# Emulator Kit



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.

# Hardware And ROM Images



## RC2014



### Community



Google Groups: rc2014-z80. Note that the list owner's policy is that this

list should be for discussing Z80 based RC2014 systems only.



Google Groups: retro-comp. RC2014 and BP80 based systems and other stuff.

Created as a place to discuss things not suitable for rc2014-z80.

### CP/M Disk Images (for non ROMWBW systems)



https://github.com/RC2014Z80/RC2014/tree/master/CPM



## Retrobrew (formerly N8VEM)



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.



## 2063



A Z80 based system with bitbang SD card and 32K memory banking.

## Ampro Littleboard



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.



## Amstrad NC series



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 Searle SBC



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.



## Rhyophyre



A Z180 based machine with high resolution graphics. The graphics side is not

currently emulated. Runs ROMWBW.



## SBC2G



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



## SmallZ80



Available from http://stack180.com/. ROM images are available on the site.



## Tom's SBC



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.

## TRCWM6309



A retrocomputing project from the 2017 retro challenge



https://github.com/trcwm/HD6309-Computer



## VZ300



Emulates the VZ200 or VZ300 systems. Can also emulate the SD card add on and

the Australian banked video memory extension.



## Z80 MBC2



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.



## Z80 Membership Card



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.



## Z80 Retro



A fairly standard Z80 retro build with Zilog peripherals and 4 x 16K memory

banking.
