    • Sega System 18 multi kit installation & support

      Yes we finally got to this point!

      Please note this thread isn't an interest thread.

      And as always:
      Please remember all kits come with blank EPROMs/flashes. Games are NOT included.

      S18 multi installation is similar to S16B, even easier: it's a complete replacement romboard that requires no soldering nor jumper setting, and can't be plugged backwards due to connectors size and spacing.

      Specifications:

      - Based on 3.0V flashes for storage with proper power regulator and level shifters
      - 16 available banks selectable via rotary selector (no dipswitches here)
      - Still has header pins for a remote selector plus 4 additional pins for power and reset line for neat selector solutions to be plugged ( @Frank_fjs)
      - Custom chip used for the bigger games reproduced in a CPLD

      Selector positions:

      GamePosition
      Alien Storm0
      Bloxeed1
      Clutch Hitter8
      D.D. Crew9
      Desert BreakerA
      Hammer AwayB
      Laser GhostC
      Moonwalker2
      Pontoon3
      Shadow Dancer4

      That's all for today!
      Looking for:
      - faulty Hang-On, Space Harrier or Enduro Racer (2203 sound board)
      - Sega Mega-CD 1 power board
      - Super Nintendo CPU (3 needed)

    • You know the way to my heart. <3

      What's the story behind Pontoon? Was it actually a dedicated S18 hardware release or something you've managed to port across? Sorry for the silly question, just not a game I've ever heard of.

      Re the OLED selector - Apocalypse and I have collaborated to ensure a smooth product. I've already designed the hardware and code, just awaiting some pixel artwork. It will literally be plug n play, no soldering or wiring required at all. Thank Apocalypse for this as he had the foresight to accommodate external games selection devices from the get go.

      I'm excited! I love Sega hardware. Having S16 covered is awesome, bringing S18 to the table is super awesome!

      It's a card game where the S18 motherboard is probably plugged to an external device (similar to Caribbean Boule on X board hardware?).
      Depending of the data received it displays a different animation (shuffling cards, drawing, etc.).
      It's included in case someone has the proper cabinet but not the game board.

    • @Apocalypse can you talk about the CPU requirements a little?
      I'm assuming it needs a normal/standard/replaced 68K just like the (ver1) System16 multi (and conversions).

      How about a projected price for the board?
      Again assuming something similar to System16 but perhaps the new storage has added to the cost.

      Correct, a standard DIP64 68000 CPU rated 10MHz min.

      Yes we target $250 with blank flashes. Funny enough a solution with less chips for storage (5) is actually more costly than a solution with 19 good ol' 27C322s... Plus the CPLD, level shifters, regulator, rotary selector vs dipswitches but only for the better!

      Very cool! :thumbup:

      Thanks for the information and your amazing work on this multi.
      Sega arcade hardware has been ignored for far too long IMO.
