Note 22
The TIP program has been operated with seven different terminals and with the type 103A modem in the BBN test cell. In addition, users have reported successful operation with four other terminals. The terminals tested are:
- Model 33 Teletype (ASCII code) - tested at BBN.
- Model 37 Teletype (ASCII code) - tested at BBN.
- Infoton Vista 1-H Alphanumeric CRT (ASCII code) - tested at BBN at speeds of 110, 150, 300, 600, 1200, 1800, and 2400
bits per second.
- IMLAC PDS-1 Graphics Terminal used as an alphanumeric display (ASCII code) - tested at BBN at speeds of 110, 1200, and
1800 bits per second.
- Execuport (ASCII code) - tested at BBN at speeds of 110, 150, and 300 bits per second. This terminal differs from the other
ASCII terminals in that delays must be introduced into the computer-to-terminal data stream following carriage-return.
- IBM 2741 Terminal (PTTC code) - tested at BBN. There are at least six possible keyboard code (and matching type element)
versions of this terminal. We have tested one version and provided code conversions for three other versions.
- IBM 2741 Terminal (Correspondence code) - tested at BBN. There are at least four possible keyboard code versions of this
terminal. We have tested one version and provided code conversions for three other versions.
- Hazeltine alphanumeric CRT - tested by a user.
- Telterm 2 - tested by a user.
- Tectran cassette - tested by a user.
- Datapoint 3300 alphanumeric CRT - tested by a user.
In addition to these terminals, we continued program development necessary to interface the ODEC Line Printer (which requires timed delay after paper advance commands), the type 202C modem, and the Honeywell magnetic tape controller and drive. We have also conducted a preliminary survey of "remote batch" terminals, but have not, as yet, been able to resolve the technical difficulties which prevent effective use of these devices with the Terminal IMP.
