[Simh] PIP10 on PDP-8 SIM

[Bob Supnik]

I was trying to get a debug setup for PIP10, per Ian King's mail, when I 
discovered that none of my OS/8 images have PIP10 on them. This 
certainly explains why the feature has never been tested before. I 
suspect that ReadAll and WriteAll either are not working at all, or are 
not working when the DECtape format is 18b. Another possibility is that 
PDP-10 DECtape format is not the same as 18b format, at the nitty-gritty 
level (format of headers and trailers).

If anyone has a canned OS/8 V3C image with PIP10, please post it 
somewhere (like Mediafire) and let me know by email.

Thanks,
