Yet another Apple-1 scheduled to be auctioned

While the most recent Apple-1 auction failed to close with a successful sale – bidding on the non-functional unit didn’t meet the $80,071 minimum price – another unit is scheduled to hit the auction block in November.  This particular Apple-1 is not only complete and working, but  comes with several original peripherals including a 9″ Sanyo monitor, a Datanetics ASCII keyboard, and a transformer.  The original documentation is included with the lot, though the cassette interface and tapes are listed as “reproductions”.  It would also appear that the MOS 6502 chip currently in the unit is not the original ceramic CPU.  Read more about the auction here.

Open Apple podcast #20 (October 2012) now available

Ewen WannopThis month on Open Apple, Mike and Ken chat with Ewen Wannop, British programmer of 16-bit telecommunications programs such as Spectrum, SAM, SNAP, and SAFE. The hosts share feedback galore from the last episode and contemplate how to record a live show. After catching up on some headlines from last month, we plow forward, celebrating the return of an interactive fiction publication and grumbling that even beginner IF can be as obscure as the medium is infamous for. The September 2012 issue of Juiced.GS just shipped, and with it, a look at what features a hypothetical System 7.0 operating system would include. Is it reasonable to consider that a software upgrade warrants a hardware bump, and what the next model of Apple II would look like? Photos of Steve Jobs in his natural habitat show an Apple stronghold as Spartan as ever, but you can decorate yours with Melissa Barron’s screenprints from Etsy. There’s a Disk II floppy drive on eBay that holds within it a working Mac mini — a cool hack, but is it worth a cool grand? We question the value of purchasing free software on eBay and marvel at everything from lighters to thumb drives in the shape of an Apple II.

Find the show at the Open Apple Web site or in the iTunes and Zune podcast directories.

Latest batch of Mimeo-1s to go on sale

The latest batch of Mike Willegal’s Mimeo-1 Apple-1 replica kits is scheduled to go on sale shortly.  Willegal has upped the revision number to 1.01 to go with some changes he made to the latest version:

What follows is summary of changes.

1) I changed the solder mask to matte. I’ve had a few people bugging me for years to do matte, and have finally been convinced to change. I did a matte run a few years ago on the Apple II rev 0, but thought the glossy look gave a superior “look”, though not quite as authentic. I have been doing glossy since then. Even a board made with matte solder mask will not exactly match with an original board, as PCB manufacturing technology has changed and is not possible to replicate exactly with modern processes. I suppose someone could attempt to replicate old manufacturing process, but keep in mind that many of the raw materials going into a PCB have changed since the 70′s, not just the solder mask. In any case, once you populate the board with components, the difference isn’t very noticeable. If I had to pick which bare board I was going to frame, I’d pick a glossy board, since it just looks a bit flashier. Be aware that he matte boards also look awesome, and will be a step closer to the original in appearance.

2) A few minor changes were made to the silk screen, to better replicate an original board. Some of these minor differences from the original were found by me and some reported by other people. Most of the differences I’ve known about, are so minor, that no one other than me, ever noticed them.

3) A few minor changes were made to the copper layer on the front. Same comments as with the silk screen layer.

4) The board grid coordinate numbering and lettering along the edges has been slightly reduced in weight, to better match to original.

5) Mounting holes were shifted ever so slightly to better match up with original Apple 1 mounting holes.
