RetroFloppy offers a selection hard-to-find serial cables and diskettes. Jump to:
Apple IIc, Laser 128 null modem
Approximately 6 feet long, made with shielded cable. Converts the Apple IIc or Laser 128 modem port to a female DE-9 connector, typical on older PCs with RS-232 serial ports. A newer computer will likely also need a USB adapter, below.
Apple IIgs, IIc+, LC III null modem
Approximately 6 feet long, made with shielded cable. Converts the Apple IIgs, IIc+, or the Mac LC III modem port to a female DE-9 connector, typical on older PCs with RS-232 serial ports. A newer computer will likely also need a USB adapter, below.
Apple ///, Super Serial null modem
For connecting an Apple /// to a typical PC port, this cable has a 25-pin male DB25 connector on one end and a female 9-pin DE9 connector on the other. It is wired as a null modem. It could also be used with a Super Serial card with the jumper block on the Super Serial card pointing towards the word "Modem." See here for details.
DB25M to DE9F Adapter - Straight Through
For connecting an Apple Super Serial card to a typical PC port, this cable has a 25-pin male DB25 connector on one end and a female 9-pin DE9 connector on the other. It is wired straight through, and so requires the jumper block on the Super Serial card to be pointing towards the word "Terminal." See here for details.
USB to RS-232 Adapter - Macintosh or Windows
Converts a Macintosh or PC USB port to a male DE-9, RS-232 connector. This, coupled with one of the null modems above, will complete the circuit from a modern Mac or PC that only has USB ports to an Apple II. This adapter has a built-in 3-foot USB cable, and each adapter sold is tested specifically with ADTPro to ensure compatibility.
This adapter uses the FTDI chipset, not the lower-cost Prolific chipset which is usually poorly cloned in other very low-cost adapters. The FTDI chipset has proven to be much more reliable, and is the reason we stock this specific one.
Drivers for Mac, Linux, and Windows are available from the manufacturer's website.
Apple II, Apple /// ADTPro Software Diskettes
ADTPro is a software program that will transfer entire disk images from Apple II and Apple /// computers to modern computers over one of several communications methods:
- Serial cables (available above)
- Audio cables
- Ethernet network (with Apple II Uthernet card)
ADTPro is open source software, and is available free. The price of this item is only for the physical diskette to be created for you. See the ADTPro web page for complete instructions. You will need to download the server side of the software from there as well.
