Re: Apple II Revision 1 Motherboard Wanted

Lol, didn't you post a while back something like "I have been collecting for 9 months and now I have found my second revision 0." Sorry that peeved me. LOL

Re: Apple II Revision 1 Motherboard Wanted

That's why I wanted a Rev 1, I've never had one!!!! Smile

Did you get that one that just sold on eBay?
Went for just under $500.

Re: Apple II Revision 1 Motherboard Wanted

I mainly was just curious if you won that auction, since you were specifically asking for a Rev 01.
Was not my auction but I did follow it.

Re: Apple II Revision 1 Motherboard Wanted

I looked at that rev. 1 board and am not sure what to think about the handwritten number in the upper left corner. Later revisions seem to be coded yyww (7928 equals year 1979 week 28)

This one has 4673 and week 73 of year 46 does not makes sense.

Were they just sequentially numbered in 1978?

Re: Apple II Revision 1 Motherboard Wanted

Well, before they used date code, they just numbered the boards. So, that number would be a revision 0 not a revision 1. Some of the early revision 1's still followed the numbering system. One member has one in the early 7,200 or close to that.

Re: Apple II Revision 1 Motherboard Wanted

The print underneath the 6502 suggests, that it is a rev 1.
The seller also wrote rev. 1

But it is definitely a low relatively low number. Went for ~550 $ - would that qualify for the laughable thread?

Re: Apple II Revision 1 Motherboard Wanted

One of his other boards was listed as a "clone" The board had some weird revision number also. I just mentioned the serial number to suggest maybe the revision 1 board is suspect also.

Which auction are you guys talking about? The only Rev 1 I've seen on ebay is the one that went for $450ish.

Re: Apple II Revision 1 Motherboard Wanted

Sorry,

I referred to this one:

http://www.ebay.com/itm/201523685980

Forgot to include the link in original post

I looked at his other listings again, he differentiated pretty openly between clone and original. The clone-board also went for a fraction of the price

My eyes are getting bad - are you sure it says 4673 and not 4678? Because 1978 week 46 would make sense for a rev.1.
Alternatively, since the seller is in Europe, could it be that the PAL version boards had their own numbering system, and therefore this is PAL rev.1 board serial number 4673?

Re: Apple II Revision 1 Motherboard Wanted

Well, that's why I mentioned the "Clone" board he was selling. Because the number on that board would make it a revision 0, and it is clearly not a revision 0.

Re: Apple II Revision 1 Motherboard Wanted

This discussion brought up another related question for me.

Did anybody see clone-boards from the 70s or 80s that also printed the original white color Apple Computer inc. writing and all?

I read that the Apple 1 clones are more or less 100% copies although I thought that they have small markings that show that they are copies.

So the question is:

If there is the "Apple Computer" marking in white on the board and the tin/copper markings underneath the green paint, is it still a clone? Would that then be a rare clone or are there thousands of 100% identical copies?

Re: Apple II Revision 1 Motherboard Wanted

Well to put this to bed.

Apple-1 clones are not 100% copies. Put one next to the real thing or simply hold one after the other and you can tell. Modern PCBs are very different than ones in the 70's no matter what anyone says about using old PCB mfr techniques. Plus they have markings and things that are not 100% right. But to a novice they seem the same.

As for Apple II replica motherboards. I wasn't aware of any replicas back in the day that copied the logo. What I can tell you is that the serial number on an apple II motherboard will come off with Alcohol, so never trust it. It's just sharpie not security marker. It also means be careful cleaning your boards.

Cheers,
Corey

Re: Apple II Revision 1 Motherboard Wanted

Sorry, if I insulted anybody. I know that they are not "exactly" 100% copies. I'm not a native speaker. I was trying to imply with the "more or less" that they are much closer to the original (including the Apple logo or company name). Even I as a novice could see the differences on my Apple 1 replicas vs. the original. Thanks for the info that you did not see any replicas that copied the logo back in the day. That reconfirmed my own memory, but I can only judge for Europe as I was not in the USA during the 80s.

