C64 Tape Emulator based using an Atmega328p based on the design and firmware by Sweetlilmre (https://github.com/sweetlilmre/tapuino). Put your TAP-files on an SD-Card and plug the device in your good old Commodore.
Simple Z80 test design - single board with all the basics and a few luxuries.
**NOTE EasyEDA shows the most recent WIP for this project, which might be part way through me making changes. Before using the PCB layout please do get in touch (comment or message) so I can let you know if what you're seeing is stable! I create labelled versions of the project, but EasyEDA doesn't allow me to publish a...
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...
This is an attempt to create your own version of the calculator on the ATMEGA8 chip.
The purpose of the conclusions of the microcontroller is seen in the circuit.
The handling of 20 keys is described on my blog - http://un7fgo.gengen.ru/?p=2127 (I apologize, only in Russian).
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.
