Decisions, decisions...
I plan on buying an old 68k Mac but I'm not sure which to go with. My options are Performa 638CD, Quadra 650, Quadra 840av, or a Quadra 800... What is so special about the 840av? I know that it is the fastest 68k Macintosh but what AV features are included with it? Thanks.

Info on the Quadra 840 AV.

why do you want a 68k machine? low end power macs are just as cheap and you get compatablity with ppc code

The 840av has a dedicated digital signal processor on the motherboard. Sure, the 040 was powerful in its day, but this made the computer truly advanced in may respects. The av line was the first to support voice command, which has never really taken off, but it was a valient effort. There are also special uses for the DSP, like the Geoport adapter which brought telephony and modem services through the same port. The Geoport made the Mac a great speakerphone and answering machine, but it was a terrible modem.

Anyway, if you are getting 68k, you should always go for an av model.

As for any other posts that are negative against 68k machines, there is nothing wrong with 68k. Yes, they are dated, but they still provide a lot of good work for their age. Try getting a 486 to do what an old 68k can still do.

Uh... get an AV PowerMac... like a 5500/250 DE... or a 6100 AV or something...

All the advantages of the 840AV (or not?), and PowerPC.

OO! OO! If you do decide on a early Power Mac Make Sure you get the monitor adapter cable (fancy combined ADB, Audio out, Audio in, monitor plug to regular Apple monitor plug) that came with em. Them things cost an arm and a leg (for what they are), but you can't use a regular monitor without one.

Actually, the only early Power Mac that you'll need the special video cable for is the non-AV 6100. All of the other first-generation Power Macs came with another video card already installed and this video card is a lot better than the video output from the weird video port.

However, if you do have one of these adapters, you are able to use two monitors with your computer, which is pretty cool.

Hello all,

just let me drop a stick in favour of the Quadra 650. I used one for years, a very robust and reliable machine, fast in these days with 33 MHz including FPU, except the AV equipment similar to the 800 and 880 AV Quadras, but superior to all the ethernet- and FPU-less 68k-Performas.

If you do not need the AV and the Quadra 650 is a lot cheaper, consider it.
