Only 1 coax cable to a 3290. It was a DFT device (distributed function terminal). They were more of an SNA device and not sure they functioned as non-sna from what I remember

So it ended up in the tape room where it saved desk space by combining consoles for 3 LPARs with a single TSO session. I'm pretty sure it had 4 coax cables, so in that mode the vertical split was not used. Like Ed mentioned, I remember watching the text paint itself on the screen as it arrived. Since the plasma only had one brightness level, highlighted text was underlined instead. In addition, I seem to remember the underlines appeared in a second painting scan after all the text had already finished painting. By coincidence, a week ago I received my monthly Model Aviation magazine and there's a new transmitter featured that seems to have stolen the 3290 color: https://linkprotect.cudasvc.com/url?a=https%3a%2f%2fwww.modelaviation.com%2fsites%2fdefault%2ffiles%2fImport%20Model.JPG&c=E,1,0e94sjqD6wpOaLrccRG_7BPo1mWmikGmSGQ3eTyyej2fPLdWxDbP2UZuYjREHrhTHYEbU9GRDXecXgpoGlYNIGCeeNu5QgSQuL2dKgl-01cMpCOBIB8Zhoc,&typo=1 On 4/16/2021 2:47 PM, Steve Smith wrote: The 3290 added what I think was called "DFT", or "partitioned mode" to the 3270 protocol, and allowed a smart application (afaik, ISPF is the only application that smart) to divide up the screen into several logical screens. The ISPF SPLITV command implemented that. Maybe some TN3270 apps can support it, but I haven't explored it, as multiple sessions are better anyway. I used a 3290 for a while in the Naughty 90s, and liked it, except for the orange display. The 3290 was a gas-plasma or something like that, so the color was chosen by physics, not aesthetics. sas On Fri, Apr 16, 2021 at 4:47 PM Ed Jaffe <[email protected]> wrote: On 4/16/2021 1:43 PM, Bob Bridges wrote: Somewhere in the dim reaches of my past I think I saw mention of the ability to split an ISPF screen vertically rather than horizontally. I've never tried it, and I'm not sure I didn't just imagine the capability. I used to have a 3290 "gas" panel display that had this feature. The text was always orange, did not display high-intensity characters, and painted very slowly. But, it was kinda cool nonetheless. -- Phoenix Software International Edward E.
