RE: 9114B and HP-41 HP75C
Most likely all your batteries are no good.
The 9114 batteries can be replaced with a Powersonic PS-628 The 2225B battery pack can be rebuilt using sub-C NiCd or NiMH cells (with tabs) Beware the ink cartridge. The ink is highly corrosive and can destroy the print head connector. New cartridges are available that work with standard paper, part number 51604A. For the 75C I suggest using a AAA adapter like this one. https://www.ebay.com/itm/Rechargeable-HP...SwVDpclCst Charge the AAA batteries in a smart charger like a BC-700. The 9114 uses what is known as the LIF format when used with the 41 and 75. LIF utilities for Linux are here. http://www.hpcc.org/datafile/hpil/lif_utils.html However, many of the HP-IL peripherals (printer, disc drive, etc) have been replaced with virtual peripherals that connect via a PC with a USB connection and an adapter. More here. PIL-Box: http://www.jeffcalc.hp41.eu/hpil/index.html#pilbox Virtual Peripherals: http://www.jeffcalc.hp41.eu/hpil/index.html#ilper https://hp.giesselink.com/hpil.htm https://github.com/bug400/pyilper You can't run 41 programs on the 75 but you can run FORTH. Dave Edit: If you plan on using the linux utilities you will need a PC with a vintage floppy drive controller that can process low-level commands in order to read/write the discs. Additionally, many of the pyILPER utilities are based on the LIF utilities for linux and naturally will run under Linux. |
