BigBoard 2- Z80 CP/M 2.2 System

[james.h...@gmail.com]

I built a BigBoard 2 way back in 1982 from a bare board. I still have that system, and it still runs! I would like to add a "hard drive" to it. A CF card would be ideal so I guess I need to turn my SASI interface into an IDE interface. Is there any info available or better yet at kit?
Any Info would be greatly appreciated.

Since you've already got a SASI interface, a BlueSCSI board might be
simpler. I've built one and plugged it into the SCSI port on my Ampro
LB/Z80 and it works like a charm.

Take a look at this solution:

How about adding 4 Gotek (or clone) drives? Apparently, you can define a drive type of up to 255 tracks, some number of sectors, another number of bytes/sec. Adding some static ram beside the ROM will suffice for sector buffers in my mind. Of course, that will mean hacking the BIOS...
