This is a kit of emulators primarily focussed on the RC2014 environment and some of the Retrobrew (formerly N8VEM) systems. The emulators are focussed on software development and testing rather than cycle accurate simulation. They are designed to be easy to hack on when working on a problem, and simple to understand.
Device emulation varies in detail depending upon need. The device models should be easy to extend as required and currently reflect the focus on RC2014 and Fuzix.

ROM images, designs and board stocks etc and all to be found at https://retrobrewcomputers.org along with a forum. Most systems use the ROMWBW (see RC2014).
This site also hosts many of the other designs like the Tiny68K.

The classic "small board" design that was built to sit on top of a floppy disk drive. The emulator can also model the /PLUS version with NCR5380 SCSI. ROM images are not clearly redistributable so not included.
The ROM images for these machines are not redistributable, you will need an actual system to hand. nc100em has a small free ROM image if you just want to run ZCN, and it may work for Fuzix too.
Grant's website http://searle.wales/ contains full instructions on the design and building of this system. Also available are the needed BIOS, monitor and disk images. If you follow this design I strongly recommend you build it entirely using the equivalent CMOS parts (74HCTxx) and CMOS Zilog devices, as this makes the CF much more reliable and you can run far faster.
There are also designs for a lot of other systems that are not emulated.
A Z180 based machine with high resolution graphics. The graphics side is not currently emulated. Runs ROMWBW.
This lives at retrobrewcomputers.org. The ROM images are available as HEX files. To generate the rom do
makebin 10-HEXFILES/SMON35.HEX > sbc2g.rom
Available from http://stack180.com/. ROM images are available on the site.
A PCB based design closely related to Grant Searle's. Some discussion on the retro-comp group. This platform can use the Grant Searle ROM and CF images. Fuzix runs directly from ROM.

A retrocomputing project from the 2017 retro challenge
https://github.com/trcwm/HD6309-Computer
Emulates the VZ200 or VZ300 systems. Can also emulate the SD card add on and the Australian banked video memory extension.
https://hackaday.io/project/159973-z80-mbc2-a-4-ics-homebrew-z80-computer
including the files needed for the emulator. Note that the emulator emulates the Atmega API so no Atmega firmware is used or needed.
This kit is available from http://www.sunrise-ev.com/z80.htm. The emulation is of the full build, and does not emulate the LED display or keypad.
All needed emulation material is available from the site as well.
A fairly standard Z80 retro build with Zilog peripherals and 4 x 16K memory banking.
