RE: HHC2021 Bob's Calculator Challenge
Thanks a lot for this Andi,

I couldn’t make the link work at first, but now all is good.

I was quite sure that the 28c was about a year before the 28s came out - the 18b was introduced mid 86. in the fall that year I had a chance to peek into the - not completed - 28c manual. Most can imagine the reaction I had. Same package as the 18b and then symbolic algebra, graphics, RPL and all the new stuff.
