The CV model having 2,233 bytes of ram memory (2Kb) & 64Kb Rom memory. Original retail price US$325.00 (Hp's 1982 price-list).
Our price AUD$300.00
INCLUDED SPECIALS:

# REFURBISHED AS ITS OLD: Had a sluggish 'ALPHA' key - now working correctly. & 2x lower cracked (NOT BROKEN) screw-posts, now glued with Bondic & UV light hardened.
# Valued EXTRAs included: 1x fitted keys-template. An HP41C QREF. 4x NiMh rechargeable batteries for HP41. USB lead to computer, & full installation as a power socket on the 41CV.
ADDITIONAL NOTE: If installing a future upgrade to 'Systemyde' 41CL motherboard which does fit this CV model, please click this button:
The 2nd fitted Mini-USB socket marked 'COPY' in the above image, could be wired-up to allow the data to/from computer link, using the 41CL's 2 pin printer output, motherboard-socket. A visit to systemyde website Manuals page, allows you to download the latest revision details. Download '41CL Calculator Manual, 04/28/2023', to see the motherboard image, & the HP41 plug-in port interface. You would need to buy this accessory to make a link between the calculator & desktop/laptop. But here is the thing, by not using the HP41 port accessory, which does take up 1x port during use, its possible to rewire the wires into the Mini-USB 'COPY' socket instead. This means use of any kind of computer interface could be attached. The standard USB to Mini-USB, being probably the easiest to install & use. Further details would be needed to ascertain which 'COPY' socket pins to attach to which wire. As there are only 2 wires, its a simplish binary yes/no problem! Also the HP41 batteries are likely to run out during data-transfers, the use of the other (lower) Mini-USB socket for mains power from computer to calculator, would prove its weight in gold.

This is like 'do mistake erasure with ease'. When an error has been made with ink or gouache on your work, just use the Pentel brand 'Hyperaser'. Anyone who has done serious commission style work needs tools with a professional edge, this is one of THEM. A retractable eraser made with what appears to be fiberglass and other high erasure content. An unusual effect is that while the ink/paint comes off, the paper/card surface almost totally remains unaffected, (best results on hot pressed papers, cards, vellum skin). Buy one to see for yourself.

KERN PRONTOGRAPH WRITING TEMPLATES.


Sample pictures show the ITALIC style lettering of the 0.35, 0.50 size templates.
Kern Prontograph writing templates are available in 2x sizes. You can use them with these sizes of technical pen;
0.35 tip, 0.50 tip. The style of lettering is slightly leaning, that is, in an ITALIC style.
Actually any brand of technical pen held vertically in these templates will allow writing of the templates lettering. This includes Kern, Reform, Rotring, Staedtler, Erograph etc.
Each template has the CAPITALs, lower case letters, plus most other symbols - like [ ], ( ), ?, +, -, /, * and arrows etc. Another feature of successful neat writing with one of these templates with a tech' pen, is the raised template. It slides above your paper/card on 2 (top & bottom) aluminium rails, this stops wet ink from touching the template as you write. It can also be turned upside down to get reverse characters, with the same effect.
