    Sure, but it take some days. Its the Pic from the Seller. Soon as it arrive i make better Pics from it.
    I find this interface on Shiggsys site too.
    PC I/O for SFX Development stands on it.

    After gamesniped posted the snasm box for the card I have I was outbid. I guess it's destined to never be used again.

    Unless you ever decide to sell it or die and your family sells it.

    Can you confirm the chips?

    All that's really clear is that it's an 8-bit card.

    IC1 - 684 - ISA decoding w/ hexadecimal switches
    IC2 - 132 - probably also address decoding
    IC3 - ?
    IC4 - 125 - probably data input
    IC5 - 74 - probably control output
    IC6 - 374 - probably data output
    IC7 - ?
    IC8 - ?
    IC9 - 125?

    Hmm, I thought it was half of an "EPROM emulator" (in-circuit programmable SRAM) as to be expected, with the rest on the cart, but without seeing the cartridge or tracing out the circuit, not certain. Now I'm not so sure since it only uses 10 ISA address bits, some of which must be used for decoding... There aren't enough register bits to page a full MB of memory now... With the 10-register bits and 10 address bits it would be if control was address decoded (PC address output/SNES data isolation vs SNES address output/PC data isolation). It's VERY unlikely this is just for software communication with a SNES, maybe another register is on the cart.. Very convoluted design!

    Assembler, do you feel that you have might have worked up the courage to pry it off now? ;-) I am sure we would all love to see some closer picture of both sides of the mini snes and mainboard if its not too much trouble :icon_bigg

    That's a really cool find - incidentally, that 3x3 inch PCB is a "Super Nintendo Gateway System" - they were used in the seatback units in aircraft inflight entertainment systems so the passengers could play SNES games. It's also got RAM for loading the cart image into (but only about 16 megabits, IIRC). I have a box of them somewhere that I grabbed with the intention of making a SNES devbox, but I never get round to doing anything with them.

    I don't see why not. I'll take some shots before I pack it for the move.

    I've never heard of that before, sounds kinda similiar to the Sega Megajet... Any chance you could upload some pictures of that?
