This sounds cool :) But a little unclear. Can you please type a bit slower for us slower folks :D and explain a bit more ?
We will be able to connect this SCP to a Replay board, right ? And a PC floppy to it, right ? And read/write real floppies ?


Technically, any device that has a CPU of some kind can control this device.  Yes, you can use any real 5.25" or 3.5" floppy drives with this device to read/write various disk formats.

Thanks Mike!

Before production boards were started, I made a change to my SuperCard Pro project to make the floppy bus fully bi-directional.  This means that besides being able to use a real floppy drive, it can also emulate a floppy drive.  So, we can use protected disk images via the built-in microSD card slot.  Besides USB (using a parallel FTDI USB FIFO chip), there are also two 1Mbps serial buses that can be used to transfer data.  So, theoretically it should be possible to boot protected disk images from an SD card and not require a real floppy.  I am just starting the drive emulation support, but since its mostly hardware driven (capture/compare w/DMA) I don't think there is too much to do to make it all work... famous last words!  LOL!

True, but for me, I wanted something I could put inside of my A1200 to replace the floppy drive, and still be able to play Shadow of the Beast from "floppy".  :)

The term "soak test" comes from the test procedure that focuses on long term thermal testing - where parts can be "soaked" at varying temperatures during the test.

NASA uses this frequently with their boards that go outside of our atmosphere (heat soaking/cold soaking).   I used cold soaking for my project with James Cameron's Mariana trench dive.  The electronics I designed for that had to withstand sub-zero temperatures at over 16,500 psi.  They actually were tested (in a chamber) to over 18,000 psi, sub-zero to +150F - up and down in pressure and temperature to see if they would fail.  No failures in 3 sets of boards... surprised me for sure.

Q: Can I use a real floppy drive with the Replay board?

 A: Maybe in the future, user JimDrew is working on something called the SuperCard Pro
Last year I designed SuperCard Pro, which was suppose to be a simple flux level disk copier that lets you use PC floppy drives to duplicate Commodore 64 and Amiga disks.  That turned into a 25ns resolution disk copier that can duplicate virtually every format and also create images of disks (flux level, so copy protection included).  In the last 45 days I caved in to temptation and redesigned the hardware to allow it to not only be a disk copier, but also be a floppy drive emulator. It has a micro-SD media card to load disk images.  It has two high speed serial ports that can be used to control it, transfer raw data, get directories, etc.

I am waiting to get the FPGA board from Mike, and I can look at exactly what needs to happen on the FPGA side to fetch data.  I think the best way to handle this would be interface the data stream into the PAULA's data separator (providing PAULA is emulated at a low level).  If there is PAULA emulation, then there should be no problems running any type of copy protection you can throw at it.  If the PAULA emulation is limited, it still might be possible to inject the properly timed MFM data into the system.

I wrote many disk copiers and designed several disk copying hardware devices for the Amiga, so I am extremely familiar with what is necessary to accomplish this.  So, hopefully I can work with Mike to provide not only emulated disk support, but also real floppy drive support since SuperCard Pro can do both.

Hi Jim,

Any possibility of this being expanded to include other platforms on the FPGA Arcade (e.g C64/ST)?


Already done.

Mike,
 
Please work with Jim to help him provide SuperCar Pro support for the FPGA arcade. This would allow all commercial Amiga and Commodore protected floppy based software to be loadable by the FPGA Arcade, providing an IEC bus can be implemented on the FPGA Arcade. Does the FPGA Arcade have hardware floppy support, or is the emulation intended for use with disk images from flash only ?
 
.. Dale

There is an IEC bus on the SuperCard Pro board, along with all of the code for handling CBM disks.

Mike and I have been chatting for a couple months about this.  I am just waiting for my board to arrive to see what is needed.

How many people would be interested in purchasing the FPGA Arcade from a source in the U.S.?  I am considering buying a bunch of them, so I am curious how many U.S. buyers there would actually be.  I would hate to get stuck with a pile of boards!  I figured the U.S. retail (at today's exchange rate) is ~$299 for the version with the SVHS option.  Let me know!  Thanks!

I want one!  But only when I can get 060 with MMU card with it.  I am a developer and I simply must have 060 MMU otherwise it would be a downgrade from my current Amiga.  And I hafta run MuGuardianAngel, etc. anyway.

OK, noted.  Thanks.  I am not sure how far off the 060 daughtercard is.

I'm a US resident that's interested in getting ahold of one.  If it'd be simpler to buy one from Jim Drew (got a Signature Edition planned?) than direct from Mike, I'd be interested...

LOL!  No, I don't have plans for a signature series edition.  :)  I think what Mike has accomplished so far, and the direction this can go, is something that I want to help support.  I know that often times some of the best hardware is also the most difficult or expensive to get when it's not made and/or distributed by a U.S. based company.  So, I was interested in trying to make them more readily available here in the U.S.  I also want to help with development of stuff for the board, and accessories.  If there are only a few people here in the U.S. that want the board, then it probably doesn't make any sense for me to make a bulk purchase of them just to sit on them.  So, I am trying to get a feel for the level of interest for U.S. based people.  I would not offer them to people outside of the U.S. as that would defeat the purpose.

Sorry Blinx - I thought I had caught up with most mails. Mail me again and tell me you are Blinx!

busy playing with my new microscope for SMD inspection ...

I have a 20x/40x/60x unit that plugs into the USB port.  I got it probably 10 years ago.  It was some kind of toy microscope, but the quality is superb and at 60x it's perfect for SMT inspection!

Oh you should see the toy I got in SZ ;) The lens is over a foot long...
LED ring around the end for illumination, and flat screen monitor for viewing.

It's too silly for normal use, the six inch one is fine..

The small one looks a bit like this :

http://www.alibaba.com/product-gs/585367650/Electronic_digital_microscope_Microscope_video_microscope.html

Only downside is the high-res camera is USB only, if I want to use the little screen I need to swap for the one with video out. Being video there is almost no lag, which is useful if you are trying to solder the thing under it.
Anyhow, back to work...

Dang it Mike!  Now I gotta go looking for a replacement!  I would love to get something that was self contained (non-USB) so I don't need a computer.

The market is not big enough for these types of projects to be a 'job'.  I am in the same boat as Mike.  I do my toy projects on my own free time.  Fortunately for both Mike and I, our jobs are closely related with the development of other projects so it gives us the luxury to do snooping for sources and such while doing real work.

Just finished CommVEx here in Las Vegas.  Although it is primarily a C64/128 based event, there were a surprising number of Amiga enthusiasts here too!  In fact, I met a guy who I sold my CD-32 SX-1 to in Portland, OR about 25 years ago!  He apparently has an early FPGA Arcade prototype too.  Amiga One, X1000, etc. machines were in attendance.  I had never seen one of the non-WarpOS PPC setups before.

There was a big interest in the FPGA Arcade.  A C64 core is a definite must for the list of cores.  The more cores available, the more reasonable in price this device will effectively be!

As Mike stated, we have been in talks about distribution.  I have committed to become the U.S. distributor for his products.  I also want to help support development efforts as well.

The reality is that the final touches are being made so that the release can actually occur.  Sometimes the end games goes well, and sometimes it doesn't.  Mike is taking the correct approach and making it right from the beginning instead of something that could potentially need to be returned for mods, or need endless patches.  You don't get a second chance to make a first impression, so please understand Mike's position.

If you are a U.S. customer and want a FPGA Arcade, AND you are not already on Mike's list, please PM me that you are interested.  I am building a list right now, and have started with several people who attended CommVEx.  Thanks!
