I'm installing two laminated (doubled-up 2x12") beams and eight jack
posts to hold up my dining room floor from underneath. I already
installed one beam and four columns in December. Ah, the trials of
being a mainframe collector.
Peace... Sridhar
I'm busy fixing a Olivetti P6060 but I'm stuck and do have some questions.
Is there somebody who has a service manual or a schematic diagram of this computer or from a P6066 (same kind of machine).
The computer is sometimes starting up with errors but I don't know what they mean, sometimes with just the busy-LED is blinking and no display at all.
So I need desperatly some kind of technical paper about this machine...
Regards Rik

Yes, it does. Check that the cable that came with the Mac is a
straight-through Ethernet Cat 5 cable, not a crossover (pins 1+2 at one
connected to pins 3+6 at the other; ie the orange and green pairs).
It could also be an autonegotiation (speed/duplex) problem, but I'd
check the cable anyway, becasue that's usually easy to do by eye.
Sometimes Macs have been supplied with crossover cables which work fine
on devices that have ports which autodetect crossover -- some hubs and
switches do this to make interconnections easier.
I once was on the receiving end of a rant from a visitor who had a
crossover cable, though neither of us realised it immediately. I
tested the socket, which was live and my Fluke OneTouch got a link and
a DHCP lease. I connected it to his Mac; that showed a link. I tested
his cable, which showed as a crossover. I told him that was the
problem. Not withstanding the "Wiremap Error" displayed on the
OneTouch, he insisted it was our network at fault, and "of course" his
cable was the right type "because it works at home". I gave him a
brand-new patch cable sealed in a polythene bag and left him to get
over it.
BTW, there is no colour code convention for patch cables, but we like
to use a local system that helps to prevent most accidents and
puzzlements: grey is temporary, purple is crossover, black is serial,
and pink ("barbie-net") is telephony. Anything else is "Just
Ethernet". It might be wise to adopt some similar convention, at least
to distinguish crossover cables.

If you can please send the diagrams and the instruction set for the
EPROM of the Studio II,this is something I have started to think abbout
lateley.

Hi,
I just received my production version of the KM11 maintenance boards.
Once I build one and test it, boards and kits will be available. Both
will include a parts list and assembly instructions (kits will of course
include all required parts). The boards have gold edge fingers, solder
mask on both sides and a top silk screen. Here's a link to the
prototypes:
http://www.shiresoft.com/pdp-11/boards/index.html
The difference between the prototypes and the production boards is that
the prototypes were all gold plated and the production boards just have
the edge fingers. The rest of the board is tinned.
The bare board is $35 and the full kit is $85.

Hi Tom,
I did not check my copy of "Intro to Programming", because on an
earlier search for a detailed description of the IOTs for a specific device
(how it works and interacts with the pdp8), I remembered that the RX01
was not among them. I do have the description of the RK05 IOTs, but
that is to big (capacity-wise) for a floppy disk. Perhaps I will someday
have a go at it to simulate RK05 with a 100 Mb ZIP drive ... :-)
Meanwhile, the link that Vince posted got me started: including the
(standard a lot of) comment lines, the "#defines" and memory allocation,
I have all IOTs coded in some 800 lines 6809 assembler.
I guess that max 200 lines more will make it complete to put the RX01
in the simulator. As I did the DS32 and the RF08 simulation already,
I have some experience in how to go about, and with the help of Vince,
debugging was not too complicated (the interrupt mechanism got me
puzzled for a while).
thanks,
- Henk, PA8PDP.

I have the PDP-8e Intro to Programming (1970). I'm not exactly sure what
you're looking for. If you think it's in there, I'd be happy to look for
you. However, all I see here are IOTs for TU58, drum disks, scopes,
recording voltmeters, TTY's, and etc. Nothing that explicitly says RX01.

Hi folks,
does anybody know anything about this HP1000,21MX etc. card:
Part No. 12665-60011, labeled "serial interface"
I did not find any suitable information on bitsavers and don't know
where to look. If anybody knows that card...
Perhaps it is the standard serial interface/tty interface?
Please help....
Thanks,
Philipp
Sorry to intrude with an OT question again.
It's currently 1:15 AM EST -- is anyone out there awake and willing to help
me debug a web page glitch? I've got free long-distance on my cell phone so
some live support would be great. (I'm probably just doing something stupid
on my page and overlooking it...)
Please reply off-list -- thanks!
