(Sorry for the time-shifted response... I was away at vacation)
I've just come across a PDT-11 (model: PDT-11150
CJ)
It has 2 8" floppy drives, (which someone has labelled sy0: & dk0:)
on the back there are 6 db25's labeled console,printer,modem, term 1,
term 2 , term 3
What is this machine?? Can I make it run as a PDP11..
It's nice 'n' small & looks like it would be quieter than
my 11/44.
This is basically a pdp-11, based on the 11/2 chipset. Unlike most
other -11s, though, it is configured such that there is 60kb available
to the user (30k-words) and the IO page is only 4kb instead of 8kb
The roms know about RT-11 queue elements and the RT device driver
(PD.SYS) calls entry points in the rom to do the actual data
transfers.
You could use it in place of your 11/44, if you want to waaaiiiiit
for stuff to get done... not to mention the fact that there really
isn't much space on two RX01 floppies...
