What ever happened to the QuadDoubler?

The 100mhz 68040 CPU upgrade that fit right in the CPU slot of some '040 boards, including the A3640 and required no software or hacks to run, and cost only $200.00?

It was developed for Mac Quadras, but worked fine on A3000/4000's as well.

Do people use these still?

Do people use these still?

I suppose they would if they had (or could find) them.

I recently discovered, actually, that not only does the card work with Amigas, but it was actually marketed towards Amiga users back when it was first released.

I've got a 50mhz doubler in my 4000. Works great, but I had to put a business card under the edge that sticks out from the socket so the bottom wouldn't touch the 3640 and short. Don't know where you can find one now tho.

I was just going through my 6 year old collection of Amiga related bookmarks and seeing which web sites were still around and which weren't.

The BoXer site is still up, but hasn't been updated since 2000 sometime, but they had the link to the Quaddoubler, and the company that makes the Quaddoubler still lists it as available, but when you look for distributers it didn't look promising.

I still use mine in my 1200, thus the 50mhz '040. They show up on ebay occasionally.

See Speed  for speed tests and such.

Were there two different models? I see mention of a 100mhz version on the Sonnet site.

Thanks for doing the search for me, guess I should have started there.

The 100 MHz is a marketing thing. When Apple discovered that th ecompetition talked about the coreclock to make its machines sound faster they eventually jumped on in (and so did 3rd party producers).
The 68040 doubles the clock internally. The core of a Blizzard 1240 40 MHz really runns at 80 MHz. So the 100 MHz thing is just an other name for an 68040 clocked at 50 MHz, and that is about how fast an 68040 could go without nytrogenecooling.
