  Hello. I'm new in the list. I write from 
 Spain; my name is Sergio. I have one question 
 to somebody that can answer it: Can it be 
 possible to obtain some sort of info about 
 "Compatible Time-Sharing System (CTSS)" from 
 the M.I.T ? I'm interested to do one IBM 7094 
 emulator and I should like to made on it the 
 modification that was made in the machine 
 that rans the CTSS. I think that there was 
 some manuals from MIT press ans internals. 
 I suppose that can be possible to obtain 
 it paying. I should like to hear something 
 about this. 
A guy named Roger Roach who is or was at MIT 
supposedly has magtapes containing the CTSS
documentation. If he does still have them,
I doubt he would release them from his possession,
and I don't think he personally has the time 
to try to recover the contents.

He might permit a researcher access to the
tapes at a facility local to MIT or wherever
he now happens to be.

I do not know Roger; I got this information
...
 from a third party. 
...
  Same thing is applicable to Multics question. 
 Somebody is doing a Honeywell 635/645 emulator 
 like I could confirm one week ago; in this way, 
 a primitive version of Multics may be sufficient, 
 I think. 
Most of Multics is written in PL/I; unfortunately, 
PL/I compilers are hard to come by.

...
  In both cases we think in Java like the platform 
 to do the work. In my particular case I want to 
 do some other emulators (Univac I, IBM 701, 
 IBM 1401 and IBM 650) because I have some info 
 about them (opcodes, etc). There is only a 
 question about the Univac I that nobody resolvs: 
 Can it be possible to obtain a detailed diagram 
 from the Main Console of the Univac I ? 
I, too, have had Java recommended to me as a language
for implementing emulators. I have concerns about its
performance.
