As a recognised 'expert' (note the inverted commas! ;-) ) on LC series machines I feel I should stand up.
First and foremost the Quadra 605 and LC475 are the same *board* but different *cases*. The LC475 case has the LC style long foot log the front with two thin feet at the tail, and sits slightly nose-up, a design which originated from the need to have the 12" Color Display sit at the right angle when it was atop the LC.
The 605 sits flat and has 4 'Quadra Feets' as i candidly refer to them as, which are the same as those on many of the later Quadras, that bulge out of the case at the side slightly. Believe it or not the bulges were officially referred to as 'Mammalian Protuberances' by Apple (if you don't understand, look it up, try not top blush too much!!).
Secondly I will explain the definitions and styles from LCIII to LC475 from the top:
LCIII:
25MHz 68030
Absolute Ram Ceiling at 36MB
1 VRAM Slot (256k onboard)
Soldered SMT CPU with FPU socket.
Available in *either* the early LC/LCII style case with auto-inject floppy drive *or* the later LC475-style 'fish mouth' case with the manual inject drive.
LCIII+:
33MHz 68030
Absolute Ram Ceiling at 36MB
1 VRAM Slot (256k onboard)
Soldered SMT CPU with FPU socket.
AFAI can establish this was only made in the later 'fish mouth' manual-inject case, though I may have found an example in an original style case, can't be sure. Note there are NO distinguishing marks on the case that define it as a III+, only the CPU speed (33MHz as opposed to the III's 25MHz) can define which of the two LCIII models it is.
LC475:
25MHz 68LC040
132MB RAM ceiling (if you can find a single bank 128MB 72-pin SIMM you are a luckier person than I).
2 VRAM slots (non onboard)
Socketed 68LC040 CPU. FPU only installable by swapping CPU for MC68080.
This was the last 'pizza boz' LC, made in the later 'fish mouth' manual-inject case. *However*, again I have unconfirmed reports of them in early-type cases.
One important note is that *all* LCIII, III+, 475 and Q605 boards are *completely* interchangeable. I ran a 475 board in my III+ for about a year. My website, flatpackmacs, has a complete tutorial on how to do this.
<hears call bell> OK, remember learn this, <raises voice over sound of moving chairs and chatting kids>THERE IS A TEST ON MONDAY!
