Hello faithful readers,
Back again, this time with some new tools to play with.
I have to start off by raving about the NeoLoch LLC Inquisitor board and SRAM blade. The Inquisitor board is a platform for IC testing and more, and the blades add compatibility to specific families. The SRAM blade does all the common SRAM I've come across, such as 2114, 6264, 62256, 2147, 2148.. nicely this includes the 4-bit SRAM that most EPROM writers don't bother to include compatibility for. In general, I've found that my Topmax 3100 EPROM writer doesn't do a good job of testing SRAM at all, since all it allows you to do is write a specific set of data to the SRAM and read it back. Anyway, I bought the unassembled combo, and had it up and running in about half an hour.
Let's take a look at this bootleg Ghosts 'N Goblins.

Hello true believers,
I originally had this Legendary Wings marked "working". Thought I'd give it a few rounds of play time, and listen to some of that beautiful Capcom arcade soundtrack. Check it out:

So I fire it up, and... I'm not impressed. The music sounds a little thinner than I remember. I loaded the ROM up in MAME to compare and yes indeed, it actually sounds like the board is missing about half the instruments. My eyes turned to the sound section of the PCB and behold, the reason it only had half of the sounds:

Hello friends, on to another repair log.
Here we have a Suzuka 8 Hours 2 board, which is a classic motorcycle game from 1993.

Hello again faithful readers. Today, I'm detailing the creation of my newest atrocity, Super Mario All-Stars NES.
I'm cramming the data of 4 games onto 8 Mbit EPROM chips and using a binary counter to cycle through the games by pressing the console's reset button.
Don't care about the technical details? Click here to see the final result in action.

Hello again folks!
Today I want to cover a very common fault with the Colecovision - their power switches. Basically, they are very mechanical in nature, and easily get dirty and cease to work. Often this means you'll get a picture on your TV, but it may be totally scrambled, or just black, or whatever. Most people would never suspect the power switch but it's easily the most common Colecovision repair job you'll see.
First things first, if you just want to repair your switch, it's pretty simple too. Just follow along, you'll see what to do.
