As always, thanks for sharing!

I created a small benchmark to test the performance (computing Pi to 100 digits).

Pi100 takes 1.62 seconds with a 2 Mhz 8080.

1.51 seconds with a 2 MHz Z-80 SoftCard (same 8080 binary).

With Apple80 @ 1Mhz, 233 seconds (same 8080 binary with a modified echo). ~144x wall clock time. I originally wanted to do 1000, but it would have taken ~6.5 hours.

Native 6502 performance for 100 digits is 1.16 seconds.

Kudos for Dann's 1979 (a year before the SoftCard) achievement.

I had a discussion with him about his software in October after my purchase

Is he still taking bug reports?  :-)

I created a nicer .txt of the manual I can send to you.

Thanks again.
