Re: [TUHS] PDP-11 questions

In the PDP-8/A mincomputer handbook (http://bitsavers.trailing-edge.com/pdf/dec/pdp8/handbooks/MinicomputerHandb…) the desktop models are called MS800A, MS800B, MS880A and MS880B. But I know there is some manual that calls them DECsystem as well, but that might not be any document that has been scanned. I have paper copies of a lot of stuff somewhere in my cellar. The COS-300/310 system reference manual is on Bitsavers (http://bitsavers.trailing-edge.com/pdf/dec/pdp8/cos-300/DEC-08-OCOSA-F_D_CO…) Reading through it, it's very clear that this is not OS/8, or any derivative of it. Check the file system details for example, the file name syntax (device is added after the filename, with a comma separator), various CUSPS like PIP, or the transfer program available to transfer files to/from OS/8. I tried searching around more on COS-310, but only came up with other peoples memories (https://en.wikipedia.org/wiki/Talk%3ADIBOL) but which also suggested that COS-310 came with the 8/e and later 8/a, including in a desktop config. As for the EDUsystem thing, that must have been my brain. I can't find any connections. The EDUsystems were in fact having numbers like 10, 20, 25, 30, 40 and 50. No 310 or anything close... But EDUsystems do not really predate the 8/A. They carried on in the PDP-11 systems as well, beyond the 8/A era.
