Tell me more about the floppy drive.

append delete Scherier

Hello!
Can you tell me more about the internal floppy drive. I have a tons of 3.5" HD disk at home from my old pc era, but i know, the original commodore 3.5" drive use DD disks, and if you are using with HD disk the data will loosing so fast.
So bad, the 3.5" DD disk is very rare on the market in this time. What kind of floppy drive would you like to use it? I hope you can do a 100% compatible commodore drive, but i hope can use the hd disk as dd without compromise.
I guess i'm not the only one who would like to use the built in floppy drive.
Thank you!
Daniel

So far we are looking to use 1.44mb drives, which will read the 800kb 1581 disks just fine. This is the only practical approach. Of course, if someone knows where to find a dragon hoard of 1581 compatible mechanisms, we would gladly send a Hobbit to go fetch them.

:D thanks

1581 drives are just regular DD drives, nothing special about them except some twisted cables at the connector

Our biggest challenge is find a big supply of a single model, as the eject buttons are so variable in size and position.

I’d rather just have regular SD slots... like 2, or even 4

I believe one will be microSD and the other full-size SD, according to our current plans.

If you're going for a 2HD drive, does that means it'll support an hypotheticaly new 1600KiB format? that'd be really cool, twice the space for the same price haha

Yes, 1.6MB CMD2000 format would be possible to support. Would just require someone to modify the C65 ROM to do it. In fact, our interface should also support 2.88MB ED drives, so even the CMD4000 format should be supportable, but the problem then is finding either a drive or an ED disk to use.

That's quite exciting, is the M65 able to boot from said drive at startup or is it just like the C64?

Does the rom support reading a boot block? And related to this, is there a possibillity to do track loading like we used to do on the Amiga?

Do you plan on using the various C65 roms as is or do you plan fixes and enhancements?

That's a lot of questions, I'm sorry :)

Yes, the MEGA65, like a C65, can boot from floppy. Also you can just hit shift-RUN/STOP, and it will boot from floppy (in a different way), because the default device on the C65 is 8, not 1.

Great!

Where should you get 2.5 '' floppy disks? Either they are extremely expensive ($ 40 for 10) or of poor quality with frequent errors.

Do you want to start your own production of floppy disks?
Would not floppy emulation be better in the long term?

append delete #13. MIRKOSOFT

I was searching in thread - where you read about 2,5" floppy?
My opinion is if there will be placed floppy drive, use 3,5" floppies with support of:
800K 1581 DSDD
1,6 MB FD2000 DSHD
3,2 MB FD4000 DSED
720K FAT DSDD
1,44 FAT DSHD
2,88 FAT DSED

Helo,

We have included the 3.5" floppy drive because without it, the machine just isn't complete. However, this doesn't mean that people have to use disks in it. The MEGA65 includes an SD card, so we expect for most people the 3.5" floppy drive will just make pleasant noises as they access the SD card (it tracks the virtual head movements of the SD card D81 image by default).

im glad you included a 3 1/2, we cant let floppy disks die
i still believe floppy disks are the most versatile medium we have
i used floppies for everything, when cd writing was just coming around; couldnt beat a floppy in price or usage.
still cd's arent cheap. and sd cards arent cheap either.

append delete #16. Hernandp

Nice for retro look but floppies are nowhere to be found today...
I would like a SD only version if it reduces the price by a good margin.

I like the idea of a floppy and I'm looking forward to it. It's right on par with the expectations. Perhaps you might be able to purchase one without the mechanism and get yourself a gotek (works great with .d81) or something of that nature. That might work, too.

append delete #18. Gunstarrhero

i know this is silly, and people i will assume have thought of this. can we serial over to a c64/c64c and use the c64 to access the floppy drive. like a networked floppy, or as a drive 9?
how possible is it to build a 1581 or fd4000 or so from a 1.44mb floppy drive? you need a pcb that runs the rom and everything, like the 1541. have you considered building external (addon) floppy drives? im not just suggesting that, im also suggesting maybe the option to link c64 to c65 for 3 1/2 access and maybe you will consider an fpga based 3 1/2 floppy drive for the c64 in a line of products of yours, maybe you can get someone involved/ ask someone?
it would be a neat cost effective solution for high capacity disk on the c64, and a nice bonus to add another floppy to the c65. i know.... SD... im just all about those floppies.

i know the c65 is also going to support ethernet. i always thought it would be neat to see a network "drive for the c64 that supports ethernet and modem, as well as serial networking from c64 to c64 etc to c65. all in one of those stylish c64 floppy drive cases (1541-II/1581)

i would be good to have a priority system like that either way, maybe even route? (i know thats askin a bit too much, nice led/lcd face. status indicators. perhaps a contoller that initializes on the system at power-on/boot from a linked serial cable to the 1541/1541-II disk drive or so; c65 (this is just an idea, i know there are other solutions, the point is something this size; will do much more than those other ethernet solutions for the c64) on/off power switch (had to save the best for last)

if you know someone who would be interested in something like this either way, please let them know.

That's a neat idea. I guess that, too, is on par with what my expectations were after the fact. I personally like the idea of making this with the expectations that were set out from the get go and sticking with that. Then the community getting in there and getting their hands dirty with the classic open source environment we had back in the day -- build cool addons, express ideas, learn, and have a great time doing it. I really hope the put just enough in it to get the juices going for hardware and software ideas. I think this project is an incredible launching pad for digital literacy and hope it catches on like it did when I was 10 and with my 64. I was doing things with that kit that had everyone's head spinning for a kid my age. Here's to it! Cheers to the Mega65 ;)
