prints out the base addresses of the apple ii hi res screen

apple_ii_hires_lines.py

addrs = [0x2000, 0x2028, 0x2050]    # 3) 'top','middle','bottom' base addresses
for addr in addrs:
    for b in range(0, 8):           # 2) and those 8-line bars are striped each 0x80 bytes
        lineaddr = addr
        for l in range(0, 8):       # 1) 8 consecutive lines are spaced by 0x400 bytes
            print(hex(lineaddr))
            lineaddr = lineaddr + 0x400
        addr = addr + 0x80

this makes sense to me, I never saw it this simply before
