Abstract

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).

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.

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, t...
