I belonged to LICA (long island computer association) and one of the guys there operated a TRS-80 business computer. I can't remember what model, (II, 12, 16, etc) but it ran Xenix. He had 2 modems and two phone lines at his house connected to it and granted access to club members. I built a micromint 300 baud acoustic coupler kit, connected my TRS-80 Model III to the phone and over to his Xenix machine.

I see that the actual fragmentation is about how each and everyone got 
in touch with computers, personal or mainframe or whatever! Me, I was in 
junior high and usually understood everything in the math class by the 
first 15 minutes, after which I would become restless (bored) and the 
teacher would send me several buildings away to inquire about the room 
temperature of the computer room, which hosted an HP3000 system with 
several terminals (that included primitive graphics capabilities via 
serial connection!).  It was 1978, and I learned BASIC right there. 
Afterwards, it was Apple II and their Franklin clones as a freshman, 
running UCSD Pascal... in 1982.  Later it was the Z80 card in the same 
computers, running CPM, but just for the sake of using the Z80 assembler 
tools.  And we were using also the said Apple II to impersonate card 
readers that would send jobs to the IBM 4381, as a sophomore... My dad 
bought me an HP71B calculator in 1984, and that really was when my 
numerical math skills progressed.  I still do that for a living.  And 
the height of my BS years... getting to run MATLAB in an IBM-AT with a 
math co-processor.  Later, as a teacher, getting my first BITNET email 
account in 1987, learning XENIX, wiring phonenet for the Mac network at 
the university, then as a grad student (1989) using VAX machines at 
UW-Madison, but also Apollo machines, Sun 4/50  machines, and HP-300 
machines... and in1990, I telnet-ed to UCSD to run jobs in a Cray at 
UCSD...  whoa, such memories...
