I don't really see the point of making several different clone cards when the availability of the actual MPU-401's seem to be nonexistent these days. Only few have beens sold in the past few months on eBay and the prices are only going to get higher when all the interface card owners fight for the last remaining MPU's.

Well, I think it's wonderful that people managed to reverse engineer this highly sought after ISA card. It would be cool if someone could make a clone Voodoo 2 card, but yeah, don't see that happening anytime soon or ever.

I'm sure that's somewhat true, but it just seems that more people are churning out new versions of the card than there are available MPU's for it. I also presume many MPU's were discraded long time ago because the interface card was missing and no one saw a need to save the BOB's. So are there REALLY that many MPU's in the wild? Even if CL has them, that's a niche market compared to the world wide demand. I don't see them posted that often, even if I go through Amibay and other similar forums.

Hi, thanks for posting the links to my card above (I am Lo-tech site owner).

This card was actually developed specifically for a well known musician, the objective being to run multiple MPU-401's on an XT (in his studio). It's a simple board so I thought it may as well be the best and most flexible clone I could make. And if it works, I'll release the rest of the PCB batch for anyone else interested.

i own a MIF-IPC-B card and it works fantastically!!!!!
id like to get another as i have two MPU-401 BOB's but only one MIF-IPC-B card!

then i could have dedicated MIDI for both my 386/DX40 + 486/DX2/80

im still interested in finding out if anyone ever succeeds in running more than one BOB from a single MIF-IPC-B card
that was the original goal of this new design, im still not 100% sure as to how that would be accomplished..
i had told the developer before that i own 2 BOB's and id like to try to get them both working at the same time with the
singular MIF-IPC-B that i have but i havent tried to do anything with this yet..

Correct me if I am wrong, but don't the 1st generation MPUs have issues with anything faster than a 286? AFAIK these speed issues were fixed with the IPC-T and onwards...

i have an mpu-ipc (version prior to the mpu-ipc-t?)
does that mean i will have problems with this on a 386 or 486?

Edit: User doesn't exist anymore either.

He went around and deleted most of his posts when he left - probs ~12 months or more ago.

Life? Don't talk to me about life.

Hopefully there was no drama there. He was a pretty good resource for all things Roland.
