Russ:
Digi-Key is one of my favorite suppliers. They do have SMDs, but not
these. As far as the IO chip and the microprocessor, these are unfortunately
too specific for them to carry. DK does not carry SMSC at all, and the Zilog
line is represented only by the Z8 series.
I never thought of MCM. Thanks for that one.

Have you tried DigiKey. I haven't looked through my catalog as it's buried
in a box right now but they sshould have many of these parts. MCM
Electronics in Ohio also has many items and even if not in their catalog
they can outsorce them many times.

Hello, all:
Well, I'm going to embark on another project--to build the P112
Z80182 SBC. As you may recall, this is a nifty Z80-based SBC that's the size
of a 3.5" floppy drive and uses a standard PC I/O controller for disk
support.
Dave Brooks no longer makes the machines, but I was able to purchase
a bare board from him for $25.
Anyway, it requires a few SMD components which I can locate at Arrow
and Pioneer Standard, but there are purchase minimums that I can't meet. I
can probably order the chips in one-offs but not the SMDs.
So, I'm looking for the following:
BAR43C Schottky diode SOT23, common cathode ; has odd pin
configuration
BAR43 {same}
BCW71 transistor, NPN SOT23
SMSC FDC37C665GT SuperIO chip, QFP100
Zilog Z8018216FSC1932 Microprocessor, QFP100
Anyway, if anyone has a source for these in hobbiest contact me
off-list. Thanks.
Rich

RE: the Sol on eBay ...
Yeah, the guy apparently knows little about what he is selling. He
attributes its name to "Solomon Libes - an editor at Popular Electronics,"
rather than Les Solomon. Even the quickest search on the web would have
turned up more accurate info than what he presents.
Given the bidding is up to $1400+, I may start considering a trade for an
Altair for one of mine!

Well, it seems like I have posting access to the list again, so I'll dig out
this little question that I keep on asking occasionally...
I've got the remains of a Tektronix XD88/10 Unix workstation from the late
80's. I've only got the system unit and the keyboard - no mouse or monitor.
I do have a 16" sony monitor that I know works fine with it though, so that
leaves a mouse to find from somewhere, or to make one from something else
(no idea what protocol or type of mouse the system needs though)
The hard disk is almost dead though, starting to give read errors all over
the place - from memory the system won't boot any more. I expect I can get a
replacement disk easily enough - probably even a modern 3.5" SCSI drive
would work I expect to replace the 5.25" full-height drive. The machine's
got a SCSI-1 drive, around 400MB, but I think SCSI-2 drives will work in
the old SCSI modes won't they? (I have a 400MB 3.5" drive which could
replace it if so)
What I don't have though is the OS tapes (a common problem for 80's hardware
I expect!). I'm waiting to hear back from Tek but they couldn't provide any
help last time I tried a couple of years ago. Does anyone on the list have
such a machine or know someone who has?
Is it worth me trying to do a raw backup of the disk before it fails
completely? I can put it in my main PC at home which has SCSI and read raw
data from it under linux (not sure what filesystem Tek used, proprietary I
expect) but don't know if I'm wasting my time there - I don't know if
that'll give me anything useful at the end of the day anyway. Even assuming
I could find an identical working drive and do a raw copy of the failing
disk onto it (at the block level), would that work - or is there always
going to be some sector translation at a lower level which meant that the
contents of the "new" disk wouldn't make any sense when put into the system?
Thanks for any help,
Jules
ps. I don't know how many of these machines Tek sold, but it feels like
about 5 given the amount of information there is around about them! :-)

Deja didn't have the older archives available for a while now. Every time I
emailed their support service I got an automated reply back saying that it
was temporarily unavailable - I suppose that if this takeover was looming
then that explains a lot.
Oh, I don't know about them having the last 6 months up at the moment by the
way - yesterday afternoon they didn't have some of my posts and follow-ups
>from less than a week ago.
Hopefully there'll be a way of grabbing group archives to local storage -
that'll be handy. I hope they put some serious work into the UI too and
actually make it look like a piece of newsreader software rather than a bad
web front-end (as dejanews was and as the site is currently)
cheers

Anybody have a manual for the subject laser printer? I think it's barely on
topic (at least ten years old) as I recall it being bought sometime before
I moved to the new offices at my old employer in early 1992.
I'm attempting to fire it up after having shelved it for several years. I
bought it in a company surplus auction. Naturally, the VP who used it in
his office misplaced the manual. He's a pure non-techie and he admitted to
me often that he doesn't keep track of such things.
I can't for the life of me recall the term for the electrostatically
charged image transfer belt which picks up the toner and transfers it to
the paper. But the one in this unit is physically damaged such that two
black blotches prints on each page along with a very fine line all along
the length of the page -just off center. Anybody have or otherwise knows of
a junker Action Laser II from which I could buy that part? It's the easily
removable assembly positioned right in front of the fuser assembly.
Next, I have to research whether anybody sells replacement toner carts at a
civilized price -that will tell me whether it's actually worthwile
restoring and using this printer :-/ It'll certainly save ink cartrige$ on
our HP DeskJet we have in the house when printing larger quantities of text
or some monochrome graphics for my schoolwork.
Thanks for your help on this.
-Chris

OK, what on earth happened to the Dejanews archive? Seems like they've been
taken over by Google (leading us one step closer to a single corporation
controlling the entire world, no doubt! :-)
I didn't see any advance warning of this, nor can I see any date for when
the archives will be back online on the site. Are there any other usenet
archive sites out there? (preferably ones that aren't web based, or have a
better interface than the awful Dejanews one - or the even poorer Google
search result format!)
cheers
Jules.
ps. this is serving somewhat as a test message - someone let me know if they
can see it! :)

Must be running netbsd. The DEQNA is the older of the Qbus NICs and it's
ok if
working. If you can find a DELQA which was a newer version that would be
better.
Both can be found as networked vaxen were not unusual.

If the OS is Netbsd then look into the version your running. If VMS
theres something
going on, hard to guess what.

Judging from the web page, http://www.nenie.org/cpcip/, it seems
like quite a hack. People have fit minimal web servers (via SLIP?)
in PIC-based gizmos. Search for "world's smallest web server"
for all the contenders.
You're right, thouh - it would be nice if there was a minimal
TCP/IP / http server with source code, so it could be ported
to other systems. Or maybe there is, somewhere out there...
