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.

André Fachat has connected his Commodore 8296 to an ethernet, running the TCP/IP protocol. To make this possible he extended his CBM computer with a CS/A ethernet board. On the software side he ported the uIP v1.0 TCP/IP stack to the cc65 compiler, and integrated the CS8900A driver from contiki v1. For all the details you must visit the web page of André.

Michau has started a web page dedicated to the CBM-II computers. On his blog you can read about his projects. He transformed a CBM 720 into a CBM 720D, He works on a cartridge that give syou the possibility to connect a IEC disk drive to a CBM_II. And he has demonstrated that a CBM-II can use MS-DOS with the rare 8088 co-processor board.

Matthew D'Asaro has developed a 6540 ROM replacement. The 6540 ROMs are inside the PET / CBM computers. An original EPROM is very hard to get but the 2716 EPROM can replace it. But to make the replacement possible Matthew developed a little adapter, you can build it yourself or order a complete adapter with programmed EPROM.

Cameron Kaiser has updated his KIM-1 information page. Besides technical info on this first Commodore computer Cameron also released a KIM-1 emulator that runs on a Commodore C64. This emulator is called the Incredible KIMplement. It is a true, partial emulation of the original KIM-1 hardware featuring: Powered by "6o6" - a full software NMOS 6502 emulation with all addressing modes, simulated ROM, and simulated memory - mapped I/O. LED and keypad emulation via partial RIOT emulation. TTY emulation (ASR-33 subset) via partial RIOT emulation. SST emulation. 4K RAM expander card KIM-4 emulation with 8K RAM expander card (thus total address space 16K).Revision EPROMs built-in, so you don't have to find a pirated set or download them from your own KIM. Load and save RAM dumps to disk.
