New hardware for the C64 appears like it was still a production machine. It’s amazing. This time I’m talking about EasyFlash cartridge. EasyFlash has existed for some time already, and now I got myself one of those.
I bought mine fully assembled from Mike Betz via Lemon64 Forums. These carts are nicely finished with quality case, stickers and all. And of course I peeked inside – the case hides the real quality of the cartridge; Professionally made PCB, all socketed chips and flawless soldering make up these EasyFlash cartridges.
So what’s EasyFlash?
EasyFlash is a Flash memory based programmable cartridge for C64. Basically it works like any original game or software cartridge except that the cartridge binary (data, or cartridge image) can be easily erased and rewritten. And this is done using no other tools than the C64 and software called EasyProg. Any standard (8k & 16k) or Ocean Type 1 (128k & 256k) cartridge image can be written into EasyFlash and it effectively “becomes” that cartridge. Read the rest of this entry »

It’s been already a while since I got the uIEC – one of the available hardware running the sd2iec firmware. I did some experimenting with it on how to make the best use of it if the nicely accompanying JiffyDOS is not present. I posted my experiences at Lemon64 forums, but I thought it would be nice to share them here as well. Still, you might want to read that instead for shorter, less detailed description.
Note that I’m describing sd2iec-firmware being used on uIEC/SD-hardware with Commodore 64. Many different hardware combinations are possible.
With sd2iec loading files from the SD card’s root folder is like loading files from a floppy disk. The very basic loading procedure is exactly the same – except that the default device number is not 8 but 10. So LOAD”$”,10 or LOAD”GAME”,10,1 works just like one would expect.
Things get more complicated if you want anything more. Something like to enter a directory on the SD card or to mount a .d64 disk image. A real Commodore disk drive wasn’t designed for such things so you don’t even have the commands for something like that. Since uIEC is connected only to the serial port of C64 it can be interfaced only using the IEC bus. Enter the command channel! Everything like directory navigation, disk image mounting and device configuration is done by sending drive commands over the command channel. Read the rest of this entry »

Few days ago I got myself a uIEC/SD ordered from Jim Brain. I also bought a set of JiffyDOSes which should make a perfect match with uIEC. Even though I am a happy 1541 Ultimate user I wanted to get familiar with this device as it and other SD memory card applications using the same sd2iec firmware seems to be very popular. Also, this one can be nicely used in Commodore machines where the C64 Expansion port is not available. Read the rest of this entry »
