Advanced Tools
- reMarkable - “The next-generation paper tablet. Replace your notebooks and printed documents with the only tablet that feels like paper”.
Simple Tools
- My LCD writing pad “REFLECTS-GÖTEBORG, 52451-BK”.
-
- Battery: CR2016 = CR2025: lithium, 20 mm diameter, 1.6 mm height, 3V.
- My feedback:
- “Erase Lock” positions:
- “ON” = Pressing the “Erase” button erases the screen.
- “OFF” = Pressing the “Erase” button does not erase the screen.
- The write-protection “Erase Switch” prevents from erasing by the “Erase” button, but does not prevent writing on the screen. Means if the writing pad is transported in any kind of bag, the pressure of the bad may cause some unwanted drawings on the screen.
- How to transfer the written and painted contents from the writing pad to a PC or smartphone?
- What is the power-consumption a) “Erase Switch” = ON b) “Erase Switch” = OFF?

- “Instead, HP combined elements of RPN, Lisp and Forth and came up with a language called Reverse Polish Lisp or RPL. From Lisp, RPL inherited concepts such as atomic and composite objects, temporary (lambda) variables, garbage collection, the ability to pass unevaluated objects as arguments etc. and from Forth, RPL inherited threaded execution and RPN notation with an unlimited stack”.
- “The HP-28C was the first calculator to be both internally programmed in RPL and to make RPL available to the user”.
- EN.Wikipedia "RPL (programming language)", DE.Wikipedia "Reverse Polish LISP" ( RPL ) - “The last pocket calculator supporting RPL, the HP 50g, was discontinued in 2015”.
