/* linescroll RAM - it clears to 0x3bf on startup which is enough bytes for 240 lines if each rowscroll value was 8 bytes, but each row is 4,
so only half of this is used? or tx can do it too (unlikely, as orl2 writes 256 lines of data) maybe just bad mem check bounds on orleg2.
It reports pass even if it fails the first byte but if the first byte passes it attempts to test 0x10000 bytes, which is far too big so
what is the real size? */