So long

Re: Apple II Revision 1 Motherboard Wanted

I don't think you were insulting anyone. I just wanted to be clear. On eBay people try to sell "100%" accurate replicas and trust me they aren't. I want to manage people's expectations. Some are good replicas like the Mimeo and some aren't but are rare like the Obtronix.

As for why the Apple-1 replicas can use the logo... Woz made the apple-1 "open source" back in the day.

Re: Apple II Revision 1 Motherboard Wanted

The truth is that Apple chooses to not bother us reproduction builders or is totally unaware. The copyright of the board design is most likely owned by Apple, even if Woz did release schematics prior to the creation of Apple. I say most likely, because whether PCB designs can be protected by copyright or not is a bit murky in itself. However, I'd say the Apple Computer 1 logo most likely would be protected by some kind of trademark that Apple owns.

Re: Apple II Revision 1 Motherboard Wanted

Hi,
I guess there could be a part clone category.
For instance I have a Rev 1 that I put into a
Clone case since it had a nicer keyboard with
a numeric keypad and changed the power supply
along with the power connector back in the Summer
of 1980 after I left Apple. I consider it more of a transitional
MB since it still has the same color edge connectors
as my Rev 0's.
BTW, I do enjoy reading all of the conjecture regarding
serial numbers and date code.
I was hired by Apple in April 1979 and started in June
1979 and left at the end of Summer 1980.
MB's and base plate S/N's really have no relation.
We would receive cartons of MB's from Flextronics
(As well as all the other adapter cards) then start
testing. I started with testing and debugging the adapter
cards then moved onto the MB's. During test and debug
the main objective was to get as many good MB's
working as possible so there wasn't really any attention
that was paid to date codes and such. I worked on
a few other projects like the Silentype printer and A3 before
leaving as well. When I left the company was starting to
make little divisions and the Mac line was starting to ramp up
in Fremont. It was also interesting to see the Lisa in development.
BTW, if anyone would like me to upload pictures of my early Rev
MB's let me know and I will give it a try. Needless to say since the
even my Rev 0 MB's were in continuous use there are times that
I would swap out some of the TTL to improve reliability. That being
said since I have been building everything from home brews to S-100's
and newer systems since the 1970's I have a decent collection of 'period' TTL...LOL!!!
During that time there were a few A1's around but everyone I knew alwayswanted the latest and greatest...oh well.
Maybe someday I will build a Replica A1 since I already have some of the discrete parts as well.

Re: Apple II Revision 1 Motherboard Wanted

I have a question you might be able to answer Kelvin.. I have an original II with a Rev 02 board in it. The date code on the board is 7902. However, I have seen Rev 03 boards with 1978 dates. Can you explain how that would happen? From what I understood about A2 manufacturing it was possible for an older Rev board to sneak in among mostly later Rev machines.. but I thought the date codes would correspond to when the board was made.. and I assumed a Rev 02 would have been made earlier than a Rev 03 regardless of when it was actually installed?

Re: Apple II Revision 1 Motherboard Wanted

Flextronics could have been the ones who put the date
codes on the boards to keep track of when they were built.
I know for a fact that I never put one on during test and debug.
As I had mentioned the boards came in by the carton.
There was not a lot of attention given to the Revisions since
most of the boards I worked on were Rev 1 or newer.
I myself never let a Rev 0's go out the door. There could have
been some early Rev 2 PCBs that were sent to Flextronics and
they went ahead and built them even though Rev 3 PCB's were
already available at the time. It wasnt an exact science back then.
It was matter of test, debug and fix if necessary and ship.

Re: Apple II Revision 1 Motherboard Wanted

Thanks so much!

I've been collecting Apple IIs for a while now and every time I think I *know* something, it turns out I don't. The mixing and matching of board revisions and dates makes it almost impossible to determine originality. I had thought I had scored pretty good with my Rev 02, but I fear if I go to sell one day buyers will look at all the Rev 03 units with lower serials and conclude mine isn't original. Not that I plan on selling any time soon. Smile
