41CL and available flash pages

YUPS is completely full, and it took me almost a week to find the bytes to add the CPONLY function. The problem is that any change will affect all board revisions, so V2 will skip 0x0F8-0x0FF, V3/V4 will skip 0x1F8-0x1FF and V5 will skip 0x3F8-0x3FF. I will try to implement it so that the "*" automatically excludes the top sector, but specifying it directly will still be allowed.

I use the top sector for backups and just do FLCHK? "000>3F7" to skip that sector, but that's just me.

It sounds like I need to look into creating a "41CL Backup Functions" to help manage the process of backups. I've been thinking about it for a while, but haven't found the time or motivation yet. The one complication is the "expanded memory" in pages 0x801-0x803 and deciding whether or not to include those in a backup.

My head hurts from all the wall-banging, but what I have right now is:

For V2 boards, "*" means 000-0FF (no sector skipped)
For V3/V4 boards, "*" means 000-1F7 (single top sector skipped)
For V5 boards, "*" means 000-3DF (top four sectors skipped)

My thinking was to reserve more space where more space was available.

Is this reasonable? Or should I just skip just the top sector all the time?
