The 64KZ is organized as two 32K Blocks (not 16); the A15
switches control whether that block is in the lower or upper
half of the 64K range.
Reset out disables that block after a reset to allow the boot
ROM to use that space on power up.
Override & DMA are only relevant for DMA operations.
Bank switching is done by outputting a byte to 40H
(this address is set by a jumper block/PROM):
bit 0 = bank 0, etc., and each block's bank(s) are of
course set with SW2 & SW3.
Good luck; I've got a manual somewhere that I could scan
if you haven't already gotten one elsewhere, but probably
not this weekend. Email me off-list if I can help.

Subject: Cromemco 64KZ Info Needed
Reply-To: cctalk(a)classiccmp.org
Hope this is not a duplicate. The first one did not show up.
I have just obtained a Cromemco 64KZ board. This has 64K of RAM and
I'd like to test this out this weekend. Unfortunately, I don't have
any documentation.
There are 4 banks of RAM (16K x 8) Each bank is labeled "page0",
"page1", "page2" and "page3". There are also 3 8-pin dip
switches:
I have a couple of photos at:
http://www.msdsite.com/vcomp/cromemco/photos.html
Since this is a 64K board and since there is other memory in my
system. I'm hoping this allows some sort of bank switching. But
without docs, I don't know how to use it.
I assume the Bank A/B allow setting which bank a particular 16K might
reside but am not sure. And the address lines of A15, A14 are a
mystery.
Is there a way to switch banks by writing to an I/O port? Location?
Can any of you help with an explanation how this works and how I might
use the switches?
Thanks in advance,
Mike

Any chance you have a copy of Cromemco's Macro Assembler for Z80 user

I thought Trek-80 only ran on the VDP boards. Or did they have a version
for terminals? (I mostly played it on the SOL-20).

The system that I have, currently has 32K RAM and uses the Soroc
serial B/W terminal. Anyone have a good classic basic game (that's
short) and I'll enter it and see what it looks like on this old
terminal :-)

Starlanes is a graphics-done-with-text empire trading game. The details
are a little hazy, but it's basically a 2 to 4 player game. Each player
takes a turn. You buy stock in a company, and when you have enough stock,
you can create an outpost. You can add to exist outposts, and if two
outposts collide (because of a limited playing area, 16 rows by 30 chars,
maybe?), they merge. I think which ever is larger wins the merge, and your
stock is adjust accordingly. While not a complicate game by any means,
there are some various strategies to play. I'm pretty hazy on the details,
since it's been at least 15 years since I played the last game. I've always
wanted to find a PC copy (but never made much of an effort).

About 10 seconds with google found this:

Of course, I have no idea how close it is to the version you remember.

I've managed to make a copy of my bootable disk and now want to copy
files from A to B.
I have a program on my CP/M disk that's named CopyAToB.com. I assume
it does what it suggests but I don't know what the proper command
usage is.
I executed copyatob with various guesses and always get, "SELECT
ERROR DISK N"
Anyone know how to use this program? I can't find anything on this
on the system.
Is there an easier way to copy programs (files) from one drive to
another using CP/M? I'm a bit rusty on this:-)

No, I figured out the pip.com I guess.
pip B=filename = a=filename, unless there is something else I should
know other than that.

The "normal" way in CP/M is PIP. D'ya need info on using it?

well,...
colons!
For people coming from the PC-DOS world, it takes a little getting
used to "target" = "source", instead of "source"
"target"
And there were a few command line options that might be useful (such as
going all of the way to the end of a binary file, rather than stopping
when hitting what appeared to bean EOF character.)

Sorry, typo.
I'm using version 1.3 and my documentation is for v2.2 so it's a
little off.
In 2.2 one can copy all files from a: to b: with:
pip b:=a:*.*[v]
but in 1.3 I get an error. anyone know if full disk of files can be
copied or must I do it one file at a time?

By short, I meant something I can do in enter in a few hours. I'd
say short is 3 or 4 pages. :-)
I'll look for starlanes.
