Zero 88
Sirius 24 (1988)
Zero88's Sirius console arguably did more to democratize memory lighting control than any other product, making it affordable enough for schools and other small venues that until then relied on manual preset desks.
While the price was a big part of this, it was also that Sirius presented a familiar operating environment of twin banks of 24 faders (if you wanted to you could still run it manually), but then with the ability to store up to 99 memories with programmed crossfade times, or six other looks onto additional submaster faders. A key-switch allowed access to the desk's functions to be limited to program, preset or run only.
Zero88's design team based the console around Motorola's 68B03P processor coupled with 32K of RAM. Output was originally 10V analogue, but a later mk2 version added support for DMX as well as for point memories between existing cues!
Finally retired in late 2000, Sirius set the tone for subsequent generations of Zero88 consoles which repeatedly made new technology - memory, then later moving light control - accessible and affordable.
