Current owner kindly share a lot of information about the board:
It was deliberately kept in fairly clean room, sealed in plastic bags to prevent moisture access.
The owner is from Canada but the Apple-1 is in a bank vault in Florida.
The video connector was already removed it by previous owner because it didn’t fit properly in the case as a result of positioning of the board in the case. As the adhesive dried up over time and naturally came loose. Keyboard connector was replaced by Corey Cohen.
The pins protruding from the keyboard upper 2 pins are how the original owner worked around the keyboard he acquired for power difference between the Version D, versus the designed Version B that Corey was accustomed to and could not get to work using the B pinouts which he expect to work. I got it to work with the only change being the +5v connection being moved on the connector, no board mod required.
You will clearly see the “77” on the lower right corner I use to name the board A77
The Back of the board is as perfect as could be, nothing needed beside soldering the era valid video connecter by Corey! The darkened area in upper left is a natural process of use. The Apple-1s are notorious for running hot, due to the demand on the LM323K for +5v caused by the power requirement of the original (non CMOS or L designation for low power versions of TTL) chips.
Keyboard is indicating the version D rather than the more common version B, which Corey and Mike did not know existed. The difference is the connector pin for +5v is five versus the Ver. B on 4. Once I moved the cable, the board and all the Keys functioned perfectly, undoing Corey’s cable. The fact all worked sparked the thought of being a military version, and a prototype as the board is all hand soldered.

More information will be available later. Including more pictures and maybe a video.
Corey Cohen along with me looking on, has completely verified and tested my unit at the lab he uses in NJ for the purpose, meeting mid-day Aug 4th ending mid-day Aug. 5th 2015. To complete all testing and verification. I am Canadian and in the industry.
The transformer area on the case was in October 2019 reinforced, to prevent damage. Because the adhesive deteriorated. This happened to other Apple-1 as well.


Current owner kindly share the history of this Apple-1:
In 1978 a customer came to a computer store asking if they were part of the program Apple was offering to trade up from his Apple-1 in wooden case and was sent to me. On 1st sight I knew it would have a place history, verified it worked and sold him a repaired Apple II for couple hundred, which he was happy to get as Apple was no longer supporting it. Apple was not extending the trade up outside the USA.

The Apple-1 spent its life in my controlled environment basement along with all my other artifacts, being powered at least every once or twice a year. I heard the story on the radio while driving in Florida on my birthday in 2015, of the lady in California that was being sought to be paid. I called my sons immediately in Montreal (Canada) to go get it…with renewed care. I searched and found Corey Cohen as I would be an unknown entity, met up with him and we took a gig of videos and pictures, which I can provide as you may need. Corey could not fix my keyboard, which I ultimately did. There was nothing wrong, except he assumes it to be a Version B but really is a D. I conjectured with others who felt it may have been a military version under development.
It was on exhibition at Vintage Computer Festival West 2019 at the Computer History Museum in Mountain View. Achim Baqué verified it and made pictures.Owner is known to Apple-1 Registry curator Achim Baqué.
In October 2019 the Apple-1 was for sale at eBay.


no auction


White ceramic MOS 6502 CPU (0376), plastic Synertek SY6520 PIA (7630), 8 KB plastic Mostek MK 4096N-11 DRAM (7634), 4 blue and 4 yellow capacitors
CPU was probably changed. Ceramic 0376 match first batch of Apple-1 boards. The green slots look good and is not broken. Part number and date code 05 76 is correct.


Original Apple Cassette Interface, Datanetics keyboard BD 02-1661-01 Rev D from 1976 (Insp. stamp Sep 21 1976). Original Byte Shop wooden case with TRIAD transformers from 75 and 76!


Very good. TV connector was missing. It is replaced. Excellent looking back.


Printed number 77 in the lower right corner can be found on other Apple-1 second batch as well but only on a few.


About the current owner:
I started in microprocessor technology the early 70s and still enjoy what I do. I built, tested and “Played” with them including Altair, Imsai 8080, clone of the Altair S100 bus systems publish in Popular Electronics in late 74. It stuck with me. I was a student repairing Radio Control equipment affording me to be in my hobby and micros and I still fly. In Early 77, the electronics store I bought parts decided to start selling Apple 2s. No one knew anything about them and had to ship back to Apple in California for warranty repairs, which took a month. The 2s were covered under warranty, but they paid shipping at $45 each. I offered to repair them and pay me the $45. Within a year I became the main repair center for Apple in Montreal as other stores joined the Apple revolution while adding Turbodos networking and CPM systems.
