This caddy don't appears to be the usual caddy that
most common CDROM's used. I have one of these
and don't go well. The entry ranure of the CD device
is more THIN than the others, and this don't work.
It can be too a problem of my caddies: I have two NEC
caddies to probe, and any of it works.

Stupid that I did not think of trying SJ.
With SJ entering .R ADVENT starts Adventure also!
I assumed that VBG was for Virtual BackGround, so
nice to be comfirmed on that.
Indeed, I have E11 running on an 486DX2/66, but I
cannot give an idea of how fast it runs, compared
to a PDP-11. Although E11 can be set to an 11/70,
I have set it to /35-40 because that is also the
*real* hardware I have. Never set it to /34(A) or
to /44. Both those systems I also have running.
Next time that I start the 11/35 I will run ADVENT
on both of them and measure the time until the
welcome message appears on the screen.
For the "blinkenlights" check out my webpage.
http://home.hetnet.nl/~tshaj/pdpsite/pdpstartpage.html
then click in the left pane on the link Homebrew 'PDP-11'.
At this moment only the LEDs of the data bus blink.
I hope to add a piece of hardware that 'talks' to Ersatz-11
so that the address bus LEDs are also active *and* that the
switches function as on the real thing. The goal is that
the hardware design can facilitate *any* real PDP-11 console
that has switches and lights, from an 11/10 to an 11/70.
Of course, this project needs the cooperation of John Wilson,
and I had already some preliminary contacts with him.
He also likes the option to connect a real console to the
demo(!) version of Ersatz-11.

The RRD42 is (IIRC) a Sony unit (possibly
with modified firmware). It takes
a "standard" caddy.
The RRD40 is a much older Philips(?)
CD-ROM (1x) and it takes a caompletely
different form of CD holder (often
referred to as "antlers").
FWIW: the RRD43 is a tray-loader and
the RRD44 is back to a caddy. The
first DEC CDROM drive was the RRD50, which
was essentially a tabletop, caddyless
(flip open the top and load CD)
RRD40 (except, I believe, *slower*!!).
I have at least one RRD40 CD holder,
which I can supply if noone nearer
can dig one up (I'm in the UK).

I think they are cool. But then I have been acquiring CoCo stuff for the

A 128K CoCo 3 with box and manuals is probably worth $25.00.

The PDP-1, working, complete, might well be worth US$10K,
but it's unlikely he's got one. Probably a boatload of
Vaxen & -11 stuff. Or maybe even Alpha.

Hello.
I just begin the development of the Univac I simulator. By the moment
I am doing one simple prototype of the CPU with all the Instruction Set
and the Registers, plus ten simulated Uniservos in form of ten plain
ascii files. I don't try to reproduce by the moment the timings or
the exact cycle of the data and/or instructions along the system.
In a later issue I have the intention to convert the simulator in
one Bob Supnik's Simh compatible.
And, finally, I shall try to develop one GUI for the Sim, and here
is where I need some kind of help. All the photographs I have are
in black and white, and I need some help about the real color of the
Univac I components. I am working actually with the Supervisory
Control (the Huge Console of the Univac I) and I need to know if
somebody knows its exact colors: that is, of the Metallic components,
and the light and blinking colors too.
All help should be agreed.
Thanks and Best Regards

Thanks very much, Jerome.
Booting RT-11FB and then running ADVENT still produces

However, VBGEXE works fine !
After the "Welcome to Adventure!! Would you like instructions?"

This means that I am now going to play Adventure. This has a

I'm sure you could/would -- but I'm also sure a lot don't. So trivial
obfuscations probbly work to some extent, more especially in the context of
trawling web pages, where there is no mandatory header labelled "From:" or

Hello, all:
I mentioned a while ago that I got these boards, and I actually received
them last week. To do a refresh, this board is an INS8073-based SBC with
lots of I/O in a compact 4x5 size. Someone mentioned that they may have
access to the manual but I can't find that message.
I need some info on these more than I thought. The kit comes with the board
and parts and nothing more. The silk screen on the board only has parts
designations (i.e., R1, C1, U1) but not the values. Some I can guess at but
not enough to make it work.
The only info that I have is on the 8073 specifically and not the board
itself. A search doesn't turn up much.
Any help appreciated.

What kind of juice do those chips need? 16 gauge seems awfully heavy for
any ICs I have worked with. I assume you know guages, but 16-18 guage is
standard lamp cord and will let you draw 5-10 amps on 110 volt. This
sounds good for a main power input to a transformer, but all ICs I have
worked with only pull at max a few amps at much lower voltages, so you
should be able to use much thinner wire.
I would check your amp requirements, and move to an 18 or 20 guage solid
or even higher if you can... phone station cord is usually 24 guage, but
don't mix it up with the 26 guage multipair cord... the usual obvious
difference is, station cord is 4 colors red/green/yellow/black....
multipair cord is 2 (or more) pairs of striped wire (blue, orange, green,
brown, slate all striped with white for the first 6 pairs)
But that aside, if you strip the standed cord, tiwst the strands in your
finger, and then tin the end with your solder iron (heat the end, and let
it draw solder into it, until it has a nice coat), it will be MUCH more
managable (although it still in general won't stay where you bend it,
other than the tinned end, lightweight alligator clips work wonders for
holding things in place).

I wondered about that. OK, it has to go, too.

I knew about that one; I didn't mention it before because I just took it as
read that I'd need to replace it :-)
Thanks again for the advice. Now all I need is time to get at it -- maybe
this coming weekend.

There's not much to tell, really. It originally belonged to the
University's Psychology Department, which has moved between buildings a few
times, and it was left in a small storeroom at the back of a building they
left some time ago. I bought something from a postgrad in the building,
and whilst chatting he mentioned that the AV technician was also into oold
computers, so I paid him a visit. In the course of *that* conversation, he
mentioned there was a disused PDP-11 that would need moved in time for a
forthcoming building refurbishment, and the rest, is, as they say, history.
I try to make sure that people around the campus know I'm interested in old
machines, and from time to time something interesting turns up :-)
I probably won't have much time to do anything other than gaze at it every
time I walk past, until the weekend, but I'll let you know how I get on.
I'm also trying to sort out the 6000VA UPS (unrelated acquisition) I got
last week, and mentioned on the list. I've got as far as getting it
powered up without tripping the 32A circuit breaker, getting the
diagnostics and status out of the serial port, and have figured out why it
doesn't like the batteries: the two sets of ten 12V lead-acid batteries are
all flat. None reads more than 0.2V :-( I presently have a pulse
generator/charger on some of them, to see if I can get any life out of a
few. It looks moderately hopeful.

Don't be ridiculous! I hardly ever use Usenet from this domain now that my
ISP's news server seems to be unmanaged and uncared for. I usually post

on Usenet.

One good way I've seen to munch the address is...
change "computer.geek(a)computer.com" to
"computerDOTgeekATcomputerDOTcom"
