I was reading a recent post about desirable cards and I noticed the Saturn 128k card was one that a number of people want.
Perfect timing because I have just completed the design for a reboot of the Saturn 128k memory card and they are much cheaper than current offerings I've seen.
I'm offering bare pcbs with gold plated edge connectors for US$10 plus $3.50 postage.
A download link for the GED files needed to program the GAL will be provided those that purchase a board.
PM me for my PayPal details if you want to order.
The cost of the parts I estimate to be less than $10.
