Good effort, but 2 mins in Photoshop and Noiseware Pro make things even better,

I've been improving he color on these old photos. The slides have
faded, however using the tip from Pontus, I've been able to restore
them a bit.

Thanks for the response.
Shortly after I wrote the above message, I did join the simh mailing list
and ask my questions (about if the Mentec license was still valid).
Simon.
PS: BTW, is there anything you think the posters missed in the responses
or do you think the Mentec situation was accurately covered ?

It was a nice system. I used it to prepare some typesetting.

That GT-40 graphics processor was more like 2 full-sized boards. I think it
might have been more powerful than the PDP-11 that used it. But that's
probably true for most high-end graphics cards in PCs today to. (More
powerful than their host PC CPUs, that is. My cell phone is more powerful
than the PDP 11/05 in a GT-40, and probably has more memory too. We had 32

A paper tape reader. I didn't have one. There was no way to build
up permanent storage of anything I might create, except on the
remote PDP-10, using SAIL and MacLisp and CROSS for various aspects
of the archiving and cross-assembly.
Also, 4k words is more than 4k bytes.
Maybe I'll write a MOS-6502 emulator and see if I can develop a

Re: KL10s with PDP-11 front ends

You're correct, the DTE20 used plain ol' BC11 Unibus cables, and there
wasn't any special restriction on the length. The one from the first
DTE20 to the 11/40 front end was a BC11A-17, but cables from the other
DTE20s to PDP-11 systems in external boxes were often the BC11A-25 and
sometimes the BC11A-50. With the 50-foot cable, you do start running into
