Hahaha, you're not kidding; there are a few Lisa Rambos out there.

Thinking he's talking about the LRambo mod as seen here.

Hi, as the colleague says, the LRambo card was a mod for a Sun Remarketing 2mb RAM card that supported the 4mb option for use only with the Mac system, not with Lisa OS.

This is a render of a 2MB SUN REMARKETING card. If you look in the center, there's a jumper to convert it to a 4MB card. A mod to the Lisa motherboard is necessary for it to work.

Good suggestion, but I probably won't add 4MB of RAM because of the extra cost of a second RAM chip. The boards are already rather pricey, and another chip just increases that price further. And plus, I think only a select few people would use 4MB to begin with. I'm guessing that most people who want an FPGA Lisa are probably going to be using it to run the unique LOS/Workshop/Xenix/UniPlus OSes as opposed to your generic Mac OS that can be run (and run better, no less) on any old Mac.
