Z80 emulator beta for Mac OS/X

[sje]

A few years ago I wrote a Z80 emulator for Mac OS/X as an exercise to teach myself NextStep (Cocoa) programming. It has a front panel GUI and can save/restore memory to a file. It does not have any emulated peripherals.

The front panel looks something like the old IMSAI 8080 FP with several added features bus cycle/instruction cycle step select, an eight Hz slow step capability, A register LED display, and a hexadecimal display of all the primary registers. The emulation runs at about one tenth the clock rate of the host CPU. There is no documentation (yet) other than mouse-over tool-tips.

I'm looking for a couple of beta testers who are proficient in front panel operation and who have an Apple Macintosh running OS/X. If you're interested, send a PM or email and specify PPC or Intel host machine.
