I saw Pauls post about old DECtapes which reminded me about a bunch of
DECtapes I had lying here.
On my workbench I have a PDP-11/10 with TC11 and TU56 setup which works
nicely so I decided to image a few more DECtapes. For those interested in
old diagnostics and other things it can be worth looking into.
I have not tried to boot any tape natively since my M9312 need a TC boot
PROM, need to burn one.
I have tried to boot most of them in SimH, but many of them fail with a
HALT somewhere. Need to test this further on real hardware as soon as I
have a TC bootstrap.
D1.DSK had an I/O Error so it is not the full dump.
D2.DSK however boots to a prompt:
DDP1-V001 28K RSTRT: 155766
DIR .BIN 003 17-NOV-71
DTCOPY .BIN 006 17-NOV-71
D0AA .BIN 014 17-NOV-71
What is DDP1-V001? Some early diagnostics monitor? The filesystem seems to
be DOS-11 as RT-11 FILEX is able to read the directory with /S
D5.DSK is also a DOS-11 file structure and apart from quite some
diagnostics also contain FOCAL1.BIN
DT5.DSK contain a binary MOON.BIN which according to the label is some
variant of Moonlander / Lunarlander.
So, yes. I do have a system up and running that can Image that RSX11-D VT30
tape if needed. However it will be moved on the 27th of January.
