What's New & Happening

Last Update Aug 26nd 2003

Aug 26 8th : Some Pics.

One of the custom IC replacement PCB's custom_cpld.jpg

Time Pilot Hi-Score save board Time Pilot HSS  - aparently... a lot of the boards do not have socketed Z80's which really makes things a pain if you have to desolder and add a socket before you can plug it in !!!

Aug 23rd : Project Updates (!)

Custom IC replacement PCB's are in, just need to build a few. Compatible ICs for the early vintage Midway board will be the 00xx, 02xx,  04xx, 06xx, 07xx and 08xx. Still working on some of the others (!)

08xx and 05xx starfield generators are already available from Arcadeshop:

Finishing off some hi-score save projects which have been in limbo forever, Timepilot with a complete plug in PCB has tested out ok. Should be available very very soon. Pic's tomorrow.

July 8th : RGB encoders back in stock & Shipping.

Lots & lots more encoders in stock. Available for immediate shipping.   Pictures & Details...

New obsolete datasheets scanned, Mostek MK4096 DRAM. Antique Datasheets...

Mar 23rd : Farscape ends....

A totally different subject...the Sci-Fi channel aired the final episode of Farscape this weekend, a show which really didn't suck. They seem to be obsessed with canceling anything that was actually good. Anyway.. fans of the show are rallying to support the show and encourage the corporate all-knowing to change their minds so it can stick around for another run.  Info can be found here..

Mar 9th : Some new Datasheets added....

Added a few more old parts, 4027 DRAM, 4116 DRAM and 4801/4118 SRAM.
Also FINALLY found a sheet on the old ER-2055 EAROM that was used on a number of early Atari games to store the high-score table. Antique Datasheets

Feb 25th : Nothing Much Really....

Big batch of RGB encoders built !!! Lots of RGB encoders Order now before the xmas rush ! 

Updated the Arcade page and added a link to some old SRAM and EPROM datasheets I've collected.  Antique Datasheets

Got some new projects/products almost very very very close to being completed, they're in the final stages of testing and I'd really like to get them done soon. Perhaps a product release before March (!!!)

 Quick picture of one part, replacement 07xx custom IC on a dig dug PCB  07xx  on DigDug CPU board the flying wires are just for a test header and theatrical effect.

Apparently... I need to fix the links page again and add the scans of Bosconian schematics, which I'm sure someone had done before, but I can't find them anywhere.

That's all for now...

Dec 17th : Finally an Update !  It must the Christmas !!

What have I been doing ?

RGB encoders - new boards are in and they look GREAT.  Even better 
than the last ones ! New pictures coming soon as I take some decent ones.

Finishing off some of the custom IC projects I've let drag on all year...
Who knows some parts might actually get released (!)

Williams Joust/Robo/Sinistar "special chip 1" work in progress, of course I had to pick an expensive part to use (!) so this might just be a fun 'how it works' project.

Modifying a Gamevue Playstation panel to run standard RGB input, this was to make a super portable RGB monitor for testing game boards.
Here are the details of the modifications -> LCD Panel fun !

July 18th : RGB Encoders & More !

RGB to NTSC Video Encoders  - Click to view !

They're now are available follow this for pictures & details...

In other news I am working on some replacement custom IC's, for the repair of Galaga and other assorted game boards. It's comming along nicely, the replacement starfield plug in board is in production and will be released shortly. Here's one of them !

Here's a pic of a superpac board with one of my replacement parts undergoing some testing

It seems to have been a busy year as it's July already (!) what happened to May ???

Feb 13th : Fun with micro-controllers & page updates ( someday )

Wow... haven't updated the site in a while. Been having way to much fun playing with Atmel AVR micro-controlers !
Eventually... I'll get around to putting some more pics of bootleg boards seeing as I've picked up a whole lot of really interesting ones ( interesting for me anyway ). There'll also be some pics of my work on re-engineering some very old, very obselete custom ICs from game boards.

All the old news from years past is here !!
