Check the listing for details. MiniMax8085 Intel 8085 Single Board Computer - PCB + Kit of Parts. Listed at 75.00 USD. This listing is for a kit of parts and PCB that allows you to build the popular 8085 based single based computer as designed and published by Sergey Kiselev on GitHub: https://github.com/skiselev/minimax8085 I was building a unit for myself and ended up with a lot of spare parts, so sharing full kits here. I modified the PCB slightly from the original (but changes are minor - for example slotted holes for the power socket, and provided a connector for USB-to-TTL converter). Please note, this kit is configured to use USB to TTL adapter (included in the kit). The adapter will conveniently provide both the serial link to your computer and the power required to run the SBC. See the BOM picture for full list of what is included. EPROM and GAL will come programmed. Passives components (like capacitors, diodes etc) are new, chips - some new old stock (unused) and some are used. Each set of components will be fully tested before shipping. One of the picture shows a completed unit for illustration only. This is a DIY kit of parts, you will need to solder all components. To operate the SBC after soldering you will also need a standard USB-mini to USB-A cable (not included in the kit). Thanks for looking.
