Does anyone know if the U-lowel or DMI or Ameristar add-on graphics boards let you use a real Workstation monitor, as opposed to the tiny Commodore 1950. I am looking for something where I can have 4 full sized xterms, or whatever, on the same screen. You know, like a real Unix workstation. Something like a 19" Sony Trinitron monitor.
