RE: W&W 32K RAMBOX re-initialization ROM
Hi Jürgen, Peter,
The access to the ERAMCO RSU-2 128K Rambox is documented in this article from 2008... (Tempus fugit). Also there is an ERAMCO RSU-2 256K Rambox using 10x62256 RAM chips. I have not seen this documented anywhere, so it may be just a prototype. I have only seen one such unit, wich I repaired back in 2017. Coincitentally I have received it again for service and OS restore this very morning. The access to the 8x32K banks in this unit is also SW driven, but works in a very different way from its 128K counterpart. I haven't yet got my notes about the details, and certainly I can't remember the procedures from the top of my head after 7+ years. ![]() If the owner allows me, I'd gladly share what I found in case there is some interest on the subject. Best wishes from Spain. Diego. PS: @Jürgen, Finally, I managed to recover the 41CY I was working on last week. "Do not suppose, check it twice." |
