Hi Dave,
Did this go? If not, I'd be interested. I'm located in Hebden Bridge, so
could drive over to collect.
Best,
Andrew

Hi Bob,
I can't help with your search for 8/e front panels, but you mentioned
"green switch boards". I have a nicely restored DEC LAB-8/e with green
switch toggles. Do you have spare green switch toggles? I would love to
have one dark green and one light green toggle. I don't need the actual
switch

I had some toggles printed for me professionally, but they are inferior to
the originals and the colours don't match.
If anyone has spare DEC LAB-8/e switches please let me know.
Thanks

I'm looking for one that matches the layout attached. I don't care
what model (e/m/f etc.) it's for, but the rotary switch layout needs
to be right and I prefer the matte finish.
I'm working on some code where it would be handy to map the top of the I/O page
along with the bottom of physical memory. An obvious hack is to point the APR
to the I/O page address needed, then set the length so that the address modulo
2^22 also covers the low memory range.
It seems from the
EK-DCJ11-UG-Pre DCJ11 Microprocessor User's Guide says it will abort [the first
processor guide on the shelf]
$4.5.2.2 (p4-7) Page Length Field ... "The block number of the virtual address
is compared against the page length field to detect length errors" ...
$4.7.1 MMR0 <14> Abort Page Length
Ok, but I think that's not what I meant.
Suppose I have APR6 = 17 and length > 1. That means VA 140076 maps to
physical address 1776, and VA 140100 maps to physical addres 2000 which
when masked with 22 bits would end up at 0. The offset within the page is <=
the page length.

OK, a faux descriptor would work round the documented checks which are on block
number rather than EA - there is a hardware overide
I'm delighted to hear that RSTS won't play along and set up for EA overflow

I have tired to print the paddle handles both SLA and FDM and none match
the quality and strength of injected molded paddles.
Unless you print an entire set (light and dark colors) it is nearly
impossible to match the colors also. Even if you were to find the
perfect filament or resin color,
Try printing them in PETG: I've printed several of them for my 8/L and
they equal the strength of factory switches. Even the little pins are
more than strong enough.
PETG does require a higher printing temperature (220c-230c) but is well
worth it and a massive improvement over PLA.
