To execute a program in extended memory it must first be copied to regular internal memory. This code-exchangability created a huge base of programs.

Type, Precision, Input Mode. Specifies the amount of number registers nnn to allocate. The HPA quad manul module added registers giving a total of registers. Data inside extended memory is organized in mxnual which can store programs or data. A HPCV with h-41cx extended manuql, a built-in timer module and the extended functions module.

Cardboard box with 6 rolls of paper for the A or A printer. Front and back close to mint, a few scratches on the sides. Replaced the rubber wheel – now it doesn’t work any more at all! German, pages, A unique feature was the barcode reader “wand” that allowed to read in programs that were printed on paper in the form of barcodes. After the listing has been stopped when this “END” manuual displayed switching to PRGM mode will display the program and it is possible to delete it step-by-step to reclaim program memory.


One sheet of sticky labels for overlays, completely new. All keys could be re-assigned to user-defined commands. White keyboard overlay with normal function codes. Rather large with no other markings. The “flying goose” and the “backwards flying goose”. Unfortunately, my cleaning efforts made things even worse not visible on the picture.

The graphics display of some of the Pioneer models is much better in this respect. One register can hold up to 7 program steps 7 bytes. Refer to the table on the back of the calculator for special keys ie.

Hewlett Packard HP-41C/CV/CX/CL

Register memory shared with program memory. Infrared module HPA, serial number Also, it is not possible to use “CLP” to delete the memory occupied by the program! B, Septemberprinted in Singapore. Delivers highly accurate results! Mint out of the box, everything like new except the cardboard box. Within a program local labelsA – J and a – j can be used. To enter this command press: This early HPC unit is equipped with golden ball-contacts for the external power supply.

Up to four such modules could be added to reach a total of registers. Bound printout from the pages at hp Rather, indirect access must be used. Older units will be completely reset, newer units perform a “soft reset”. The HPA “X-memory” module increased the extended memory space by registers bytes.

The following files are available on the Systemyde website: Various information on “synthetic programming”. Large battery pack or external power supply. Math 1 ROM module, part no. One one side marked “”. Did not put back the label which covers the screws. These local labels are not visible outside of the current global program. Note that two extension port covers have been ,anual with a black pen hardly noticable.

No scratches on the back, keys feel a bit worn from extensive use, front dirty seems someone glued a keyboard overlay to the unit.

Allowed for “synthetic programming” where machine code was accessible thru illegal commands. And although it looks modern it is rather slow.

One blank overlay, one standard functions overlay both plastic. None powered from HP calculator. It is also one of the first calculators with support for alphanumeric strings – but in my opinion this makes the display hard to read.
