The Tektronix 7623 is a 60 MHz analog multi-mode storage mainframe, introduced in 1973. The 7623A facelift in 1975 increased bandwidth to 100 MHz. The 7623B version, specified at 100 MHz, added a reduced scan mode to increase stored writing sped. It replaced the 7613, 7623A and 7633 in 1991. There was also an R7623(A,B) rack-mount version.
