That was plan A, however, it will no longer boot at all. Fortunately, a kind list member offered me one of his Friends and Family apple discounts. I'm also planning on replacing the 4G of apple memory with 16G of OWC memory. So, by the time the dust settles, I'll have a quad core 2.3GHz I7 mac mini, with 16GB of ram, a 1TB fusion drive, a 27" thunderbolt monitor, apple care for the cpu, keyboard and magic track pad for about $2100. In contrast, circa 1985, I bought a 10 MHz 286 AT clone, with a 20MB (IIRC) hard drive, and 1 MB of 0 waitstate memory, and black and white monitor for about $1700. It's funny how a mid range home/office computer has stayed at around $2,000. It looks like the display was 720x350 pixels, so I've got 12 times the resolution, before adding a second monitor. 1000 times the cpu clocks per second, not counting instruction efficiency, and supplemental processors, 16,000 times the memory, about 50,000 times the disk space, at I don't know how many times the through put. And that's not even comparing with the Osborne 1, that my father bought for about the same amount of money a few years previously. It looks like 1980-1984 gas was about $1.20/gallon, http://www.randomuseless.info/gasprice/gasprice.html So the Osborne 1 and the AT clone were about 1400 gallons of gas. The mac mini system is about 525 gallons of gas or a bit more than a third as much in terms of gas. I think it was Peter Egan that would measure the cost of cars, and parts in units of a Pizza and a pitcher of beer. I'm afraid I don't remember prices of those well enough from back then to compare. Meanwhile, when I get the chance, probably a few weeks from now, I'll pull the iMac apart, and swap in a different drive to test it. Fortunately, I didn't have much of import on the internal drive, the only thing really important was my lightroom catalog, that just last week I had copied over to my rejuvenated laptop. The raw files are elsewhere, so I only lost the edits on a couple of not terribly important sets of photos, and that's only if I don't recover the drive, so I pretty much dodged a bullet on that one. -- Larry Colen l...@red4est.com http://red4est.com/lrc -- PDML Pentax-Discuss Mail List PDML@pdml.net http://pdml.net/mailman/listinfo/pdml_pdml.net to UNSUBSCRIBE from the PDML, please visit the link directly above and follow the directions.
