I reviewed HSC50/70 tech docs. Yeah. They are PDP-11 machines. HSC50 uses TU58 and is F11 processor. HSC70 uses floppy drive and is J11 processor.
They uses SDI and STI devices through two Qbus registers with MSCP/TMSCP packets. I am interested to get copies of floppy and tape images for loading software. I have not find HSC90 tech docs yet.
