The unit is a bit touchy about power.? I couldn't run it of the USB hub under my monitor, because the voltage under load was too low (4.70).? Plugged directly into the computer, it works fine.

Just got the confirmation email, did order the usb cable and ftdi adapter. Didn't remember that, but did know I left a yes anywhere it would take one. They're quote 3-5 weeks shipping time. I'm gonna need to stay busy. ;)? I may just have to order a powered USB hub. I've wanted one for several years, this could be a good excuse.?

I'm hoping there will be a way to put video on it, one of these days. I'm pretty much starting from scratch, as far as legacy computers go. May have to rob the chips from this one to go on a different board. Been a long time since I did any electronics. I may have to go back to school for that, too.?

This is a pretty interesting little micro. I'm interested to hear how it
turns out! But it's off-topic for this thread, as it doesn't have video
at all. You may want to continue discussions on a new thread?

64180 was availabe in that large pin dense dense dip or flatpack [J lead TQFP]
as is the Z180 and they are both about the same.? I have both and save for
clock speed same thing.? ITs biggest features are built in dual uart (dart similar),
a bit serial somewhat like I2C, timers and DMAC.? There are screamingly fast
versions to be found, I have a handful at 10mhz and one that is spec'ed for 20.
I also have SB180 that used the 64pin dip with the SCSI interface and the?
BCC180 (at 18.432mhz) using the TQFP as well as a few HB designs.
What makes the Z180/64180 less popular is programming the MMU is a
real pain.? The result of any programming is still only 64k addressable
space scattered in the 512K (64pin) or 1MB (TQFP) space.? That and
not everyone likes the onboard peripherals.
There is the much harder to find Z280, takes a z180 and adds 16bit wide (startup
configurable) bus for speed and extended but upward compatible instruction set
with indirect addressing modes and 24bit addressing via I&D spaces plus a real
MMU.? That part makes it easy to have 8mb ram and 8mb rom.? You need mask
level parts higher than H for fewest bugs.? Performance for the Jrev at 12mhz?
can beat a 8086 up to 16mhz.
However for just plain fun the base Z80 at 4-10mhz is a good pick for simple
systems.

There was the P112 and its follow on.? IT was popular but the date was 1980 and 8088 was?
showing its face finally (it had ben around for a while but no takers).
.
FYI 64180 and Z180 are to most still a z80 and programs at the application level (CP/M) the same.
What the big deal Z180/64180 were z80s aka 8bitters..? 8088 and z8000,and 68000 were
bigger word size and minimally 16bit.? ?When everyone decided 16 it was it, the market
shifted fast and by the summer of 81 (just pre PC) it was already a 16 bit world.? Not to
say 8bitter were not in use but they were already hitting the memory wall.
TWhe sallwarts went to Z180/64180 as it was faster, offered the potential for
larger memory space (512k) and CP/M3, Zrdos and a few other cp/m compatables
could support that space.? The apps were still Z80 but way faster.??
8088 was nearly as easy to build up as the 8085.? Totally program (binary) incompatable.
But it was a thing.

Hi, Bill,
?
Perhaps your “pocket-sized Z180 computer” has arrived by now.? If so,
you may be looking for something to run on it.? So here’s a quick
“something to send your way”:
?
This is a reasonably complete implementation of the Adventure (“Colossal
Cave”) text-based game.? I whiled away many hours as an undergrad playing
it.? (I was using a TI Silent-700 printing terminal, and just fed the
out-feed paper out the open window; eventually, it reached the ground from our
9th floor room...)? Once you figure out how to create a working disk image
to play in, and download things onto the “disk”, you can download the game
itself.? I downloaded the following files:
?
?? USQ.COM, ADVENTUR.MQG, and ADVENTUR.COM
?
then used the USQ utility to decompress the messages file , but I also
included the decompressed file; also the source, and such documentation as
exists (remember that .DOC files under CP/M are simple text files, not Word
documents).? There are also some maps, and sources for other
versions.
?
I have a bunch of other stuff, too.? If you’re interested in program
development, I have Turbo Pascal (which I actually used professionally), and a
really neat compiled Basic written by Jack Ganssle (embedded systems guru for a
few decades now).? Also, the original WordStar 3.0 installation set – I
used WordStar as my primary editor for several years, both for programming and
actual word processing, on fairly large projects.? Let me know if you want
any of these.
?
Cheers!

I've copied everything I could find on the
internet, but I'll happily take anything you want to send my way, too. I do have
a question for you on hardware, though. Can you recommend an ftdi card or cards
so I can talk to the thing when it gets here.? I've got these sitting in my
amazon cart, with some 4" jumper leads for hookup, but not sure this is the best
option. Also don't know if I'll need two, or if just one will do.
?
The Tindie site warns of possible long delays
in shipping due to Covid-19, so no telling how long it will take for the
hardware kit to get here. I got a book I bought from the UK in less than a week,
but they seem to think it could be months, too.

Bill, I saved almost all of my CP/M stuff in files in my master "everything
I've ever done" hard drive archive, so if there's anything you need (WordStar in
file form, rather than disks), let me know.
I found
a copy of Adventure (Colossal Cave) for CP/M, and copied that all into User
space 1.? That's always good for a ten-minute break, too...
