HP41 Emulator card for HP48 series

[rprosperi]

Thanks for these detailed notes Raymond. Was the GX version marketed under the same model number and how can one tell which version will work on the GX (or is it both SX and GX)?

I have a card that reports "0E" for the response to the VERS41 command in the Ctl41 Library. Seems to be SX only. Copyright on the card is Zengrange, 1990.
