RT-11 5.x install tapes?

[Jörg Hoppe via cctalk]

Hi all,

for work on TU58 emulator "tu58fs" I'd like to experiment with oversized 
tape images under RT-11 5.5, 5.6 and 5.7.
The images I know about are the classiccmp collections, Earl Evans 
pointed me to the RT11DV50.ISO archive.

However, in these images the TU58 driver files DD.MAC/DD.SYS/DDX.SYS are 
mostly missing.
Strange, because they claim to be pristine.

Somebody knows about original RT-11 V5 installation tape images?

Thanks,
Joerg
