What about this ASTEROCK in the end? I'm curious

As mentioned in a previous post, you need 23v DC unregulated to trigger the
inputs 5v won't do it.. 12v just about does it, but I'm using the proper
23vdc for the inputs...

The schems and wiring diagram are scanned and online, you'll see how it's
wired on there, I have it all correct...

I might just end up sending the Pcb back to the owner to try in his cab, but
there is no reason this shouldn't be working on the bench the way I have it
wired, hence my post...

Sidam also uses this wacky 23v for inputs on Explorer and Missile Storm.. I
haven't looked at my Sidam centipede, but I bet that does too, those wacky
Italians.

Hey I happen to own a working Asterock :)

I remember that this has puzzled Andreas who fixed my Asterock boardset too.
He repaired it up to working attract mode but couldn't coin it up whatever
he tried. In the end, he just shipped it back to me in the hope that it
would just work in the cabinet. Which it indeed did, and still does.....

The inputs of Asterock expect a +5V instead of a shorting to the GND !!
However, we knew this but still Andreas couldn't credit it when he shorted
+5V to the inputs.........

I never investigated it further because well....it works in the cab....:)

I do assume you have the schematics ?

Yes indeed, all roms verify with the ones in Mame. Verified in-circuit with
crc32's.

Andy,

Have you verified your roms/eproms ?

All inputs operate properly, slam, diag step, test, hyper, rot left, rot
right, thrust fire, start1, start2.. Each one beeps as an input in test
mode, as well as reads properly at its correct address through the cpu
socket (on my fluke) none are stuck...
