Hi Guys......
First, I want to say Thanks to Peter for starting this forum!!!!!
And... for those that don't know me here, I was a long time member on the Mackie forums, and while this may be a bit rude as a first post here (and I apologize about that) I just happen to have the eproms that upgrade, the MDR to HDR status... you can find them here..... http://www.ebay.com/itm/190571913913?ssPageName=STRK:MESELX:IT&_trksid=p3984.m1555.l2649
Check them out, they work great. You can check my feedback on Ebay about them, and there has not been one single problem, all positive feedback on them.
