Josh, THANK YOU (!) for the conversion of TSS from RF08 to RK05! I have a PDP-8/E with and RK05 and it will be fun to get TSS/8 running again.
I had TSS/8 running years ago - on my PDP-12 and RF08 (w/2-disks!). Unfortunately, I donated both to the CHM in the mid-90's - and they've been sitting in their archives ever since :( Cheers, Lyle -- On Mon, 25 Nov 2019 22:03:47 -0800 Josh Dersch via cctalk <cctalk@classiccmp.org> wrote: > Hi all -- > > We've wanted to run TSS/8 on one of our PDP-8 systems at LCM+L for a long > time now, and while we contemplated either (a) restoring our RF08 or (b) > building an RF08 emulator, I decided it might be fun to investigate a third > option: (c) modify TSS/8 to run off hardware we already have running, > namely an RK05 drive. > > And it /was/ fun!
