48gx Memory Cards



#6

I recently picked up a mint condition 48gx for $100 and it's starting to appear that RAM Cards will cost far more than the machine. Is there a good source for these at the moment?


#7

These are pretty hard to come by. There is one guy on the auction site that seems to mfg from some source.

#8

I bought some of them from Oliver Klotz in Germany, about 5 years ago. I don't know if he still makes them.


#9

I also bought some HP 48GX RAM Cards from CYNOX Germany some five years ago ( http://www.cynox.de/index_e.htm ).

Until now I have been extremely happy with these Cynox made HP48Gx RamCards.


Best Regards to all

I can give a little perspective. I wound up buying a 1 MByte SMI card last November for $170, but you may eventually do better. Shipping between US and Europe usually ruins the deal, so I had mine shipped to my brother in the US. The previous August, I got a 128K HP one for £49 ($75) shipped locally in Britain. Bear in mind that these prices are a lot less than when originally released. They were always more than the calculator (about the same for 128K).

It's a question of waiting, I think. Stay away from the 'built-in battery' types, as these will require surgery when the old batteries stop taking a charge. Also stay away from seller 'coburlin', although his prices are at least three times too high anyway. He also sells 'GRID' cards as 'for 48GX'. These have a nasty low-voltage detector that can ruin the calculator.

There are a number of sellers who have bought up a lot and are dribbling them out at 'collector' prices, but occasionally, someone shows up who just wants to auction one they own. You may do best buying a whole combination of calc and cards from one of these real owners, then selling on what you don't need.

I haven't seen the current manufacturer -- there is an 'OEM' from Singapore, but that again is expensive, and with a built-in battery.

Use lots of combinations of hp48gx, 48gx, hp 48 gx, hp48, etc to search. You do want one for the GX as opposed to 'bank-switched'.
