Yep, that helped a lot; slower, but who cared? My memory is fading now,
but I recall that the Z-80 had a "refresh" pin to tell any attached
dynamic RAM to refresh itself. The Z-80 was my favourite chip :-)

I toyed with the idea of Minix or LSX, but it would have to be stripped
back and I didn't think that the Z-80 was up to it, even though I had the
128KB bank-switched model. With the Hi-Tech C compiler I did get a number
of simple Unix programs to run, and even found a copy of CP/M UUCP (which
was overlaid to to hell and back).
I did have a copy of Concurrent CP/M, but never tried it.
