This is interesting. The one thing that is different from my observations is that Classics usually take less time than SEs to warm up. Perhaps eliminating the PDS slot and second HD/floppy helped to speed it up. > You > failed to mention that the other 6 Classics were > Classic II models. BIG > difference. Actually, only one was a Classic II, and I knew it would win anyway. The others were all Classic I's, ranging from May 1991 to July 1991 in manufacture date. > A stock Classic (NOT II) would probably > get beaten by the SE > FDHD.

Most of the books I've read with benchmark scores in them had the Classic on top, but I've usually seen the FDHDs beat them. However, the older SEs (non FDHD) seem slower on Speedometer. I once tested an FDHD, a regular SE, and a Classic, and the FDHD won, the Classic in second, and the SE regular in third. All had the same configuration, the Classic may have had only 2MB RAM though with the others at 4MB. For statistical purposes, I've been using Speedometer. Not sure of the version (may be 3.0 but again not positive) and have run it on dozens of Macs. > The Samsungs are also anti-reflective -- not sure > about blue-er.

It seems that Samsungs are usually on SEs but I've got one on a Classic II pulled from special ed. as well. >Not sure what > you mean about taking the "newer monitors".

The difference is in the connector, as I found out when taking an earlier Classic apart. My theory is that there were a lot of the older connector left over from SEs and Pluses that had just been discontinued. Since the SE/30 didn't make it through 1991 they figured they could use a bunch of them on early Classics. The other design may have cost less, and Apple may have figured that with a Classic II on the way to replace the SE/30 anyway that they would just wait until inventory ran out. The Classic in question had a December 1990 manufacture date. Thanks for all the info, though. After working with iMacs and Power Mac 5200s the past few years it's been fun to come back and talk about these old machines again! Apple doesn't make them like they used to...
