Is it possible for anybody to rebuilt a RamBOX, so that this powerfull instrument would become a Xmas present for some of us? What would be the problem for this?
I know that there are some hardware designers like Christoph Klug that could perhaps built this...
I would buy it...

Hi,
maybe in some PPC Technical notes are some hints. PPC Journal CD's ? Or perhaps Meindert has an idea ? ;-) Raymond

Is a opened RamBox not enough? You only need the plan of the print, do you? Second you need a system software... W&W is ok...

I have a W&W 32K RSU too.

Do you mean to rebuilt an original old design? I am working on a completely new design that is a RAMBox! See the specifications at www.kuipers.to/hp41. Meindert

Dear Meindert, It makes much sense, that you complete your actual design (working with modern technologie and parts). Rebuilding existing Eramco or W&W Ram-Box solutions is too much work and some storage IC parts not available today or exotic and hard to find. The "traditional" Eramco and W&W Ram-Box solutions are absolutely nice parts for active HP41 user and for any collector. Unfortunately Ram-Box systems hard to find. Up to now (and for future times) Zeproms are the leading solution for concentrating maximally power in only one HP41 plug in port...

Christoph, Can you actually make the ZEPROMS or just program them? Meindert
07-21-2003, 10:30 AM
Yeah, my question exactly. I have a dual-Zeprom grant..

Cool, and I'm looking for a ZEPROM burner and do not get on.. ZEPROMs I have some....

Hi Matthias,
too late. I used to have a very huge Zengrange ZEPROM programmer with 8 (EIGHT) ZEPROM module slots. Raymond

Grrrrrrrrrrrrrrr........

I am currently building the old version of the MLDL posted in the PPC Journal some years ago. The only IC's that I cannot find are the 4k x 1 Static Ram, TC5504AP-2. Does anyone know where these can be found?

Don't say so, Matthias, -peter |
