200LX Ram cards compatible with 48GX? Message #1 Posted by mr-scorpio on 11 Nov 2011, 8:03 a.m. Does anyone know whether the Ram cards that go in the 200LX (palmtop) are compatible with 48GX ? They appear to be similar? Hope someone has the answer Best Al

Re: 200LX Ram cards compatible with 48GX? Message #7 Posted by Raymond Del Tondo on 11 Nov 2011, 7:40 p.m., in response to message #6 by Thomas Chrapkiewicz The cards for the HP-48 (S/G) are 8bit, but there were 16bit cards for other devices. Slightly OT: Back then at W&W we used a Sprint Plus full size ISA card and software to burn OTPs and EPROMs for the HP-48, and I still have my Needham's Electronics PB10 EPROM burner with a special dual socket for these 8 and 16 bit JEIDA cards.
