Ultimate Coffee Table Part#2
FYI - I'm covering ground here that has already occured. I will do my best to make sure I haven't missed too much that we've already covered.
So lets have a look at our coffee table.
It's hideous to say the least. However ideal for our project. With 3 compartments we can seperate our units and also have a storage area for the cartridge games.
Off we go to the local hardware store and score some MDF. One 9mmx2400x1200 sheet. So quickly chop it up to size. Rear sides and top are sheeted. We're looking for a modern, fully faced coffee table. This will allow for front side loading of carts directly into the UCT (Ultimate Coffee Table).
Basic sheeting completed. We've got some shocking gaps but nothing so serious we can't fill them out.
Yay for filler. Front sheets are not going on. And probably won't for a while as we've got a lot of work to do to nut out how we're mounting the consoles. We are planning on using one compartment (a far side) to have all the consoles inside. With a hinged door to we can get inside should we need too.
Console Discovery.
What do we already know.
Atari 2600.
This is going to be the easiest unit. The controller is very simple. All buttons are activate by short to common.
NES
IC Controlled controller. 5 pin. The IC used is TC4021BP made by Toshiba.
RF and RCA outputs. We plan on using the RCA for easier switching.
SNES
IC Controlled controller. 7 pin. The IC used is V520B made by Motorola.
RF Out. There is a 'Multi Out' which we are pretty sure we can directly map to RCA out for video and sound. Too easy!
We are of the belief given the remarkably similar design of the two Nintendo controllers that we may be able to use the SNES IC to control both controllers.
So we know we have a binary activated controller whose buttons are conductive activated. This is going to make mapping quite a bit more difficult for the relay design we have planned to share the controllers between units. This is Daves area of 'know how' and I'll let him post up what we've got so far.
At the very moment we're working out auto power on switching for the consoles. We've stripped a SNES apart and have nutted out the basic circuit for power (short). We plan on using a momentary switch beside the cartridge rail so that instead of having a seperate power button for each console, we can activate the power by just inserting a cartridge into the unit. Progress was slowed by a dud SNES which despite showing 16v DC when shorted would not actually turn on. Stupid bloody thing.
