WN-6502-WBC. (WBC - WorkBench Computer)
Designed as a single-board computer the WN-6502-WBC is an electrical design, control and programming computer. Inspired by home computers like the Apple II, many games consoles and the users of the 6502.org forums. Made using a simple design and cheap-ish, easy-to-use and easy to assemble; This computer is perfect for beginners to electronics and veterans alike.
The first usable release will be version 2.0. This will be the case as we started at version 1.0 rather than 0.0 as this is hardware, NOT software.

FAQ:

Why a 6502?
Because why not? It was good enough for the Apple I, Apple II, the NES console and many other home computers and consoles, it is a well documented processor, plus EEPROM programmers and sockets are really cheap now.

What programs(s) did you use to design the computer and daughter boards?
KiCad for Windows bundle. 6.0
WinCUPL

Is this really free and if so how?
I work on this project in my own time and release all files under an OSHW license. WolfNet Computing is a not for profit organisation run by me. All files needed to manufacture are there, so the only costs are for the PCB manucfacturer YOU choose to use. :D

Where can I find licensing information?
In the main folder in HTML and Markdown

How do I add components or circuits to it?
At the moment only the 65SIB and GPIO ports are available for easily adding anything to. However there is a prototyping board in the works, this will facilitate adding components to the computer. You could also always use the KiCad libraries provided and create your own expansion card.

What size is the board?
305mm x 190mm.

That's a bit big for a board! What does it feature?

• 6502 Processor.
• Built-in Reset feature.
• Programmable Instruction Decoder. (Use the dedicated ROM to program the instruction translation. E.g. invalid op-codes -> BRK)
• 65SIB port.
• RS-232 port. (For PC communication.)
• Mini USB-B slave port. (For PC communication where there is no RS-232 port on the host.)
• 22-pin GPIO connector.
• 20/24-pin ATX compatible power connector.
• 3 processor clock speeds available. (2, 4 & 8 MHz)
• Bank switched RAM. (16 banks.)
• Bank switched ROM. (16 banks, 1 shared.)
• Processor bus expansion slots. (To be used as a slot for add-on cards that are added straight to the board. NO CABLE! That includes you Sir Richard Branson. xD)

Reasons for design choices:

• Programmable Instruction Decoder allows the user to translate instructions to other instructions outside of the processor and under the users control.
• 65SIB port for interfacing with external componennts via SPI for example. This allows for expansion cards, plugin boards and other things similar to these.
• RS-232 port will allow the PC to control the computer via serial connection using the PC's keyboard, mouse and monitor.
• 22-pin GPIO connector for other interfaces and connections like I2C or MIDI.
• 20/24-pin ATX compatible power connector to ensure a safe power supply is used.
• Bank switched RAM will allow the user to have one bank of memory per program running.
• Bank switched ROM means 16 programs on one EEPROM! Who doesn't want this...
• Processor bus expansion slots. There is already a sound card available for one of these slots.
