Tapuino is a Commodore Datasette emulator for C16, C64, C128 and VIC-20 based on the design and firmware by Sweetlilmre. Put your TAP files on an SD-Card and plug the device in your good old Commodore.

This is a peripheral card for the Apple ][ series computers that acts as a read-only solid state disk drive (SSD) all in EPROM. Although it won’t run DOS, it is fully ProDOS compatible and will appear as a read-only hard drive even when booting from another drive. It holds 1024 KB of disk data making a full megabyte. The firmware for the card resides in block 0001 that is normally reserved for SOS boot on Apple ///. The drive boots ProDOS and into BASIC in under 1.5 seconds. This is the fourth and latest revision of the board with 4 more blocks than versions 1 through 2.5 and fixes a data buffer issue in versions 2.1, 2.5 and 3.0.

This is a project for a digital DVI/HDMI Apple II video card. It directly produces a digital video stream from Apple II’s memory content. The signal is output via an HDMI connector, connecting the Apple II to modern displays with HDMI (or DVI) inputs. No more analog signal conversion required. If using with an Apple IIgs it will only work when using native Apple II graphics modes.

The project is a collaboration with Thorsten Brehm. His related firmware project is here: https://github.com/ThorstenBr/A2DVI-Firmware

This is the ONLY the HDMI break out board for the A2DVI card. However, you can buy a pre-made from Digikey. Here->https://tinyurl.com/3hh769ey

You will also need the A2DVI HDMI break out board (https://oshpark.com/shared_projects/qDqVejj3) or you can buy a pre-made one from Digikey. Here->https://tinyurl.com/3hh769ey

Expansion card that adds an MC68882 FPU to your Macintosh Classic II. The board has two layers to keep the PCB cost down. It offers a switchable clock source between the system clock (16 MHz, synchronous operation) and a crystal oscillator on the board (20,32, or 40 MHz, asynchronous operation depending on your crystal and FPU chip. If you just want a stock 16MHz FPU, leave off the oscillator and use a MC68882FN16A chip). If you want to overclock, use a faster FPU chip such as a MC68882FN40A, and the appropriate oscillator. It has been shown that the FPU can be overclocked up to 40MHz, but based on experience, keeping it around 25-33MHz maintains better CPU performance.

I added a pad for an optional 1206 LED and a spot for a 200ohm resistor.
