<console interface.

The 7220 was introduced early 1980 and volume ships were 5 months later. By 1983 it was well on it way to next generation. <Some of these were pretty demanding applications which quickly pointed up <the weakness in using 8-bit computers for multi-plane graphics. They also <pointed up the fact that decent high resolution color monitors cost about a <much as a house . . . well, not quite, but you get the idea. If you bough <one, you'd better keep the box, because you'd need a place to live when you <wife found out . . . We did a multibus baord with the first 7220s and we had a heck ofa time with the monitors as most really could not do the bandwidth and the .042 dot size didn't help! As to using a z80, it was awkward but doable though we designed with a 8086 in mind as we sourced that as well. By late 81 we were running a 4plane (1 megabit planes) graphics CPM86 with 512k of ram. The key was the system was cheap for the time considering it was multibus based. Allison
