    i have most everything except the resistors/capacitors and a couple of logic chips.
    i have all my sockets, gals, cpu, osc, 74 logics etc. once we know the missing values from the capacitors/resistors I'll be able to get all I need from mouser and can start my build.

    Default GAL question

    Hi,
    I would like to be sure, GAL16V8-25 can be used in place of GAL16V8-15, can't be?

    @wali7

    Change only the speed, the -25 is more slower that -15.
    Can work well, can slower the gba1000 or can don't work.
    Personally, if i don't able to find a -15 (but i get them to kipper2k when his do a global order) i would opt for a faster version, not slower.

    @kipper2k

    In the BOM that you have posted (bom.zip) ten minutes ago missing some components:
    They are:
    R135
    R136
    R137
    R138
    L104

    and this has n.b. as value:
    RN5

    They are signed on the board with respective pads, must be left empty?

    Carefull ! This is the BOM for the rev. 0 board, the rev 4 is different! (although much of the birdfeed is identical)

    Where to find bom and other specs for rev4? Georg Braun has published complete documentation for rev 0 only, is it possible to find complete docs for rev 4 anywhere?
    I thought the only difference between revs 0 and 4 is pcb layout, but it seems I was wrong

    careful, this is the rev0 bom from the rev4 zip file!

    the zip file has schematics etc for the rev4, but a no complete rev4 bom.
    also the schematics for the rev4 have a couple of missing component values (see some posts higher up in this thread).
