From what Im seeing and sort of remember, the 8600 came with a 250MHz 604ev on the low end of the scale. The fastest 604e Apple shipped was 233MHz, like you mentioned.
I just wiggle around the mouse. My eyes do catch that moving insect. Like a cat. I think you can set up macOS to 'shake' the cursor, about the same thing but I don't have to set an option that says I'm older.
Yeah, cards that could output two different display were still professional I think at the time (usually had two GPUs on them).
I actually saw the dual display ixMicro card on eBay once. I remember the vram packaging was different than the usual Twin Turbos.
Yeah, it was very noticeably faster with 2d than the Rage II in my Powerbase at the time. I do remember using the Hawkeye control panel too.
Plus, like has been mentioned, they did have some weird font cache thingie that sped up text (or something like that). I remember the drivers/control...
I like them and I plan on getting one soon but I don't personally see value in getting a used one. I upgraded to SSDs when they first started coming out and I still DONT like the idea of a used and worn out SSD, thats non replaceable. Non-upgradeable ram, while not necessarily a deal breaker...
Used M-series Macs to me just seem to have a lot less value than used older gen Macs of yesteryear.
I used to look forward to getter the cheaper and more available Powermacs when they were several years old. Older but serviceable.
Electronic waste?!?
Oh no! That's not electronic waste that's good stuff. We gotta start buying those ridiculously overpriced stuff on eBay to make sure that gold recovery is never an option!
It's be interesting, but you'd have more luck trying to get an adapter for AGP to PCIe. From what I'm seeing they were vaporware (I just did a quick search, though).
That's if MacOS would even know what to do with a AGP to PCIe adapter or a newer-than-it-or-drivers PCIe video card that you...
Apple used some pins for their adc stuff that were originally unassigned on the AGP connector. They were used on 8x AGP which is why you have to tape em off.
I swear I was reading about someone doing something along this lines a little while ago in a G5 or something I can't seem to find the article or post, though.
I don't think that's a PCI slot in the Cube, though. Just because it looks the same DOESN't mean it is. You're probably out of luck...
