The book is very pretty, and has some *outstanding* photographs of classic machines. If only the selection of machines and printing (at least on my copy) matched the quality of the photos, this would be on my "must by" list.
Newer photo-books like this rely on some special printing techniques to make their images stand out, such as printing a glossy image, with the non-printed portion paper treated to make it flat and bright white. It makes for a stunning presentation when it is done properly.
My book has several pages where the glossy images are scratched, and others where the pages are covered with scratches and dirt. I don't know if my pages sat on the top of a pallet or the presses were just dirty, but it clearly happened before binding, as in some cases, page 64 on the left hand side is very dirty, page 65 on the right is totally clean. The beautiful dust jacket is also badly scuffed up--a book like this should have been shrink wrapped--and the cover dinged. This Chinese-printed book would have been considered a "hurt" at my local press.
On this sort of book, that totally shatters the beauty of it all, and I think I will end up returning it. I considered asking for a replacement, but I am further disappointed by the selection of machines.
There are major companies of the era not even represented here. Not a single Data General machine...I would have expected the "70's photogenic" Nova, or a later machine like a S/150. No Burroughs, no DEC-20...the entire history of DEC reduced to two photos and one closeup of a pdp8 and a glimpse of the boot console panel from a DEC-10.
VAX? What's a VAX? No mention of a VAX here, but the TRS-80 I and 100 get four pages. I *loved* my Model 100, but this is not the place for it.
With a title like "core memory" and a pdp8 on the cover, I expected more early machines, yet the book dedicates six pages to the Apple I/II and four to the Commodore 64.
There is more coverage of the Commodore 64 PC than the entire history of Digital Equipment Corporation. Control Data is limited to a photo of the CDC6600 console, a photo of backplane wiring and two images of a boot switch panel.
Home PC's should really be their own book. But if they wanted to cover home PCs up to 1983, they should have hit "visually iconic" machines like the IMSAI or the Ohio Scientific PCs. How about some classic rare peripherals; the Atari 815 dual disk drive is a 9x9x12" box with nine LEDs in three colors, surely some unique peripherals like this deserve inclusion more than a two-page closeup of the Commodore 64's keyboard.
Now, I would like to mention the wonderful photos of SAGE and Johnniac. Had it not been that the photo of the SAGE light gun was covered with scratches, I would have kept it for SAGE alone. But as I said, in a photo book, damaged photos ruin the whole point.
I spotted a few factual errors and typos in my quick scan of the book, but the major errors are really errors of omission.
Conclusion: If yours is printed correctly and clean, it is a beautiful book and a bargain at the Amazon sale price. But if you are expecting a book primarily about machines running core memory, or minicomputers/mainframes from the 1970s as would be inferred from the cover and the name, you will be disappointed. I am.
