I have had a IIci to Quadra 700 conversion on indefinite hold for a long time and now I want to get this beast put together!! I have to cut out some of the openings on the back panel because the ports are different on the Quadra board. The problem is the metal shielding seems to be secured with some sort of plastic rivets and I won't be able to reattach it once the rivets are broken. Would I be able to dremel the case and shielding while they are still attached?? |

I have thought about this one myself i bought a ci new in 92 and it hurt. I would like to see the finished job keep me posted. As for cutting it you will likley have to use the abbrasive saw in that I would not try to remove the shield

So I finally managed to get the project started. I have most of the openings on the back cut out to fit the Quadra 700 board. I had to cut away part of the RF shielding and may have a bit more trimming to do. I started out using a utility knife and rocking it back and forth to cut away the bits of plastic that were blocking the ports from exiting the back of the machine then came up with the brilliant(?) idea to heat up a carpet knife on the stove and both cut and melt away the plastic at the same time. Not a good idea. The cutting is much easier but the melting plastic makes a huge stink in the house, so if you are going to do it that way, do it outdoors. I have birds in the house, so I couldn't continue with the melting method as they are susceptible to changes in air quality. The IIci board had upgraded memory chips on it, I'm not sure what capacity they are but they were Viking parts and the Quadra board had what looked like stock Apple pieces on them so I can only assume the previous owner of the IIci upgraded the memory at some point. I also managed to find an Apple PPC 601 board on ebay recently that is going in. Now I have to dig up the floppy drive that came with the IIci and the mounting hardware. I have it all here *someplace* but I took the machine apart so long ago I can't remember where it all is now. I'll also need an internal hard drive and mounting hardware. Unfortunately, the IIci/Quadra 700 case does not have an opening for a CD ROM. I think it would be difficult to even find the space internally to mount one, so I think I'll have to pick up an external unit. I also think I need a ROM for the Quadra board as it didn't come with one. I think the previous owner of the IIci took the ROM for another machine as you can also use the IIci ROM to make certain 24 bit ROM machines 32 bit clean the same as with the IIfx ROM.

I've found a dremel with various sanding and cutting attatchments work great for moding cases plastic or metal.

Quote from: "sierraredd" I've found a dremel with various sanding and cutting attatchments work great for moding cases plastic or metal. I had considered that, but from other case mod posts I have seen, the friction of the dremel bit on the plastic melts the plastic and makes a burning smell the same as using a hot knife. It can also take quite a bit of time to get the cutting done. I only have to do some minor trimming on the plastic now to clear one of the ADB ports and there are some places where the RF shielding is still causing some minor obstructions. I think I am also going to have to do some trimming to the bottom of the case as the Quadra board does not have slots in all the same locations as the IIci board so where I had to snap off the tabs, there are high spots under the board that keep it from sitting flat affecting the alignment of the ports.

Well, after doing all the case modding to the IIci and getting everything to work together, (except for a 601 board I got on ebay. Not sure if it's broken or if I'm missing a driver.) I needed a hard drive to boot up with. I pulled the one out of my IIvx and the Quadra worked great. Now, I have two open computers sitting in front of me. The IIvx has a superior case design to the IIci, so it would be a nicer case to use, but would the Quadra board fit? I removed the floppy, CD ROM, power supply and support brace from the IIvx and guess what? The Quadra motherboard fits the IIvx better than it fits the IIci case. All the ports match up, so no cutting. There is a plastic knockout on the back of the IIvx case that needs to be removed to get the AAUI port through and there is one tab on the bottom of the case that needs to be removed, but you can remove this easily because it is clipped in and not molded as part of the case like in the IIci. So now I have the Quadra running in the IIvx case with the internal CD ROM drive that I would not have been able to use with the IIci case. There are no CD audio pins on the Quadra board, so you won't be able to listen to music CD's, but I wanted to use the CD ROM drive for data not music. Also, the internal speakers from the IIci and IIvx cases seem not to work with the Quadra board. They are two pin and the Quadra speaker connector is 3 pin, so I will need a real Quadra 700 internal speaker. If you are going to use a CD ROM, I wouldn't use the IIvx CD ROM. I had no choice at the time, but the IIvx drive is a caddy loading drive. Caddys can be hard to find as they often get separated from the drives they came with and lost or destroyed. The faceplate over the IIvx CD ROM will probably have to be changed if you use a tray loading CD ROM. It is designed to have a caddy inserted from the front, not to have a tray open from behind. If the 7100 uses a tray loading drive, then the faceplate from that would work as the IIvx uses the same case. So, apart from sound issues, one of which MIGHT be an easy fix, I now have a Quadra 700 with internal CD ROM or a IIvx with 040 (hopefully a 601 if I can get this PDS card to work). Other parts donated to the project include 64 Megs RAM from the IIci motherboard to replace the pathetic 8 megs that was on the Quadra board(my thanks to the original owner of this machine for using high capacity 30 pin SIMMS from Viking.) and 512k of VRAM from the IIvx to fill two of the empty VRAM slots on the Quadra board.
