I've never heard of the HP Digital Slide Rule. Do you have photos and/or more details? I am familiar with the first HP desktop calculator (9100A) that inspired their first handheld calculator (HP-35). The HP-35 was a ten-digit calculator that was released in 1972 for $395. -----Original Message----- From: Van Snyder via cctalk <cctalk(a)classiccmp.org> Sent: Tuesday, April 16, 2024 9:34 AM To: General Discussion: On-Topic and Off-Topic Posts <cctalk(a)classiccmp.org>rg>; ED SHARPE <couryhouse(a)aol.com> Cc: Adrian Godwin <artgodwin(a)gmail.com>om>; Van Snyder <van.snyder(a)sbcglobal.net> Subject: [cctalk] Re: Bomar 901b My wife found in my stuff.
