Anyone want a rambox (made) for the hp 41? - don wallace - 10-02-2005 Wondering how nay if any would like to experiment with
There are some solutions around but they latch up occassionally I am interested in building an enhanced copy of the old ERAMCO RAMBOX. I might make a few if anyone wants one. I am planning to do a little MCODE programming on the 41, so I feel I need one ;-)

Re: Anyone want a rambox (made) for the hp 41? - Meindert Kuipers - 10-03-2005 Don, With all due respect: with Clonix, MLDL2000 and efforts underway by others I do not see why there would be interest in the good old Eramco RAMBOX. Playing with mcode can be done on the simulators as well. And about lockups: programming mcode is almost a guarantee for locking up your calc!

Regardless of the cause (hardware glitch or software bug)
There are enough examples of human fallability in the real world. The answers to your question are:
RELIABILITY and PRICE ;-)
I do want to politely make the point that I am only interested in practical applications for this regretably ancient machine. If others want to work on extending it I think that is JUST WONDERFUL! Thanks to your work Meindert and Diego D. and John I. and many others we have these marvellous gadgets. They are GREAT, but they are not perfect. I am only coming up to speed fully with all the history of these projects. However I note that these guys didn't have to BUILD THEIR OWN Logic State Analyzers. So maybe I can contribute something to all this?
What would be helpful to the community if painful for the developers is a public bug list so that if/when designs are After all, that's what they did at hp R and D... Have a nice day. Don Wallace

Re: Anyone want a rambox (made) for the hp 41? - Christoph Klug - 10-04-2005 Dear Don, if you create a rebuild version of the ERAMCO RAM-Box than realise the 128KByte version which includes 4 softwareselected banks...

You have seen Lyne Wilkins MLDL project/schematics?

Re: Anyone want a rambox (made) for the hp 41? - Meindert Kuipers - 10-05-2005 This is indeed the best starting point, and some other articles in the PPC, explaining the operation of the HP41 interface.
