Among several recent acquisitions — another LW4/600 for spares, a 7100/80, a 21" Radius B&W Monitor, an SE, and a slot-loading G3 iMac/400 — a rather odd LC575 with a MicroMac conversion has arrived through my garage door. The LC575 is in excellent condition cosmetically, but had been "upgraded" via installation of a 5200/75MHz logic board. This required that a special metal extension to the case be screwed onto the back, over the rear ports cover, as the 5200 board was adapted to fit the LC575 by the addition of an extension board at the front.
Having suffered through use of a 5200 a decade ago, another of the series is about the last thing I want in my house, so the logic board portion of this kit will likely go — any interested parties can send me a PM forthwith — but it is truly among the stranger things I have encountered in 25 years of Macdom. There is a photo of the rear-end setup at http://www.ipod-repair.com/products/lb_p5200_upgrade.html , though alas the site does not show details of the special board which is attached. The latter adds maybe 2" right along the front, and has been soldered on after removal of the 5200 logic board's "socket" connectors (don't know what you'd properly call them).
What agonies people went through to be ppc rather than 68k users! I'll bet this conversion cost a bomb. You got to upgrade to ppc native software for your troubles, but almost certainly got a slower machine for all but the FPU scores charted in Speedometer.
The best thing about the setup, however, was that it came with a set of 64MB 72-pin simms. For me, that was a first, and these will be carefully guarded and sited in a suitable machine. I would love it if my Quadra 800 would accept them, but I hear that it will not; oddly enough, one machine said to accept 64MB simms is — an LC575.
Despite what I have seen others say about the ugliness of the LC5xx series, I am sort of attached to the form factor of the machine, and as the CRT in these is high quality, I may make use of the thing as a writing machine somewhere in the household. Once my LC550 board arrives in snowy Canada, purchased from the land of hurricanes ... where, Oh where can it be? ... my current CC Mystic's logic board will be going into this new-to-me LC575 to restore this new machine to 68k goodness, and my CC will become, apart from its badge, a CCII once the 550 board is popped in. All I need is a replacement rear panel for the 575, and it'll be good as new.
