I have a Coleco-Vision (yes a video game) that lost it video output all due to a little capacitor marked '101J'. This cap is located in C70 on the board. I called Coleco and they have no one there that can answer my question expect if I pay $40 and send my unit in they will swap it for a working unit. All I need to know is what a 101J cap is. I guess I should go buy a Nintindo or whatever. I figured, to my suprise, that the Coleco had a Z80 justifing posting to comp.misc :-) +------------------------------------------------------------+ | Ed Lisle | ogcvax! | | Quantitative Technology Corporation | verdix! qtc!ed | | Beaverton, OR (503) 626-3081 | sequent! | +------------------------------------------------------------+

Ceramic capacitors are generally coded like RN55 resistors i. e. the last digit of the number indicates the number of zeros that follow the preceding digits to make the capacitance value in picofarads. Thus, "100" means ten followed by no zeros or ten picofarads. "225" means 22 followed by five zeros or 2.2 microfarads. The letter indicates tolerance. J=5%. A 100pF capacitor should cost about a dime. Seems a heckuva lot cheaper than getting a new computer... ...............................................................................
