Hi Guys
As per previous update I'm off to my silk screen printers
today.
Thanks to lots of help from list members I have identified most of the
different
PDP8/e panel types that exist.
1. PDP-8/e Type A:
Selector switch starts from _vertical (12 o'clock)_ position
If a schematic isn't available, but a unit was made available on loan
to reverse-engineer, I'd be willing to do it. Recently I
reverse-engineered a schematic and the firmware of a Zendex ZX-200A
Multibus floppy disk controller, which replaces both the iSBC-201
single density controller and iSBC-202
Hi Rick,
Call me if you can.

it would only be reasonable if you needed it to compete a display that
used that particular cased unit. adn you really had to have it...
otherwise as a 33 it is vastly overpriced!

Well I guess you could use it for many things. It looks like one paper tape
reader or perhaps punch, I think there are 60 lamp drivers, a few AND gates,
lots of OR gates. A counter. Delay circuits and memories.
So a Trainer is possible...

Hi Jay
Is this what you want me to look at with a view to panel

I'll keep an eye out for other controllers, but I think I will order
an extender and attempt to debug the one I have.

Assuming I eventually get the controller working, I started looking at
my cabling and I don't think I have what I need to hook up the drive.
