G3 upgrade for PowerBook 1400
Well I stopped by Goodwill today and picked up a nice rolling office chair for 8 bucks. But I spotted one vintage apple product... A lonely cable all by itself. Not sure what it was used for, clearly not adb but probably for printer or modem. All I know is the connectors have a wonderful Apple logo on the end. Very long cable by the way. Might find some use for it. 
As for the chair, it will be a lot better to sit in while I'm soldering instead of a hard kitchen chair.

Assuming that you have a 48MB RAM card already (otherwise the VIEWpowr will not fit in), you are right to go. Stay with OS 8.6 and you will have one responsive, snappy and satisfying PB. Enjoy!

From the sound of it, I think its a AppleTalk cable. It's one of the few cables Apple has that is long.
Thin? 3 pins? Yeah Appletalk. If it has 4 pins and looks like S-Video, that's be ADB. If it has 8 pins, it's probably serial. Thick cable could be monitor, power, or other uses like special cable used for DOS compatibility card or Apple IIe card for LCs.
Always nice to see the cable rescued. Otherwise it may have gotten thrown out as unknown or "weird propriety" cable.

Yeah, I had a 1400cs with 64 MB RAM and a 242 MHz (IIRC, it was some oddball number,) G3 upgrade card. I loaned it out to an other-wise computer-less acquaintance who has since moved out of the country, last I heard. (He was still using it with Mac OS 9.1 and IE 5 as his primary internet computer over dial-up as of 2005.)
Great little machine. My dad had won a $3000 'shopping spree' at MacMall/PCMall back in 1996, and he was able to get the minimum PowerBook 1400, plus extra RAM. Passive matrix screen, slowest processor, not even the CD-ROM drive. After it had been replaced with a PowerBook G3, I bought it from him for $200 or something like that. (He had gotten the G3 upgrade and later full memory upgrade for it.)

No, it really was an oddball number. No even multiple of 50 or 66-2/3 I'm betting it was the 216 MHz G3 upgrade. (I know it was a Newer Tech one, so that article's mention of 216 seems right.)
Some quick math makes it appear that since the PB1400 uses a 33-1/3 MHz bus, this upgrade likely used a 6.5x multiplier, making a 216-2/3 MHz chip. I guess we're mostly used to 200+ MHz chips using a 50 or 66-2/3 MHz (or faster) bus, so 216-2/3 isn't a number that "feels" right.
