I should of course said operational 1900s. Nice to know the hardware
is around anyway. I never came across a 1500, though there is a
description of one in the programming notices folder I got with my
1301. I understand they were ICL badged RCA machines and that RCA and
ICL used the same 'standard' interface so presumably 1302, 1500
series, 1900 series and modified 1301s could all use the same
peripherals, if they had suitable driving software of course.
Back to the original post, does anyone know if there is a difference
between the "operators Exec for a 1900" and the executive used by
engineers and recorded on 7 track mag tape? Would this be of any use?
