It was on http://simh.trailing-edge.com/, I can't seem to get to the site right now. The image was recently switched because macro wasn't working correctly on the previous one (sorted out by Hans, thanks). It now should be a copy of my tape s2.tu56 PDP-15 Master Tape S2 Page Mode (V5A Jan 24 1981) The site also had instruction on how to boot it. The rest of the pdp-9/15 tapes I have read are in ftp://ftp.pdp8.net/pdp9-15/ I don't have an actual 9/15 to run them on. Anybody have a spare? Not all seemed to work with the emulator. Nice to hear the machine is running again. David Gesswein http://www.pdp8.net/ -- Run an old computer with blinkenlights.
