Are all Macintosh models without a name badge prototypes?

one of them is mine

Would love to see some good, detailed photos of it, as there don’t appear to be any out there. The Mac Plus brightness knob is really interesting. Didn’t know about that. I also didn’t realize it’s beige and not platinum! That is totally awesome.  

Always loved those smooth SE prototypes!

Good news for you: I did a thread on them a long time ago!!





I get a feeling the board may have been replaced at some point, but still...check out the case/details here!!

Great! Thanks for that link. Wow, that is an old thread.

It looks like the case is textured. Many prototypes don't have a textured case, although there are varying cases within prototypes based on which stage they are in.

Most everyone knows about the clear-case SE prototype. There exists an earlier prototype of the SE, which is beige, has no texture to its case, has no port icons (another telltale sign), has a Mac Plus brightness knob, and has a serial number indicating November 1986 as its date. (The serial sticker appears to be hand-made on a printer). I know of at least two of these still in existence (one of them is mine and is believed to have been sent to Carnegie Mellon University in Pittsburgh for testing at one point). To my knowledge, these were earlier than the clear case SE.

There is an LC Prototype that has been on-and-off eBay for the better part of the past year. It has a June 19, 1990 date on the chips. The case has texture and port icons. Also, note the serial number and date sticker on the power supply.

I can only hope they pulled the Maxell from it!!

I also have a IIcx prototype and it has a smooth case, so I am familiar with that one.

As I already said, there are many different 'levels' of Apple prototype machine.  This one is obviously a near-release or a release prototype, due to the fact that the ROMs are the final ROMs.

I was actually referring to ScottBarret’s Mac SE prototype, sorry!

But still, thanks for those pics too!

I’ve just located and purchased another one of these prototypes. I’m waiting for it to be delivered. 
 

Like this one it has no labels or serial number on the case. I can’t see the motherboard serial number but will compare to my other one when received. It has the same Apple Confidential ROMs, and this one has a marking on the bottom of the case that looks like “PVT” and possibly a codename. I can’t fully tell from the photos. PVT makes sense.
