Re: Rambox battery replacement ( edited again on Oct 17, 2007 07:29 GMT ) Message #2 Posted by Antoine M. Couëtte on 15 Oct 2007, 4:16 p.m., in response to message #1 by Prabhu Bhooplapur
Dear Prabhu,
The following will detail to you how I managed to save and run all my software developped on a RAMBOX. It may not be the exact answer to your current problem ( internal battery replacement ) , but it offers a way of getting around it.
A few years ago I was in a situation quite similar to yours : I needed to have one HP41CY ( i.e. a HP41CX with an internal RAMBOX II version with 64 K ) repaired. It was not a question of internal battery replacement, but it was a faulty and erratic behavior with a suspected internal wiring degradation which definitely required internal repair.
The following describes the way I solved my HP41CY / RAMBOX II problems in a totally unexpected way, which eventually has been MUCH BETTER than a simple product repair and exceeded all my expectations thanks to the highly dedicated work of a few Men as described hereunder.
If you proceed like I did, maybe it will help you as much as it helped me.
*******
As you know RAMBOXes were manufactured by the German Company W & W Software Gmbh. When I needed a RAMBOX II repair some 5 years ago, Wilfried Koetz the Manager of W & W Software Gmbh indicated to me that W & W had stopped supporting the RAMBOX.
As I had extremely important software on my Rambox II - a software I had taken some 3000 hours to develop - I had to find an urgent solution ...
You will find HERE THE ENTIRE STORY
******
AS A SUMMARY :
The here-above story describes how I solved my RAMBOX II problems in a totally unexpected way, which eventually has been MUCH BETTER than a simple product repair.
In other words : if you have the possibility of using one of the existing available " HP41 Simulators " which 100% replicate the 64 k RAMBOX I/II, you should then be able to run all your own Software existing to-day on your RAMBOX.
In my own case, I am fully indebted to both Jean-François Garnier and to HrastProgrammer. As the STORY herebaove goes, and simply because I requested some help from them , Jean-François greatly improved his former EMU41 into fully replicating
the full 64K RAMBOX II and making it available to the Community. And on his side HrastProgrammer went into developping for me a taylored version of his HP-41C Emulator for HP-48GX/49G into a Version with a total of 92 K - including a full replica of the 64K RAMBOX II.
True .. you would need to get a HP48GX with some memory cards, or a HP49G ( or a HP49G+ or a HP50 : Please HrastProgrammer correct me if the references to HP49G+ and HP50 are not correct ) if you want to have a HANDHELD replacement of the Rambox I / II ... ( see HRASTPROGRAMMER SITE and in particular HP-41C Emulator for HP-48GX/49G ) .
... but if all you want is keeping a record of your
Programs working on a laptop - at a speed of over 500 times a real world HP41 - then Jean François Garnier's superb " EMU41 running on PC " is a wonderful choice ( see EMU41 )
Hrastprogrammer's HP41 X/Y/Z - under the Version developped specifically for my own needs as described in the STORY hereabove - and Jean-François Garnier's EMU 41 emulators are the only 2 emulators I know of which fully emulate Rambox I / II .
I am not aware of any other such emulator ( i.e. replicating the Rambox I / II ) . But should one exist, its existence will likely be confirmed to you on this forum by any qualified Expert reading this thread.
I hope this information will be useful to you.
Best Regards from
Antoine
