hp48sx RAM module: what type of battery? Message #1 Posted by andy delano on 8 June 2003, 10:56 p.m. Hello, As the subject states, I want to know what type of battery the RAM modules for the 48 series requires. Is it a CR2025? I found my long lost 32k ram module while cleaning my garage (no wonder I couldn't find it...how on earth did it end up in my garage?...that certainly made cleaning it well worth the while!). I also found my sparcom ME applications pac which I still have the manual to! Thanks, Andy

Don't know about the other brands. I found a set of car keys that had been lost for two years in a box of nails in the garage. Seems it was at the exact height of my five year old, two years prior. I let her play with car keys, but calculators, never. Edited: 8 June 2003, 11:30 p.m.

So the CR2025 has the same diameter, but is much higher. I own a 512KB for my GX and this card use also the CR2016. greetings Thomas

The same battery is used for my 512Kb from Cynox. My 1Mb Klotz card use a CR-1216, much smaller. Raul Edited: 9 June 2003, 8:42 a.m.

Message #5 Posted by andy on 9 June 2003, 11:40 a.m., in response to message #4 by R Lion This 32K ram card was actually sold by Smith Corona back in 1990-91 for their electronic type writers. They were a lot cheaper then the HP 32K cards and they work just fine (at least they do in my 48sx which has Rev A rom!...first shipment the bookstore received back in 1990). Thanks for the answers...the CR2016 will fit. Andy
