Subject: Mountain tape backup with 2 floppies, possible?
Organization: The Ohio State University
Date: Fri, 1 Jan 1993 00:37:10 GMT



I have an older Mountain QIC 40 internal tape backup (TD4440) does
anyone know if this will work with 2 floppys if I use a Y spitter
cable like CMS Jumbo uses? Now I have it hooked up in place of  1
floppy drive and would like to be able to use both along with the
tape unit. Thanks for any help.

Essentiallly all the work is done in a single chip called a UART -
which grabs bytes from the bus and converts them to a serial bit stream
(and vice versa), and does the other housekeeping (start and stop bits)
to conform to the external protocols.

You can pull the cover off the computer and look at the part number on
the UART (8850, 16450, 16550).  For your multi-IO board this may not
work, because the UART function may be emulated inside another
multi-purpose chip.

There are a variety of software ways to find out which UART chip is on
your board or is emulated by your board.  DOS 5 and Windows 3.1 include
a utility which will tell you about all your I/O ports. (sorry - the
name has slipped my mind - my pc is at home and I'm at work using a
Sun).  There is freeware in the PC ftp archives which will do the same
thing (again, I don't have a more specific reference - it was posted
here a while back).  These aren't foolproof - some folks have reported
that this software reports the wrong chip.

Since you have a quite new machine, you probably have at least a 16450,
which should run just fine at 57.6 kbaud. And you've got a fast
computer, so feeding it bytes at that speed isn't a problem either.
However, that's not the whole story.  If you are running Windows or OS2
or any other sort of multitasking, there may be long (ie milliseconds)
periods when the computer is off doing other things and ignoring the
interrupts from the UART. During these periods, data can be lost.  The
16550 solves this by adding a 16-byte internal first-in first-out
buffer.  With this chip and a fast computer, you can do 57.6 kbaud data
transfers in Windows 3.1 without data loss.  

If your I/O board has a real 16450, you can replace it with with a
16550 - assuming it is socketed, or if you know which end of a
unsoldering tool to hold.  If not, you can either add another I/O board
(you might have to figure out how to disable a port on the existing
one), or you can simply buy an internal modem, which has its own UART
and gives you an additional serial port independent of the two you
already have.  The internal modem is by far the easiest and cheapest
option, if you can do without the flashing lights of an external.  Some
internals only have a 16450 - ask before buying.

Hi,

The difference between an interlaced and non-interlaced is the way the display
is put onto the VDU.  An interlaced screen displays all the odd then all 
the even rows of the image.  This means that at a high resolution the interlaced
screen may "flicker" as the phosper that coats the inside of the tube will fade
before it is reenergised by the electron beam.

A non-interlaced monitor will not have this problem as it does row 1, 2, 3, 4
etc until the end of the screen, then repeats this.  This will result in a
more stable picture.  A non-interlaced monitor sometimes doesn't quite hit the
inbetween space of the odd rows when drawing the even ones and this also causes
problsem.

After saying all that, I have an interlaced monitor and at 800x600 it is fine.
It does flicker a bit, but not enough to justify the difference in price.

The non-interlaced monitors are more expensive because they need to scan twice
as much screen in the same time as a non-interlaced monitor.

Some video cards will not provide a non-interlaced output anyway, so check this
out.  My Trident 1Mb SVGA has a jumper to choose between interlaced and 
non-interlaced output.

Well, yes and no!

I have found some systems will work with an ST-01/02 but fails to
work properly with other cards.

For example, some of my systems will hang with an Always IN-2000,
boot but flaky on Windows with an AIC but works OK with the ST-01!

One consistent problem I have with the St-01 is that if I use the
SCSI drive as boot drive, the stupid BIOS on the ST-01 always 
claimed that the drive has not been formatted and then offers to
format it for you. My friend who boots from his SCSI lives in 
mortal fear that someday somebody will answer YES and blow his 
300MB HDD data!

Apart from that, I have no experience using the ST-01 to drive 
a SCSI CD-ROM, so I cannot comment on that.

But I agree that ST-01 software support from SeaGate stinks!

Perhaps you should have stayed with the Trident.

I've never switched to OS/2 mainly because of problems like this. Looks
like I never will either if the only decent SVGA one can get is Trident.

Anyone who can call anything associated with Trident "HOT" deserves to 
use their cards 9-) No thanks. I'll wait till NT, meanwhile Windows 3.1

Exactly right, Jim.  Sure, the 486SX is does great when compared to say,

a fine machine.  If you buy one, you'll not be disappointed.

Once upon a time IBM offered a BIOS upgrade but no longer does. There are
3rd party BIOS upgrades available; spend an hour with an issue of Computer
Shopper.

A better solution if you insist on sticking with an XT class machine is to
pick up a new XT motherboard. It would cost well less than $50 to put an 8
or 10MHz turbo XT motherboard with 640K into your case. Of course you would
lose IBM's BASIC ROM (obtain a copy of GWBASIC if this is important) and
the cassette port (you don't use this do you?). However, you will also gain
built-in support for several devices like hard drives.

So why are floppies called 1,2M and 1,44M, when they are exactly 1,2*1024*1024
and 1,44*1024*1024 ?
And hard disks 213M when they are 213,000,000 ? I just recently bought a hard
disk advertised as a 180M Conner. On the hard disk itself, however, there was a 
label of 170M, and MS-DOS Fdisk reports only 162.5M. A call to the vendor gave
me the following story: The hard disk is 180M unformatted, formatted it should
be 170M, which it almost was (169...).
But the thing I don't understand is that the Norton programs call it a 166M
drive.
Any explanations/comments?

I keep getting  1701 post error on my fixed disk when i turn on my 
computer,a 286.
i have a seagate st 251 hard drive and mfm card.

It's like my computer can't see the hard drive or card,it is set in the bios
yet it still says no drive is present,
any suggestions?
