FM Towns Marty 2/4MB RAM expansion card reproduction

Some months ago the user 'parodius' kindly loaned me a couple of ultra-rare add-on cards for the FM Towns Marty console, a video game console released in 1993 by Fujitsu, exclusively for the Japanese market.

They were a RAM expansion and a SCSI cards :

Since these cards are extrely hard to find (they popped up on Yahoo Japan Auction very few times) I took the chance to reproduce them.I started from the RAM expansion which is a nice add-on since it allows you to play on Marty some games that require more than 2MB of RAM.While reproducing it I stayed as close as possible to the original board layout, here is a side-by-side :

 Here's the reproduction plugged into the rear expansion port of the Marty console :

 Successfully tested it with Super Street Fighter II :

Thanks again to 'parodius' for the loan.
