A friend of mine just received a genuine IBM 5150 PC (64K/256K Sys Board,
65 Watt Power Supply, Keyboard AND CASSETTE interface, only 5 expansion
slots).  He asked me if I could get it working.  It was labeled "defective
hard disk".  I have several questions:

       1. Does this machine support EGA or VGA video boards?

       2. Does this machine support 1.44M or 1.2M floppy drives?
          (The floppy controller is missing anyway - so I'll have
           to replace it)

       3. There appears to be a relay on the system board next to the
          keyboard.  It is marked "Omron" (Cash Register Fame?).  Does
          anyone know what this is for?

       4. This system board has two 8-position DIP switches.  The docs
          I have from an XT only mention one 8-position DIP switch. 
          Could someone email the meanings of these switches?

Thanks!

Any hints will be greatly appreciated!

I am having problems with the following ESDI configuration:

Drive:
  model ST2383E
  size  337M
  head  7
  cyl   1747
  spt   54


Controller:
  model WD1007A-WA2
  mode  WD1005-WAH
  sector translation enabled


The problem is that when the drive is accessed the computer locks-up for
about a short time, and then it works.  An example to demonstrate the
problem:

1.  Time to low-level format:     8hrs
    Time for a surface analysis:  60hrs
    Time for a DOS format:        8hrs

There is obviously something drastically wrong here, but I don't know what
it is at the moment.

Has anyone got this combination successfully functional before?


Regards,
Phil.

Hello,

	We were cleaning up the offices of some people that were recently
let go, and I found a rather unusual video card. It has a Vga connector (15 Pin DB), but it also has an RCA single pin connector on it. On the board itself, there are 2 EPROMs on it. On one of them, it says:

	VGA-TV 104
	Willow Peripherals 1989

And on the other it says:

	SD
        Willow Peipherals 1989

	1. Can anyone confirm that this board can display VGA images on
	a normal TV screen?

	2. Does anybody know if Willow peripherals still exists, and if 
	so, their phone, fax. or BBS #?

Thank you in advance for any information.

Whoops, you lost me there!

I hate Microsoft mice. I spent the money on a Logitech Mousmeman. :-)

But seriously,

I was recently getting quotes on PC systems. I was after the fastest
486 I could find with 16MB of RAM, 600MB+ of disk and a Hercules
screen. (SCO Unix box - paying an extra $100 for VGA didn't seem
worthwhile :-)

I didn't expect anyone to have this configuration in their ads. I
appreicated the vendors who did have nice ways to work out the cost of
this system without me having to ring them.

In my opinion, the fact that places like Zeos can offer a machine in
any configuration that you want is one of the advantages of dealing
with them.

It is possible to add the chips in your system  if the manufacturer 
recommends 80 ns. But be carefull. Do not use chips with different speed in 
one bank.

[...some queries about using two monitors on one PC]

I have successfully used a Hercules and VGA combination in my machine.
It works very well on the BORLAND products (BC++ and TD).  Switching
your active card from one to the other is done by MODE MONO and MODE CO80.

I have also written a <PRTSCN> ISR which dumps the contents of the current 
screen to the inactive screen.  This program is extremely helpful; e.g. if
you refer to the top of your file a lot to check on members of your data
structure, just dump it to the other screen to save this paging around
in your document/program. If there is sufficient interest, I'll UUENCODE
and post (sombody just tell me which would be the correct binaries group
to post to).

Having the two cards in your machine has one drawback (apart from requiring
more desk space):  Your VGA card switches into 8-bit mode and SLOWS DOWN A
LOT!!

Hope this helps.

I have a problem with an ESDI.  My controller is an Ultrastor 12F
w/32K cache. I have a Magtron 170M disk connected, and I want to
add a Fujitsu 415M as a second drive. 

Problem: The Ultrastor setup utility doesnt recognize the second
         drive. When in the drive parameter menu, the second drive is
         listed as type "none", 0 cylinders etc...I can access the 
         second drive(Fujitsu) if I set it up alone. So the problem
         That the drive connected to the middle of the controller
         cable is not found.

Some facts: 
         1) the second drive(Fuj)(middle connector of controller)
            has the terminator resistor removed
         2) both drives are set as drive 2 as specified for a twisted
            controller cable
         3) there are no master or slave switches
         4) both drives are hard sectored (35 sec & 54 sec)
         5) both are set to spin up on power up
         6) yes, Ive tried new cables
         7) the connectors are on correctly (ie pin 1--->pin 1)

Please help! any info is appreciated.

I own an AMI FastDisk EISA SCSI caching controller. I run a Micropolis
1684-7 HD and an APS/ Archive Python DAT tape drive on my SCSI bus now
without a problem. You had previously had to use the int13 drivers with this
controller under OS/2, with a performance hit, but with their latest ROM you
will be able to use the Adaptec drivers. I'm waiting on the new ROM's now
which are shipping.
The technical support I've received from AMI has been superb. I do know that
everyone will not agree with this. I base my assessment on the fact that AMI
has continually sent me the new versions of their ROM's for the FastDisk and
allowed me to download the latest versions of their EISA configuration
utility from their BBS as they are released. They troubleshot a problem with
a hard drive I had been using, after I sent the drive to them, to be a
conflict due to the surface mounted firmware (in a Seagate 296N) and are
arranging for Seagate to send me a brand new drive with new firmware which 
will work with their adapter at no expense to me.
Needless to say, I've never experienced this level of service from any
company yet. I'm also shocked that Seagate is so accomodating as well.

