Dreamcast and Mame cabinet
<< < (5/10) > >>
Miller:
The cabinet is a Naomi universal but the wiring has been made by me so a schematic would be useless really , your PDF file was correct with the Dreamcast and I-Pac PC both supplying an independant 5V source just the Dreamcast pad seems to nick the PC source  :'(. I am going to have a mess around with it tomorrow and see if i can split the original wires from the controls into two and see what that does. I will let you know how i get on and thanks for the help much appreciated.
NickG:
If your Dreamcast is working fine even with the Ipac connected, but not the other way around, then you could employ a SPST solid state relay per input line, which will break contacts with the Dreamcast collectors when you wish to have your IPAC function.  You can get these with five volt coils which could be wired to your PC. How exciting!  If you wish to get even fancier or cheaper you could use some 4066 or 4016 switches.  In fact, these are of  what some jamma switchers and A/V switchers are comprised  These can also easily be configured into a [make PC - break DC]  / [make DC -break PC] configuration.  I don't quite understand how a voltage regulator would help in this situation; a schematic would really help there.  Old fashioned diode blocking might work though - not sure.     
moloch:
I only suggested the voltage regulator if you are going to add voltage to the line, that way you insure that you do not exceed 5v.
NickG:
Oh! it finally snapped; I get it now, thanks.

Is there a point to all this messing around, when you can just have a switch box?   ::)
