Duramold Sinistar

Here are some comparison photos of two Duramold Sinistars. Mine is the one on the left. Matt's is on the right with the Blaster joystick. His must have been more of a prototype. My Duramold has serial number 624398. That is higher than the S/N for any of the wooden upright and cockpit versions, which means it was probably built after all other versions were released. It also has the Revision 3 ROM set with the final numbers, which further indicates it was built at the end of the run. There are only two complete and two partial Duramold Sinistars known to exist.

I live in Westminster, CO, which is a suburb of Denver. If you are in the Denver area and want to stop by to check out my Duramold Sinistar, let me know.

If you are wondering, these Duramold Sinistars the actual games manufactured by Williams. They are not just a converted Blaster duramold. You can see that Blaster has two speaker holes and the Sinistars have one. It would be difficult to get rid of the hole if it was a Blaster conversion. Matt's Duramold Sinistar has the Blaster joystick, but that is probably because it was an early prototype. The Duramold Sinistar also differs by having different monitor bezel artwork, control panel artwork, and a different sized marquee. It looks like the wooden upright had at least two different marquees. The one in the picture has a blue background similar to the Duramold, and mine has an all black background.

Sinistar Duramold Q&A:

Q: Differences between Duramold parts and the wooden upright and Cockpit.

A: See the chart below

Part Duramold Part# Upright Part# Cockpit Part#
Marquee 31-1133-3004-UP-P 31-1056-3004-U-AP ?
Monitor Bezel 31-1134-3004-UP 31-1047-3004-U-AP ?
Control Panel Overlay 31-1132-3004-UP-P 31-1042-3004-U-AP ?

Q: Was there a Red Duramold Sinistar?

A: Probably not. Here is a quote from Williams Arcade Classics: "Sinistar also had a small number (under 500) of games in cylindrical black cabinets." 

I have been told about one other Duramold Sinistar.   From what I have been told, it is in a black cabinet also, but has a blaster joystick, which would make it an earlier prototype than mine.   That, or it could be a converted Blaster, but the person that I talked to said that it wasn't.  If you know of another Duramold Sinistar, please contact me. I am interested in finding out if there are others.  They are much more durable than the wooden versions, so if there are some more, I am sure that they have not been destroyed yet.  (UPDATE 9/22/2003: This machine was purchased by Matt who created a site for it at (dead link))

I found someone else who said that they had played one when it came out.  They played it in Lexinton, KY, and it was a black Duramold.   Still no validation on the rumors of a red Duramold.

Q: What are the differences between the Blaster, Bubbles, and Sinistar Duramold cabinets?

Duramold texture Texture is smoother. Came from a different mold. Same as Sinistar Texture is rougher than on the Sinistar

Q: Who currently owns a Duramold Sinistar?

A: There are three complete machines known to exist:

These duramold cabinets were designed to be multi-game machines, where you could just change out the boards, and play a different game.  I think they were quite a bit more expensive then the wooden uprights. 

Here are some pictures of the Duramold Blaster game.
