> My first home computer (1975) ran a Teletype ASR33...

Actually my first computer was a 6502 + 6522 TIM? (I forget the part 
number) hooked to a borrowed ARS33.  The guy had to have it back so I 
built a "glass tty" from a book, was it Lancaster?  that I used after 
that.  Used a monitor and a surplus keyboard.  Had a whopping 1K of 
memory.  The whole thing was wirewrapped.  The glass tty didn't scroll 
but had two display pages so I could swap back to the previous page to 
see what had transpired.  Then I got a KIM-1.  Added a KIMSI adaptor to 
it and a tarbell disk interface and wrote a DOS (Disk operating system) 
for it.  Looked a lot like the OSI-65 OS since that was the only one I 
knew anything about.  I started developing a DOS that looked like CP/M 
but decided to just give up and buy a Z80 system and run CP/M.  The rest 
is history.  I still have the KIMSI and two Kim-1 boards. 

You are not the only geezer onboard.

Jim.
