If the chips are socketed you might try to pry them a bit out of the socket and press them in again, might do the trick.

www.videopac.co.uk expires 9th March 2018, I'm not going to renew it so there is a window of opportunity for someone to grab it.

Hello, I am about ready to release a game, my first for the Channel F, called "Kevin Vs. Tomatoes." There will be 18 copies for sale. Each will come with a game cartridge and instructions sheet. See more info on the game at http://www.atari2600land.com/killersnakes/. E-mail me at atati2600land[at]yahoo.com if you express interest in getting a copy. Thanks.

I can't help you with the technical side of this story but I do notice that the character colors on your Select Game screen are different than the standard colors. Might be just the photo but I'll post an image for comparison just in case.

Let's have a look inside Smiley.

Do you know if most the G7400 pcbs have their main chips mounted on sockets ? Does this PCB look standard to you ?

As I said, it doesn't work : when I put a cartridge and turn it on, I get garbage and glitches on the screen, sometimes some sound effects. If I press the RESET key, I get the "Game Select" invitation screen, but corrupted.

If you look at the letter I get, you will notice it is written "WELEGT GEME" Smiley.

Let's have a look at binary coded ASCII table for the impacted letters :

S = 01010011
W = 01010111

A = 01000001
E = 01000101

C = 01000011
G = 01000111


Have you noticed the same thing as I noticed ? Smiley

The third bit from the right, D2, is always set to 1 on my machine, even when it should be set to 0 !...

I need to look at the data bus and find wich component is defective, forcing the data bit D2 to a high level. If you have any clue, it would be very welcome Kiss.

Bye

Hi,

Here are some of the cartridges I got with the console.

As you can see, many of them were opened and somebody hand-wrote extra numbers on the label.

Welcome to the forum  Smiley

I'm already curious about the cartridges. Did you try them on your other VPs?
Looking forward to their content and looking

Hi guys,

I attached more pictures of my unusual JoPac (sorry for the low quality pictures, I took them yesterday with my phone in my storage room where light is not good...).

I first noticed this unusal switch under the console. I opened it and it revealed to be simply the power switch because the original one is missing (broken I imagine).

As I said before, there's absolutely no name, brand or product reference on it ! Because I'm not a Videopac expert, I discovered only very recently that it was a JoPac Smiley.

The nice thing is it features an RGB output with a SCART cable Smiley.

This evening I brought it back home, so I will be able to look closer at it, and will start to repair it. On the next post I'm gonna show you some of the cartridges and the inside, and the defect Wink.

Bye

Hi guys,

Thank you very much for your kind words  Kiss.

Yes, I'm gonna open another subject for its restauration Smiley.

I also noticed the keyboard overlay is not the one supposed to be present on a JoPac, but the one from a Videopac. Considering where I found it, with many non official cartridges, I'm wondering if this JoPac could be some kind of prototype or a preproduction sample unit...

I'm gonna submit more pictures to your expert eyes ! Wink

See you soon.
