RamBOX - Matthias - 07-20-2003 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? Re: RamBOX - Emmanuel, France - 07-20-2003 dear matthias, Re: RamBOX - Raymond Del Tondo - 07-20-2003 Hi,
maybe in some PPC Technical notes are some hints. PPC Journal CD's ? Or perhaps Meindert has an idea ? ;-)

Re: RamBOX - Matthias - 07-20-2003 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...
Re: RamBOX - Emmanuel, France - 07-20-2003 I have a W&W 32K RSU too. Re: RamBOX - Meindert Kuipers - 07-21-2003 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.

Re: RamBOX - Christoph Klug - 07-21-2003 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...
Re: RamBOX - Meindert Kuipers - 07-21-2003 Christoph, Can you actually make the ZEPROMS or just program them?
Meindert
Re: RamBOX - Grant Goodes - 07-21-2003 Yeah, my question exactly. I have a dual-Zeprom
grant..
Re: RamBOX - Matthias - 07-21-2003 Cool, and I'm looking for a ZEPROM burner and do not get on.. ZEPROMs I have some....
Re: RamBOX - Raymond Del Tondo - 07-21-2003 Hi Matthias,
too late. I used to have a very huge Zengrange ZEPROM programmer with 8 (EIGHT) ZEPROM module slots.

Re: RamBOX - Matthias - 07-21-2003 Grrrrrrrrrrrrrrr........
Re: RamBOX - Jeff - 07-21-2003 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?
Re: RamBOX - James - 07-22-2003 Quote: I suggest you use an 8 bit SRAM chip in place of two 1 bit chips, and waste 6 bits (tie them to ground, perhaps through a resistor). HTH,
James
Re: RamBOX - Peter - 07-22-2003 Don't say so, Matthias,
