Oh, man. Really could use one of these, I've had dead customs in my Gorf for years. :(

Long time no post! Throttle gear blew up in my #1 Hydro Thunder, so rather than drop $30 on a new one with the same physical design problem, I designed a replacement part and printed it. I've put the files out for free over on Thingiverse: https://www.thingiverse.com/thing:6874028

Ed has always been a huge resource and a class act. Sorry for your loss, man.

One of the greats. Rest in peace, Ken.

Going to mirror lilypad19, get the Shoestring test rom. It's pretty robust and will even spit out some graphical error codes when the board won't fully boot.

Some CF Cards correctly identify the IDE Transfer modes they support, some don't. This is why I like using the IDE Disk-on-module/SSD's instead as they have explicit support for correctly identifying themselves.

Hey all. In the market for a Stern Ghostbusters Pro in the Chicagoland-Milwaukee corridor. Let me know what you've got.

Likely a bad HDD. Good time to swap to a CF Card or Flash Disk-on-module.

Exotica U3 should be 27C322 (4096kb). You'll have to use something like HJSplit or Goetz File Splitter (now free - http://www.lawrencegoetz.com/programs/gfsplit.htm) to bust up the ROM into sequential parts.

I pulled a copy of the Fujitsu MB8516 datasheet. Says (in Japanese) it's an equivalent to Intel 2716, so yep, that would be correct, any regular (non-TMS2716) will work here. The link from Marcos is all regular 2716-equivalent parts. Should be the same size.

Crack in the flyback or bad dag ground.

Check AC line voltage - could be a bad back door interlock. Actually ran into this very same sort of issue years ago on my Missile Command.

Greed & tax evasion.

It's horrible in the Chicago area. I hope it tanks, hard.

Everything except U99 (PGA decoding custom) and U34 (TMS34010 CPU). These are universal.

Hey all. Ran into a Smash TV board with a shot U99, so I picked up a High Impact to turn into Smash TV. Found some interesting stuff. Both boards sported a few post-manufacture wire bodges, which were actually required to get the games working. First up: Smash TV Wire 1 - U67p16 (-LCAS) to...

I've got a Tek 2465B, the last of the Analog Cadillac's. Great scopes, just keep an eye on the cooling fan.

Looking at this again, it seems to be able to read from the 4 Background ROM's correctly, but it's getting the wrong data sometimes. I'm thinking it's whatever drives A13 on the EPROM's for banking, but the schematic is completely missing whatever drives that circuit (BKA13). If you follow it...

U74 (74LS283) encoder would be my next bet, then U58/U59 which drive them, a 74LS175 and 74LS374.

I have one that works except B+ adjust. Even though it works, I'm always tempted to do this.
