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
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 &
New obsolete datasheets scanned, Mostek MK4096 DRAM. Antique
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.
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
than the last ones ! New pictures coming soon as I take some decent
Finishing off some of the custom IC projects I've let drag on all
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
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 http://www.jrok.com/hardware/customic/
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
