Request for Pyro 68040 accelerator pics

For anyone lucky enough to have a Pyro can you please post pics of the front and back of the board? We know that these are reworked Quadra Overdrive cards and I'm really curious to know how the hardware differs. I see configuration resistors on the board, but also the glue logic could be different.

I've never owned a Pyro accelerator, although I have a number of NOS Newer Technology accelerators.













 







These are the best pics I have, maybe someone else can provide close-ups. 

Hallo, today I have learned that my cube has a nice symmetric serial number :)



My cube board with Pyro accelerator

 

I did not want to reduce image size and loose information, so due to 5MB size limit, the pictures have been split to multiple posts.

Ok this matches the mac version I have. If you are able to post a picture the bottom of the cpu I would be very grateful. That is where the configuration resistors are.

So are we saying that the Pyro update for the NeXT cube is the same as some Mac upgrade that might be more readily available and might be compatible with other NeXT cubes?

Not to get anyone's hopes up, but yes that is my hypothesis.

Hallo @barcher174 , I do not want to kill the board or Pyro.
Do you know of some good instructions about how to safely remove and re-add the Pyro?

Or can the picture of "the bottom of the cpu" be taken without removing the Pyro?

Only go as far as youre comfortable, but its as simple as pulling jt straight up out of the socket and reinserting it.

Wow can you share any pictures, and what was the name of the Mac upgrade product and what company(s) offered it?

Very cool! Thanks so much.

Also by newertech its the quadra overdrive cpu. Same packaging and everything.

Hello Brian: I sent you my NeXTstation with the Pyro chip on it consider it a donation to the cause for as long as you all need it. hopefully you all will be able to reverse engineer it so we make these available in the future. also it looks like it differs from the photo's above t

Tested it and yes she works https://youtu.be/Kln4ESgFPOY

I also found this which looks like the Mac version from newtech https://www.worthpoint.com/worthopedia/newer-technology-quadra-overdrive-1812044723

Fingers crossed that PCB board is MAX 2 layers.

Yeah they have that on the Amiga as well Amiga Quaddoubler (https://bigbookofamigahardware.com/bboah/product.aspx?id=270) and link on Amigaresource.cx (https://amiga.resource.cx/exp/quaddoubler) but is limited to only use 50mhz on o4o@25MHz

QuoteThe Quaddoubler is not strictly an Amiga product but an exception has been made because they were frequently used with the Amiga. The Quaddoubler is a small PCB (2" x 4") containing either an 040@40mhz or an 040@50Mhz with a heat sink. Some versions may also have a peltier cooler attached. The idea is that you remove your existing 040 and replace it with the Quaddoubler increasing the speed of your machine. Several models of Quaddoubler were produced and not all are suitable for use with the Amiga. The Quaddoubler used must be a multiple of the bus speed of the accelerator, for example if your existing accelerator has a 25Mhz 040 then you can only use the 50Mhz Quaddoubler, not the 40Mhz version.

Other than the requirement for a cpu socket, was / is the pyro a drop-in upgrade? There is no other soldering / modification required on the motherboard?

They were reverse engineering a Quaddoubler on M86KMLA:

I feel like I have seen Gerbers for a clone somewhere... (nope, it was an 060 adapter: https://www.pcbway.com/project/shareproject/68040_to_68060_adapter.html)
