[memory] Emulate main memory read wrap-around

  • Fri, 18 Jan 2013 17:18:50 +0000

  • [memory] Emulate main memory read wrap-around

    3B1s with 512K or 1MB of base memory have a decoding quirk which causes reads
    to 'wrap around'. That is to say, on a 512K machine, reading from addresses 0,
    512K, 1024K or 1536K will address the same RAM byte. On a 1MB machine,
    addresses 0 and 1024K address the same RAM byte.

    Emulating this incorrectly causes P4TEST to report an incorrect amount of
    available base RAM.

fix default HDD sectors-per-track

  • fix default HDD sectors-per-track

    The 64MB Micropolis drive we're trying to emulate in FreeBee has 17 sectors
    per track. Fix this in main.c to avoid tripping the sector range checks.
