We didn''t sell many. I reverse engineered the os/9 level 2 card that was needed for os/9. It did the ram memory mapping as well as extra ram. I probably have my sketches somewhere. The S1 was a stunning piece of hardware in its day - it was full of custom ics as compared with the mb6890 which was pretty well all standard ics. author date text CraigM (Australia) Friday 15th November 2013 Just came accross this old thead. I too had a Hitachi peach and ended up with a S1 as well. They were sold in Australia. Was a great little beast of a box. I ended up purchasing OS9 from Hitachi Japan. The only issue is that out of the box it couldn''t read other 5.25" floppy disks from other OS9 systems. My brother who was a Flex/OS9 freak ended up re-writing some of the device drivers so I could read/write disks off his various systems. Was way ahead of it''s time imho. Ended up selling it for a pitance in the end :( craig author date text Roger D (California) Tuesday 23rd November 2010 My family had one of these, growing up in Australia in the 1980''s. In fact, it''s still there and as far as I know still works! author date text Leon Howell (Oregon, USA) Tuesday 1st February 2005 Could this be another OS-9 system, like the Fujitsu's? 341 url date https://web.archive.org/web/20221205112156/http://www.old-computers.com/museum/computer.asp?c=341 2022-12-05

Pat from Australia, remembers:
On a whim, I looked up the Hitachi S1. When I was much younger - probably in 1984 or 1985 - my dad worked as a Hitachi reseller in Australia. The S1 was not sold outside of Japan to my knowledge, but it did have English available as a language so that may not be for certain. What really caught my attention outside of the amazing computational capabilities and colours (having used Hitachi Peaches for quite a while) was that the S1 (or at least the one I was playing with) had a hard disk! If only I could remember the name of the games I was playing on this thing!
