mhhh why ?

Jeff,

because the community might help in developing new converters for some file formats. For instance, It would be great if I could use your floppy emulator in my TRS-80 model III.

So you don't care about hfe file format

.
What do you want to know is how write a new loader plugin in the software. look at common\plugins\jv1_loader in the sources tree archive for example.

which file image type do you use with the TRS-80 model III?

Jeff,

thanks. JV3 and DMK are the most used file formats for TRS-80 Model III. Having JV3 available would be great.

Another topic. There is a Chinese guy in ebay (Sure electronics) that can make the PCB cheaper than any other dealer in Brazil. He needs the project's Gerber files. What do you think about making these files available?

Sorry but the actual sdcard pcb is a "piece of crap" (too big, one layer, too much jumper, overheating regulator...) and should not be produce. It's a prototype/testing only pcb. So i will not release the gerber of this version.

where i can found JV3 images on the net?

Jeff,

About the "piece of crap", I don't agree with you, but you are the boss.

Some JV3 files are:

http://www.datacassete.com.br/softwares ... dos16c.zip
http://www.datacassete.com.br/softwares ... esenho.zip

Thank you very much for helping me.

Gustavo.

Does this mean that you are planning to create a new PCB? If not, how long you will support this revision with firmware updates?

BTW, does the SD card version support 1024 bytes per sector in MFM format, 500k bitrate? We haven't found any floppy emulator supporting these settings so far so your project is our last hope.

Thank you,
Sven

Yes i am working on a new design (AT91SAM7S based), and a new pcb will be made. Once the new design is released, the actual design (PIC18F based), will not be updated.

The actual design support the 1024bytes sectors, but in read only mode.(the write support is ok for 256bytes and 512bytes sectors).
The future design should support any sectors size (at least 128/256/512/1024 & 2048bytes sectors) in read&write mode.

Thank you for letting me know. Don't want to put any pressure on you, but do you think that the new design may even be released in 2009, or do you expect to need much longer than this? I am asking because I am working on a project where I do not necessarily need write support for 1024 sectors (but it would be nice though), but if the design changes very soon I would wait until the new one comes to light.

Anyway, merçi beaucoup for your absolutely stunning project !!!

Best regards,
Sven

What about the copy protection stuff? which ones are currently supported?
i tried out some games (Dragons Breath, Magic Lines, Super Hang On and Xenon 2), they all worked perfect as IPF with HxC USB, but then i converted them to HFE and nothing worked.
Turrican 2 worked, but i think it only used flakey bits, and nuclear war too.

No protection supported.
i had to make some choices to reduce the cost of the device.
In fact most people don't care about ipf/stx, but care about the price.

Turrican used the long track protection.
