Adapter for Atari/Sega joysticks on Apple II / Franklin ACE 1000.

This is a slight reworking of Tor Arne Hustvedt’s “Apple IIe digital joystick adaptor for using Kempston/Atari/Amiga digital joysticks on an Apple IIe”, available at https://www.pcbway.com/project/shareproject/Apple_IIe_digital_joystick_adaptor_for_using_Kempston_SEGA_Atari_Amiga_digital_joysticks_on_an_Apple_IIe.html

The schematic has been recreated from the board file, and the BC558 PNP transistors have been replaced with 2N3906 transistors (which seem to be more readily available).

BOM– (6 PNP Transistor 2N3906 Through hole) (10 Resistor 1 kΩ, 1/4W Standard carbon film) (2 Resistor 10 kΩ, 1/4W Standard carbon film) (2 Resistor 560 Ω, 1/4W Standard carbon film) (2 Trimmer Pot 100 kΩ Adjustable) (2 Ceramic Capacitor 0.1 µF Decoupling / bypass) (1 Electrolytic Capacitor 22 µF Polarized) (2 Connector DB 9 Male (9 pin D SUB) Panel or PCB mount)

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
