Z80 to 8080 code convetor?

[BrianS]

If the driver makes use of the "fancier" Z80 interrupt modes- this will be hard. Also remember that the Z80 has the second set of general purpose registers that were often used for interrupts. You can do a lot with the Z80 more efficiently than the 8080.

At least one converter does exist -- part of a matched pair of 8080 -> Z80 and Z80 -> 8080 converters for CP/M. Search for XIZI-3.LBR on (eg) the Walnut Creek CP/M CDROM.

So what "vintage" controller works best with an 8080?

I have an FDC+ on my Altair currently, I assume that uses DMA?

The program "XIZI" that John cited doesn't do what you think it might--it merely translates Z80 assembly to equivalent 8080 using 8080 names and syntax. It does not translate Z80-specific instructions, nor instructions that use Z80-specific registers, but it will flag them.

That could still be somewhat helpful.
