A friend of mine in Israel has a PDP 11/83 with 4M main memory, 300M Maxtor Disk, and 48 ports. For various reasons having to do with economic situation over there, they find it more worthwhile to continue to use this machine, maintenance and all, rather than to buy a new one. Some time ago, I posted to this group to ask about source versions of UNIX for this machine. The response of this inquiry made it clear that to get a source version, the friend would have to buy a System V license from AT&T at 53K. This is out of the question. Thus it appears that the friend will have to go the object version of UNIX route. In the responses, I was quite surprised to find out that there is a PDP11 version of ULTRIX available from DEC. Apparently also Mt. Xinu can sublicense binary versions of bsd 2.9. Are there other object versions of UNIX available? For each of these, X={ULTRIX, 2.9bsd, or other}, the questions are: 1. From whom is X=other available? where are they located? 2. If you have had experience with the PDP11 X, what is your impression of it as a UNIX? Is it stable? Does it perform well? 3. There is a limit of 128KB for each of I and D space. Is this limit easy to live with? Are there tools in X for overlaying programs to get them to fit? 4. Is X available in bootable form on tape? on an RM03 disk? 5. What is the cost of licensing X? Thanks, Dan Prof. Daniel M.
