Hello, all:
Does anyone have a PDF copy of the Motorola 6800 chip datasheet? I
downloaded a copy from somewhere yesterday and the strangest thing happens.
When viewing the PDF, it shows on the screen as a positive image but when
printing, it prints as a negative.
Thanks.

Yeah, but if he'd described putting them in-line the right
way, would that even work? Is there enough power there to
handle three amplifiers, and wouldn't the noise obliterate the
signal eventually?

Well the copy of the OS that I have is an OEM copy of Netware 1.1, so that
would be why I said 1.1, I try to avoid sticking the proverbial foot in the
mouth when possible ;p

What annoys me is when they give horribly incorrect advice. I stopped
by a local radio shack earlier this week to price out some RG6/U for
a new DirecTV dish that I was cobbling together. I needed about ~350
feet of cable. The sales droid insisted that I'd needed to buy three
in-line amps, and install them all at the dish ... (I guess he knew
enough rudimentary english to read the amp packaging, and extrapolate)
What bothered me the most, though, was the authoritative manner in which
he described what I had to do. It took quite an effort to keep from
laughing in his face...
BTW, I bought the coax somewhere else, just on principles...

Not saying the ones in the US are safe or good, but they are not like the
one you describe. They are a white plastic, rather "soft and durable"
material. You can smack then and kick them and step on them, and they
stay in one peice. Also, they don't sell that cross tipped one like you
describe any more (at least I haven't seen one in a long long time).
Rather, all of them end in a jack, and they include one tip of your
choice (for most, some include multiple tips). So you pick the connector
style you need, and then that plugs into the jack on the cord. It is
marked on the cord with "TIP" and the connector has a "+" on it, so you
can align it for either positive or negative tip.
Fairly decent setup, and so far, all their newer style white ones (they
have been selling them for a few years now), have held up well, at least
for me.
As to short circuits and how safe they are... I can't really say. I've
never opened one, and I can't think of a time that I have done anything
other than accidentally set a multi-voltage one to the wrong voltage and
watched my device get toasted (leaving the power wart just fine of
course).

I'm having a bit of trouble geting my new 'shiny' Televideo TS-816 up and
running. It hangs trying to IPL from the hard drive, and I can boot off a
tape, which gets me diagnostics.
The diagnostics look like this:
-----------------------------------------------------------------
Self-testing in process. (TS-816/40 PROM V1.1)
Hit "ESCAPE" Key to boot from Tape ?
System IPL from Tape Drive in progress *
TeleVideo Systems TS-816/40

Do you want to run disk diagnostic? ("Return" if NO, "Y" if YES) Y

It would appear that it's having a problem using the internal hard drive.
I don't have a spare sitting around to replace it with, and the cables
look all securely fastened. Also, the drive seems to be spinning just
fine, and I've cleared the two 'locks' on the bottom for it before trying
to use it.
Does anyone have suggestions for troubleshooing this problem? I'm
knowledgable in electronics and can drag out my o'scope if I need to.
Also, can I hook up a 5-1/4" MFM or RLL hard drive up to this thing? It's
a TS-816/40 (I'm guessing 40MB drive), what should I look for (C/H/S) in a
replacement drive?

Hi
Instructions that would continuously increment the address
are vary useful for debugging address decoding problems.
On an 8080, about the only useful sequence is to have
a pop and jmp, using 4 locations.
It may have been that the 6800 one was a debug instruction
that was designed in.

On Wisconsin public radio yesterday, they were blaming some amount
of 9-11 on Louis Freeh's "I hate computers" policy, and some talking head
claimed that agents were so disgusted by the slowness of their
"386s and 486s that wouldn't even be accepted by churches as donations".

Greetings,
This afternoon I registered my DECUS^H^H^H^H^HEncompass membership
number with Montagar software for OpenVMS. By the way, not knowing
the CPU ID of my VAX, I entered a '?', and that satisfied their
registration script. The last time that I attempted to register with
Montagar, my Encompas membership ID number was rejected, so I didn't
get a CD-ROM back then. A short while ago, an e-mail arrived with the
license to use OpenVMS; alas, the license expires in one year. Will
this expiration date have any effect on the useability of the software
after the expiration date?

