vtserver for geezer '11s

Hi, I modified vtserver to work on pdp11/34 and similar - the older machines that have the 000000 000000 000000 000000 @ odt prompt. I'm afraid I didn't do a very thorough job (hack night and just wanted to get it working) and in retrospect I wish I would've made a conditional argument to put it in this mode. Perhaps we should collaborate on adding this properly and adding other desirable features like compression for incoming "all zero" blocks when pulling images in from real hardware, etc. It's here if you'd like to use it: https://github.com/jritorto/vtserver You can run it with ./a.out -odt to facilitate its talking to the pdp at power-on and loading its initial boot sequence via odt in octal. You have to run the primary bootstrap with L 140000 and S <return> because I botched the parsing a bit in my rush to get things going. thx jake
