EXIDY DISCRETE LOGIC HARDWARE
[ BACK TO MAIN PAGE ] - [ EXIDY HARDWARE PAGE ]
 
HARDWARE DESCRIPTION
When commercial video games were first considered the cost of CPUs were prohibitive, they were a comparitivly recent discovery and still extremely expensive. Nolan Bushnell, who would go on to form Atari, realised he could put video games together not using a CENTRAL processing unit but instead use decentralised processing in the form of relatively inexpensive TTL (Transistor-Transistor Logic) circuits spread over a whole PCB.
These early games could also include all sorts of weirdness using other electronic parts including in some cases parts of the monitor and audio circuitry undertaking certain jobs like controlling inputs.

Spiders From Space
1976 (Prototype)
Spiders From Space
Notes : Prototype
Notes: A Destruction Derby/Death Race variant prototype that had rockets and spiders instead of cars, unfortunately it didn't get past the play testing stage (as apparently "women wouldn't go near it").
 

Super Death Chase
1977 (Prototype)
Super Death Chase
Notes: Exidy changed the humanoid figures on the screen to look like skeletons (perhaps in an effort to avoid the controversy that had plagued its predecessor) and added a randomly appearing flashing bonus ghost for bonus points. There is a picture of the game in the Bill Kurtz book, Encyclopedia of Arcade Video Games, on page 41. Very different 36-inch-wide cabinet then the original Death Race cabinet. Rumor is they made a sample run of the game before they decided to not produce any more due to the negative publicity of the Death Race game. The game was shown at the 1977 AMOA show, but apparently never made it into full production and only a few units were built (less than 10 made).
Modifications were made by Arlen Grainger.
Essentially this was "Death Race II", a sequel, although the actual game did not change that much.
