Hi
The angled edge connectors are to decrease the insertion/extraction
force. The DEC engineers used to do that to their extension boards.
I see no reason why they would not fit a PDP8. Provided you know where the
Omibus signals are.
PS does any body know where in the UK I can beg or borrow a processor board
set for a PDP8/e. I have memory loading fault on my 8/e that?s not n the
memory.

Does Q-bus really require that the edge card fingers are angled like
shown in your picture?
No it doesn't. But the russians done that with theyr QBUS Board copies
and it works out really good. (Their boards are metric sized, they wouldn't
fit)
Oh, and the site you chose to share the picture pops up webcam porn
ads when I go to look at the picture. I suggest you use something
else that isn't trying to throw porn in my face just to look at your
board layout.
Ah ok, I'll make a copy and load it on my own server. I'll mail this to my
friend.
Prices are heavyly depending on the number of
boards made, so I anyone
want's one or mor, please mail me or my friend redhead.kc85 at t-online.de.
Have you looked at batchpcb.com?
No.

Ive mailed this to an other guy some minutes before, I'll simply copying
some sentences here:
I would like
to know the price range, including shipping to the US for
one and for two boards.
Shipping isn't really a problem from here to the US (the other way around
really is a problem when I look at ebay, approx $45 for an 11/03 CPU from
the US to germany..), we have an "registered international Letter" wich
should be work out approx 5,50 Euros (Euro x 1.32 = US$) for 2 PCBs,
(even more bords, the Letter with a weight below 500 gramms costs 3,45 Euro
+ 2,05 Euro additional for the registering and insurance for approx 43
Euros
(the last from the memory, since such a parcel from me got lost at USPS in
the US in the past).
My Friend made the following statement:
"Ich wollte mir 5 St?ck Q-Bus Lochrasterplatinen als Prototyp anfertigen
lassen. Das ist nicht so wirklich billig.
Als Kleinserie lohnt sich das bereits ab 10 St?ck. Dann kostet die Platine
je 39 Euro. Dann sogar inklusive L?tstopp, Aufdruck, Gold und anfasen.
Interessenten haben sich auch schon gemeldet. Mit meinen 5 Platinen sind es
schon 12 St?ck. Ab 18 St?ck sind es nur noch 27 Euro. Je mehr desto
billiger wirds."
That meansi, that he wanted to make 5 boards for himself and that isn't
really cheap. A small batch ~10 pcs will be 39 Euros each with the solder
stopping laquer, the component print (signal numbers) gold plated and
an chamfered conncetor.
With an order over 18 peaces the price is 27 Euros. Wer are currently at 15
peaces. (I take two, maybe one more..)
We know that is not cheap in any regard, thats why we are looking for
people that wanting such boards also to order more....
BTW: This is a non profit price, we wan't such boards to have fun with
PDP-11's, not to make money.
I never seen a PDP-8 in nature, so please one of the people that know this
should answer the guy in the other mail above if the boards would fit to an
PDP-8, I simply don't know...
Kind Reards,
Holm
