Olimex Neo6502pc is a retro PC that combines an Apple II compatible chip with a RP2040 microprocessor

The Olimex Neo6502pc is a modern mini computer designed to run some very old software. At its heart is a single-board computer that features a 6.25 MHz W65C02 processor that’s similar to the 6502 chip used in classic PCs and game consoles like the Atari 2600 and Apple II, which makes it possible to run emulators for those devices on this […]

Three #W65C02 to 6502 adapters. The top two use buffers on control and data lines (one uses ACT, the other HCT).
The last one, the newer, uses nothing and just adapts the pinout and adds a pullup.
Should have some time to test them on a real #VIC20 relatively soon.

Given the positive experience with the 386 #adapter, why not leverage the same process for something slightly different?

TheByteAttic designed a #W65C02 -> 6502 adapter that buffers the data bus with an 'HCT245, this is a variant of the same design (with another '245 for inbound control lines too), but, instead of having the transceivers on the side, it uses #SMD pins to occupy the exact same space as an original 6502, allowing a #QFP CPU to sit on top of the adapter.

I'd like to use for repairs on #VIC20 units.

So I can do the Shatner. All day long.

Over and over.

The Neo6502 Is A Credit-Card Sized Retro Computer

The venerable MOS Technology 6502 turned up in all kinds of computers and other digital equipment over the years. Typically, it was clocked fairly slow and had limited resources, but that was just …

Neo6502 the credit card size Open Source Modern Retro computer with W65C02 processor prototypes are ready for test!

Finally we managed to build few prototypes for tests! The delay was caused by components supply problems for the new components in these boards which we do not stock. Anyway the new shiny purple co…

There will be a #MOS6502 compatible version of the #agon single board computer! Based on the WDC #w65c02 cpu, with assembler and disassembler in ROM. Hopefully someone will adapt #BBCBASIC for it:
