Welcome back to Amibay.
Thank you all for being patient. The server migration has been completed and we are now running on the new server. At the same time vBulletin was completely upgraded from version 4 to the latest version of 5.
The site is a bit different to before so take some time to look around and get used to it. Let me know if you have any questions.
Please visit the help and privacy sections linked from the bottom of the site. They contain our updated site rules and a lot of information on how to use the new site.
It's great to see members back and I hope you enjoy the work I put in.
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
im looking for one of these cards trying to get a second one, i have one already, but i have two mpu-401 bob's and only one mif-ipc-b card
if anyone is selling a fully assembled card im interested - i also need a backplate for my first card.. if anyone can help me with that
please msg me thanks so much!!
and thanks again to all who have helped make these types of hardware available for those of us interested in exploring the mpu-401
wow theres a throwback.! i used to LOVE that show.. i forgot all about it.. i remember being so hyped up when the intro to the show came on!! i was probably like 6-7 years old when that show was on the air
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
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.
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?
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.
Update: 3 manufactured cards have been sold. 1 manufactured card and 1 manual prototype is in NY. 6 manufactured cards and 1 manual prototype will be / are en route to NY.
