Close but it went S/32, S/34, S/38 -> AS/400 and S/36 -> AS/400
The System/36 was a completely different line and incompatable with the
S/38. It was also developed after the S/38 (1983 compared to 1978 I
believe). The AS/400 is based on S/38 hardware but has the capability
to run S/36 software. (Actually the new AS/400's can be configed to run
as a S/36 actually running the S/36 operating system.)
