@SeanKelly These reproductions look great! Will these be available again in your shop this year?

[Magnavox Odyssey Multicard - call for orders!]

Hi! Signing up for one as well! 🙂

 

EDIT: Payment sent.

[New Coleco RGB board?]

Really cool to see this progress! 👏 I will take 2 (1 PAL and 1 NTSC) as well!

[Casio PV-1000]

The 80 Euro thing is just the box, and the other 3 Ebay offers are fake (all use the same pictures with different accounts etc.) 😕

[Casio PV-1000]

Looking for a Casio PV-1000 Console.

[Fairchild Channel F burned power supply]

To add to the second question: If the -5V is needed, can I replace the entire internal power supply circuit with input from a -5V, 5V, 12V power supply likes this (Mean Well GP25A13A-R1B) ?

[Fairchild Channel F burned power supply]

I'm thinking about replacing the original power supply with a switching one directly connected to the DC lines, as described above. Questions that came up by looking at the schematics of the model 1 (see bottom left corner of this schematic):

• Can i connect the power supply directly to the output of each voltage regulator, or do I have to remove them to avoid strange behavior of the ac/dc circuitry that would get current in the other direction (some kind of back-flow)?
• What about the negative voltage (-5V) for the RAM that is at the bottom of the power supply schematic, does it suffice to give the +12V and +5v to the voltage regulators output pins, or do I have to construct some kind of -5V supply for that point as well?

[Building a G7400 RGB cable]

Ok, thanks for the explanation, this makes it much clearer, esp. with the picture.

So the original socket (the one used in the french versions of the G7400 is a circular one and not a horseshoe as described in the RGB mod page? I want to create a mod that is close to the original french model, so I would like to know whether I should order a new socket for the pcb or a connector for the cable.

[Building a G7400 RGB cable]

Reviving this old thread:

What 8pin DIN connector did you use for the cable? And does the connector differ from the one used in the older G7XXX ?

I bought all components for the RGB mod as described on the site you linked above, including the correct MAB-8-SH socket. I then ordered this Odyssey/Videopac rgb cable. Before doing the RGB mod I now realized that the cable connector does not fit in the DIN socket, it must be this other DIN 8 variation mentioned in the mod manual.

 

I have some spare DIN-8 connectors, but those also seem to be the wrong kind, hence I hope someone here can give me a link or article number of a connector that fits into this special MAB-8-SH DIN 8 socket.

 

Thanks
