I've been told that the other pair of sockets are for eproms because they have
different pinouts.  My A3000 is the latest revision and has 2.04 roms in the
front pair of sockets.  I have read an article on installing an 040 board and
the early release (read eprom) roms that came with it had to be installed into
the rear sockets.  The UNIX machines come with boot code on disk that is run 
under AmigaDOS.

The 'Boot Roms' that were originally in the machine are 2.01 (from memory).  
You can get them to boot up workbench by clicking on the hidden close gadget
somewhere up the top left of the rom boot menu.

All A3000 owners note: 
Also, you may have some problems with games when using 2.04 roms instead of
boot roms and a kickfile.  The symptoms include scrembled graphics, very slow
screen updates etc.  This is caused by the games code writing off into space
randomly (crappy code) and hitting fat busters bus timeout (intended for slow
zorro cards).  Fat Buster has a 200ms (I think) timeout for the access, before
signalling a buss error to the cpu.  This is why some games mess up.  It is 
better with boot roms, because the map out much of the memory map with the mmu
thus terminating the access before it hits the external buss (and the timeout).

As an example of this, Alien Breed runs fine on a friends 3000 with boot roms,
but screws up with mine with 2.04 roms.  Agony messes up on both machines, 
because the boot roms map some of the reserved areas as transperent.

I am currently making an A3000 compatible version of SetCPU to fix this up,
and to perform a number of other useful things like disabling fast ram, cache
inhibit on reboot etc.  When it is finished, I will make it available  (with
Dave Haynies permission).  Currently there are only 2 games I cannot get to
work properly.

	Never mind!  I just called NEC tech support and was told that
"5 millimeters or less" is an "acceptable" amount of tilt according to
their internal standards.  To me, it looks plain silly, but the tech
support guy said that "any" monitor displays "some" tilt when you use
full overscan, and that NEC's standards are "more strict than most other
manufacturers'."

	So I got the answer, but it isn't the answer I wanted to hear.
There's really no way to fix the tilt.  Sigh.

	Also, I should have known that the Amiga was not at fault because it
had a motherboard swap several months ago (for a different reason), but the
tilt problem remained.

is there one out there to add memory outside the machine by using

I measured these numbers with AIBB V4.5, SysInfo 2.73, and other

I recently bought a CSA-MMR '030/'882/MMU from Memory World (Bensalem,
PA). They stuck a 33MHz crystal on what I believe was a 20MHz CPU and
said it would probably be alright, but if I saw problems I should
switch to a 28MHz crystal. Has anyone else tried to couple the FPU and
CPU of a 20MHz 68030 to a 33MHz crystal and is there any reason I
should beware of this combination. I haven't experienced any problems
I can say with certaintity are related to this setup, but a friend
warned me that the fast crystal could (and probably would) burn out my
CPU. Any opinions/suggestions? Email appreciated.

somewhere along the line the machine just hangs... Once it even got so
far as to load workbench and then crashed before finishing the rest of
my startup-sequence... :( Any suggestions? (according to the sticker

i can conditionally recommend AMT International in california - 
1 408 942-9655 and FAX 1 408 942-5509.

their current price for 80ns Static Column ZIPs is $14 per chip, better than
i've ever seen anywhere else.

the "conditionally" part concerns their shipping department, which borders 
incompetent. my salesperson, Sharad, was unfailingly polite, helpful, and
cooperative, but with that shipping department, you'd have to be! the first
time i boughts static column zips from them, two years ago, i was sent 
page mode zips. no problem sending them back and getting them replaced, but
it was annoying to say the least.

two weeks ago, i ordered another eight static column zips. again, i was 
shipped page mode zips. talked to sharad, he sent replacements. the
replacements were page mode again, but in DIP form-factor!   #(*&@!!!
talked to sharad again, he went to the shipping department and
packed the order himself. the chips are installed, the wrong chips sent
back, but what a headache!

so if you order static column zips, ask them to double check the order
before shipping...

	The "Virtuality" system, made by W Industries is based on a 25MHz A3000.
As has been mentioned, it has two graphic cards, one for each eye. The multiplayer
thingy works over a standard thin ethernet. Each A3000 has 4Mb of RAM. The
system is designed so you dont need a keyboard, if you have some other method
of informing the system when someone has paid their money. To change games, you
bung in a floppy which modifies the startup-sequence on the hard drive to 
run game nm (For NIGHTMARE, for DACTYL NIGHTMARE) or game legend (LEGEND QUEST)
You then reboot. If you want more info mail me.

Ok, a technical question for you all.....

I just got a used Supra 2400. A friend of mine has the Supra 14.4K and will
be getting a new set of ROMs when they become available. What we were wondering
was is it possible to put the old 14.4K ROMs into the 2400 and get higher
speeds out of it??? It okwouldn't seem possible to me since the rest of the
architecture was designed around 2400 baud, and there will be no data compression
hardware available. Can this be done????

Start hacking it up guys.......

With the deskjet, you just stick the cartrige in and hit the
"prime" button which takes care of all the "shaking" automatically.

I'll have to check the manual on this but I know for a fact that
with graphics, it is the computer, not the printer that is
holding things up (usually).  (I have an plain 68000)


>>               5) The quality of output from each of these printers.

The DeskJet is great at 300dpi but it is pretty picky about
paper.  You have to find some with a good smooth surface or else
you will end up with furry letters as the fibers wick the ink
away from where it was intended.

I have one of those zorro II boards without any autoconfig logic.  But
I remember seeing someone post (from outside the US -- Europe or
Australia) that said they had prototyping boards WITH autoconfig logic
(that caught my eye) -- maybe they hardwired it to be the hacker's ID
or something.

I think that burning PALs would be a problem for me and I would not
like to have to convert it into logic gates (which may take up the
whole board and leave no space for the A/D stuff -- I haven't looked
at the equations).

Hi,
I have an AS3000 with a NEC 4FG monitor here and I have absolutely no border
at all, this is because the monitor has some electronics that lets you stretch the
immage on the screen to a certain extend. This is enough fo the Amiga not to have
the black border, but under mac emulation I still get a tiny bit of border on the
right and left side of the finder.
I hope that makes your decision a bit easier.

Arthur.
