IC Region Chips for TG16/PCE/DUO's $17 shipped

He hasn't responded to emails or anything. I've redrawn an IC schematic to have some made.... the cheapest cost per unit is around $2 each (no ICs, just the board) and that's buying 66 of them for something like $116 shipped. I've held off ordering them for two reasons though... one the 4551 ICs seem to be a little troublesome to locate at the moment, and two because thesteve has designed a better single IC design that can also be made switchless if desired. I'm thinking I may draw up that design instead. I'll let everyone know when it happens though!

I'll take 2!

I'm also looking to pick one up once you get them made

I've got a Turbo and CoreGrafx, but it'd be nice to consolidate.

woah, switchless? How does that work?

It involves holding a button like select while powering on. This is nice for the turbo express but maybe not so much on a console. This same design can use a switch also.

Any word one the boards? I would take 2.

BlueBMW · 06/16/2011, 06:38 PM

Havent got them produced yet, I'm still finalizing a design. I'm trying to make one small enough to fit right by the hucard connector on a turbo express. I'll update when I have more info!

Will the boards work in any tg/pce? If so they would be great for a core grafx so you wouldn't have to drill any holes. I'd be interested in picking one up when there ready.

I was thinking that all the way through, glad you figured it out!

Thesteve came up with the design. Im just working on getting them made

the switchless works well on the express, because i can connect directly to the controller board.
it could be used on the duo based on the cd door switch.
other consoles will need a switch, or button added to control it, but it can be a very small button (single contact momentary)
it can also be controlled with the same switch as the old chip design.
