PDP-8/i Front Panel PCB
- foo is a messed up version of the indicator PCB of an 8/i front
panel.
- M900dec is a drawing of DEC's M900 paddle card, which contains
the indicator drivers, as well as connecting to the front panel cabling.
- M900 is my version of the M900 indicator driver card, which
provides through-hole (ribbon cable header) connections as well as DEC's
surface mount.
- d-cs-8i-0-27 is a schematic of the M900 indicator sockets in
the 8/i backplane.
- 8iPanelDec is a drawing of DEC's indicator PCB, using the
surface mount ribbon connectors.
- 8iPanel is my version of the indicator PCB, allowing through-hole
headers for ribbon connection, as well as DEC's original surface mount.
- 8iPanelLED is a version of 8iPanel with current limiting resistors suitable for
the use of LEDs instead of indicator lamps.
- LEDPanel is a version of 8iPanel with current limiting resistors suitable for
the use of LEDs instead of indicator lamps.
- LEDPanelmpsl is a version of 8iPanel with current limiting resistors suitable for
the use of LEDs instead of indicator lamps.
- protol is a version of my indicator panel, broken in two, so it
could be ordered from a protoype shop.
- proto2.brd is a panelized set of six M900 boards, suitable
for ordering from a prototype house.
- 8iSwitches is a drawing of a replacement for the switches PCB.
- 8iSwitchesOK is a checkpoint of the replacement for the switches PCB.
- G793 is a pull-up and clamping module for the switch register of the PDP-8/i.
