Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

26 * NOTES about DMA transfers:
27 *
28 * controller 1: channels 0-3, byte operations, ports 00-1F
29 * controller 2: channels 4-7, word operations, ports C0-DF
30 *
31 * - ALL registers are 8 bits only, regardless of transfer size
32 * - channel 4 is not used - cascades 1 into 2.
33 * - channels 0-3 are byte - addresses/counts are for physical bytes
34 * - channels 5-7 are word - addresses/counts are for physical words
35 * - transfers must not cross physical 64K (0-3) or 128K (5-7) boundaries
36 * - transfer count loaded to registers is 1 less than actual count
37 * - controller 2 offsets are all even (2x offsets for controller 1)
38 * - page registers for 5-7 don't use data bit 0, represent 128K pages
39 * - page registers for 0-3 use bit 0, represent 64K pages
40 *
41 * DMA transfers are limited to the lower 16MB of _physical_ memory.
42 * Note that addresses loaded into registers must be _physical_ addresses,
43 * not logical addresses (which may differ if paging is active).
44 *
45 * Address mapping for channels 0-3:
46 *
47 * A23 ... A16 A15 ... A8 A7 ... A0 (Physical addresses)
48 * | ... | | ... | | ... |
49 * | ... | | ... | | ... |
50 * | ... | | ... | | ... |
51 * P7 ... P0 A7 ... A0 A7 ... A0
52 * | Page | Addr MSB | Addr LSB | (DMA registers)
53 *
54 * Address mapping for channels 5-7:
55 *
56 * A23 ... A17 A16 A15 ... A9 A8 A7 ... A1 A0 (Physical addresses)
57 * | ... | \ \ ... \ \ \ ... \ \
58 * | ... | \ \ ... \ \ \ ... \ (not used)
59 * | ... | \ \ ... \ \ \ ... \
60 * P7 ... P1 (0) A7 A6 ... A0 A7 A6 ... A0
61 * | Page | Addr MSB | Addr LSB | (DMA registers)
62 *
63 * Again, channels 5-7 transfer _physical_ words (16 bits), so addresses
64 * and counts _must_ be word-aligned (the lowest address bit is _ignored_ at
65 * the hardware level, so odd-byte transfers aren't possible).
66 *
67 * Transfer count (_not # bytes_) is limited to 64K, represented as actual
68 * count - 1 : 64K => 0xFFFF, 1 => 0x0000. Thus, count is always 1 or more,
69 * and up to 128K bytes may be transferred on channels 5-7 in one operation.
