First, find Win3.1 drivers that are compatible with your OAK video card.  
There may be some avaiable via anonymous ftp at ftp.cica.indiana.edu.  New 
drivers should help with your "garbage" problem.

As far as the screen being "off center", this may be a problem with your 
monitor.  Some monitors do not sync well at high resolutions and need the 
help of a utility generally provided by the maker of your video card.

I heard a few years ago that there are some pin for pin replacements
for 765 chips. Actually many 765 controller chips have some pinouts.
If I remenber right, the newer controllers need higher clock rates
that those old, so you may have to also change some other componets
as well. You have to check it yourself, I am not sure about that.

In the February, 1993 Issue of _PC World_, in the Consumer Watch column,
it reads:

[In response to a question about RiteMicro:]

RiteMicro is a subsidiary of FastMicro, a company that has been the subject
of dozens of letters to Consumer Watch over the past year and for which
we continue to receive complaints. . . .

The Better Business Bureau in Phoenix (the city in which both FastMicro
and RiteMicro are located), gives both companies an unsatisfactory rating
and does not condone or recommend purchasing from them due to unresolved

Effective with the January 1993 issue neither RiteMicro nor FastMicro

 I'd say yes it does matter.  These QIC80 tape drives, especially the
Colorado are pretty flimsy, low quality items.  They have enough trouble
using a high quality 3M tape properly.  I would hate to see what they do
with an elcheapo generic.

 Granted, if all you want to do is write data to a tape, then they'll
probably work fine.

 The big question is, are you going to be able to restore the data?

 If it's of any value to you, go with something you can kind of trust.

Well, I don't have the manuals with me to give any specifics about my 
machine, but I think the 3-chip parity problem is caused by the BIOS
incompatibility.

This is what happened to me.

I had 4Meg of 9-chip simms and bought 4 more 3-chip simms.  I installed it
with ease and boot up.  The computer would tick for 4Megs then hangup.
CMOS chipset error!  So, I turned off the above 1 meg memory check off and
no problem.  I then proceded to windows and decided to use all 8megs of
memory.  So I open up a BIG TGA file.  Parity error in the middle of loading.
So I put the 3-chip simms on the first bank (making them the first 4 megs).
Now, CMOS error occurs as soon as it starts memory test.  So I turn parity
check off in my BIOS setup.  Now, it runs with no problem.  Windows gave me
no trouble.  Of course, when I installed OS/2 2.0, I stated getting that
parity error again.  
But, my point is that since I was able to fix the problem, at least temporarily,
I believe that it's the BIOS that causes 3-chip simm incompatibility.

AMI Feb/91 (I think).

I posted above about the possible systems that I am going to purchase and I
left out a few important questions.
Addendum:
1.)  Is having 8 megs of RAM that important??  I plan on running windows
software and some DOS stuff.  All the machines I have looked at come with 4
megs.
2.)  Is a 170 meg HD large enough for a machine today?  Originally the machines
I was looking at came with 130 Meg HDs, but I heard that the average windows
prog is 8 meg so I upgraded a bit.
3.)  I am considering all local bus systems, but have a choice between an
ET-4000 card and a Genoa card.  The ET-4000 gets around 4 WinMarks, whereas the
Genoa gets 29 WinMarks.  That seems like a dramatic difference to me, but I am
unfamiliar with the WinMark test and don't know what that would translate to in
actual "speed" benefit.  Can anyone help here?

A friend has an old Leading Edge D.  This is an 8088 machine.  He would

a controller for less than $40 and a drive for about $55.  My sense is that
this should work.  My question is whether there is any limitation in the

Since I do not regularly read this group, e-mail responses will be

Nope.  With most of the current crop of 1" high IDE drives, the actual number
of sectors per track varies from the innermost to the outermost cylinders. 
Typically between 30 and 38 sectors per track depending on the circumference of
the given cylinder.  The cylinders with highest sector density will give the
highest transfer rates and vice versa, because the drive is still spinning at a
constant rate (3600 RPM).

As for the number of platters, most 1" drives have two (four heads).  Typical
number of tracks per platter is often greater than 1200 cylinders.

Core test shows the raw transfer rate as opposed to the FILE transfer rate. 
I've found it to be a better (if still not totally reliable) benchmark than
the hopelessly useless and innacurate disk benchmarks as supplied by QAPLUS 
and CHECKIT.

One word of warning : with SOME disk caches, the transfer rate with core will
report unreasonably high figures (like 10mb/sec :)  Interestingly enough, this
is the case with the old SMARTDRV.SYS but not the current SMARTDRV.EXE.  

Go figure

I know all these queries will not apply to all groups, but I really need some help with a college project I am just starting. I am intending to write a

I have heard of the MPU-401 but apparently you need an additional card
inside the PC to use it, is this true ? Also Ive heard you can get MIDI
interfaces that simply connect to the PC by the 9 pin mouse port or printer
port. Which is easiest, and cheapest ? Also, how do I address the relevant
port/board in C, C++ or Assembler( if needed) to send out data.

All help, or pointers to help will be greatly appreciated !

The difference between a 486DX50 and DX2-50 depend on how much you plan to use
your computer and for what. A DX-2 system runs on the chip at 50MHz but for
external access like to the bus or memory it slows down to 25ishMHz.
Performance is about 40 to 60% of that of a true DX50 depending on the
application running. If it is just working off what is in the INTERNAL cache
ram it flies along very close to the speed of a DX50. If the application
require frequent writes to the bus or external cache, system cards, etc its
performance degrades almost to the point of a 25mhz system. But suposedly it
averages out to the 40-60% of a DX50's speed. games and the like won't slow a
DX-2 but stuff like Autocad, DBASE, heavy software drag it a little. The cost
between DX50 and DX-2 50 systems is narrowing rapidly and it just costs a
little more to put together a powerhouse.

Using 60ns DRAM in place of 70ns is fine.  60ns DRAM is merely designed and
rated to have a faster minimum access time.  

It's somewhat akin to putting VR-rated tires (good for 150MPH) on a Volkswagen
Bug.  It's nice to know that your tires are good for that speed, but you know
the Bug won't go that fast.

On the plus side, if your extended CMOS setup does let you set waitstates on
DRAM read/write out of SRAM cache, then you could reduce the wait state by
another notch on the banks with the 60ns dram and get a .slight. improvement in
overall memory accesses to those banks.

If some IDE drives don't work with a bus frequency higher than 8 mhz,
how can they benefit from being in a local bus interface?
