This short letter offers an interesting perspective of the DEC Professional in the late 1980's. Being that many DEC machines are still functional today it would be very believable that a person would choose to continue to use their UNIBUS system, especially an 11/44 into the 1990's. If I was to guess I'd say this letter was published in early 1987. Reply  |
