While talking about separating the battery pack from the RCX it occurred to
me that having the thing forget all the firmware whenever you change the
batteries is a *pain*.
Making the RCX retain this in a semi-permanent or permanent fashion would be
nice.
Is it now possible to obtain a 9 Volt version of those small 0.5 or 1 Farad
capacitors that would be small enough to fit in the RCX rev 2.0 ? If you
replaced 1 battery at a time or did not leave them all out too long
something like this would suffice to keep the memory alive.
Would flash memory (like that of the SSFDC cards) be fast enough to execute
from ? You can get 16 Meg now for $50. The 2 Meg size should be cheaper than
a 2X4 standard brick. :-)
I think I will go look up the cycle times and such on the web. This would be
way cool to have an RCX with pluggable (and expandable) memory cards...

| (...) I have been able to change batteries without losing firmware or programs. Just line the new batteries up in the correct orientation, flip all the old ones out (it helps to have the +ve end such that your thumb goes to the larger gap there) and (...)
