Cool,
Got one at home that looks just like it.... I've used it as a dumb terminal
so I know mine works. If you don't find any better info, let me know and
I'll open it up to see how it's wired.

Hi,
I e-mailed three people regarding their checks for what I'm supposed to
ship them, but haven't gotten any replies or checks. I wasn't subscribed
to the list at the time, perhaps you replied to the list? At any rate,
e-mail me personally about this.

Did anyone else see the Miller Beer commercial with Norm MacDonald (of
Saturday Night Live fame) and Marc Andreesen (of Netscape fame)? More
proof that "Nerds have Arrived". :)

Does anyone have a spare IBM 3363 optical controller card for a MCA bus? I
recently sent one to someone, and it got damaged in transit, so I'm trying
to find one to replace it.

PS>> was there ever a such thing as a double sided 3363 optical disk?
Here's a short tidbit I found in today's paper:
Talk about good rebounders--Mick Jagger's ex, Jery Hall, appears to have
taken up with one of the world's richest men, Paul Allen, who with Bill
Gates founded Microsoft. Britain's Daily Telegraph says the model, 43,
is vacationing on one of Allen's yachts in the south of France. Allen,
45, is way richer than the Rollling Stone--$22 billin to a few hundred
million--plus, like Jagger, has a liking for rock, playing guitar in his
own band, the Threads.
Geek *IS* chic!

Normally there is absolutely no problem in not using all of the disk.
RT and the DU handlers will only care about what you tell them about
(via PORT,UNIT,PART). The only thing you might have to worry about is
a program which uses the SPFUN which allows total access to the disk
(which is not something which you will find in any of the standard RT
utilities). If you only run distributed software or your own code,
there will be no problem (modulo any bugs that might be lurking).

Finally the weather was agreeable, and I was able to have the PDP-11/44
running out in the garage without getting it to hot out there tonite. So I
got my Hardware problems solved, and as a result I've gotten RT-11
installed on the Hard Drive I wanted to. Which brings up the question, is
there any harm in not using all the space on a Hard Drive when you have it
partitioned with RT-11? I don't care that I can't use the space.

Wow!. I am impressed (very). Although I often thought some of the stuff
in the RK05 service manual was a little OTT. Those drives _are_ pretty
robust.
(The HP drive that we're discussing here uses similar technology to the
RK05 and will have much the same flying height, etc. So I sould guess
that drive will be similarly robust).

I assume you mean the dust caps over the ends of the absolute filter and
not the filter capacitors in the PSU. You mean that drive had no airflow
at all? Again, Wow!

:-).
RK05s (and similar drives) are good to learn on, because it's difficult
to get a fatal headcrash. I've seen it happen once, or rather I got to
change the heads after it had happened. That head had visible scoring
across the pad. I suppose it might have cleaned up, but I had new heads
in stock anyway...
But most of the time if you stick in a damaged platter or have other
problems, you get the 'ting, ting, ting' noise long before the head is
ruined.

Moving day is quickly approaching, and I need to trim my collection down
quite a bit. I'll be going through the majority of the hardware this
weekend and posting a more complete list of available items then. Until
then, I have the following items (some of which I'm sure I'll eventually
kick myself for getting rid of) available.
To keep things simple, I've included enough to cover shipping costs in the
continental US in these prices. Feel free to make other offers if these
prices seem out of line - I'm really only looking to recoup some of the
cost of packing and shipping things out during a period when free time is
at a premium.
