- NWG/RFC #398 John R. Pickens
- UCSB Online Graphics Edward D. Faeh
- NIC 11911 UCSB
- 22 Sept 72
-
- At present, users with TEKTRONIX or IMLAC terminals or with systems
- that support the proposed level 0 graphics protocol can access UCSB
- graphics. Listed below are the ICP sockets for the currently
- supported terminals and protocols. Any detailed questions about or
- problems with a particular protocol should be directed to Ed Faeh
- (805-961-4047).
-
- Socket Supports
-
- x'701' IMLAC with special software designed
- by Jerry Powell (MITRE Corp.).
- Graphics is sent over a simplex
- connection to the IMLAC. Alphanumerics
- are sent over a TELNET-like connection
- to a separate device. The IMLAC
- software can be loaded from MIT-DMCG.
-
- x'703' IMLAC with 80x80 display grid
- and Standard Text and Edit Package.
- Some IMLACs have a 64x64 display grid.
- Therefore, the choice may be made in
- the near future to format the
- graphics output from this connection
- for the smaller grid resolution so
- that both terminal types may be handled.
- Display resolution is limited with
- this terminal configuration as
- normal UCSB terminals have 1024x1024
- grid. Nevertheless, meaningful
- displays are obtained even at the
- lower resolutions.
-
- x'705' Current Level 0 graphics protocol.
-
- x'707' Same as x'701' but with special
- UCSB online keyboard as input.
- This configuration averts the
- necessity of spelling out online
- operators.
-
- x'709' Same as x'705' but with special
- UCSB online keyboard as input.

- UCSB OnLine Graphics
-
-
- x'801' TEKTRONIX terminals. Models 4002-A
- 4010, and T-4002 have been tested
- successfully. Presumably all other
- 4002 compatible terminals will also work.
-
- The primary problems that will be encountered by the network user
- center about display formatting. For historical reasons (i.e. only
- one type of terminal in house ) no means were included in the system
- to facilitate terminal independent random positioning of alphanumeric
- output. Thus, a program which draws and labels a graph neatly on one
- terminal might label like a kindergartener on other terminals.
- Nevertheless, this problem can be minimized with careful programming
- and efforts are underway to provide at least minimal alphanumeric
- device independence.
-
- Users interested in experimenting with online graphics should contact
- John Pickens (805-961-3454), Glen Davis (805-961-2462), or Mark
- Krilonovich (805-961-3454). Suggestions and criticisms of all aspects
- of the UCSB OnLine - Network User interface are desired.