I've a Commodore 64-SX (the portable) and I was toying with the idea of
updating its kernel/bios/rom/whateveritscalledonthere so that it could
stretch out the life of its floppy drive.
There was a company called CMD that produced a replacement called JiffyDOS
that worked around lots of the slow repetitive speed transfer problems
>from the disk drives. It doesn't seem like they're selling the chips
anymore.
Anyone have a source for these, or failing that, someone have a recipe for
doing this sort of thing?

Hi,
I recall reading a line on/near/inside a Commodore 64 SX
box advertising that their floppy disk drive:
"Reads data faster than you can type".
Is my memory playing tricks on me, or did Commodore really
use such a line (or something quite similar)? Any pointers
would be appreciated.
BTW, I wasn't convinced that it *could* read data faster
than I could type :)
thanks,

I'd *LOVE* to be able to do this, unfortunatly, I don't have a DECserver
that supports this. Someday....

I'm not sure about the 2000, or the 3100's, however, I've successfully
attached a Multisync monitor to my 4000/vlc, and I believe either my 4000/60
or 4000/90. Of course I used a DEC cable with BNC connnectors to hook up
to the monitor.
Personally I prefer a VT420 on my VAXen to a Monitor. I even end up using a
VT420 on most of my Alpha's.

I doubt you'll find a computer inside. This is a

That's a shame! A couple of years back I asked the classiccmp list what
was the "best" CP/M machine, and the overwhelming answer was "Kaypro." I
like mine. It's rock-solid, and applications, compilers, etc. are easy to
find. The disk i/o is slow, though.

Yes. I have the 84/2X schematics and I'll be happy to scan and email them
to the OP if he/she will contact me offlist.

Hence my review alongside the pointer. I was turned onto this thing
by someone who likes to run a recent release from Red Hat, and look
what it got me: a reason to do that OS upgrade I'd been putting off.
Once I did that, getting SRecord to compile was as easy as I'd been
expecting, and it even worked and did what I wanted done.
I expect that most folks running Linux/*BSD have installed or upgraded
within the last two years and so have a sufficiently new version of
gcc at this point, but I also expect that you (and other folks on this
list) might not.

Can anyone tell me what these cards from a DEC PDP-11/04 are? I've identified some them but I'm not they're correct.
(1) M2763 (2) H-222A (16k x 18 core memory) (3) H-222A (16k x 18 core memory) (4) Advanced Control Corp. card with two FMI (Function Module Inc) 9685 Digital to Analog Convertors (5) same as 4 except it has two Burr Brown DAC-800-CBI-V convertors (6) M7856, (7) M9312 (Boot Strap Terminator?

Indeed it all began with networking CP/M computers. Around 1981 Novell
came to the market with their first networking product, called S-net.
It was a star based network around a specialized server machine with a
68000 processor and a proprietary NOS. It is this machine we are talking
about now. You could connect CP/M machines and PCs to it. Around 1983 the
first version of Netware appeared, called Netware-86. This was a
multitasking file-, print and application server software package that
ran on the PC XT.
I do not know what the exact functionality of S-net was, but I believe
it was multi-user file sharing only.

today i picked up the same Poket Terminal.
did somebody find any information about this unit?
what type of interface the connector is?
It seems, that someone modyfied the connector of my unit, because one cable
is cut, and the connections of the others are completely different than that
of don's unit.
can somebody tell me wich cable(color) is connected on wich pin on the
original connector?

Is it possible to take a few photographs of these machines and publish
them somewhere? I also collect old Novell stuff, and I have an old
original Novell machine too, but it already is a 286 made by Hyundai.
(http://home.iae.nl/users/pb0aia/cm/lroom2.html) I also have an old
key card that you needed to have in your server as a sort of anti
piracy device or otherwise your system wouldn't work, that was used by
the first pc versions of the Netware server system
(http://home.iae.nl/users/pb0aia/cm/lroom4.html)
When Novell was in the hardware business it also sold diskless pc
workstations with the ne1000 and bootrom already on the motherboard,
also made by Hyundai. (I do not have pictures of those)
But I have never seen one of the old 68000 server machines.
Thanks,
Kees.
