Second the recommendation. As well as the other two in the series.
(Worth knowing that if you see "On The Edge: The Spectacular Rise and Fall of Commodore", that's the previous version which covers the same time period as all three new volumes in about 1/3 the page count. "A Company on the Edge" covers roughly the "8-bit era", though of course with Commodore there was a big overlap)
#1 is the "first edition". #2/#3/#4 covers exactly the same material, just expanding on it.
Hence my "warning", as there's not really any reason to read both #1 and #2/3/4 now that all are out. Especially as #1 is sold out most places and usually shows up on Amazon at extortionate prices for used copies.
Looking forward to The Early Years, but that's also more of an "extra" for those with a very particular interest in Commodore, as it's not covering their computer business but their pre-computer office furniture and calculator business.
