Amiga SDBOX BayA made.

Finally I managed to finish, this excellent product, specially designed for Amiga 500 smooth, kick 1.3, based on niklasekstrom's project.
 
The BayA kit includes some tricks and a completely redone and simplified PCB...
 
As you all know, the basic Amiga 500 has no peripheral other than the floppy drive, if you no longer have floppies, you have to start navigating between friends or serial / PC solutions ...
 
SDBOX is the right tool to overcome these problems, moreover, you will have a real external storage easily transportable on a parallel port ...
 
SDBOX also works on Amiga 1200/600, therefore it is the perfect solution for those who use CD-ROM (pcmcia) at the same time and want to transfer files or make floppies ...
 
Very compact and extremely robust, it requires an external power supply (via USB cable) and a 100% compatible microSD is needed. To avoid problems I used sandisks with a small partition called "SAFE MODE", that is 100% tested by 200 MB on which I played for a moment with the cluster etc .... If you want you can increase it (1gb) and format it traditionally without playing with it too much, the initialization times are reduced a lot, but it happened to me that the same make and model, with traditional and larger partitions, then it was no longer seen ...... My advice is to make a copy of the SD in endowment and then do all the necessary tests ....
 
My BOX comes with everything you need, including a BOOT floppy, which contains the essential files to initialize the microSD, both for A500 and A1200 systems. There is a readme.txt file with the info to use the product in 1 minute, also in the supplied SD, you will find some very useful utilities, tested on Amiga 500 base (filemanager, xcopy, .adf etc.).
 
Amiga 500 works with kick 1.3, therefore all the utilities or programs you want to install on the microSD, must be for that kick, if the programs require libraries, they will be copied / installed on the BOOT floppy.
 
Working with various ASSIGN, you can probably use it to the fullest (trying to almost completely eliminate the boot floppy), but these are tests still to be done and in any case the floppy is essential, since Amiga500 does not boot from parallel port .. ...
 
Through SYSINFO, you can do speed tests, on the 500 smooth I have reached 200kb / s and I assure you that you will not notice ANY difference between SDBOX and a PCMCIA in creating .adf.
 
The programs provided are quite light and start very quickly, it is not the solution to start games in .hdf format (harddisk for emulators) the limits are due both to the performance of the machine, and I also believe to an incompatibility with the drive itself for managing the port parallel..
 
Theoretically it would be possible to install programs that would normally be installed on an Amiga 500 with HD, I leave you the details .........
 
In summary it is definitely a very useful and extremely well done system (done by me) :-), suitable for quickly creating .adf floppies on a real machine, it is seen as simple HD, has a good transfer speed and allows you to keep free PCMCIA on 1200/600 machines ...
 
The main purpose of my project is to make .adf (floppies), but it can also be used for something else ...
 
 
UPDATE: it happened not to recognize the microSD supplied as standard .. The defect manifested is that when the MOUNT is launched, the SDBOX LED flashes but does not open the SD-DRIVE icon. This anomaly has been solved by forcing the reading of SD0 using a DOPUS type program. If there are errors, repeat this forcing, on the second or third attempt, everything is working correctly again, even turning off the machine.
UPDATE: I have prepared an emergency disk to solve the above problem ..
This disc launches the SD and then using directoryopus (inserted in the disc), you can perform the operation described above.
 
 
 
Good retro tinkering,
 
The Shark!
 
 
 
Trobleshooting
 
SD-BOX insufficient power supply.
 
From the parallel port of the Amiga, a signal comes out that can turn on the LED of the SD-BOX (slightly lower than normal).
This condition does NOT allow the adapter to work, make sure the USB cable is well inserted and that the power supply or PC are working fine ...
You can check by disconnecting the SD-BOX from the Amiga, in this condition the LED of the SD-BOX must remain on.
 
 
SD-BOX does not see the SD
 
if you use the SD supplied (partitioned in safe mode), use the emergency disk provided, activate the SD as usual using the usual commands and launch DirOpus (read the instructions on the disk) in order to force the reading of the SD.
Make several attempts, if the SD-DRIVE icon does not appear, remove and replace the SD card and repeat the procedure. At this juncture, check how much the SDBOX LED blinks, if it blinks for a short time, insisting, it should initialize it. If it blinks for a long time, it could be a mechanical problem of the SD reader, remove and replace the SD card and redo all the tests.
 
CLEAN Workbench 2.1-3.14
 
If you use clean WB, any version, you need to install FAT32 under L: (follow the product instructions)
and check for parallel.device under DEVS:
On the supplied boot floppy, there are all the necessary files to copy.
