Well the frogs never were usable as a async ASCII terminal.. for some reason I think they were intended for IBM... The white later ones with detachable large keyboards definitely were for IBM and were used with a cluster terminal controller if memory is correct... if they were ASCII were sync not async? My memory escapes me at this point except for the fact none of us could use them and we call scrapped them! In a message dated 8/14/2016 3:36:00 P.M.

Heh, that sounds like the description of the Hazeltine terminals we were forced to use on a long-ago project. The vertical hold ... didn't. It was plus or minus 2. After using the monsters for an hour or so you had to go walk outside until your own vertical hold settled down. I imagine anyone who easily got seasick could never had used them at all. mcl
