Note the switch for CD/VCD
It seems that this system can select teritory and video signal

Unfortunately, this unit does not work correctly. It powers on and the CD drive activates, but it does not seek the boot sector of a CD ROM.
Since this page went up, I've recieved several emails from people with experience with the unit or others like it.
When I worked for <cut> I had the pleasure (yeah right :) ) to develop for the Sega Saturn. Unfortunately the development system that you have a picture of was discontinued and not supported by Sega sometime in 1995. This happened mainly because the system rarely worked and had a lot of problems with the CD drive. The common supported development system consisted of a real Sega Saturn that was modified to have an interrupt cable attached. This would connect to the CartDev system (this was a memory expansion and debugging module that interrupted any operations on the Saturn console while you were debugging or running your software. The CartDev would also communicated via cartridge that plugged into the cartridge slot on the Saturn.. The cartridge was attached to a cable that ran to the CartDev. The Saturn was also connected to a VCD (Virtual CD) unit made by <cut> systems. It was pretty good I guess, but the major pain was that you had to create a CD image each time you wanted to play a new version of your game.. very annoying as this sometimes took more than 15 minutes. The <cut> connected to the Saturn directly to a VCD control port on the side. you could toggle between the VCD and the regular CD tray on the top (in case you wanted to play your pressed game to test it on the real thing). I found the Saturn Dev kit to be extremely annoying and wouldn't wish it on my worst enemy. :).. but it was kinda cool never the less. Hope this helps.. But back on the topic of the original SDS.. it was a royal piece of crap and I only had the pain of working with it in my first 2 months of employment with <cut> back in 1995. It never worked and we eventually went to the standard CartDev rig.. Oh.. and there were two versions of the CartDev.. CartDev Rev.A and CarDev Rev.B... I would really like to say a prayer now for the unfortunates that had to work with the Rev.A ohhhh.. what a piece of junk.. We use the old one for parts if I remeber correctly.. :)... Welp.. good luck.
There is a dip switch (or two) somewhere
that WILL make it boot from the CD.
Unfortunately I havent seen one of these
boxes since 1997 so I can't
remember where that is. Play with it,
remembering what you've changed so you
can put it back afterwards.
Contrary to what the other guy (whoever
he is) said, I always found these
things to be pretty reliable. This, and
the second kit he talks about, were
very easy to use, and as a matter of fact,
were almost identical to the
official PSX dev system in operation.
