DG S/130 progress

Then I developed a tool to connect it to PC via serial, using the console port; this tool is somehow similar to VTserver for PDP11 realm, but more expandable. Basically, you can do memory transfers between Nova and PC (both directions), and execute almost *ANY* I/O instruction on the Nova, under the strict direction of the PC. On the PC, a tool developed in Python is used to bootstrap a special binary program (using Program Load feature on Nova), and then to execute special scripts, prepared for particular disk and/or tape peripherals, to dump a device to image file (compatible with SIMH), dump an image file to device, format a disk, and so on... As all these procedures are controlled remotely by the PC, on the Nova always sits the very same small binary code, thus supporting new peripherals should be very easy, once one understands how the whole stuff works. I already developed (and debugged using an emulated Nova3 on SIMH) all is needed to read/write/format disks on 6030. I think the very same code should work on the S/130, so if you want you could give a try.
