I found this site through a backdoor. I recently purchased a PM 9600 motherboard on eBay. The listing called it a prototype and said it had onboard ultra SCSI so I was a little intrigued and bit the bullet and purchased it even though I originally just wanted to resurrect a dead 9600 for my very young daughter to use. Well, the motherboard arrived and I quickly realized it was quite an oddball. The seller knew nothing about it's origin or anything else and I'm tempted to request my money back per his non-DOA guarantee. Of course, I could not find any references online for the part number, but there's a strange slot on the board labelled VCI, so I Googled VCI motherboard and came up with CaptainZ's forum and webpage on this site. My motherboard certainly sounds like one of the PowerExpress Manhattan describe in an earlier forum:
Here's the auction where I bought the motherboard:
The same seller actually had two of these for sale and someone else bought the other one.
The RAM slots say "NB DRAM 3.3 VOLTS." I've tried many different configurations with the parts I have. I've tried a 32mb stick which I think may be PC66 that came with a Beige G3 that I sold long ago. I've tried a bunch of different PC100 sticks, all 3-2-2. I've tried my original 9600 350mhz processor, an XLR8 zif carrier with an XLR8 350mhz G4 processor, a Sonnet 450mhz G4 PCI processor, and a Powercomputing Powerbase 240mhz processor. With the first three processors I get a "chime" which is not a chime but actually a recording of someone saying, "I believe I saved this company" and then someone else says, "kill me!" With the Powerbase processor I get no chime at all. I have not gotten any video output at all, neither from an ATI 16mb 128 card, nor from the onboard video port. My original PM 9600 did not have a ROM card installed, so I don't have any ROM card to put into the ROM slot.
So, if anyone can please tell me, what's the consensus on this motherboard so far? Am I wasting my time with it or is there something I can do to get it going? Or is it a museum piece?
