RE: HP-41 RAMBox Questions
Thanks Raymond, this explains a lot!
As for "ES RSU- 1A", yeah, I guess the "ES" was there all along as a hint, and I now see it's also in the QRG (it's always easy to see these things after one knows the answer...). Since my device is presumably a RAMBOX 32, which image should be restored: -RAMBOX 1B, or another, intact version of RAMBOX 64b? The extra commands in the latter presumably might be handy (excluding bank mgmt. Fns) As I understand this, Jurgen's new tool will not work, as that is tailored to the dual 32K banks in a 41CY (or presumably also a RAMBOX II). Is your init ROM for 32K units available? Possibly naive new question: If your init ROM is not available, can my image be repaired by un-protecting Page-8 of my module, and using HEPAX or ZenROM plus an image of the appropriate new RAMBox image in a CLONIX module page, copying that image to Page-8, thus overwriting the present modified/corrupted image? Thanks again Raymond! Though Raymond's comments resolve most of my questions, I'd still appreciate replies on questions 5 & 7 if anyone else has info. to share. --Bob Prosperi |
