Re: HP8924C Memory cards for calibration data in 2024


 

From direct personal experience with these things.

1/ As others have said the 8924C (and 8920B) use PCMCIA cards, NOT the Epson cards.

2/ The cards are accessed in "linear" mode ie addressed like RAM or ROM.

3/ They will READ any type of PCMCIA card, but will only WRITE to RAM or SRAM cards.

4/ PCMCIA to SD card adaptors WILL NOT WORK

5/ SOME PCMCIA to CF Adaptors will work but not many. They need to support linear mode, most only work in IDE mode i.e. like? HDD not ROM.

So Best bet is to get a SRAM PCMCIA card. These can written to in just about any PC that has a PCMCIA slot using suitable software. The sofware of choice was the demo version of Elan's "Memory Card Explorer" MCE. Elan have gone out of business but MCE can be found online.

PCMCIA FLASH cards are variable. All linear FLASH cards can be read in a 8924C. However a lot of them require a 12V supply and most laptops and PCMCIA adaptors don't provide this despite it being part of the specification. Identifying what cards need 12V is difficult as detailed datsheets are hard to find. Again you need MCE or similar software.
