Still how do you transfer stuff from a floppy ( or

I have yet to see a CP/M system with no external I/O

doesn't sound very useful, so why would one care about transferring
stuff to it?

Who said the N8VEM SBC has no external devices?
I was replying to your question, quoted above. I never said anything
about an N8VEM SBC.

Eric,
Oh, I think I see what happened. The quote you attributed to me is actually
from Ben.
Everything I said is below the -----REPLY-----
I never asked that question and wondered why you asked it. Still, the
response is valid.
BTW, the N8VEM SBC is the actual name for the home brew Z80 SBC I built.
I am offering the PCB to others of similar interests.
Probably there has been enough discussion from me on the topic.
If anyone is interested please contact me offline or join us on the N8VEM
google group:

Thanks and have a nice day!

Well here is my real quote "Why does a EPROM burner seems the default
device everybody seems to have hiding in thier junk box".
I am still looking for one under $1K and not overseas.
Ben.
PS. I did have a EPROM burner on Z80 S100 mother board but
it got tossed years ago do to a flakey power supply and lack
of $$$ to upgrade to a real computer.

Because every hardware hacker should have one (along with an EPROM
emulator :D)

Beeprog from Elnec. You can't go wrong, and it is CHEAP.

Dave,
If you need any help with your PromICE, let me know. I worked with
the founder of Grammar Engine years ago, and I have used their
ROMulator and PromICEs extensively (we used to help them out back
when VMS support was relevant - they would bring their download
code over, and we'd compile it for them).
Theirs was the first EPROM emulator I worked with, and I have to
say the experience was fanstastic. Our first target was a VAXBI
COMBOARD - with EPROMs, we'd have to shut down the VAX and remove
the board *plus* all the usual edit-compile-burn time, then put
it all back and restart the VAX - about an hour cycle time to
fix a bug. With the PromICE, since we booted our target board
anyway as part of the normal use cycle (not common in embedded
boards, but ours used host-bus-downloaded application code, so
we soft-booted our boards *lots*), the makefile handled the
compile-download-boot phase by itself, and our turnaround time
was more like 5 minutes.
It made debugging go really, really smoothly, especially when we
were having problems with one particular sort of VAXBI cycle.
Cheers,
