I first saw this in an old April, 1973 edition of _Radio_Electronics_ magazine in the New Products section. At the time, I was young and naive and thought it was a real chip #-) !! My photocopy of the data sheet is pretty bad, but it seems that the copyright date is 1972. I am cross-posting this to sci.electronics and directing followups to that group since I'm sure that others have fun things to add to this (see also, EDN, April 3, 1986, "Single-board nuclear reactor supplies power for 12 years". +------------------------------------+----------------------------------------+ | Gil Kloepfer, Jr. | Net-Address: | | ICUS Software Systems | {boulder,talcott}!icus!limbic!gil | | P.O.

The original copyright was 1973. What I consider to be some gems: Vff (for the filaments, of course), plus the neat graph of Iff vs. Vff _____________ Chip Destruct The drain (sight gag) First-in, Never-out (FINO) asynchronous buffers Chart of pins remaining vs. socket insertions An EDN letter to the editor in the late 70's gave an instruction set for a Tektronix WOM tester. Among them were: RIRG Read Inter-Record Gap SPSW Scramble Program Status Word MLR Move and Lose Record CRN Convert to Roman Numerals EIP Execute Programmer Immediate (a real gem for the assembly programmer types) LCC Load and Clear Core HCF Halt and Catch Fire (my favorite) EIOC Execute Invalid Op Code SRSD Seek Record and Scar Disc -- Rich Straka ihnp4!ihlpf!straka Avoid BrainDamage: MSDOS - just say no!

I am looking for a good CD player in the $200 price range. From what I've heard and read Magnavox makes one of the best in this $$$ catagory. I don't trust JVC or Sharp because friends have had problems with their respective CD players. Can anyone give me some advice on what CD player YOU like or what you've read? Thanks in advance.

The sound quality is pretty good, although not incredible, but hey, what do you expect? The cost was around what you're talking about, and I haven't had a moment's trouble with it. Of course I don't abuse it physically, I just use it alot... -- The Foundation for Unmitigated Sillyness uunet!actnyc!rmf Department of Redundancy Department City of Kansas City, Kansas
