.I tell ya, I got a knack for finding CEDs and their players. I have no idea what it is about my area, but I'll be damned if I don't run across this stuff on a semi-regular basis during my swap meet and yard sale escapades. This morning I grabbed another RCA Selectavision SFT100, the first model introduced in 1981, and a few select horror titles for $12. The one pictured is my working SFT100 found in July 2009 for $25. Both very decent prices along with a few other cheap dud players that were salvaged of their removable needle cartridges for reserve purposes (good to keep this in mind, these styli can go for nutty prices on eBay)
CED, or Capacitance Electronic Disc, was an analog video format introduced in 1981 by RCA that utilized a needle stylus and dense vinyl platters for video/audio playback. Basically, the format was the absolute limit of analog medium innovation before the widespread prevalence and obvious advantages of the laser revolutionized both home video and audio forever. The CED format was meant to be cheaper in end consumer cost in comparison to the others, so maybe my ease at finding this stuff reflects my region being populated by bums. Well, at least that's one possibility...
Sadly, the player either has a worn out belt that drives the servo arm along the disc for playback, think a record player's tonearm except motorized, or the arm motor itself has gotten goofy. The belt seems to have extreme difficultly with initially gripping the motor's spinning road but when it finally does the arm mechanism speeds along as if the fast forward button is engaged during what should be standard "Play" mode. I tried to "punch" and jiggle at the FF button to disengage it if that's the issue but there's no change. The rotating platter seems to have no problem spinning up to speed and otherwise the player appears to function properly.
Below are pictures of the odd CED loading system with Halloween II bought with the player. The vertical bar running across the top back of the machine is the servo arm with the white plastic gears and bits on right side (incorrectly) controlling it. The slender black "pull button" with the writing sticker around it on the arm is the stylus holder. You pull that black tab to the right and a latch door opens giving you access to a cream-colored plastic box of the thing containing the needle you can pull out and replace (or plastic bag for safe keeping). Be sure to check to see if it's in there before buying one. Most players have top access door on the cabinet, like this SFT100, that have be popped open without tools to check it.
