Vipersoft BASIC
Notice that this cartridge has an internal tape port, like the one found on AstroBASIC. The owner of this cartridge is not sure if the mini-jack port functions for either or both loading programs with :INPUT (for 300-BAUD) or LOAD (for 2000-BAUD).
Paul Thacker made some brief notes about this Vipersoft BASIC prototype cart on June 19, 2014. They are here.
