Hi Clem, ... Three: the ISBN you gave doesn't match Amazon's. :-) That's how I tried finding it first and why I thought the URL might be useful. -- Cheers, Ralph.

Hi Clem, ... I error-correct that to ‘That was the US number from...’. :-) If so, I think you've either missed a subtlety in the emails, something's gone wrong in publishing, or you had a pre-print where they didn't know the final number for the back cover? Yours: 978-0-262-54299-0 Fails ISBN's check-digit Mine: 978-0-262-54290-6 Added dashes to match Diff: ^ ^ Amazon's ‘Look Inside’ shows a paperback ISBN-13 of 9780262542906 which matches what they put on their web page. OpenLibrary give the same, https://openlibrary.org/books/OL32702646M/A_New_History_of_Modern_Computing as does the Library of Congress catalogue entry. Anyway, it does look interesting. I see from the index that they even mention the Acorn Archimedes, the world's first consumer device with a RISC chip, the Acorn RISC Machine, AKA the ARM 2. I learnt ARM assembler on the A310 model before switching to the R140 which shipped with RISC iX, Acorn's Unix, and I still get asked to do the odd bit of swtch() assembler porting on embedded ARM Cortex. -- Cheers, Ralph.
