Up for auction is an untested PlayStation 1 programmer tool PC development board and internal PC CD-ROM drive.  Both items are untested and sold as is.  These came from a developer long since out of business.  Also including an installation and operations packet for the DTL-H2500.  I also just found a few unmarked possibly programmer tools CDs which I will include.  I'm not a programmer and don't know anything about the discs so they may not be useful.

This PC development board, DTL-H2500, is the third generation development board for the PlayStation.  It inserts into a PC (circa 1997) and allows you to code games.  The internal CD-ROM drive, DTL-H2510, is to be used in conjunction with the DTL-H2500 board so you can play prototype games.  The internal CD-ROM drive is also a second generation drive, with the first generation being an external drive.  

The development board has double the RAM of a standard PlayStation 1 in order for debugging purposes.  I don't have the cable that connects the CD-Rom drive to the board.

**My development items have been packed for years and some were held in storage by the International Center for the History of Electronic Games at the Strong National Museum of Play.  There is an unreleased prototype game inside the CD-ROM called Dream Team Basketball. You may keep the disc for testing purposes only or discard it in the trash.
