Halted has a bunch of FR4 proto boards from a company called "Syntax"
They were clearing the shelves the last time I looked, though, and had the
stuff marked down.
I don't remember their being a manuf adr on the packaging though.
Got this barebones 486 mobo. I'm trying to setup a 20
gig Fujitsu MPG3204AH drive. Types 1-46...then there's
47. I'm looking for the parameters as I type this. Has
anyone accomplished this? What about a newer cd-rom
drive? I don't have any 3.5" drives at my location,
but I know that somewhere I have a Win98SE boot cd (I
made it). Don't think I have any 5.25" boot floppies
either. I'm a mess! Trying to get some images burned
onto floppies, so I can play :). I doubt I can get
this working today. I did make that hard drive
bootable some time ago, but the P166MMX unit wouldn't
boot from it. I don't have a clue.
If anyone can call me, that would be great LOL!
8016260<area code 732>. I can't get my dialup stuph
working, and I had to drive to a nearby hotspot w/my
laptop just to do this! Man am I a mess.
Can't find a 3.5 anywhere in my stash. That would
make everything work. O man.

not the one with the "pop-up" lcd, but didn't Amstrad
make a Atari ST-looking model (essentially a whole
computer in the keyboard) with presumably an 8088?
Can't find it on old-computers.com. Not much but the
above mentioned PPC-640 shows up in an casual google
search.
Actually maybe it had an 8086.
Actually maybe the thing I forgot to bid on (a long
time ago) didn't have an Intel proc at all, and the
auction lied or was misinformed.
Though off the subject, I'm desirous of obtaining the
Franklin PC 5000, 6000, 8000, you know that tawdry
looking brown peecee thing. Offlist please.

P.S.: Got the LNW-80 yesterday. It doesn't work properly, and I can't
lift it easily due to an injury. But, my friend Tom will stop by and
help me get it running.
I can't wait!

There is also another "all in one" PC Clone similar to these two
machines, though not as nice looking...
VTech, the manufacturer of the Laser 128 series of Apple Clones also
made several PC Clones.
One of them was the Laser 512XT. I have one of them. I'm missing the
Power Supply for it, so I don't know if it works. I haven't been able to
find one on eBay or anywhere else.
It's funny that the PC20 / PC200 was meant to compete with the Atari ST,
since Atari also made several PC clones.
Every company did, even Commodore at the time.
I think my favorite PC Clone was the first one I've ever used, the
Columbia MPC. Though I've used several PC Clones over the years:
I liked the Mindset too. Although I don't have one of those.

A couple of questions pop up on this Northstar diskette discussion. First, was
the oersted rating the same for all of the N* Horizon (and Advantage?)
diskettes? And to expand it a bit, what about other hard sectored diskettes ...
Heathkit, Vector Graphic, etc. And what about the 8" floppies? My knowledge in
this area is nil and I don't recall ever having read anything.
Second, it seems to me that someone has already made a punch for modifying
soft-sectored floppies to hard sectors. As Tony says, it shouldn't be hard to
do. As such, would there be much of a demand for such punches?

Okay, not ever having learned or used Pascal, what are (were?) some of the
limitations of Pascal for production environments?
For 5.25" Diskettes, a friend made me a template by taking a piece of
plexiglass and punching the holes as a guide in it.
I used that template to mark the disk with a silver pencil (not a lead
pencil, but a coloring pencil with some wax in it) and then used a
regular hole punch to make the holes.
Another friend had a metal template made from some thin metal that was
bent over so that a disk could be inserted into it, the holes marked
with a silver pencil and then punched using a hole punch.
I rarely had a DDSS diskette fail on either side. And never had a DSDD
disk fail. Though I usually bought Verbatim, Maxell, Elephant or Wabash
disks. Even BASF floppies were ok. Though BASF Floppy drives were AWFUL.
I did (and do now) have a Wangtek Flippy Drive with the Percom label on
it. This drive didn't need extra holes punched since it had two sets of
sensors mounted in the drive. You just flipped the disk over and it worked.
I'm amazed that I used to think paying $30 for 10 180k diskettes was a
bargain...

Hi,
Thanks for the replies.
I've probably seen some of the web sites mentioned as I have downloaded
various manuals and documentation for the system.
The processor board has the provision for 1K EPROM, which isn't installed.
I'd assume it's for a 2708 device. Unfortunately I cannot program these
devices, so I can program a 2716 and do some mods to the processor card to
make the 2716 work and show only the 1st 1kbyte.
In my spares I have a few Dynabyte and Microbyte RAM cards (both static and
dynamic), an old MITS 8800B CPU card (which needs some serious TLC), a spare
ZPB processor card, some weird S-100 Inc 4K EPROM card which looks like it
can take 8 x 512byte, or 4 x 1k or 2 x 2k EPROMS, a Vector Graphics ZCB
processor card, and a few S-100 blank prototyping cards and a 4-slot S-100
mainboard.
I can wire-wrap up one of the proto boards as an EPROM card if I need more
and run the DOS all in silicon, if this is possible. So, if push comes to
shove I can modify and use one of my 8080/85 debug/monitors and let it run
on the Northstar.
I guess the hardest part is getting a set of drives that will run on the AD3
card, along with the necessary diskettes. I rechecked the disk controller
card and it is clearly labelled "Micro Disk Controller MDS-AD3", which makes
it the double-density diskette controller. I do have another disk controller
card, by Delta Products, that has a 1791 FD controller chip on it, but I
have no doco for this board.
However, the first thing I need to do is clean-up the system, blow out the
dust, fix the blown caps and then go through the downloaded documentation
that describes how to test/verify the various boards are operational.
Again, thanks for you replies and I'm going to join them into a single
document for reference and also go to the various links you have supplied to
see if I can get more information.

river
Hi all,
Just came across this page (well, someone
posted it to another email group) and thought
some of you might like to take a look at it.
http://www.science.uva.nl/museum/rampspoed.html
Among the usual rubber turning to liquid/sticky
stuff are dirty keyboards (under the keys),
mould on old monitors and a harddrive that
is damaged beyond repair :(
