For model 2/bis for example. What the heck does "bis" stand for anyway? Is it the plural of bi? A computing acronym I've never heard of? Latin for twice? Polish for encore?
Just wondering if there is a official word on this.
Thanks!
MiG-21bis (1972; Izdeliye 75; NATO "Fishbed-L/N"
The ultimate development of the MiG-21, fitted with the Tumanskiy R25-300 turbojet engine and a great number of other advances over previous types. Those MiG-21bis for the Soviet PVO (Air Defence Force) were equipped with the Lazur GCI system (NATO: "Fishbed-L"), while those for the Soviet Air Force were fitted with the Polyot ILS system (NATO: "Fishbed-N").
MiG-21bis (Izdeliye 75A; NATO "Fishbed-L")
Lazur-equipped version with a slightly different avionics package exported to some Warsaw Pact countries. In Bulgaria and East Germany these were designated MiG-21bis-Lazur.
MiG-21bis (Izdeliye 75B; NATO "Fishbed-N")
Polyot-equipped version with a slightly different avionics package exported to some Warsaw Pact countries. In Bulgaria and East Germany these were designated MiG-21bis-SAU (SAU referring to Sistema Avtomaticheskovo Upravleniya = "Automatic Control System"). This variant was manufactured under licence by HAL in India from 1980 to 1987.
MiG-21bis-D
D = Dorađen ("Upgraded")
Upgraded in 2003 for the Croatian Air force with some elements of the Lancer standard. Modernized for NATO interoperability including a Honeywell ILS (VOR/ILS and DME), a GPS receiver, a new IFF system and communications equipment from Rockwell Collins.
MiG-21bis/T
T = Tiedusteluversio ("Reconnaissance Version")
Finnish designation for MiG-21bis modified to carry reconnaissance pods.

http://en.wikipedia.org/wiki/V.22bis said:Note: the bis and ter suffixes are ITU-T standard designators of successive iterations of a standard (bis and ter are derived from the Latin for "twice" and "thrice").
BIS is a Russian acronym meaning "large-scale integrated circuit".The only place I've seen "bis" used on a semi-regular basis outside of Traveller is in Soviet/Russian military equipment, where it is applied to improved and more-capable models of aircraft, etc.

Thus, a Model 2bis computer is an improved Model 2.
Thus, the AV-8B Harrier II* could be termed the "AV-8bis".
* The AV-8A and the AV-8C (upgraded AV-8As) were named Harrier. The Harrier II was actually a new airframe closely related to, but incorporating very little structure from, the AV-8A/C.
Actually blame the whole thing on the French who started using the system in WW1 to designate various sub types of aircraft.
As in Nieuport 17 and Nieuport 17Bis
Frankly I don't know why MM did that. It seems all too unnecessary. Hell, why not just keep going: bis, ter, quater, quinquies, sexies, septies, octies, nonies, decies, undecies, duodecies.....AAARRRGHHH!!
In UK Government circles BIS stands for [Department of] Business, Innovation and Skills.
But if this were the derivation, then the BIS version ought to have inferior functionality to the standard model, not superior :rofl:
The Apple II and II+ were expected to be succeeded by the Apple III, but it tanked in the market and the II line continued (//e, //c, IIgs). MWM's Challenge column "Using your Model/2bis" is an obvious play on the term, as the program listings provided were for the Apple II line...
I have no clue what the S stands for in iPhone models.
The G in 3G stands for "Generation" and 4G - referring to the data protocol speed.
