Re: Expansion Pak Relocation Problems

Can't see any problems from the pics, it appears to be a good soldering job. Maybe get out a magnifying glass and examine every connection? You can try running a toothpick between each solder point, sometimes this will remove small solder bridges without damaging the board. I built a portable N64 an...

Re: SOPA: Yes or No?

SOPA is dead, but will surely return later in a "less severe" version. The funny thing is nobody outside of the music/movie industry wants this or anything similar passed. They have near unlimited funds and are always pushing this sort of crap on lawmakers. If such an organization has enough money t...

Re: vac formed case woes

I would draw a line around the perimeter with a straightedge at the maximum depth.
Then rough cut with a tin snips not quite to the line.
Finish by using a file and/or a sheet of sandpaper on a flat surface. Be careful, the plastic around the corners is thin and prone to cracking.

Re: Which consoles haven't been portablized?

I know for a fact these systems haven't been portablized, along with the best reason I could come up with. Magnavox Odyssey: Is not fun to play. Try carrying poker chips, cards, dice, overlays around. Magnavox Odyssey 2: Has that stupid membrane keyboard, also bad games. RCA Studio 2: Few available ...

Re: Sega Game Gear Stereo Speaker Mod?

I'm sure a stereo speaker mod can certainly be done with the Game Gear since it has some extra room internally for another speaker. You could connect the speakers to the headphone jack, but the volume would be too low. Headphone jacks normally don't output enough wattage to drive a speaker to a dece...

Re: Any N64 Portables for sale?

I have a semi-portable N64 I would sell for $150. It's not a handheld portable, but more like the PSOne system with screen (same screen actually.) It's much smaller than a regular N64 and can use any 12v supply. It just looks kinda rough, but is well built and works great. If you're interested PM me...

Re: Atari 5200 s-video mod and digital controller interface

I've been selling assembled and unassembled s-video mod boards for a couple months now and feedback has been positive. There's 2 versions, 1.2 which is cheaper and more basic, and v2.0 which completely replaces the Atari's video circuit. After selling 3 prototypes of my 5200 digital controller inter...

Re: NES lockout chip damaged

You can use the lockout chip from any cart. They have different numbers, but are functionally the same. It's best to ground pin 4 if possible.

Atari 5200 s-video mod and digital controller interface

I built an Atari 5200 s-video mod circuit by following this faq: http://www.atariage.com/5200/faq.html?SystemID=5200" onclick="window.open(this.href);return false; I tested the modified Atari on a 20" CRT TV, it looked pretty good so I thought I'd sell it. It sold for $100 on ebay. I thought I shoul...

Re: NES mod questions (power and regulation, cartridge slot etc)

The digi key cart connector (A31721-nd) isn't exactly the same pitch as the original, but it's so close I found it to work just fine. Also, you don't need to duplicate the original composite boost circuit, a 2n4401 transistor and a couple resistors works well also. I used a adjustable voltage regula...

Re: FS: arcade pcbs, laptop parts, lots of other stuff

I would be willing to trade, if it's something I don't already have 5 of, lol. I am looking for a working dreamcast system. I'm also looking for accessories for vectrex, bally astrocade, colcecovision, etc. PM me with anything you'd like to offer for trade.

Updated with new items (again.)

Bally Astrocade repair attempt. Has power issue.

I recently purchased a non-working Bally Home Library Computer / Professional Arcade / Astrocade system. On power up it would only show a black screen. I found that the original power transformer had no voltage output, so I'm going to start there. It's a really odd transformer with 2 center taps (4 ...

Re: Metallica Man's Comission Projekt!

Did you disable the lockout chip? I didn't see that done in the pics. Otherwise your solder connections look good. There's 10 pins in the middle that don't need to be connected, they go to the expansion slot. I did a NES cart slot relocation using digi key part # A31721-ND and it seemed to work well...

Re: RBG a jaguar to ps1 screen question

After looking at the Jaguar AV pinout, it seems it has separate horizontal and vertical sync. I'm not sure if that's for VGA or what. I would forget about those and wire up a LM1881 sync stripper circuit to Jaguar's composite video output pin. Connect the circuit's composite sync output to your PS1 ...
