There's a rather wide selection of video cards that were available for the 650. Find out their capabilities and choose wisely. Usually the aftermarket, e.g. Supermac, are actually stronger than most of the Apple cards. Also, there may be the possbility of an accelerator card or a cache card which will go in the shorter non-nubus slot. By the way, I hated the case which has only the advantage of containing a (SCSI) CD drive, so I put mine in a Quadra 700 case. Works great and SCSI optical drives are available to the external plug if I want, but really a pain since working ones are rare. I mostly use an extra hard drive in a separate case. If I could find a good USB interface ... :)

Also, OS9 should work as well. The early Apple laser printers, the big heavy ones with the HP/Canon laser engine, are extremely reliable if you can find a working one. Also easy to repair since they usually only need parts that are easily replaceable but the power supplies might be hard to come by. If you go that way, I may have a source. Also, check out
ThePrinterWorks.com

Upgrading the drive was priority for me. I used a 4GB IBM enterprise drive. Had to subdivide the drive into a number of smaller volumes because of the OS volume size limitation. You might also be able to find an ATTO SCSI card which could speed things up by allowing a wider SCSI interface. SCSI SSD? I dunno. Could be expensive.

I found this forum from Low-End Mac where I had been searching for info on Mac Quadra 650s. Forgive me for asking stupid questions, but I really am a novice where Macs are concerned.

Several years ago one of my suppliers - a photo lab - liquidated their Macs and bought new machines. I bought this Quadra from them for $50. It came with a 68040 CPU, 1M video RAM, 48M system RAM, a keyboard, mouse, hi-res color monitor, CD and a 1 GB Apple HD that had an OS and some other software installed on it. There was no documentation.

I added a StyleWriter 1200, a few cables, a network interface and bought a copy of Claris Works 4 and OS 8, all from eBay or the local computer store. After setup I verified that it booted but never used it for anything; it had no Internet access and all the other machines around were PCs or Commodores. The Mac was a "decoration", if you will. It looked appropriate sitting on a student's desk in a boy's bedroom.

Last week in the process of cleaning and such I tried booting the old girl. Nada. That's when I found the low-end Macs site and learned about the 3.6V battery that backs the PRAM. I got to the battery (toast) and found a replacement. The Mac boots once again, and now that I have popped the cover I have become intrigued with the hardware inside.

I've got some more RAM on order and a wireless interface so I can connect to the cable modem / wireless router. But I look at the bare slots inside the case and wonder what could go in there.

And that's one reason for posting here: Does anyone have any suggestions for NuBus cards that are suitable for use in this Mac? The on-board video can do (at best) 640x480 at "thousands" of colors, but I'm guessing one upgrade would be a video card. What else can go in there? And do I want to upgrade OS 8.0 to 8.1? I understand you have to reformat the HD to install it.

Thanks for your suggestions,
Charles Hudson
