RE: 71B MultiMod: MEMORY LOST when changing batteries?
Adding to Sylvain's comments... (and this applies to real devices, emulators can be more flexible)
You cannot merge multiple physical modules into a single IRAM. In fact a 64, 96 or 128KB RAM module, while able to merge into the single 'system RAM' space, are constrained to be 32KB IRAMs. For example, if you install a 64KB RAM module into port-1, it must be 'freed' in 32K ports chunks, as in: FREE PORT(1.00) - Note: FREE PORT(1) and FREE PORT(1.0) are equivalent FREE PORT(1.01) yielding 2 x 32KB IRAM ports. As for 'what retains the RAM?' it seems to be inherent capacitance in the overall system, which is likely why it varies from device to device and with differing modules installed. No doubt some of the h/w pukes will comment on options to install caps, etc. but as far as I can tell, it's just inconsistent magic. I'd risk a Neo, but not a 71B... --Bob Prosperi |
