| LC III vs LC III+ vs Performa 467 | |
| Posted by: David Cook on 2025-03-21 22:41:08 I recently purchased a Performa 467, primarily for the novelty of such an obscure model number. Other than bundled applications, it is identical to the LC III+. Both machines are just LC III computers with a boost from 25 MHz to 33 MHz. Some weird things were going on at Apple in 1993. Here are all three machines:  The Macintosh LC III has it's name printed on the case and an auto-inject floppy drive. The Macintosh LC III+ has a sticker and a manual inject floppy, hence the rounded inset for your fingers to push the disk in. The Performa 467 is similar to the LC III+. Notice that the Macintosh LC III+ does not actually say "+" on the case. In fact, I have three labeled "LC III" computers with a sticker and manual inject floppy, but only two are 33 MHz. So, beware that it may just be an LC III with a manual inject floppy. I think the factory switched the cases over before they ran out of old 25 MHz motherboards. Here is the 68030 CPU with a 33 MHz rating.  Other than the drive, performance is significantly boosted by the speed bump. The columns are: overall, CPU, video, disk, and FPU, relative to the 25 MHz LC III.  I have installed 68882 FPUs into the empty sockets on these computers. By default, they do not include an FPU. All of the LC III, LC III+, and Performa 460 series computers that I have use the same version of the motherboard, 820-0650-B. They all suffer from capacitor C21 being installed in reverse polarity, along with the incorrect silkscreen. I've seen TDK, Aztec, and Dyna Corp power supplies in these computers. Because Dyna Corp (614-0028) is a little more unusual, here is the recapping layout:  My Performa 467 was manufactured in Singapore during the 40th week of 1993, which is early October. That's consistent with the Wikipedia article timeline.  It came without any additional memory or VRAM, but had the original Apple-Conner 160 MB hard drive, which still works.  Although I imagine the original owner likely added and removed some of the Performa software bundle, here is a snapshot of what the drive contained when I got it. The "Information" folder with the Apple phone number and other help was novel to me.  - David | |
Posted by: cheesestraws on 2025-03-22 01:33:42I think the factory switched the cases over before they ran out of old 25 MHz motherboards. Yes, and it's not just the LC III+. The same is true even of the LC 475; in some places, they were shipping 475s in the old case with a sticker saying 'LC 475' where the model number would have been - I don't have a link handy but there are several threads on the forums about people getting one like that and going 'um, what have I got?' The answer is 'you've got evidence that injection moulded cases are expensive and they didn't want to throw them away'. | |
Posted by: David Cook on 2025-03-22 06:00:55you've got evidence that injection moulded cases are expensive and they didn't want to throw them away Ha! hey were shipping 475s in the old case with a sticker saying 'LC 475' Did it look like this? Because I thought this was pretty bad when I acquired it.  Manufacturing: "Boss, we have a problem. Corporate keeps coming up with random model names." Boss: "No problem. Just make a generic case and stick an Avery label wherever you can find a flat spot." | |
| Posted by: Powerbase on 2025-03-22 06:08:11 Well, it took a while till Jobs took care of all that model chaos and cleaned up the lineup. Just think of the 33MHz LCIIIs as 'silent upgrades'. | |
| Posted by: dougg3 on 2025-03-22 06:14:21 Out of curiosity, is the system version on the hard drive 7.1P3? It sounds like that's the original version that shipped on the 467, and due to the absence of System Enabler 316, I would theorize that it's probably something earlier than 7.1P5. All of the stuff in the Applications folder appears to be standard Performa bundle stuff. In 7.1P5, the HomeWorks Sampler folder is in Documents (but maybe the original owner moved it). The one thing I'm not 100% confident on is AOL -- in 7.1P5, the bundled AOL folder was named "Apple/AOL Performa 2.0.1a". | |
Posted by: cheesestraws on 2025-03-22 06:27:12Did it look like this? Because I thought this was pretty bad when I acquired it. Some, yes, and some had a slightly better job where "Macintosh LC 475" was printed on a sticker and stuck where the model would be normally.

| Posted by: killvore on 2025-03-22 06:42:03 I think I've only ever seen the "sticker" version - consistent with how the "big pizza" Q610 cases were done  | |

Posted by: David Cook on 2025-03-22 11:29:25Mine is prettier Wow. That is unexpected. An LC 475 printed directly on the case like the original LC III. | |
| Posted by: adespoton on 2025-03-25 11:49:50 @David Cook , is that 467 OS still running 7.1P? | |
Posted by: David Cook on 2025-03-25 13:02:05@David Cook , is that 467 OS still running 7.1P? Yes, System 7.1P3 | |
Posted by: dougg3 on 2025-03-25 16:38:18Yes, System 7.1P3 If I'm not mistaken, I believe 7.1P3 is a system version that is currently unpreserved. The restore disk that Apple Authorized Service Providers could have had for restoring these models to the original 7.1P3 version (Market Software Series Volume 1) hasn't been found yet. You might have some lost software on that drive! | |
Posted by: volvo242gt on 2025-03-25 20:14:30Ha!The 475 I had was this way. I wound up installing a M0350's case lid on it, so it said "Macintosh LC", then "Performa 475" underneath. That meant that it had the indentation that went all the way to the edges, plus the plastic plug that filled the second floppy drive slot. Thought it looked better that way. | |
