The various estimates of how many were made are all less than 200, and some dude on ePay had three of them in the original box!
Must have been one of these rare opportunities that never come again if one doesn't take them. Had one a few years ago with an AlphaServer ES80 for small money but no way to fetch it. In hindsight I should have made it possible.

Well, at least it doesn't have to be downclocked by 33% as for my Yikes!.

But I like my 7300, since I rocked one for years.
I fully understand and I personally also love to upgrade my existing machines. But it's often cheaper to buy a whole system that has a specific part included then to hope to get this part alone.
Say were you able to find any 128 MiB 5V DIMMs for your 7300? I've read that they were supposed to work with such modules.

If Apple were to produce a similarly modular, easy to expand Mac today, I doubt Apple would be able to keep up with demand. Unfortunately, they're probably spending millions instead trying to create a kewl new form factor with proprietary connectors and glued and soldered parts for their promised "pro" machine.
I agree. And I always find it surprising what upgrades were available for the (Power) Macintoshes. I mean who would have expected to be able to run a GHz PPC74xx in a 7300?
This is very uncommon (nowadays) in the PeeCee world. Of course there are exceptions, e.g. one of these exceptions is the SNI D992 motherboard with i440FX chipset. This is actually a D970 PPRO motherboard modified to host two Slot-1 CPUs. As both VRMs are socketed, it can run with everything from Klamath to Coppermine (and maybe also Tualatin) with appropriate adapters and VRMs.

Thanks for the information, I have to check that out the next time I get the machine out of storage.
