Yep. but that won't help if you have heat building up inside and thus
making some very valuable (like the 68040) component blow it's top.
Which is what happened to my 'sucking' A4000 last week. :-( She's back
now and now has become a cool 'blowing' babe. In my experience it is
better to have a dirty cool Amiga than a clean hot one...

From my SyQuest 5110 drive manual (Page 2-1):

"The SyQuest SQ5110 Disk Drive is easy to install ...  into any
5.25-inch half-height disk drive housing in your computer."

From my Amiga 4000 manual (Page 3-5):

"The top front drive bay in the A4000 can accommodate a half-height
5.25-inch device such as a ...  removable media drive."

So why is my SyQuest 5110 too long to fit in my Amiga 4000?

I'd REALLY like to know.

I don't suppose someone from Commodore could explain this apparent
warping of reality to me, could they?

 As far as I know their pinning is identical at pins 1-40 and pins 41-44 just
replace that IBM-style drivepower connector. According to A600 schematics 41 &
42 are connected to Vcc (+5V), 43 is ground and 44 is connected to Vcc via 4.7
kOhm resistor.
 P.S. Does anybody know what this block in A600 is as it contains two 28F20's
and 74F139 (U37), is labeled FLASH MEMORY and has text 'FLASH AND U37 IS
OPTIONAL'?

Hi,

	I just bought a new printer that has a built in 48K buffer.  This
is great, except that the friendly Amiga goes off, fills up the buffer, and
then has to wait for awhile before the printer will accept more data (I
think the printer waits until a couple K is free again or something).  This
makes the Amiga unhappy, and it's constantly putting up those silly
"Printer Trouble -- Check Wiring, Paper, etc." requestors.

	So how do I tell the Amiga to wait forever for the printer?

	Thanks...

	My friend works at a construction firm that uses AutoCAD and saves
it's drawings to the network server during the course of the day. Later
that evening they are backed up on a D.A.T. tape and kept on file in case
someone needs an old drawing or a revision needs to be made. Well, today
one of his D.A.T. tapes broke with several important drawings on it. He
went to radio shack and got a tape splicing kit and repaired the tape.
When he went back to retrieve the drawings, the software told him that
there were too many bad sectors, and the tape was unuseable. He was
wondering if there is any way to retrieve ANY of this data or is it
completely lost? There is about one Gig of data on the tape, and only
about a half inch missing, and a foot crinkled. Thank You.

I have a Maxtor XT-2190 drive that I was planning on using with the Adaptec
4070A. Any differences worth noting between this "A" and the Adaptec 4070?

Also, does anyone know where I might find an OMTI 3527 SCSI <-> RLL board.
I have been told that this is a faster board, but I can't find any sources.
I know that these things have been out of production for some time, but was
hoping to find one at a surplus outlet. No luck so far.

Another elusive piece I've been trying to track down is an Emulex MT-02.
This is a SCSI <-> QIC-36 adapter that I hope to use with a Wangtek 5099EG24
tape drive (60MB). BTN tape handler supports the Emulex board and I would be
sooo happy to back up to tapes. Thanks in advance to all responses.

Subject: GVP A530 question
Organization: University of Maryland University College
Date: Thu, 31 Dec 1992 04:07:07 GMT

The GVP A530 expander for the A500 has both a hardware and software
switch to disable the unit and allow the A500 to work in its original
mode.

This is fine for software that needs the 68000, but it also shuts off
access to the hard disk and the RAM in the A530.

Does anyone know of software available (I've already scanned the last
few hundred Fish Disks) to return processing control to the 68000,
but leaving access to the hard disk and the extra RAM intact?

Thanks.

  False.  It will run at least as much software as a A3000.  Games that
break on accelerated machines will obviously break on a A1200.

  I just stuck a Connor 80 Mb 2.5" drive in mine.  I cant see where a 
Maxtor would be any different.

  You can get 256 colors with a 1084.  You cant use the DblNTSC modes
until you get a VGA or multisync monitor.

  I'd recommend it.  Its certainly faster, and the AGA is a nice plus.

>everything work the first time around?

I was one of the beta testers for the Zeus card. I am currently using it with
32MB RAM, 33MHz 68040, 1GB Wren VII, 430MB Seagate fast SCSI-2 drive, 100MB
Quantum, 525MB 1/4" cartridge tape drive, and a 44MB Syquest. In addition, I
have a Toaster, DCTV, Epson scanner, ASquared LIVE, and a 2065 Ethernet card
all hooked up and working very happily with the Zeus. Hard drive transfer
rates are MUCH faster (device dependant) but I never checked access times. I
would expect them to be the same since they are really more dependant on the
HD rather than the interface. All software that is 68040 friendly works fine.
There are still a few programs and utlities that I use that I must disable
the writeback cache mechanism (the most annoying of which are CED and view3.2
since I use them constantly).  Did it all work the first time? Well no, but I
was a beta tester so that is kind of understandable. The main problems I
encountered were with getting all the SCSI devices to talk happily together.
While it did require a ROM change I think the main problem was cold solder
joints on an early piece of hardware.  And as you may have guessed, I was
pretty hard on the board in terms of various drives and peripherals. But if
you buy one today, I think you will find it to be quit trouble free. I used
the Zeus to render my latest 3D animated film which required 4 months of
continuous rendering without the machine going down. It was very stable.

This seems fairly reasonable but I haven't checked lately.

>Can you mix RAM densities in the slots?

I am nearly 100% certain you can but I have not done it. Check with PPS.

Thats what I am running.

Shouldn't be a problem but it will definitely be much slower than the
32bit RAM on the card. I'd sell the SupraRAM and install more SIMMs on
the Zeus.
