From mboxrd@z Thu Jan 1 00:00:00 1970 From: clemc at ccc.com (Clem Cole) Date: Wed, 3 Jul 2019 15:58:38 -0400 Subject: [COFF] DEC PDP-x Disks pre 1970 In-Reply-To: References: Message-ID: I'd start by downloading simh and see what storage any of the early DEC system support in the simulations. That will not be 100%, as systems like the PDP-9 did not originally support a disk, so the one Ken Thompson used had been a PDP-7 disk spliced by DEC CSS on the 9. So the UNIX V0 work we had to move the code from one simulator to the other (which was easy in SW - for the work we are doing at LCM on real HW, we are just emulating with a modern disk). Also, FWIW: might try the Classic Computers, Rescue mailing lists and maybe the simh list too (although read the source first ;-).
