A landmark piece of computing historical past popped up in a web-based public sale earlier this week. On the market as Lot #5006 (opens in new tab) on RR Auctions is a prototype Apple Laptop A, claimed to have been assembled by nonother than Steve Wozniak and owned by Steve Jobs. If that isn’t a tremendous sufficient pedigree to excite bidders, there may be photographic proof that that is the manufacturing prototype for the Apple 1 and was instrumental in securing Apple’s first ‘large’ order; promoting 50 pre-assembled Apple 1s to The Byte Store in Mountain View, California. Bidding for the PCB pictured above and under is at $278,005 on the time of writing and is anticipated to exceed $500,000 by the public sale’s finish (August 19).
The PCB wasn’t taken care of fastidiously by proprietor Steve Jobs. After securing the landmark order, it’s thought to have been forged apart on the Apple Storage for a number of years earlier than Jobs gifted it to the present proprietor roughly 30 years in the past.
Proof of its mistreatment are the breaks and cracks within the PCB and that a number of chips and capacitors are now not in place, presumably donated to manufacturing computer systems or subsequent initiatives within the storage. As well as, pictures of the working instance present that a number of giant orange Sprague Atom capacitors are lacking from the highest proper of the structure. The CPU is lacking too.
As that is the prototype of the Apple 1, we all know it ought to have featured an MOS 6502 CPU @ 1 MHz, 40 x 24 character show output, 4 KB of RAM, expandable to eight KB or 48 KB utilizing enlargement playing cards, and 456 KB of storage (tape). Nonetheless, as a prototype, this Apple Laptop A was a bit extra versatile, because the public sale information says it might have run utilizing a socketed Motorola 6800 processor as a substitute of the MOS 6502.
A number of different variations exist between this prototype and the primary 50 shipped Apple 1 computer systems. RR Auctions says that this mannequin is the one one soldered by Woz utilizing his attribute ‘three-handed’ approach. The public sale itemizing implies that the primary batch of Apple 1 machines was a product of $40 or fewer elements, however with the worth added by the meeting, software program, and so forth, plus revenue, The Byte Store bought them for $666.66 a machine.
Wouldn’t it be unsuitable to restore it and get it again into working order? Its situation is woeful, and it isn’t a really good-looking PCB. Nonetheless, we predict the machine’s future is behind glass and saved in its present state of disrepair by a collector or company.
