Nils Eilers is working on a new storage device for Commodore CBM computers with a IEEE 488 bus. The petSD can replace the floppy or hard-disk and uses a SD memory card for the data storage. He has made a working prototype with an ATmega 1284P, IEEE 488 bus drivers, real time clock and a serial-USB-converter. At this moment the following features are working: load, save, directory, disk-status, mount a d64 image and disk changes. You can follow the progress of the petSD on the web page of Nils.

Jac Goudsmit has started a new hardware project. He is going to build a modern version of the Commodore CBM/PET computer. He uses a modern programmable Propeller chip in combination with a real 6502 processor on the ProPeddle circuit board. The ProPeddle circuit board is placed on a GadgetGangster Propeller Platform motherboard to complete the system. You can follow the progress of ProPeddle on the blog of Jac.
