RomWBW on the NABU Personal Computer

With my NABU RomWBW Option Card you can turn your NABU into a complete standalone computer running the RomWBW BIOS. Boot a variety of CP/M operating systems from compact flash or directly from ROM. No floppies and no Cloud CP/M.

The Option Card pulls -12,+12,+5,GND and 3.58MHZ from the Option Card slot pins and all other signals are brought over from the 40 PIN ribbon cable that plugs in the Z80 slot. No modifications are required (you can even leave the original NABU ROM in the motherboard if you wish). There's a 16550 UART on the card running at 115,200 baud along with an IDE port (82C55 based). The IDE port can boot directly from compact flash.
