Back in the sixties when Federal Systems was big, I seem to remember graphics on TI/HP terminals with oscilloscopes as screen via acoustic couplers no less. Later there were graphic accelerators that went thru the 5088. Haven't looked in a while but there was an option in PARMLIB for graphics support. Back when Bill Butterfield/GMR was head of SHARE one of his merry men gave a talk on their environment. It was a big 600j with a good bit of graphics. Don't remember the specifics but maxusers on TSO was 6. In a message dated 11/26/2017 2:43:55 PM Central Standard Time, [email protected] writes:
APA = All Points Available (or Addressable), which would allow any dot on the screen to be set by the host. I assume that means I could send special codes to the screen to say, draw a (real) line or arc, or maybe just send an entire block of bits to the screen. And I think I read this function was never available on any real IBM hardware, only on emulators. ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
