What about various lesser-known systems? Given that
most
people used these systems through remote terminals to begin with, a
public access system would seem to be an ideal way to experience them,
but how many of them are available in such a way?
Mine is too old, no serial connection, no operating system, not even
an operator terminal. Bootstrap from drum and read 80 column punched
cards. I have modified the bootstrap to read from paper tape and I
have now got a bit bashing serial link which uses 100% of the CPU to
make it work - no time to service any terminals though, no interrupts
and no multi-programming capabilities.
It would be nice to see a ICT/ICL 1900 online one day.
The first machine I used was an IBM 7094. We punched our cards, they
were taken to London and next week we got our listing back saying
syntax error on line 1.
