    Hi Supernova, if Peter doesn't have any left, I might just have a PCB left over from the batch I did way back then. I'll check tonight and let you know. I can solder it up for you, but I doubt I have any backplates left

    I installed the card in my XT tonight and I'm now playing King's Quest 4 with amazing MIDI sound. Thanks for the excellent work Bryce and thanks to Keropi for answering my endless stream of MIDI questions in PM. :P

    The Roland "standard" is IRQ 2( it cascades to 9) and address #330

    Hi Heather,
    glad you like the card. The original cards didn't actually have DIP switches, the settings were hardwired, so I assume they have to be as following: I/O = Off-Off-On-On-Off-Off (I/O address is then &330 to &337), The IRQ has to be INT 2/9 (the first switch) ON and all the rest off. These were the permanent setting for Roland equipment. I just added the DIP switches because (A) it was possible and (B) It might make other things possible such as using multiple cards in one machine or even using it with other hardware expansions.

    Bryce.

    Hi Bryce!

    Great work on the card. I just picked one up and was hoping you might be able provide information on the DIP switch settings. I believe the IRQ one is simply turning one switch on for the IRQ and the rest off, but I'm not sure about the settings for the Address switches. Would you please give me a quick rundown?

    Thanks!

    Heather

    Cool that everything worked out fine. I don't think you should be mentioning prices/price trends here though

    Prototype #2 and 6 manufactured PCBs arrived today and are all confirmed working. I want to thank Bryce for his excellent design and engineering skills!

    This concludes Project MPU for now. With the Bryce and NL replicas there is now ample supply of MIF-IPC-As. And this year has seen more OEM MIF-IPC(-A)s on eBay than ever before.

    The value of BOBs has also gone up.
