Intellivision: update comments and fix rom locations on intv1
hardware. Note the intv1 exec.bin still needs to be split to
the two separate roms that the real hardware used. [Lord Nightmare]

2727<kevtris> that's about it
2828<kevtris> the samples are stored in the game ROMs, and are easy to extract

30RO-3-9503 = 2k self decoding address mask rom without external address decoder & bus
31RO-3-9504 = 2k self decoding address mask rom with external address decoder & bus
32RO-3-9505 = 8k self decoding address mask rom without external address decoder & bus
33RO-3-9506 = 8k self decoding address mask rom with external address decoder & bus
309502, 9503 and 9504 are the chips used in the intv1 (the sears one may use different chips)
319505 is used in some carts
329503 and 9506 are the chips used in the intv2

34Known roms so far:
35RO-3-9502-011 = 4KiB(2Kiw) self-decoding mask rom with decoder & bus, (DIP40 containing 1/2 of EXEC, maps at words 0000-0fff or 1000-1fff [unclear which, guess is 0000], i/o maps at ?), located at U5 on intv1
36RO-3-9503-003 = 2KiB(1Kiw) self-decoding mask rom with decoder & bus, (DIP40 containing GROM, maps at words 0x3000-0x37FF, i/o maps at ?), located at U21 in intv1, U5 in intv2
37RO-3-9504-021 = 4KiB(2Kiw) self-decoding mask rom without decoder or bus, (DIP28 containing 1/2 of EXEC, maps at words 0000-0fff or 1000-1fff [unclear which, guess is 1000]), located at U6 in intv1
38RO-3-9506-010 = 8KiB(4Kiw)+512B(256W) self-decoding mask rom with decoder & bus, (DIP40 containing EXEC2, maps at words 0000-1fff and 0400-04FF, i/o maps at ?) located at U6 in intv2

40rom types (suspected, not proven yet):
41RO-3-9502 = 4KiB (2Kiw) self decoding address mask rom with external address decoder & bus (DIP40)
42RO-3-9503 = 2KiB (1Kiw) self decoding address mask rom with external address decoder & bus (DIP40)
43RO-3-9504 = 4KiB (2Kiw) self decoding address mask rom without external address decoder or bus (DIP28)
44RO-3-9505 = 8KiB (4Kiw) self decoding address mask rom without external address decoder or bus (DIP28)
45RO-3-9506 = 8KiB (4Kiw) self decoding address mask rom with external address decoder & bus (DIP40)
