`
`In the summer of 1978, Serial Dialin lines were made public to use the Honeywell mainframe at the
`University of Houston. Prior to this time dialins were available for in house use only.
`7419840 at 300 baud.
`7419680 at 300 buad.
`
`In the spring of 1979, another Serial Dialin phone number was made public to use the Honeywell
`mainframe.
`7419490 at 300 baud.
`
`In the spring of 1981, This Serial Dialin phone number was moved to the new DEC 11/780 named
`UHVAX1.
`7419680 at 300 baud.
`
`In February of 1982, another Serial Dialin phone number was made public to use the NAS/9000
`mainframe.
`7417220 at 300 baud.
`
`In the spring of 1983, another Serial Dialin phone number was made public to use the NAS/9000
`mainframe.
`7419875 at 300 baud.
`
`In January, 1984, BITNET came to the University of Houston.
`It was a point to point network.
`UH was downstream from RICE and upstream from A&M.
`
`In the spring of 1984 UH started a broadband computer network based on Sytek Corp.'s Sytek boxes.
`This replaced the previously used point to point wiring.
`This allowed many serial line connections to be established between computers using the same
`coax cable system.
`A few months later a compliment system was added that was developed by AgelNet. It was
`compatable with Sytek but used flat ribbon cable instead of coax. This made for easier installations
`especially inside the DEC Vax computers.
`
`In October of 1985, DEC servers and ethernet began to replace the Sytek network.
`
`In the spring of 1986, other Serial Dialin phone numbers were made public to use the Sytek Network.
`7909717 at 1200 baud.
`7963800 at 1200 baud.
`
`In July of 1986, a USENET connection was made to the 3B20s. This made the Usenet News
`available.
`
`In 1986 TexNet came to UH. It is a DECnet based network
`It's name was changed to THENet which stands for Texas Higher Education Network
`It was started by UT. UH & A&M joined as well as other Texas Universities
`
`In March of 1987, the 300 baud Serial Dialins using phone number 7417220 was discontinued.
`
`In July of 1987, SesquiNet became operational

`
`It was started in the spring of 1987 by Rice University. It was named after Texas's sesquicentinial
`anniversary. A grant from the National Science Foundation allowed the project to get started.
`The original members were Rice, Baylor College of Medicine, Houston Area Research Center,
`Texas A&M, Texas Southern University and the University of Houston.
`It brought full blown internet to UH. Previously you had to use a gateway from one of the other
`networks to access internet.
`
`In Summer of 1988, Kinetics boxes and Gater boxes were used to bridge localTalk (Apple's appleTalk
`protocol) to the ethernet. This allowed campus wide Macintosh communications including:
`remote laserWriter printing
`remote file sharing
`remote talking via Broadcast
`
`In Fall of 1988, AlisaTalk was installed on the Jetson Vax cluster. It allows appleTalk between users
`of the Jetson Cluster and Macs on the network.
`
`In the fall of 1988, I started a Macintosh File server on the Jetson cluster using AlisaTalk so that Macs
`on the network could easily download Software by simply mounting the remote public disk with
`appleShare and dragging the files that they needed to a local disk. They could also, if they had an account
`on Jetson, use part of their Jetson file space as a remote disk from their Mac to store mac files. It also
`made it easy up/download files to/from the Jetson cluster.
`
`In August of 1989, Usenet News was installed on the Jetson Vax cluster.
`
`In the spring of 1990, I started a Macintosh File server on a unix machine named "lavaca" that used
`Columbia University's CAPS Package (Columbia AppleTalk Protocol System for unix) which started the
`ethernet zone "Twilight" for etherneted Macs. Lavaca was a DEC machine that ran ULTRIX.
`
`Prior to the fall of 1991, Serial dialin lines were:
`7497700 to 7715 at 1200 baud were Sytek ports
`7497716 to 7759 at 1200 baud were DECserver 200 ports
`7417220 to 7229 at 2400 baud were DECserver 200 ports
`
`In the fall of 1991, Serial dialin lines were changed to:
`7497700 to 7739 at 1200 baud were DECserver 200 ports
`7497740 to 7749 at 2400 baud were DECserver 200 ports
`7497750 to 7797 at 19.2 K baud were Xyplex LAT & TCP/IP ports
`
`In the spring of 1993 I installed the ARNS (A Remote Network System) written by the University of
`Melbourne on menudo. This software allowed a user to use the AppleTalk Protocol over a serial line
`(dialin) or over an IP protocol connection. This allowed a home user to mount an appleShare volume on a
`Mac at work at home over a dialin. You could also print to networked printers here a work from home.
`You could also run MacTCP on top of ARNS over a serial line so you could also run any of the IP
`services (internet) at home over a dialin. A great step forward in Mac remote use.
`
`On March 30, 1994, BITNET was discontinued at the University of Houston.
`
`In the spring of 1994, UH began a CWIS (Campus Wide Information Service) using the University of
`Minnesota's Gopher software. This included links to the x.500 staff & faculty directory that previously
`was accessed using the WHOIS command on main frames or x.500 application software on workstations.
`
`In the spring of 1994, Serial dialin lines were changed to:
`
`Page 3 of 4
`
`
`
`7497700 to 7749 at 14,400 baud were Xyplex LAT & Telnet
`7497750 to 7797 at 9600 baud were Xyplex LAT & Telnet
`
`In the fall of 1994, UH began a WWW (World Wide Web) root server which has links to UH's Gopher
`Server. This included links to the x.500 staff & faculty directory that previously was accessed using the
`WHOIS command on main frames or x.500 application software on workstations. Workstations using
`NCSA's Mosaic or freeware Netscape clients could now use graphics and sound as well as hypertext to
`browse information.
`
`In the spring of 1995, UH started a project to have dialin PPP (Point to Point Protocol) service available
`to all Faculty, Staff and Students by the fall. I headed up a network subcommittee to study this project.
`During the summer I wrote a Mac timer application that used applescript to interface with MacPPP and
`freePPP to allow a user to time his PPP session and warn him when the time is up. This was needed
`especially for the express pool which has a 30 minute connect limit.
`
`In the fall of 1995, Serial dialin lines were changed to:
`7497700 to 7749 at 14,400 baud were Xyplex LAT & Telnet
`7497750 to 7797 at 9600 baud were Xyplex LAT & Telnet
`7491200 at 28,800 were Xyplex LAT, Telnet and PPP with 8 hour timeout, userid required
`7497973 at 28,800 were Xyplex LAT, Telnet and PPP with 30 minute timeout, userid required
