    Anyone know of where to get the snap into PCB hole stand offs Gottlieb used in the 80s and 90s?

    Gottlieb Part Number is 23984
    Manufacturer number may be SRS-8-6N per some parts listings, but I can't find anything on the web using that.

    Gottlieb PCB hole size appears to be 6mm (maybe 1/4" hole)
    diameter 7mm
    total height 12.5mm
    Collar / pcb support edge height is 9.4mm

    I see PB resource has old stock, but I would like to buy a bag of 1000pcs or something to include with new boards. People can always reuse the originals, but they go missing. Backup plan is just the really cheap straight columns to be used only when the originals are lost, but it makes mounting a bit more tedious.

    barakandl Andrew, are you making all of the Gottlieb system 3 boards? Any others like 80B MPUs?

    greatwichjohn Sourced a lot of plastic lenses when he made plastics. John, I've heard of Foremost Plastics. Any other plastics manufacturers that can make plastic standoffs?

    I used to buy all my plastics from "Micro Plastics, Inc" but they got bought out by Essentra. I haven't bought any plastics since Essentra bought them but will need to do so soon.

    Essentra part number SRS8-6-01
    Mouser has these at $300/1000.

    I just remade about every pf board that I found in a sys 3 world challenge soccer. Opto, diode, flip sense, filters and etc. Going after low hanging fruit. I can do these boards easily. Mpu's have a lot more development. 80 (b) mpu is on my list. Edge connectors make that one attractive for automated smt assembly.

    Thank you. With a manufacturer and part number I will be able to find them. Should have tried some wild cards searching with the Gtb part number, it was close.

    I use # 03-8022-5 spacer standoff (3/8" tall) from Marco Specialties. I've used them on pop bumper driver boards too without problems.

    I believe Victor Tan ("DumbAss" here on pinside) uses these very same standoff spacers on all the boards he makes. They work very well and snap right in.

    The marco part would be the same as SRS8-6-01 but in black instead of white.

    SRS8-6-01 = 9.5mm standoff distance (about 3/8"), intended for an M4 (#8) screw.
    Dim "B" in image = outer diameter, "C" = inner diameter, "D" = length of end that protrudes through end (add to DIM "A" to get overall length).

    If threads are your flavor we use these at my work (not pinball related but also need to stand off PCBs)

    I also use # 03-8022-1 standoff (1/2" tall) at Marco Specialties for pc boards.
