Subject: Info on the Amstrad PPC512/640
Date: 15 Apr 92 10:40:16 GMT
Organization: INMOS Limited, Bristol, UK

A couple of days ago, someone posted a request for technical info. on
the Amstard PPC640D.

I own one of these awesome (:-) machines, and I have bought some
technical manuals for it.

For those of you curious to know what one of these machines is, here
goes: It is a heavy (approx 12lbs) portable IBM-compatable PC. It is
8086 based, with a CGA lcd display. It can be run off batteries (normal
alkalines), but in practice the mains adapter is used most (all?) of
the time.

The PPC comes in four versions: either one or two 720kbyte 3.5in floppy
drives (suffix S indicates single drive, suffix D indicates dual
drive), and either 512Kb Ram (and no modem), or 640Kb RAM and a V22bis
modem built in.

When the PPC came out, in early '88, it was quite something. But, of
course, it is now pretty outdated. They are still available new in the
UK, at low prices (I presume that they are not made any more).

I have a PPC640D, which I now only use as a modem for my new 486. The
modem in the PPC is not removable, but a small piece of code that
copies bytes from COM1 to COM2, and vice versa, turns the PPC into a
respectable external modem.

The manuals I have are:

"The Amstrad Portable PPC 512/640" - this is the standard user manual
that comes with the machine.

"The Amstrad  PPC Technical Reference Manual" - this manual describes
the hardware and software of the machine (e.g. it lists registers of
chips, details conectors, lists BIOS interupts, documents software not
documented in the user manual). The preface starts "This Technical
Reference Manual is intended to assis writers of software for the
Amstrad PPC, although in conjunction with the PPC Service manual it will
be of interest to designers of add-on hardware".

"PPC 512S/512D PPC 640S/640D Personal Portable Computer Service Manual"
- this manual contains the technical spec., mantenance and alignment
procedures for the floppy drives, exploded views of the computer,
circuit diagrams, PCB layouts, and an electrical parts list.

If anyone would like more info just ask.

P.S. I am NOT an expert on the machine, neither am I a hardware guru.

Hello all.

I am looking for an I/O board with 16550's.  Awhile back, there was discussion
on the 16550 and some initial problems.  Which of the versions of this chip
are bug-free?

This is more than likely a FAQ so please just email me (no need to soak up net-

Just out of curiosity, did you happen to compare the compression rates
as well?  I understand superstore uses smaller clusters and some other
tricks which can greatly reduce slack, especially with lots of small
files.  If superstor's compression is significantly better than stacker
for a common mixture of files (applications, text, db, etc.) it might be
worth the slightly slower throughput and lower memory.

just excersizing my idle curiosity :)

A query...

	I am using a Hercules Graphics Station card in a 386-33, no not 
the b/w weenie hercules card, the big 2M on board cadstation one.
I am trying to install some textile cad software, and it works ok...
except for one thing. Every now and again, some of the colour pallete
gets screwed up and the borders, and some of the menu areas in the 
display randomly change colour. The software writers have sent a 'hotkey'
fix, which seems to reset the colours to the correct (default), but the 
effect happens so often that it renders the software essentially unusable.
There seems to be some correlation with the time that the software is running
and the frequency of error. The program continues, but with weird colours.
The program uses a ramdisk, I have 8M ram, and am running DOS 5.0
Changing the memory configurations ie; loadinghigh etc, makes no difference.

It looks like it is a problem with the software, but in case anyone has had
problems with Hercules Graphics Station cards, please let me know. Or is there
some quirk of setting up the Herc drivers I don't know about....

Any opinions or advice welcome....

Subject: Adding external floppy drive to PC laptop
Date: 9 Apr 92 19:19:08 GMT
Organization: University of Pittsburgh

General question: I am interested in constructing an external 5.25" floppy
for my Bondwell B310 laptop. I have an IBM PC 320K double sided drive
available for this. What is necessary besides the appropriate power supply
and cable? Will I need to rig an expansion chassis with a drive controller
card or is it possible to interface this with just a parallel or serial
connection/device driver of some sort?

General observation: It is very difficult to get mid-level tech information
for projects of this sort; most publications are either aimed at technical
dunces or those with a dozen engineering degrees. :-(

Any information on this would be appreciated. I would like the added flexi-
bility of a 5.25 drive without spending $2-300 for a commercially produced
drive. 
E-mail would be appreciated - I don't regularly scan this group, although
perhaps if I did this question might have been answered without band waste, eh?
Thanks,

I have "Yeager's Air Combat" installed on 2 computers, one is a
486-33, the other is a 386-20.  On the 386-20, the joystick
response is much jumpier, and therefore more difficult to fly.
Perhaps part of the problem is the slower speed of the 386-20.
Though I'm not sure about that.
I tried modifying the game port board on the 386-20 machine
by increasing the timing capacitors from .0047uF to .01uF.
This did seem to help somewhat.
I imagine that all game ports are not created equal.  The one I
modified uses a 558 timing chip, which I haven't been able
to get a data sheet on yet.

Anyone else have any luck in modifying game port circuits.

All a parity check does is tell the machine that one of the nine bits
has changed since it was written. It does mnot say which one, so the
machine cannot recover. It increases the probability of error by 11% (
since the parity bit itself could flip). So is it better to crash the
system if any such error is found, loosing all current work immediately,
or is it better to ignore the possibility of such errors(and maybe have
the machine crash anyway due to a bad instruction, or give a wrong
answer due to bad data.

JDR Microdevices (408 559-1200) has 8 and 16 bit prototyping cards
with ISA interfaces.  Plan to spend about $48 for the 16 bit interface.

I also remember seeing this sort of card at Fry's Electronics when 
I was in the Bay Area last summer.  

Jameco (800 831-4242) also carries an 8 bit prototyping card for $100.

I'm about to purchase a SVGA card that has an NCR chipset.

This card is from BOCA, and based on the research I did it has
everything I'm looking for:  good performance, excellent warranty
and customer support, 72 Hz refresh, 1 meg video ram,
1024 * 768 (256 colors), a 262,144 color palette, and an excellent
price--I can get all of this for $120.  

What I'm wondering is how much software compatibility would I be
sacrificing because of the NCR chipset?  I was told that I should
buy a card that uses the TSENG4000 chipset.

This card comes with software drivers for major commercial
software packages (Windows, AutoCAD, WordPerfect, etc.) just as
most other graphics cards do.


I'm hoping this post will prompt a discussion, but any advice sent
directly to me would also be greatly appreciated.

Do you have any docs for your motherboard?  If you install new memory
many times you will need to throw a dip to tell the hardware what the
setup is.  Your BIOS won't overcome this problem if you have the type of
MB with the dip switch config.  If you have any docs for you MB, make sure
that your hardware is set up correctly.  If it is, and you haven't put
the wrong type of RAM in, then your bios should handle it.

It sounds to me like you've traced your problems to your local
vendor.  Of course he's wrong.  You can buy 386DX CPU's legally
and openly.  A call to an Intel sales office would have revealed
that.

Well first of all, if your getting only 8 meg, you can't use 4 meg simms
because a 386 MB requires you to populate 4 banks at a time.
(Due to it's 32 bit architecture)
The speed should be 70 or 80 ns.
The smallest amout of ram you can install using 4 meg simms is 16 meg.
Glad I could help.
