Abacus BASIC-64 Compiler for Commodore 64 – Complete with Manual & Original Abacus Slipcase

This listing is for an original Abacus Software BASIC-64 Compiler for the Commodore 64, complete with the original floppy disk, printed manual, and original Abacus slipcase. The disk is labeled BASIC-64(missing a small piece of bottom left corner on label as shown in photographs) with Abacus Software branding and original serial marking. The manual titled “BASIC 64 – Complete Compiler for the Commodore 64” by T. Helbig is included and appears complete.

The software has been tested and confirmed working on original Commodore hardware. The disk loads as expected, and the compiler operates properly. The original Abacus slipcase is intact and structurally sound, showing typical light storage wear consistent with age but no cracks or broken hinges. This is a complete, authentic vintage software package—not a reissue or copy.

Please review all photos carefully, as they show the exact item you will receive.

Comes with:

• Original Abacus Software slipcase
