The PTP board is also an ATX form factor so it should go right in the Umax case. A problem is that drive cage. The PTP is a square, or rectangular board. It doesn't have the cut-out at the front-top that the S900 does. On the other hand, that area is mostly empty on the PTP. Okay, I've put a picture up at http://www.io.com/~trag . The file name is PTPmoboFront1.jpg. Scan is courtesy of Kaye Yum. Kaye's a great guy. We met on the PowerWatch boards and he's a Gurus moderator now. Anyway, the only thing you'd need is a piece of sheet metal for the standard rectangle in the back of the ATX case which has the proper holes for the PTP I/O ports. When they designed the ATX specification, there was no way to standardize all the ports that folks might want on the back of their motherboard. So the ATX spec. just calls for this rectangular hole in the back above (to the right of) the PCI slots. It's up to the motherboard manufacturer to provide the I/O Gasket or EMI shield (I've seen both names used) that has the right holes in it. Well, obviously PCC isn't going to provide anyone wiht an I/O Gasket for the PTP. So... If you get the other files prefaced with PTP_ you'll see there's one called PTP_template. This is an image that you can print out and use as a template to cut sheet metal to the right size and put the holes in teh right place. These other PTP_ files are not JPGs. You must download them and open them on your desktop. They're PICTs I think. I'm not to up on graphics formats. I just know your browser probably won't open them. They're screen captures I did on my machine using cmd-shift-4. Anyway, there are scale lines on the PTP_template. If you get those to print out to the size they're labeled, then everything else should be the right size. Then you can print it out, cut it out and install the paper template in your target case. Trim to fit, mark for screw holes, or whatever method your case uses to secure the I/O Gasket and when you have all that worked out in paper, then you can put the paper on sheet metal, trace the outline and holes with pencil, and then cut it out with something like a dremel. It's a bit of work, but I don't know another way to get an I/O Gasket for the PTP, unless you have an old PTP case you can steal it from. And even then, it may not secure to the case in the same way on your target case as it does in the stock case. I think I mentioned before that there's a company (something like California PC) which has I/O Gaskets for the S900/J700 on their parts list (they're listed as Storm Surge on their EMI Shield parts list). They had a couple hundred of them a couple of years ago. They're kind of cheesy thin sheet metal, and you may need to rework the edges some to get them to fit a given case, but at least the holes are cut and in the right places. So when putting the S900/J700 in another ATX case you don't necessarily need to build your own I/O Gasket. On the other hand, I think I had to pretend to be a dealer to get them to sell them to me. The 9500/9600 board is more of a problem in a Umax ATX case. The DIMM slots are all up in that corner. Also, the sound and ADB port are approximately where the AGP slot is in an ATX case (where the Apollo board is on the Umax). I think you'd need to trim a slot cover to fit and you must also trim the actual case around the AGP slot hole. Then you'd still need to design a template for the I/O Gasket to fit around the serial, ethernet and SCSI port. I haven't done one for the 9500, just the PTP. The 9500 is a much bigger challenge than the PTP. And the PTP uses a standard ATX PS, whereas the 9500 takes some work to get it to work with an ATX PS. > I have an >extra New J700 case in the box. later Will S >PS Jeff your info on the two machines sort of made my head swim ;-) >Glad someone can figure this stuff out though it was more then most >can deal with... Well, my delusional thought at the time was that if everyone on the list absorbed all the stuff in that tome of a post, then the next time an architecture based issue comes up, I wouldn't need to explain the background. On the next question where architecture is relevant I could just give the shorthand answer, and because everyone would understand the underlying architecture perfectly from my diagrammed post, I could leave out the lengthy background. What can I say? I had just come back from running and it was near 100 outside. I tend to be a little loopy after running. Jeff Walther -- SuperMacs is sponsored by <http://lowendmac.com/> and...
