HP20s End of Production



#4

Certainly someone in this forum knows the end date of HP20s production. Do you also know when the colour scheme was changed from blue/yellow to the HP48g low contrast colours? We had a similar discussion about the HP32sII earlier.

Thanks in advance for your response!

Sorry, I find no answer neither in hpmuseum.org (HP20s is too new for this site) nor in hpcollection.org (there is just a question mark). But AFAIK these calcs are not produced anymore. So I assume they ended together with HP32sii and the change of colors was made together with HP32sii, too. Who knows ?

The color change for the 32SII is thought to have occurred in 1999, and the 20S may have changed at that time as well. See the following thread:
