[ih] Some words of presentation and some needings

[sp]

Hello.

I've recently suscribe myself to this list. I had it in mind from some 
months ago, but diverse matters didn't leave me time to do it. I live in 
Spain. My name is Sergio. I work in IT and Data Processing from 24 years 
ago. Most of the time in IBM Mainframes enviroment. I had occassion to 
know in working state some devices from the 60's and 70's and early 
80's. We had some of them yet rounding by the CPD, but they shall go to 
the dumpster in some weeks. One 3705 controller, for example.

But the fact in my career was the IBM PC and its compatible machines. 
 From 1986 to our days, the evolution was really amazing. Many things 
changed during these years in the conception of the Computing practices. 
But no one so amazing than the massive use of the Internet. I'm in the 
net from 1994, and I remember my first five years on it like the most 
impressive in all my life.

I ever was interested in Classic Computing and the History of Computing 
too. I suppose it began with our old (and actually trashed) IBM S/370 
3031 running DOS/VS release 34 and VM R6. But the real thing is that my 
encounter with the Internet made me search for more information about 
it. And then discovered ARPANET.

I could obtain some documents about ARPANET during last years in diverse 
websites, but I don't have some other of particular interest for me (in 
particular, the Protocols Handbook, and some other speaking clearly 
about the commands needed to use the IMP and TIP, and defining in deep 
the software architecture of the IMP System software and its management; 
the obtention of any one of these would be agreed in deep). I must say 
too that I'm using the documentation to develop one IMP/TIP simulators 
network during my free time for fun :-) But is not an easy task. This is 
giving me a real idea of the work involved in these early days to 
develop this pretty work that we can see actually in the form of the 
Internet.

Actually, I'm searching for documentation about the Bell Datastation 303 
and/or the Dataphone 303. I should like to know what of these devices 
was the used together with the IMP's. I have interest in the proceedings 
to establish connection between the modems of two IMP locations (Calling 
manually from the Dataphone ? Automatic ?) and the status lights and 
sounds involved in the usual work realized by the modem.

I agree in advance all the help that you could provide me, and I'm open 
to give all the help the I could supply in relation with this group.

Regards

Sergio
