/* Sega System E */
/*
Sega System 'E' is a piece of hardware used for a couple of Arcade Games
produced by Sega in the mid 80's. It's roughly based on their Sega Master System
home console unit, using the same '315-5124' VDP (actually in this case 2 of
them)
An interesting feature of the system is that the CPU is contained on the ROM
board, the MAIN System E board contains the Graphics processor, this opens the
possibility for using processors other than the Standard Z80 to run the main
game code on; several games have an encrypted Z80 module instead. However, the
system as a whole is very Z80-centric; using a completely non-Z80 processor
would require the addition of glue logic to the rom board to make the cpu
'look' like a Z80 to the rest of the system.
Also interesting is each VDP has double the Video RAM found on the SMS console
this is banked through Port Writes, the System also allows for the Video RAM
to be written directly, bypassing the usual procedure of writing to it via the
'315-5124' data port, it can not however be read directly, the same area used
for writing is used to access banked ROMs when reading
Pretty much everything on this hardware is done through port accesses, the
main memory map consists of simply ROM, BANKED ROM / BANKED RAM, RAM

Sega System E Hardware Overview
Sega, 1985-1988
This PCB is essentially a Sega Master System home console unit, but using
two '315-5124' VDPs and extra RAM.
The CPU is located on a plug-in board that also holds all of the EPROMs.
The games that run on this hardware include....
Hang-On Jr. 1985
Transformer/Astro Flash 1986
Riddle of Pythagoras 1986
Opa Opa 1987
Fantasy Zone 2 1988
Tetris 1988

Notes:
IC1: Z80 clock - 5.3693MHz [10.7386/2]
On some games this is replaced with a NEC MC-8123 Encrypted CPU Module.
The clock speed is the same. The MC-8123 contains a Z80 core, plus a RAM chip
and battery. When the battery dies, the program can no longer be decrypted
and the PCB does not boot up at all. The battery can not be changed because the
MC-8123 is sealed, so there is no way to access it.
IC2 - IC5: 27C256 EPROM (DIP28)
IC6: 74LS139
IC7: 27C256 EPROM (DIP28)
PAD1-4: These are jumper pads used to configure the ROM board for use with the
Z80 or with the MC8123 CPU.
PAD1 - Ties Z80 pin 24 (WAIT) to pin1 of the EPROMs at IC2, 3, 4 & 5
PAD2 - Ties CN2 pin B21 to pin1 of the EPROMs at IC2, 3, 4 & 5
PAD3 - Ties CN2 pin B21 to pin 2 of the 74LS139 @ IC6
PAD4 - Ties Z80 pin 24 (WAIT) to pin 2 of the 74LS139 @ IC6
The pads are configured like this..... (U=Upper, L=Lower)

When using a regular Z80B (and thus, unencrypted code):
PAD1 - Open
PAD2 - Open
PAD3 - Shorted
PAD4 - Open
When using an encrypted CPU module (MC-8123):
PAD1 - Open
PAD2 - Shorted
PAD3 - Open
PAD4 - Open
Additionally, a wire must be tied from CN2 pin B22 to the side
of PAD3 nearest IC6 (i.e. PAD3U).

A System E PCB can run all of the games simply by swapping the EPROMs plus CPU.
Well, in theory anyway. To run the not-encrypted games, just swap EPROMs and they will work.
To run the encrypted games, use a double sized EPROM in IC7 (i.e. a 27C512)
and program the decrypted opcodes to the lower half and the decrypted data to the upper half,
then connect the highest address pin of the EPROM (A15 pin 1) to the M1 pin on the Z80.
This method has been tested and does not actually work. An update on this may follow....

Game Notes:
Riddle of Pythagoras is interesting, it looks like Sega might have planned it
as a two player game, there is prelimiary code for 2 player support which
never gets executed, see code around 0x0E95. Theres also quite a bit of
pointless code here and there. Some Interesting Memory Locations
C000 : level - value (00-0x32)
C001 : level - display (00-0x50, BCD coded)
C003 : credits (00-0x99, BCD coded)
C005 : DSWA put here (coinage, left and right nibbles for left and right slot
- freeplay when 0x0f or 0xf0)
C006 : DSWB put here
bits 0 and 1 : lives ("02", "03", "04", "98")
bit 3 : difficulty
bits 5 and 6 : bonus lives ("50K, 100K, 200K, 500K", "100K, 200K, 500K", "100K,
200K, 500K, 99999999", "none")
C009 : lives (for player 1)
C00A : lives (for player 2)
C00B : bonus lives counter
E20B-E20E : score (00000000-0x99999999, BCD coded)
E215-E218 : hi-score (00000000-0x99999999, BCD coded)
E543 : bit 0 : ON = player 1 one still has lives
bit 1 : ON = player 2 one still has lives
bit 2 : ON = player 1 is the current player - OFF = player 2 is the
current player
