Pioneer Variants Message #1 Posted by Mark Hardman on 15 Nov 2013, 3:23 p.m. Here is a list of original Pioneers along with variants that I know of. Without considering ROM versions, are there any that I have missed? Model Variant ----- --------------------------------------- 10B Black face plate w/green legends 14B 50 Year Anniversary 17B - 17BII Black face plate 20S Black face plate w/green+purple legends 21S - 22S - 27S - 32S 50 Year Anniversary 32SII Black face plate w/green+purple legends 42S Indented bezel

Re: Pioneer Variants Message #2 Posted by Randy on 15 Nov 2013, 10:40 p.m., in response to message #1 by Mark Hardman The 22S, 27S and 32S were made with both the earlier flat and later recessed bezel versions. Another variation is molded versus printed key tops. Anything made after 1997 had printed keys which included the 10B, 17BII, 20S and 32S. While the 42S was made in Indonesia until 2000, it never had printed keys. The 17B and 27S have appeared as pre-production units with different key legends on the top row. The 27S had its name changed from "Technical Manager" to "Scientific" before it went into full production. That adds up to the 10B, 17BII, 20S, 27S and 32S each having three variations.
