Thanks a lot for this info.  I have always known about the cache and when
I use sysinfo it says data cache off so I put a command in my SS to turn
it on thinking I was missing something.  I guess I'll turn it off.  Since
you are answering questions can you tell me what mungwall and enforcer
are? I know people mention using it on a 3000 cause it needs an MMU. 
Thanks for being helpful!  One other thing, I use an A3000 with 2.04 in
rom, is there anyway I can use CPU or some other command to softkick 1.3
in rom? (I know I could do it w/o the rom but I just want to go 1.3 in
rare times not enough to justify removing the rom.)  Thanks!

I use a Microtouch (also without docs) that was bought by another company (who 
cannot locate the docs for it).

The two progs that were with it are GPTouch (the driver) and ??GPPrefs?? (the 
configurer).

It can be configured to run with finger dragging, single touch or another mode 
which escapes me at the moment.
 
If anyone can help with docs, I'd love to hear from you...

A problem I have at the moment is the sampling rate.  The finger drag runs very 
slowly with various apps due to the large number of small-increment mouse movements
the driver appears to be simulating.  I've played with the "sensitivity" 
control but this not appear to make much difference.

This is only on a badly designed system where cache management of such is not
done in hardware.  The CSA MMR DOES properly do this, so the data cache is
not a problem in this respect, and should be used, and can be used when
desired.  The only setup I am aware of which had the problem of inproper cache
managment of cacheable address spaces is the older Ronin Hurricane accelerators
(the 68030 versions).

Given the price/performance ratio, this should make the Golden Gate II
quite marketable. Have any of the current users indicated whether they have
written any code to use a VGA card in a frame buffer capacity?

Also, is it possible to use the GGII/VGA combination of hardware on the Amiga
side and still have access to the VGA card with a Bridgeboard installed
(not at the same time of course)?

THanks to all who responded to my comments and queries regarding
Adaptec controllers and the SupraDrive 500XP.

Solution:  I had a defective DB25<-->Cent.50 cable.  One of the
           data lines missed connection in the DB25 end.

I should've known better than to trust a $3.95 cable.  Oh well.
I'll just run out to my local CompUSA and get a real MAC
cable  (maybe I'll actually get some quality control.)

I'd make teh cable myself, but the MAC cable will be cheaper
than the parts alone, I can almost guarantee.

I pulled the cable off of my  Apple //e hard disk and plugged
it betweent the SupraDrive's external connector and the Adaptec'
Header50<-->Cent.50 cable I made adn everything came to life.
formatted without error and mounted beautifully on the next re-boot.

Thanks again  (especially for putting up with a lame-brain like me.)

I heared a rumor that Commodore discontinued the A2000 line.  If this is
true then this may explain the low price of the the A2000 from creative.

Yes.  There are commerical boards that allow you to plug in the 2.0 ROM
chip inside the A1000.  There is also the Amazing Amiga 2.0 ROM mod.
somewhere.  I would be interest in the Amazing PAL equations if someone
would be kind enough to email me.  There are a lot of typos in the
A1000 Tech. manual.

I have just spent the last 3 days putting in the 2.0 ROM into my A1000.
I came up with a design which requires reprogramming 2 PAL chips on the
daughterboard (+ cutting 2 traces) and wiring the ROM socket to the CPU
(39 wires for the ROM).  The machine either runs off 2.0 ROM with
daughterboard disabled or boot off with a 1.X kickstart at the flip of a
switch and power up/down.  I am still trying to figure out the PAL
equations to make kickstart ram appear at C00000 so that it will be
available under 2.0.

The hard part of my hack is removing the PAL chips and having access
to a PAL programmer.  I would not recommend this to everyone.

>I know that you can buy a new motherboard with 2.0 on it, but I want to
>know if there exists a kickstart disk for 2.0?

There is a A3000 super kickstart disk.  Since the daughter board on
the A1000 can only handle 256K, it cannot load any 2.X kickstart ROMs
which are 512K.

That depends on the expansion you'll need.  A500 still have the biggest
3rd party support (A1200 is catching up).  I sticked with the A1000
because I have no $$$$, but then again I can design and build my
peripherals.

'Due to a bug in Commodore's Operating System Kickstart
3.0 (Rev. 39.106) the mousepointer sometimes refuses to
appear on the workbench after using Oktagon's Login screen.
Therefore, the Login Screen option has now been disabled
(factory default setting) as a workaround for the bug. A
newer Betarelease of Kickstart 3.0 has already corrected
this bug. An update is possible by replacing the two Kick-
start ROM's from Commodore'

Note, these are statements made by BSC, _NOT_ by me! It's
in Issue 8 (jan 93) of their 'Inside' flyer. Could anybody
from Commodore please comment on the above statement. Is it
true and is there a fix? If so, how and where do I get this
fix for my (KS 39.106) A4000? And what other problems are
fixed, or being fixed? And I assume the upgrade will of

There MUST be a .17 microfarad capacitor from each of the Pot-X and Pot-Y
pins to ground.    -Thank you Randell Jesup (jesup@cbmvax.commodore.com)-

Happy landing,

Achim
