No, of course it does not, it is just a normal 1571 with the updated ROM inside. It also has the same type label as the normal 1571, there is no mention of a 1571-II on the drive itself. The 1571 probably didn't sell too well after 1987 if you consider the release dates of the 128DCR (with the new internal 1571CR drive which had several 1571 ROM bugs fixed) and the 1541-II (which featured the same integrated r/w amplifier as the 1571CR). They must have planned the 1571-II to be made at about the same time, but instead they continued to sell the old 1571 and in 1989 (!) finally released the update ROM for the 1571. It must have been at that time when the decided _not_ to build a 1571-II after all. Development costs would've been restricted to making a new board layout, since most of the 1571CR and 1541-II parts could've been used without any modifications. It would be quite much fun (if one has the means to make a good double sided PCB) to build a 1571-II replica from a 1541-II and some 1571CR spare parts :-) Only a 5710 would be needed in addition to what is already in the 1541-II, plus a double sided drive of course. Maybe the 5710 can be even hacked onto the old 1541-II PCB, this would save a lot of labour. This reminds me of the 1541C, which seems to be a semi-official name. The drive itself doesn't have a 1541C label anywhere, but it's box carried the name 1541C in _very_ large letters. Nicolas - This message was sent through the cbm-hackers mailing list.
