The 4000/300 and up CPUs use a different bus for CPU and memory
interconnect.

During a recent pickup of some DEC, I was also given a couple NCD
HMX Xterminal bases. These are the pizza box ones. I was told
one had a bad power supply and the other had no video output.
Given that, I pulled the good power supply and the two network
cards. One card has BNC/AUI and the other has RJ45/AUI.
They're available for S&H.

Firstly, Mentec doesn't have a hobbyist license. Secondly, the
license which they have granted does indeed limit the rights to
use the software to certain emulators only. It does not grant
rights to use the software on real hardware...
You are correct.

I worked at Lexidata from 82-84. They should have been up there with
Sun and Apollo, but they made some bad business decisions. Lexidata
had the patent for the h/w implementation of Z-buffering and should
have 'owned' the solids modeling market. The monitor (from memory)
should have 2 sets of R G B Vs Hs, which accounts for the 10 bnc
connectors. Internally it could probably take sync from the green
bnc. It is almost certainly 1280x1024 and might be non-interlaced
as Lexidat was either the first or one of the very first to have
1280x1024x60 controllers.
Thanks for the memories and I hope this is useful

Hi,
I have been collecting microprocessors (among other things) for a couple of
years. I collect mostly those from the 1970's period - 4,8, and 16 bit
models, but have a few newer ones - all 486 and before. I collect any
flavours i can obtain - Intel, AMD, Signetics, ... Most have either been
given to me, or I've salvaged from old computers - don't worry, i won't
dissassemble an older (working) computers, and I usually keep processor
boards intact with memory ...
Anyway, is there anyone else out there collecting these?
Sure could use a catalogue/ list of available processors.
Maybe it could be called The Chip and DIP Catalog ;-)

Folks,
I apologize if my last remark (regarding FDDI, Ford Festivas, and
using the right tool for the job) sounded snotty. I'm just trying to
stand up for my principles, that combined with the fact that I'm in a
bad mood probably didn't sound very nice. Sorry folks.

Hi,
Well, NBCi finally decided to get out of the webhosting business, so
I need someone to host my website. NBCi was nice as it gave unlimited
diskspace for free. I remember someone posted a message to the list
indicating that he (was it Jay?) was willing to host any "classiccmp"
related websites for free. Can anyone help me out? Thanks....

I've been a whole lot to the junkyard this week. Together with a friend, I
salvaged to 1990 vintage monitors. One is an Idek Iiyama 21" one, which works
fine. I appreciate the fact that it's got both a D9 TTL input, a D15 analogue
input, five BNC analogue inputs and five BNC outputs. The only minor flaw is
the analogue connector, which is a plain D15, not a D15HD. I found that it
used the same "standard" D15 VGA cable as IMP monitors, though.
Anyone heard of some kind of common D15 VGA pinout?
The other monitor, though, is an anonymous beast. It's around 19", and the
label at the front says Megagraphics. On the back, apart from all the warnings
and certifications, it says that it's been manufactured by Zenith, and the
model number is 19MGM2.
It's rather short in the back, which implies (to me, at least) that it's a
monochrome monitor. It's got a D9 female input. The case style reminds me
somewhat of a Xerox monitor (a lot of straight lines, very much late 80s).
The size makes me think that it probably isn't TTL. Possibly ECL, which really
wouldn't do me any good. OTOH, there's a chance that it could be analogue, and
if I'm really lucky, that it uses the "standard" D9 VGA pinout.
Does anyone know anything about this monitor, or have any advice on how to
find anything out through probing?

Anybody know where I can find a Hayes Chronograph? I ran across
my Smartmodem 300 (in original box!) in the garage the other day,
and it showed the "companion" clock in a "stack" on the back of
the box.. I"ve always wanted to find one..

They're often called "repeaters" which is actually a more accurate
description. Yes, they are used to get over the length limitation (you can
have up to 5 segments, connected by 4 repeaters, between any two hosts,
though not all segents can be populated and there are rules about lengths,
propagation delays, etc). They're also used to get over the
number-of-hosts-on-a-segment limitation.
However, they don't isolate collision domains; a collision on one segment
will be faithfully copied to the others.
