New Portable

[JackFrost22]

Since my snes v2 is fried my only snes and i have what 20 games i wanna do something else with my psone screen. That is if I can get all the hot glue off. Well anyway I wanna build a portable thats new and original. I tohught maybe atari 5200 no wait a poll thats the answer

Well one you think the PSOne screen will work with these systems, it isnt exacly friendly with the Atari. And what in the world is "Channel F"?! Never heard of it. I will say that as Ben has not made fun and there seems to be more games for it, go with the Colecovision

[SpongeBuell]

I was the first to vote and the first to say colecovision. AFAIK, the games weren't that great on the intelly or Channel F. The Channel F was (I believe) the first video game system to use a cartridge. Not very common, though. If you fry it, that's not good.

[SgtBowhack]

Yeah, don't fry the Channel F! Colecovisions are a lot of fun. I'd say go with that.
Sparkfist: SpongeBuell is right about the Channel F being the first to use cartridges. See this page for more info

Yea, Channel F was the first cart-based system, but that's about all it has going for it. It sucks, and it isn't any fun, except for the novelty of owning a piece of (obscure as hell) history.

It sounds like with today's technology it'd be trivial to make your own teeny tiny Channel F. The main processor wasn't even a processor, it was just an ALU. With the MESS source code in hand, one could probably figure out how to make a Channel F in VHDL in a matter of hours. Then you just put all of the ROMs together and you'd be set With its limited palette and resolution you'd be almost better off wiring up some multicolor LEDs for the display

I have 2 channel fs thats wh i put it down. The only problem i forsee with the ColecoVision is that the controller is wiered. It works off 7 volts negative

The Fairchild Channel F is a 1975 console which was the first cartridge-based unit(the first "programmable console").

Though the Inty is 120 VAC in, I have looked at the guts a fried Inty board and it looks like it uses 12V and 5V. The power board is also fairly large, meaning the Inty can likely be shrunk(I am reffering to the Inty Type-I).

I have never seen or used a Colleco vision, but since it looks like an Inty-I on the outside, I can imagine that there may be similarities internally. I could be wrong though, as that is just a guess.

Then run 7V in, wire the controller's GND to +7V and the controller's -7V to GND. It should work fine.

There may be a negative voltage regulator on board, but unless you can reverse EVERYTHING to work on 7 Volts instead of -7V (which is possible by swapping the GND and the Vcc) I would not try to swap it out with a positive one.

Then again, you can always leave all the connections as-is, take the negative regulator out, and put a positive one in, switching the middle and right leads(looking at the front of the regulator). That may be the best solution.

or more likely you'll need to build a negative voltage generator out of a 555.

Negative Voltage regulators are out there. I believe they are labeled 79XX instead of 78XX....

I remember seeing quite a few 7912 and 7905 units in AT and BabyAT-style computer power supplies.

A colecovision is a lot smaller that an intv 1. I openened mine up it s about the size of a a genny 1 or an nes
