My latest tests with CyberMaster show that the maximum usable memory for downloading a program is 412 bytes.
The tests were made with Dave Baum's NQCC and I don't know of those how much are real program, since I don't know the structure of an .RCX file (which is the one downloaded). Anyway, 412 is a strange number for a limit...
This 412 byte limit in memory suggests that the total memory for CyberMaster is 1K. I don't know if the firmware also shares this 1K of memory since the RCX only have 512 bytes of SRAM for it, but I guess it must be possible.
If a task doesn't fit in memory, CyberMaster simply discards it. So if you have a program with 3 tasks and it finds out the last one will not fit, it discards it leaving the other two. The same I suppose should happen with the RCX.
As a bonus, here's a snippet for CyberMaster owners:
Hold down 'H', 'C' and the left mouse button when exiting the CyberMaster software and you'll see the whole team that created it! :-)

| (...) I thought we had determined that CM used a different processor model with 512 bytes more memory than the one on the RCX? stephen (confused) (26 years ago, 2-Dec-98, to lugnet.robotics)

| I've been playing around with programming the CyberMaster unit with NQC. I've noted that when the size of the program gets too large, the execution of the program fails in some way. The way it fails is sometimes somewhat inconsistent. I don't know (...) (26 years ago, 28-Nov-98, to lugnet.robotics)
