Home of the custom SIO2PC/10502PC Serial Interfaces for the

ATARI 8 bit Computers

SIO2PC /10502PC are two simple yet very important hardware upgrades that give your 8 bit Atari computer a new lease in life. They are two small devices that connect your Atari or your 810/1050 drive to a PC using their SIO port and the COM port on the personal computer.

See more photosWith SIO2PC, the personal computer acts as a peripheral to the Atari, just like your disk or tape drive. In this case however the PC is seen by your Atari as a large and fast disk drive, actually up to 8 large disk drives. With the appropriate emulation software you can boot your Atari from one of those high speed drives (up to 3x faster than your regular floppy) and use the other 7 to store/retrieve/archive your software and your data. No more long waits for your favorite game/application to load or DOS to boot. No more flipping through 100's of floppies. It puts your whole library of ATARI software online, ready to be used by a few clicks of the mouse.  And with most of the Atari software now in public domain, you can download and enjoy all those titles you never had a chance before.

You can also use the internet connection of your PC as a virtual modem to the Atari communication programs, and print to the printers connected to the PC from your Atari software.

See more photosWith 10502PC, and the appropriate emulation software the personal computer can access your Atari drive to copy files or whole disks into Atari disk images. Not only your regular disks, but also copy protected disks can be copied and stored in the PC's large hard drive and later accessed from your Atari through SIO2PC just like you would normally access them from your real Atari drive. The emulation software can even emulate the copy protection schemes found on the copied Atari disks. 10502PC can also be used to write (unprotected) disk images back to a real floppy.

As you can see those two hardware devices can breath a new life into your aging favorite home computer, just as you thought that they are now completely obsolete.

So don't miss out the fun, get your hardware custom built and delivered to your door in just a few days.

If you're new to the concept of using a PC as an Atari peripheral emulator please see this page for more in-depth information. Note that SIO2PC has evolved since that page was written but the basic idea behind it remains the same and lives through this day.

If you're familiar with either or both hardware, then you will be pleased to know that now you can custom build one to your needs, through our "Build your own SIO2PC" or "Build your own 10502PC"  pages. You can view more photos of both interfaces here
