Looking for the front plexi. This would be the 44" version. Repro's are out there but sadly not this length. Let me know what your have. Thanks. Clive

If anyone has U10 sound ROM file or a ROM for an Ice Ball Skeeball revision 2 main board, please contact me. Happy to pay for either. Thanks, Clive

I'm curious where the amplifiers came from since they have been obsolete for some time and it's the main reason my shop stop repairing them. The amp's on Ebay are fakes and explode in quite spectacular fashion (ask me how I know). This game does generally have high background noise that wouldn't...

I really don't understand what you're trying to say here. We had a stock room full of chips and hundreds if not thousands of POKEYs back in the day, you have no idea what I saw or what the actual failure rate of POKEYs was (we did). Very odd statement. Clive

I own and run the Coin-Op Cauldron. I'm in the US but ex-Atari UK with 30,000 board repairs under my belt but most of those are pinball related but that's another story. I've seen plenty of Atari boards over the years, there are probably 30 in the shop right now. I don't repair Atari boards for...

I've never seen a POKEY in this form especially as late as 1980. I have AMI 6820 PIAs and 6810 RAM in this form factor from 1977. It's possible that due to the high chip demand of the early 1980s that the Korean plant may have had to fire up an old line to meet production requirements hence your...

No problem. The printer used in The Addams Generator was an standard EPSON M260 or M260-A, the latter had an auto-cutter for the paper but I can't recall if it (the cutter) was implemented in software. The bigger problem was the interface that sat between the CPU board and the printer, it was...

I've repaired quite few of these boards boards in the past and your CPU board is the cleanest I've even seen. (I no longer do repairs or support this game because of the obsolete parts... amps, custom Actel CPLD etc.) Clive

Fix the ROM problems first, ignore the diag LEDs until you have working ROMs since the system is reporting POST errors. Checksum the ROM(s), check for open address, data and chip select lines to the ROM socket (assuming the socket itself is good) and if that fails, start checking the chip...

Both the 160 and 322 are 16-bit ROMs the difference is that they vary in storage size. The 160 is 1Mbit x 16 (but can be configured for 2Mbit x 8 but ignore this) and the 322 is 2Mbit x 16. You should cover exposed windows on these ROMs from bright light as this may cause a possible charge to...

Heat is the biggest enemy of silicon chips. Thermal expansion and contraction is another physical issue that causes issues with chip dies. There are some chips manufacturers that have issues with fabrication... AMI is the one that instantly comes to mind. Many an AMI chip has died due to age...

It is indeed just a 0.01uf bypass cap.

Looking for Dezbaz's 13" reproduction vector monitor PCB for the PAT 9000. Drop me a DM with price. Thanks, Clive

The trackball connects to connector 4 on the left side but you need to set DIP switch #1 to 'on' located on the joystick interface board. Clive
