Featured Vintage Repair / Recondition Project
Featured Recondition / Repair Project :
Electronic Quarterback (1978) (Coleco)
NAME : Electronic Quarterback
MANUFACTURER / RELEASE : Coleco 1978
DISPLAY / POWER : LED, 9 Volt
MODEL # : 2020
We thought it might be fun to share a vintage recondition project with other enthusiasts who might enjoy following along as we repair and work on this hugely popular vintage handheld electronic game from 1978.
This game needs a lot of repair work but most of the issues are very common. The 9V snap battery connector is worn / damaged, there's no sound, power switch is shorty and the keypad has poor bounce back and can become unresponsive. .. Read more... |

Featured Vintage Software
Featured Vintage Software :
Robot Tank (1983) (Activision)
ROBOT TANK,
VIDEO GAME CARTRIDGE (AZ-028)
Programming Language : 6507 ASSEMBLER
Released On (Media): Cartridge (4KB)
Released by Activision, INC. in 1983 for the Atari Video Computer System (VCS) and Sears Tele-Games Video Arcade.
Robot Tank at it's core is reminiscent of Battlezone, the fun vector graphics based arcade classic released by Atari in 1980. However I think Activision really jazzed up that arcade classic with full colour graphics and some great other features like changing weather conditions in addition to day light and night time. ..

Downloadable Resistor Colour Codes Chart
A nice downloadable and printable chart of the resistor colour codes for both 4-Band and 5-Band coded resistors. Includes new resistor value tolerances.
I created this chart in OpenOffice, mainly as an exercise for learning some of the features of the word processor but was happy with the result and decided to post it online. The file is in Open Document Text (.odt) format.
I think I had some trouble with the colour palettes so feel free to modify.
