Before 1996:

TTS/PAPER (the Trouble Ticket System) ran on two mainframes from
Digital Equipment Corporation.  These PDP-10 computers, model
KL-1090, were accessable via the Tymnet Packet Network as
Tymshare hosts 23 and 26.  Each computer was the size of 5
refrigerators, and had a string of disks that looked like 18
washing machines.  Their power supplies produced +5 volts at 200
amps (non-switching) making them expensive to operate.

The PDP-10s ran TYMCOM-X, an offshoot of TOPS-10 modified for Tymshare.
The application was written in FORTRAN and used the 1022 database.

After 1996:

The DEC PDP-10s were replaced by PDP-10 clones from XKL PLC.
They were accessable via TCP/IP as ticket.tymnet.com and
token.tymnet.com, by both TELNET and HTTP.  A low-end
workstation from Sun Microsystems was used as a telnet gateway;
it accepted X.25 logins from the Tymnet network and forwarded
them to "ticket" and/or "token".  (The workstation is labeled
"conductor" in the pictures above.)

The XKL systems ran TOPS-20.  The application was ported to a newer
version of the FORTRAN compiler, and still used the 1022 database.

After 1998:

Both systems have been put into storage, in the hopes that
someday they may be useful again.
