more lucrative e-business (integrated e-commerce and Internet technology solutions). Aptiva models The series to which a Pentium-based Aptiva belongs is encoded in the first letter of the three-character model number (so a 2168-M40 is an M Series). The word in quotes relates to the internal development name for the computer. A Series Followed the M series Aptiva. Also used Mwave adaptor and Windows 95. C Series "Courageous" There were two model types and followed A series Aptiva. E Series L Series M Series "Magic" First Aptiva series preloaded with Windows 95.

Aptiva machine types: 2134, 2136, 2137, 2138 2140, 2142, 2144 2151-89E, 2151-90E, 2153, 2156, 2158, 2159 2161, 2162, 2163, 2164, 2168, 2170 (AMD K6-2), 2171, 2172, 2173, 2174, 2176, 2178 2193, 2194, 2196, 2197, 2198 2255 2270, 2274 6832 6864 The first generation of Aptivas used the 2144 desktop and 2168 tower unit form factors. The 2159 "stealth" series was a unique all black design that had the monitor resting on a metal stand with a 'console' located underneath which contained the floppy and CD drive. The console connected to the main unit via a 6-foot cable. Later in the production life, all Aptivas used tower unit form factors. Originally the 2144 and 2168 machine types referred to the amount of open slots and drive bays. Later machine type numbers did not have the same nomenclature. User groups Various Aptiva user and fan groups emerged. One of the most notable and tenured was run by Don Schneider, "DON5408's Unofficial Aptiva Support Site", now available on aptivasupport.com. The site had much information on topics such as how to open the computer case, drivers and upgrade tips. The site included a user chat group on Friday nights for users to help each other with PC issues. The site was removed when AOL discontinued its web hosting services, but some pages still remain on ptd.net. The site ran from 4/4/1997 to 10/31/2008, bringing in just under a million views on the home page.
