Do you have any issues with outputting any resolution aside from 640x480 when changing the clock? Maybe stupid question, gotta ask though.

I take it the resistors are just setting the boot up frequency. This is neat but I wish I had a full 040 in mine, and not an LC. I've heard they don't overclock over 33MHz well.

I think the IIfx had a lot of performance left on the table, it used a bunch of ASICs Mac OS didn't apparently do anything with (I've always heard).

I swear I was watching a video about some of the CPU development Apple was working on in the 90s. It was the reason they bought that Cray too. Here it be:

I'm surprised Apple didn't really do any dual or quad chips for an actual server platform, that might have been able to take advantage of it. I know Applefritter used to be hosted off a weird prototype ANS.

Just in quick perusal at work, this is very neat. Excellent work. I'll let the more technical members scrutinize it, though, first before giving you a thousand internet points.

Depending on the price and the distance, it might be worth it. A IIci is a decent little box.

It looked so boring and unacclerated looking, it wasn't even worth mentioning. Might be one of the 'big' 128K cache cards, though.

Doesn't look like an '040 on there, so probably a cache card. Just my two cents.

My soldering skills are beginner-level and I managed, even with a bobo battery-powered soldering iron. They are tiny though. I was a bit more bold. Just take your time. Completely forgot about Powerwindows, I even used to use it back in the day.

I would suggest it. I've been meaning to move my ZuluSCSI to one of those. WD Purple are one of the SD cards I know of with wear leveling. "High Endurance" itself doesn't really signify anything, though.

Neat (y)

Honestly, I'm not surprised they didn't try to implement the weird multi-processing of the multi-604s since they were such an edge case.

Pretty much nothing, really, except some edge cases. But ... You did get to say I have TWO processors in my machine. That was something back then.

I wonder if that processor card in the PowerExpress Rom jpg was a dual 604ev card.

I want to second that. I would definitely pay for a 475/605 L2 cache card/thingie.

I think Steve Jobs actually calls out that weird need to make their own Apple-version of commonly available hardware/software in one of his keynotes. You'd think it would have been cheaper too, since Apple was pretty strapped for cash in the 90s.

I know that overclocking the "High Performance" cards from the 604ev powered 8600 and 9600s to 400MHz was a thing. I don't know if they had success getting to 450MHz+ on those chips, though. It'd be neat if we could tie some L2 cache to them and run them in a Beige G3 or B&W. I'd love to see...
