That's interesting... I thought the HP 500c only printed in A4 (half

Subject: NEC CDR-84 SCSI Controller Card
Organization: National University of Singapore
Date: Tue, 10 Nov 1992 08:58:42 GMT

Hail People!

I've ordered the NEC CDR-84 with the SCSI controller card.  Just like to
find out a few things before the package arrives.  Which IRQ and DMA
wouldst the SCSI controller card or cd-rom take by default?  Can they be
adjusted if it clashed with my other devices.  Currently, my SB Pro
takes IRQ 5 and DMA 1, and my Microsoft Mouse uses IRQ 7.  Would these
be problematic?

Also, I'll be trying to hook the internal audio out on the CDR-84 to the
CD-in on my SB Pro.  Would there be a problem findind a connecting wire
to do this?  The CD-in on the SB Pro is a 4 pin thingaming, I don't know
what the config is for the audio-out on the NEC CDR-84.  There was some
entry on this awhile back but I missed it.

Eagerly awaiting enlightenment.

I have a G2K dx2/66 system and the CS 1572FS monitor.  I have noticed that
in all high resolution modes, (ie 800x600,1024x768) I see brownish-greyish
streaks down the left side of the monitor.  These streaks start from the left
edge and continue about .5in.  I have talked to their TECH support and they
have been no help.  I have tried moving the computer, checking the setup,
etc, all to no avail.  The monitor showed these signs with both the ATI ULTRA 
and the ULTRA PRO LB.  I have tried swapping monitors (I got about 6) from 
Gateway and they have all displayed this same problem.  These streaks are
very visible when in Windows and using a white background in an application 
when the application is made in to a full screen.  Is there any one out

Hi,

I'm looking for SCSI Controller and I found interesting advertisement.
According to the D-C-Drives's AD, Adaptec refuses to offer end user
user support. Therefore, they recomend Ultrastor SCSI controller.

Is this true? I think Adaptec 1542B is one of the most popular(?) SCSI
controller. So, is this controller is good enough to work without
support?

Also, does anyone has experience with UltraStor 14F controller?
I'm thinking to buy this controller. i'd like to hear any problem,

  Yes it is. Com1 and com3 traditionally use the same IRQ (4) and so do coms
2 and 4 (IRQ3). Some better devices can be set for other IRQs thus avoiding
this limitation. Solution: set one of the devices to com1 or 3 and the other
to com2 or 4.

PC Magazine had a couple articles on it in the last 3 months.  Apparently
it's a superscalar CISC chip, i.e. capable of performing more than one
instruction per clock cycle.  First superscalar CISC ever made, according
to the article (thus the possible confusion with superscalar RISC).  
64 bit data bus, 32 bit internally running at > 100 Mhz  (or > 100 MIPS,
I don't remember which - sorry :)  16Kb internal cache, 8KB for each of
the twin 32-bit portions of the 64-bit data bus.  The FPU has been
rewritten to be quite a bit faster than the FPU in the 486. 

It's not released for production yet, but Compaq is putting together a
new motherboard to take advantage of the 586 design.  IBM claims they
have a machine whose design will already take advantage of the 586, with
a few minor modifications.

>See what you think about it. If you have such a 586 machine

It's not exactly a 64 bit chip, it appears to be a VERY hyper 32-bit chip.
I don't know if there is a 586 instruction set as such.

This one should go in the FAQ (is there any?).

Just put the cards in the slots and attach monitors to them.
The SVGA card will emulate mode 7 (Hercules mode 7) and off you go.
If you need EGA or VGA you have to remove the CGA-card. Also
the VGA-card will be in 8-bit mode (slower) because the CGA-card
is 8-bit as well.

Hope this helps,

Well, if you pick up just about *any* recent PC/Unix magazine you'll
find *lots* of info.  The printer has 600dpi x 600dpi rez and 8ppm.
Does HP PCL 5 and Postscript 2.0  Holds 250 sheets of paper and 
can be configured with an extra tray for 500 more (750 total).  There's
also an auto envelope option (read wadder ;-)  The printer uses a
new (read different) toner cartridge (~$150 each-OUCH!)

It also can be configured with a wide array of network boards.  The
serial, parallel and network ports can be configured at the same
time and thus several systems/networks can access the printer
simultaneously.   It's ~35 pounds light and smaller than the LJ3si.
Comes standard with 2MB and can be configured up to 32MB.  Has
RISC processor.  It's priced $200 cheaper than the current 3si
and if I remember right, it's about $2199.  The review in _PC Sources_
sez that the mail order price should be around $1400.  I found that
a bit low, but we'll see.  The parallel port is Bi-directional.

Well the only thing left to say is that I don't work for HP, all
this is from memory (aka, fuzzy logic ;-) and I don't and can't
be held responsible for any misleading statement (read lies!) listed
above.  I am, however, in the process of purchasing one.

Well, I think it may be time to purchase a CD ROM drive. I need the experts
on the net to let me know what I should be looking for, traps and pitfalls, etc.

Some things I have questions on:

Format type: HiSierra/(I forgot the second type) is this a function of the
             drive or a function of the drivers.
Block size: Do all drives read at 512k blocks? I know SUN uses 2048k blocks.
Access time: I heard MS set a standard of max. 350ms, is this important? I
             guess I may do multimedia in the future.
Transfer rate: it seems most are 1.5 - 1.6Mb
Buffer size: is this similar to a read ahead cache?
OS support: I use DR DOS, OS/2 2.0, Linux, maybe NT when it comes out.

What do you girls/guys recommend?

Thanks in advance,

An internal modem has a UART sitting directly on the ISA bus?  Or do
they not use a UART on the bus, emulate the UART handshaking, and store
data internally as parallel bytes?  Is it important to me that the
modem have a 16550A UART to avoid data over- or under-runs when
multitasking in Windows 3.1?  Or does all the above vary from vendor to
vendor?  And it's completely irrelevant what kind of UARTs happen to be
in the existing serial ports in the machine if I use an internal
modem?  Can an internal modem be used simultaneously with and
independently of the other (two) serial ports?

Do the current communications software packages support
the FIFO mode of the 16550 ( in particular, ProComm+ for Windows and
your favorite shareware package)? Is the DMA transfer mode used?
