There was no such rationale.  It is a simple artifact of the way real-mode
segmented addresses are converted to linear addresses by shifting the segment
and adding the offset.  The only reason that addresses wrap on the 8088/8086
is that those two chips don't have a 21st address line.  Since the 80286 and
up have more than 20 address lines, the address doesn't wrap unless external
circuitry forces the 21st address line to 0.

BTW, the first known use of what is now called the HMA was by Quarterdeck's
QEXT.SYS in mid-1987, nearly two years after the IBM PC/AT was introduced.

Date: Wed, 9 Sep 1992 20:08:02 GMT

I'm planning to buy a 486 system for home use where I want fast Windows
performance, a high quality (probably 17" or larger) color monitor, fast
disk I/O, a high quality laser printer, high-speed (fax)modem and a
reliable tape backup subsystem. I've been talking with a number of
salespeople & friends, and so far this is what I've come up with:
   486/50 DX cpu w/256K cache
   Sony 17" 1604 monitor
   Fujitsu M2624FA SCSI disk
   Bustek SCSI controller
   Orchid Fahrenheit graphics
   Keytronics keyboard
   brand X mouse
   Brother HL10V laser printer w/2MB RAM
   3.5" & 5.25" floppies
   USR Sportster 14.4 faxmodem
and the usual serial & parallel I/O ports, etc.

If *you* were putting together a high performance system for your home use,
and had to get it in the next 2 weeks, what would you do differently than
I've selected?

Thanks in advance!

I'm planning to buy a 21" monitor for a PC.  I've pretty much narrowed it down
to:
   - Idek MF5421A
   - NEC 6FG
   - Hitachi CM2187
   - Taxan (can't remember model number)

The specs and prices are pretty similar, now that the NEC's street prices 
have taken a bit of a dive.  On paper the Idek looks best; it has a .26mm
dot pitch, and goes all the way up to 1600x1280 (although at only 60Hz, so
I don't know how usable this feature would actually be).  Overkill for now,
but I expect an investment like this to last for several years, and who
knows what ATI or S3 will be selling next year.....

Anyway, I don't have the opportunity to see any of these except the NEC.
If anyone out there has opinions on these monitors (and especially if 
you've been able to make a comparison of two or more) I would be grateful
to hear from you.  I suggest e-mail to me, and I'll post a summary of any
information that I receive.

What version of CPBACKUP are you using ?
I have been using CPBACKUP with my CM250 for about a year and never had
any problem.  How often do you clean the head ?  I find out that 
the head gets dirty very easy.  I used to have to clean it once every 
4-5 full backups.  Now I use pre-formated tapes and only need to clean 
the head occasionally.  Also, always do a chkdsk or run NORTON DISK Doctor 
before doing a backup.  This will probably eliminate the "error
reading file" problem during backup.

I am contemplating selling my Epson FX-286 printer. (It is a VERY solid
9pin NLQ wide carriage printer - but I've only used paper wider than 8.5
inches once or twice and it takes up too much room.)

I am thinking about either the LQ-570 which is Epson's 80 column 24pin
printer with scalable fonts, or the Action Printer 3220 which is also 24pin
with scalable fonts.

The LQ has multiple paper paths and more built-in typefaces and can handle
single feed paper and envelopes along with pin feed.

The Action Printer has fewer built-in typefaces and paper paths, but has a
50 sheet cut paper bin included and can stand on end to take up less real
estate. With the optional push tractor it can also use pin feed paper.

With the AP's tractor, the price is about the same for each printer.  Has
anyone used either (or both) of these printers, and can you tell me what
you liked or disliked about one or both?  Is current software supporting
the scalable fonts (especially non-Window stuff)?

	To make it simple - all printer ports are bi-directional. 

	BUT!!!   They are 8 bits out and 4 (YES FOUR) bits in. These are your
data lines out for the printer and the sense lines for such things as BUSY,
PAPER OUT, etc.

	SOME printer ports have the option of allowing inputs on the 8 data
lines. This is what people mean when they are looking for true bi-directional
parallel ports.

	So why do the things like tape backup work? They can and will use the 4
bit lines to pass data into the system. The better ones will use a true
bi-directional port automatically if it is there.

Yep, you're right.  I was quoting specs by memory and missed the

        ALL NI! (with a 1280x1024 refresh of 70+ Hz !) 

BTW.  I phoned Philips Tech support about their new monitors.  They
have a 17" (16" viewable) flat-screen, .26 dp, 1280x1024 up to 100Hz!
Yes, 100Hz!  They call the high-refresh technology FastRefresh.
The monitor also has all digital controls, memories, manual degausss,
an LCD (like Mag I think), and looks very attractive (I personally
don't find the NEC fg series very nice-looking, although I don't
doubt their quality).  The tech rep said the target competitor was
indeed the NEC fg series (Philips has a 14" to 21" complete line).
Check out Sept. 29 PC Mag pg. 94.

I'm gonna match the Ultra Pro to the 17" Philips... can't wait! :-)

I am familiar with this, but I have a question about the relationship
between the two PICs, specifically with respect to priority handling.

In a single PIC situation (e.g. the XT), and with the normal IBM PC
configuration of the PIC, the IRQs have a strict priority, and use
the non-specific EOI to signal end-of-interrupt.  Once the PIC has
signaled an IRQ, it won't signal another interrupt of the same or
lesser priority until that IRQ is 'ended'.  (sorry for being boring).

In the two PIC case, when the primary has received an interrupt
request from the secondary (i.e. on IRQ2) and has signaled this to
the CPU, what happens when the primary gets another request from the
secondary before the interrupt has 'ended'? The primary must assume
this interrupt is of higher priority (else why would the secondary
signal it), so I assume the primary will signal the CPU.

Can anyone comment if I am right in making this assumption?

If no, then a device on IRQ15 (once it generates an interrupt) will be
blocking a device on IRQ8-14. That doesn't sound right.

If yes, then I see a potential problem with the DOS/BIOS software
re-direction of IRQ9 to IRQ2. In my Phoenix BIOS, the secondary PIC
is EOI'd, and then IRQ2 (INT 0Ah) is invoked.  At this point the
device that thinks it is hanging off IRQ2 goes merrily about its
business and at some point EOI's the primary.  

The danger is this: another IRQ9 (=2) can be invoked, and if the ISR
isn't re-entrant, then a mess might ensue.  If so, then perhaps this
is a reason for warning users to avoid the IRQ2 in at ISA bus.

Of course if the ISR actually hangs off IRQ9 (i.e. INT 71h), then the
ISR will be expected to send an EOI to both, and it can protect
itself against being re-entered (assuming it wants to). (But checking
mouse.com from Windows, I see that it favours INT 0A, not INT 71.)

If the DOS/BIOS redirector at INT 71 were to invoke INT 0A, and send
an EOI to the secondary *afterwards* then other problems might ensue
(e.g. if the INT 0A handler were to wait as the keyboard handler does
in a PAUSE situation), but overall it seems like a safer approach
(then EOI'ing first).

I was considering buying an amdek multisync monitor that was used for $200,
and I would like to know the average life span of these monitors. 
When I say these monitors I mean any multisync monitor or this one. Also, could
someone explain what an interlaced multisync monitor is capable of displaying.

Thanks James
