Simple Z80 test design - single board with all the basics and a few luxuries. The board has many more options than it really needs so that I can experiment. All devices are through-hole to make the build easy for those of us yet to venture into SMD. Influences for this project include the RC2014 512K RAM/Flash card and the SIO/2 card along with bits and pieces from all over the Internet that I've...
This board combines the best features of currently available RC2014 memory boards in one:
- One 512K memory chip which can be RAM or ROM (selected with 3 jumpers)
- One 512K RAM chip
- Select between linear and paged memory using a single jumper
- Select between linear and paged memory in software (from Z80 or BusRaider)
- Support for the PAGE pin on the RC2014 bus (with an optional pull-up selec...
Modification board to provide CVBS (Composite) video output from the Colecovision
Surface Mount only Version
LM318 or LM310 Can be used in this circuit, there is a jumper on board to select which one you used.
# Wifi Modem ESP8266 - ESP-01 #
**for Retro Computer**
Simulates the old-style Hayes "AT" commands, so that the ESP8266 appears to the terminal as if it were a Hayes modem. These "AT" commands may then be issued to the ESP8266 in order to force it to connect to a wireless access point, and from there to make one or more manageable connections to the internet. It also includes...
Replacement for Atari Falcon Dallas 12887 RTC brick. Featuring pin header for battery (3V) and reset pins. Closing them for a short time while turning on the machine should reset the stored clock settings. Disconnecting the battery will probably do the same thing.
Based on the Arduitape by Duncan Edwards. Download his firmware from http://arduitape.blogspot.com/ and remember to support him and his work.
