hi all..

Well i got bored last night and today and had just got a box of
stuff from my lockup that i hadn't seen inside for a good 10 years,
and i found a master system 2... plugged it in, it still worked, so
then i thought it'd be great to be able to play this in a real arcade
machine, i was a big master system fan growing up...

So thats what i did, removed the unneccesary bits, added some other
bits, and 24 hours later i have a completely Jamma compatible master
system, video, sound, controls are all at the right levels for a
standard jamma cabinet, the master system itself needs no controllers
to be plugged in, nor any external power supply, its just like having
another arcade pcb on your shelf, except you can plug one of 400
cartridges into it to play :)
There is a volume pot for the amp, and a toggle switch for 50/60hz
mode tucked away on the side, this is probably the single best thing
you can do to your master system, games play at the proper speeds and
are a totally different experience!

Anyhow, i might make a few more (different consoles next time), and
sling them on ebay, it was a fun little project! any requests for
them? i'm thinking megadrive/snes next, but i do still have more
master systems heh.

enjoy..

I was considering doing a similar thing to an old Amiga A500 that I have with a few broken keys. The F1 and F2 keys would be the P1 and P2 start so I could play Datastorm :)

just look out for an arcadia system, some are already wired for jamma
(think the ones I have are electrocoin though) - wouldnt't take long to
put a floppy drive back on to boot the game.

Mike,

I actually have some arcadia boards that I picked up cheap without
knowing much about them. When I plug in a standard A500 board it just boots
to the kickstart screen and goes no further. From memory, I probed around
with scope for a while with no schematics, found loads of floating signals
between PALs before putting it to the back of the que very much put off by
the fact that I have no information and don't really understand how it is
supposed to work. One for a rainy day I suppose.

Cliff.

cant be arsed to read all the posts, but from memory (and personally
owning) there where jamma converters for

Sega Master and Mega systems, you brought time, sega went after
anyone who op'ed one
PC Engine
Dreamcast
PSX1 clever system, dips set the game and you actually brought
credits.
Amiga, used rom boards for the games, Arcadia system rings a bell
and NeoGeo

Probably loads more, but these are the ones that I have come across
