There are theortical limits and practical limits.  The theoretical
limit of a disk drive is 2^32 - 1 blocks.  I belive this is the
physical device size, not partition size.  Of course, a device this
size would have a bitmap of about 262144 blocks in size.... and 
would require 128 MBs of memory to allow the system to work on it...
Of course with the 68030 & 68040 having 32 bit addressing, this would
not be impossible...  Practical, I doubt it..

I'm almost ready to agree with you that it is a piece of junk.  I posted
a while ago about having problems at 14.4k but I just upgraded to 2.04
and I have to see if it helped.  I also have a Practical Peripherals v32bis
FAX send/rcv modem that seems much nicer and much more reliable than the
Supra.  It costs $100 more but it WORKS and has LIFETIME WARRANTY.
I may be getting rid of the one that works the worst.  So far it looks like
the Supra is the loser.

No, the 68040 doesn't have the coprocessor interface necessary for the
external FPU (6888[12]). According to Motorola, the '040 can calculate
the transcendental functions in software as fast as the 68881 does
them in microcode, but they don't account for the time taken by
an 'unimplemented instruction' trap.

Hello out there,

last time I screwed my A2000 rev. 4.1 apart, I noticed a connector (CN 304)
which sits right next to the external serial port. There was a posting in
c.s.a.h not long ago which stated that this is "the internal serial port" of
the A2000. I mailed the guy who wrote the article, but he was of no help.

My questions:	- is this port usable in terms of hardware (pins connected
		  to serial chip)?
		- if it is indeed usable, what's it's pinout?
		- is it supported by serial.device?

Any answers are appreciated as I'm in need of a cheap additional serial port.
Please email your answers, I'll post a summary if there's anything of
interest.

Have a nice day,
			Hanno

P.S.: No, I ~don't~ have any schematics for my Amiga. C= didn't supply them.

have an exact step-by-step procedure for this?  I'm no techie.  :-)

I have come to agree with the position C= has taken.  I am just as
curious about the new stuff as any other amigaphile, however, I think
that there are good reasons for not announcing a product until it is
complete.  

As someone mentioned before, there is the Osbourne syndrome.  Announce
that the next generation makes the current generation obsolete, and
people will not want to buy any of the current generation which can make
cash flow problems difficult in the time between the announcement date
and the actual delivery date.

This also leads to the next problem, what I term the Supra Modem Syndrome.  
If you announce something that is going to be awesome before you can
deliver, you can end up with a lot of very frustrated people who are
tired of waiting for months beyond when they were told they could have
the object of their dreams.  Some, like me, get so frustrated that they
end up buying another modem, not because they don't want to wait, but
because they have lost faith in the company.  In addition, the company
begins to feel so much pressure that they push the product out the doors
before it is truly ready.  This is bad for both them and the user. 

And as with everything else, there is bad news along with the good news.
How many people are going to be happy when they find out that the only
way to gain the abilities offered by the new chipset is to buy a new
amiga (or have a motherboard swap at the least).  I just hope that C=
an upgrade path for current owners that is as nice as the new hardware.

Tiredly,

Got my 44m external SyQuest the other day, and proceeded with installation
instructions.  I set the SCSI ID to 1, connected all the cables to my 
GVP series II 500+ HD, and flicked on power.  As soon as the status screens
passed, I got a requestor saying "gvpscsi.device 0000 - Unexpected Status
$49/$46", which also had a continue button.  After hitting this button
(several times, this requestor came up frequently (and randomly) during this)
the computer checked for drives, and then requested a boot disk. (my GVP hd
is the normal bootdisk).  I insert a wb disk, and once the startup was
complete, the GVP hd was not present on the WB.  I took out my GVP FaaasstPrep
software, and it reconginized the existance of the GVP hd and of the SyQuest.
I was able to format and install bootblocks on the Syquest, and on the next
reboot, it booted off the SyQuest.
I turned off the SyQuest: same initial problem, booted off floppy.
I unplugged the SCSI connector from the GVP: no problem, booted as normal.

I am stuck!  I've done everything but remove the terminating resistors
and nothing works!  

System: 500, GVP sII 500+, 1/2chip,1/2fast,4fast, SyQuest 44m (external case

John, if your CDR74 is an external SCSI drive (I think it is), you will need to
get the CD-ROM Driver software from Xetec, or you may want to try CDR-FS
produced by some canadian company.  

I have three CD-ROM drives on my six line BBS and they work like a champ using
the CD-ROM driver software from Xetec.  The Xetec driver software supports
CD-TV emulation on your Amiga, and also supports Audio discs.  You can reach
them at 913-827-0685.  I think their package (encludes two pd CD-ROM Disks for
the Amiga, and the driver software) can be had for around $50.00..

Hope this Helps...

When I asked this a while back, I was told to enable Data Cache using CPU.  If
your system crashes, you've got page mode - if it stays up, you've got SC.

Well, we have a new office supply store here (its nationwide also)
called Office Depot. They guarantee to beat ANYONES price. However
they sell the same ribbons for $6.92 EACH! I questioned the manager
who called Sams to verify the price and I was sold the ribbons for
$1.06 EACH! I bought 5 of them of course. What a deal! They guarantee
to beat the competitions price 50% I believe. So, if you have a Sams
and an Office Depot in your town or close by, it would do you good
to load up on ribbons.

No!  Pins 4 and 20 (on data terminal equipment) are RTS and DTR.  These are
outputs!  You never want to connect two outputs together.  There's
probably protection built into the serial ports, but better safe than sorry.

There are two wirings for null-modems I would recommend, depending on
whether RTS/CTS are being used for their original intended purpose (to keep
the terminal from sending data when the modem isn't ready for it), or for
flow control in both directions.

The only difference between the two is with RTS/CTS.  Note that RLSD
(Receive Line Signal Detector) is also know as CD (Carrier Detect).
