CPS Follow On
ZipGS Enable-- The card should normally be enabled (SW1-6 set to ON).
SW1-7 and SW1-8 should be set to correspond to the size of your ZipGS's
cache memory. (see below)
