I have now obtained a manual for the Brunswick/Briarwood "Aspen" home pinball machine. I have scanned and digitally cleaned up the general machine schematic and it's posted here:

I'm sure it will help those Aspen owners or future owners - nice

According to the Aspen schematic, the pinout of the edge connectors of the gameboard is different than Alive. This would mean that the Aspen and Alive gameboards should not and do not interchange. Aspen has a 3 bar chimebox (looks like a Williams chimebox assembly) installed for sounds whereas Alive generates electronic sounds (no chimebox) and has a speaker. The date on the Aspen manual says October 1977 so it actually came out a full year before Alive did.

There are two versions of Aspen. There is the first version with a model number 55-860200-2 which uses a 3 bar chimebox for sounds. This model was made in October 1977. The second version is model number 55-860228-2 and uses electronic sounds and a speaker. This model was made in October 1978 a full year after the first version. The second version uses the exact same gameboard and wiring as Alive. The two Aspen versions are wired completely different than each other and the gameboards are NOT interchangeable.

Manuals for both versions have now been scanned and are available here:

Thank you! I just picked up an Aspen for a project and I used the manuals to see what I was getting into before picking it up. Much appreciated!

Just as a follow up, thank you Ken. Your documentation has been indispensable. I finally repaired the power supply today (got 28v back by replacing the BR) so now it is flipping, and a while back my students and I built/wrote an Arduino-based switch matrix that detects closures.

Not bad for a headless/lose wires project that was $75!

Glad you were able to get it operational again.

Good news for Brunswick/Briarwood/Mali home model pinball machine owners. Pinball Life is now stocking parts for these machines.

And of course if you need manuals or schematics or repair information, Pinwiki has quite a bit now:

OK -- none of the manuals have schematics and the drawings listed as 'schematics' are actually the machine's connection diagram.
Seems that nobody has the schematics for the main board in these.

Anybody want to temporarily donate a CPU board so the schematics can be drawn?

Yes, that would be nice if someone could loan Ed a main cpu for him to reverse engineer some schematics and get photos of the boards.

Thanks to yender0 - I have a very clean looking Brunswick board sitting on my bench. I'll start drawing up schematics this weekend.

Be sure to make note of any pc board numbers or revision numbers on the board.
