Intel SDK-86
model: Intel SDK-86, 1001940
power: Vcc = +5 V (+- 5%), 3.5 A
power: Vtty = -12 V (+- 10%), 0.3 A (required only if teletypewriter or CRT terminal connected to serial interface port)

History
2016-09-16: board configuration - baud rate. W19 - W26 selects baud rate, only W25 is strapped, which means 4800 baud according to schematics. User's Guide, page 2-9, table 2-10 confirms this.
serial port configuration - W1 - W18 configures the serial port. W8 - W16 is strapped, this is the "TTY" setting, according to schematics. User's Guide, page 2-10 says that "TTY" means stand alone teletypewriter. Current loop, perhaps? Users's Guide, chapter 6, page 6-1, table 6-1 says that "TTY" uses these pins:
7 Ground 12 receive data 13 transmit data 16 reader control 21 reader control return 24 receive data return 25 transmit data return
looks like current loop to me.
"CRT" pins look more like a normal serial port:
2 receive data 3 transmit data 7 ground
2016-09-16: board testing. I connect GND and + 5 V and see if the display works.
board 1 (one of the boards with only two ROMs): writes "86" and "1.2" on the display when powered up. SYSTEM RESET button works. board 2 (one of the boards with only two ROMs): writes "86" and "1.2" on the display when powered up. SYSTEM RESET button works. board 3 (the board with 4 ROMs): writes "86" and "1.2" on the display when powered up. SYSTEM RESET button works.
According the the User Guide, this indicates that the serial monitor is active, and that the local keyboard is disabled (except for SYSTEM RESET and INTR keys).
2016-09-16: PSU - the PSU has terminals from left to right: GND, +5, -12, +12 V outputs. A red LED "power on", a mains switch (up is on) and a fuse holder. I measured the outputs with my multimeter:
+ 5 V = 5.14 V (2.8 % over) - 12 V = -12.46 V (3.8 % under) + 12 V = 13.43 V (11.91 % over)
since the SDK-86 board doesn't require +12 V this is probably fine.
2016-07-14: on a visit to my friendly fellow in town, I got 3 x Intel SDK-86 boards, a homebuilt PSU with +5 V, -12 V and +12 V outputs (it is a standard PSU module inside) and documentation.
Hardware:
1 x Power Supply, homebuilt + 5V, - 12V, + 12V DC output. Used for Intel SDK 3 x Intel SDK-86 1001940, one of them with 4 PROMs (the others have only 2 PROMs)
