FPGA board with an adapter to fix an The original soundboard is basically just a hooked up to an 8-bit DAC for making audio effects Time for some crazy home PCB etching Soldering these things is a bit tougher than a DIP package tho'.

Results came out very well for a double sided prototyping kit etch with10mil features. The result is a PQFP bare board. Received my ROMs boards back from the fabricators, so a quick picture showing the original and the repro-boards. ROM pcb comparison - Original and Repros. Update on the next piece of my WMS projects. Some pics of the proto board that's been under test. A Williams soundboard like no other.

Harris provided some very useful application notes which makes writing a software implementation go more smoothly. A new year.. I'm still messing with Williams gameboard hardware, which is really fun. You can't play too much Defender or Robotron. The Motorola was a great CPU and it interfaces nicely with Xilinx parts, a strange marriage of 's and 21st century parts. The original used a Peripheral Interface Adapter, with some additional logics.

The design goal was to build a functional replacement that implemented just enough of the in a Xilinx CPLD to make it work. More stuff for Rampart! This is a Atari custom optical encoder interface, for use with trackballs, spinners and to quote the off-the-wall manual, a 'Whirly-Gig'.

It's used on both the joystick and trackball version of Rampart. About a year ago I reversed the logic for one of the SPLD simple programmable logic device for an Atari Rampart board that was missing the part. As a follow up I recently had a request for help with replacing two other GALs on the board. After some quality time with an analyzer here are working replacements for the part , and Follow this link for details on the updated Rampart replacement GALs page.

Well this should have been the June update! So I got ahold of clone Pengo boardset that was missing the 25LS, not exactly a common part to find, so it was time to build a replacement. Note: This also works on an original Pengo boardset. Ready at last.. This probably should have been the march update! April was the 25th anniversary of the awesome old 8-bit computer the Sinclair ZX-Spectrum so what better time to publish details of a for-fun project. My version of an AT-keyboard interface to the zx-speccy, full source, schematics and PCB layout provided.

There are some more fun speccy projects I should get around to documenting one day too March was spent driving across these states, not ALL of the month, but some of it So apart from being a really excellent thing to do for the emulation of these games, having the original ROM available helps me complete the long procrastinated replacement for the 54xx. A high score save project completed!! First one in ages it seems and it's for a good game too! Do's Castle high-score saver! Patches and details for the 3 different versions of the game.

High Score Saver for Mr. Do's Castle! Added a new page with the wiring diagrams and mounting templates for both the v3 and v4 encoders.

Also the dimensions and wiring for the panel mount s-video and phono connectors, along with how to hook up panel the mounts for the both the encoders. Travis Brown at RetroBlast has completed a review of my component encoder. PCB's for the sync-cleaner boards arrived. Made a few up for testing and all is working as expected. They'll help clean up the video sync for games like Golden Tee 2K which can have real problems with some TV's.

It's designed to help with the compatibility between games and TV. Pics of a sync cleaner. Video sync-cleaner. First pics of my Random Scan, aka, XY vector monitor, complete with fully custom wound yoke!

Random Scan XY Monitor conversion and a little yoke winding. I'm now looking for a higher resolution tube, that one is 0. The 03xx CUS03 custom IC as I had no idea what the thing did apart from it was something to do with the scroll function. Results of a few hours analysis. Expect that soon Cleaning up the site again.. Need to add some project pages too after playing with old ZX-speccy stuff.

Manic Miner is still a wickedly good game even after 20 odd years. This was the custom micro-controller used on Pacland, Skykid, Rolling Thunder and on the later system 1 games. So after some messing around with 's here's a new page dedicated to the CUS60, 63 and Include schematics for a replacement board, code patches and the source code.

The CUS60 micro-controller an owners guide Wow.. Who knows I might actually complete my ZX-speccy clone sometime in the next week as well. Finished the build of the new v4. I hope I've not missed replying to anyone who's enquired about encoders during this short interruption of normal service Golden Tee Fore seems to be becoming ever more popular as the prices for the boardsets decline.

So I've been looking into the sync issues that affect some TV's when you run the boardsets with a video encoder. As things just can't be simple, testing has found that some TV's have been fine, others have rolled vertically and some have just freaked out in very funky ways. Under test at this very moment is a new sync-cleaner that should resolve the common problems.

Except for TV's that just flat out reject anything other than a perfect 60Hz vertical sync. It's a small 1" x 1. It 'cleans up' the sync output from a game to the standard durations of the NTSC specification. It's not restricted to Golden Tee but will also work with other games that can have problems with some TV's, for example Primal Rage. Busy building more component encoders, email for pricing and availablility!

More details on them over the next few days. Wiring diagram and mounting templates to follow. As a few folks have asked ALL models the v3 and v4 encoders are available without the phono and s-video connectors to aid in panel mounting. Pics of a special project I didn't put up before The worlds smallest encoder? A micro-NTSC encoder for the times when space is really at a premium, slated for a small production run if there is much interest. As much of a project in how small is too small to build?!

The RGB to component encoders are now available! After several requests I'm adding a lower cost component only version of the encoder.

Click here to see the new encoders. One quick picture of next arcade product an RGB to video, s-video and component encoder. Click here to see the first production boards. Pin headers for all outputs, RGB pass through and it'll also be available in component video only form, if you don't need any of the other video outputs.

I've finished a pretty big Oracle Apps implementation project which has absolutely nothing to do with Arcade stuff or games in general but has been taking up large parts of my life for the last 4 months or more.. But it's done, in production and working as well as Oracle apps Now several thousand lines of customized code are done it's back to doing some updates to the site What happened to June?

I think it evaporated. Time to get back to work on projects. Yet another distraction!!! Trying to keep my target of at least a monthly update!