I've been happy with my Micropolis 1684-7 which stores 337 MB, on the low
side of your needs. I don't have experience with other SCSI drives other
than the older Seagate mentioned above.

    Anyone have a configuration of an adaptec 1542b and a soundblaster pro
    in the same box? The 1542b has a conflict with the soundboard that
    causes the machine to hang. If I pull the scsi board out of the machine
    then the problem goes away. I've checked the IO port addresses, IRQ's
    and DMA channels and they are different on the 2 cards. The hang can
    be caused by just running the test program that came with the sb-pro
    soundcard. I seem to remember a while back hearing something about the
    bus mastering DMA on the 1542B and the DMA on the sound card not playing
    well together.

Hi all,

I just upgraded my computer, and thought  would post about the experience
for all those interested.  If you are one of those who thinks that the 486SX
is lame, you might want to read this.  I changed my mind enough to buy one.

I had a 286-12 (!GASP!) on which I was trying (READ:not succeding) to
productively run Windows (!Boy, this guy really is up in the night!)
Well, needless to say, my WinBench results left more than a lot to be
desired, so I decided an upgrade was in order.  The biggest dilema I had
was trying to decide whether or not to upgrade the motherboard, or just
get a new computer.  I wanted a new computer, but I would also like to get
Local Bus, and since nobody can decide on a "standard" standard, I was
a little hesitant to buy just yet.  Well, I thought I would persue the 
motherboard upgrade just for the fun of it, so I called a local distributor
and asked about it a little.  I was VERY pleasantly surprised a what I
found out that day.  I was thinking about just upgrading to a 386-40
motherboard temporarily until I was comfortable with getting a local bus
machine, but the things I found out made me decide otherwise.  The 
motherboard I finally got was a 486SX-25 with 128K of external cache. I
got this for $239! (yes, that included the CPU).  So I added 4M of RAM
to bring the grand total to <$400.  This in itself was pretty incredible to
me, but a couple of things about the motherboard made it even better.  This
mother board has the extra pin in the CPU socket, so it is pin compatible
with both the DX and the SX.  Not only that, but the bus clock speed is
hardware configurable between 25, 33, and 50 MHz.  All that need be done
is change some jumper switches.  Well, I bought this and installed it in
~1 hours, and had not a single serious problem not related to my genetic
stupidity.  The speed increase was incredible.  On almost every benchmark
I can get my hands on, I see and 300-500% speed improvement.  Dos based
applications run lighting quick, but windows apps are still a little slow.
(Not surprising since I am still using my old 8 bit VGA card).  However,
whereas it used to take about 40 seconds to load windows and get through
my .ini file, it now does the same in about 10 seconds.  The increase in
RAM allows me to run a 2M smartdrive, which brings the effective disk
throughput up to 4-8 Megs per second (however, I think the benchmark is not
very selective about the way it select data from the disk, so this is probably
out of proportion).  Overall the system is much more productive (READ: FUN!),
and I would highly recommend the upgrade for any 286 user, especially 
considering the seamless upgrade path all the way to Intel's proposed
100MHz DX2.  Well if anyone has any questions, feel free to mail.

Good day all,

Steve

BTW: This motherboard was designed for 50MHz operation, not juiced up to it.

Subject: Video memory and UART access
Date: 27 Aug 92 09:26:22 MDT
Organization: University of Utah CS Dept
Distribution: w

I have a question for some hardware knowledgable gurus out there.

I'm developing an application where I work, that interactively uses the serial
ports and the graphics display.  Basically, it's like Compuserve's CIM 
interface, but for a completely different program.

My question is this:  I know that writing to the video display causes an 
inordinate amount of overhead, mainly due to the wait states involved, however
if I'm writing event the *smallest* amount of information to the display while
receiving information, the incoming information seems to get lost.  This is
on a 386-40 machine with 16550AFN UART chips.

The graphics library we are utilizing writes directly to video memory,
completely bypassing BIOS, so I know that isn't the problem.  I even asked them
if for some strange reason they were shutting off interrupts when they write
to the screen, and they say no.  

So my question comes down to this:  Does writing to video really cause that 
much of an overhead that a 386-40 machine, equipped with 16550AFN UART chips
should suffer loss of data when accessing the video memory?  That's the only
conclusion I can come to.

Any comments would be welcome.

Sounds like you may have formatted it and didn't partition after.  Look

reboot of the day (the machine is powered off overnight). Also,
the processor chip seems to be generating a lot of heat (in fact
after 20 minutes or so the processor chip is scalding hot to
touch). Is it conceivable that when the processor chip is hot 
the reset circuitry may be having problems with a software reset 
attempt? Is it normal for the 486 processor chip to be so hot? 
Is the motherboard defective? Please e-mail the response, 
thanks in advance.
