SDSmart.ROM

Hi friends,


It took long time to have new version of firmware.


This version having new features as under.


1) It supports Read Only function. Read Only Floppy with FDD image file. 

To do this, you need to set as Read Only (*) on your image file then It works as write protected on FDD.

Each FDD works as followed the FDD image R/W status.

it works only *.NIB file.

Please test it and let me know your feed back. :)


2) Support image file Write protect by Dial

Long press EXIT will toggle loaded image R/W <> R/O


3) *.PO FDD image file support. *.PO image file have prodos sector order on sector. it has different sector order compare to *.DSK file. I didn't test it much.. just checked it can read and can run with my file.


How to updates? please refer this.

If you have any question, please email me.



Thank you very much.

Dear Friends,


If you have difficulty to use Smartport HDD on your APPLE IIGS,


Please try it after Unload D1: or 'Your card' of SLOT6 on IIGS control panel.


If some image file in D1 for autoboot, some cases failed to detect Smart devices.

I'm working on it.


* Tested *

My connector got faulty not the firmware.

Anyway, you can use the latest firmware.

Thank you.

Firmware V1.18S

◆ SD Smart Drive / 2016.06.20 10:00

Dear customers,


I updated firmware for SD Smart Drive.

New version is V1.18R and fixed some minor bugs and enhanced to detect Smart device on APPLE IIGS.

Please download it and update for your Smart Drive.



Version 1.18S

SDSmart.ROM



How to update


WARNING
Your APPLE2 must not lose electric power while firmware updating.  
If this were happen, the firmware couldn't completed and may fail to to restart even firmware updating may fail. In this case, You need to send it back to me for re-building codes. 
(Free of charge to fix this issue but, shipping costs will be your responsibility).
If you are ready to update, please read it first and follow this instruction.
1) Power OFF APPLE2
2) Remove the SD Memory card (Present working SD Memory card should work fine)
3) Copy the new firmware file (SDSmart.ROM) to  root directory.
4) Return the SD memory card to SD Smart Drive.
5) Push Dial button(SELECT/YES) +EXIT button simultaneously, then power ON the APPLE2.
* You can use terminal command as 'firmwareup (Enter)'

6) Then release a few seconds later. You may see on LCD as 'system check..................................'
6) A while later, SD Smart Drive will restart
7) Reboot your APPLE2 and check if the version is properly updated.
If done properly, Now, Enjoy with new version of firmware.


History of V1.18S

-'No file' error message shows the reason.

-Smartport detection method changed for APPLE IIGS.

Before some of cases, failed to detected on IIGS. 

It was happened when power ON FDD boot and Smartport drive status requests.

It doesn't affect on IIc and not works good.


History of V1.18R


- Enhanced the SD Smart Drive detection on APPLE IIGS.

- Locked FDD file showing on the Terminal when Loading it.


History of V1.18Q


- RAM test method changed and it doesn't destroy present data in buffer.

- Serial recovery changed for better recovery to 115200bps.

- Status message little changed.

- Smart Drive detection improved.


Any other bug or request are welcome.

Thank you

Ian Kim

Do you want faster a Smart Drive HDD?
Of course, that is better than slow. :)

We don't want wait long time for booting or run a program.
That's what we want to have.

Hence, I'm keep going to develop newer faster Smart Drive.
Much faster MPU will kick your APPLE II run faster. 

The new MPU got 5.9 times faster and 32bits processor.
So, also data processing could be much faster that AVR.

I used this MPU for new brain for new smartport device on APPLE II.

In the beginning, I got some difficulties cause this processor isn't not familiar not like the AVR.
After lots of times tries, I could make it read the SD card and could it boot the Prodos 2.0.3. :D


Of course, performance increased and boot was faster. it takes around 2.44 secs to boot on APPLE IIc.

and took less than 2 secs on APPLE IIGS.


And tested the GSOS booting too.




How long takes to boot?

It takes about 1 minute 12 seconds.

As followed analysed the package times, It is really faster than AVR one.

AVR one takes around 1min 42secs but, It speed up and less 30 secs spent for boot it up.

And you may guess other device was faster?.

You have to test same image file some image is smaller for boots.


Prodos booting 2.03; + 48% faster on APPLE IIc

Data Reading 65 blocks(each 512 bytes): +69% faster


GSOS booting: +41% speed up

DISK reading performance was increased a lots, but overall of booting time doesn't decreased a lots.

As followed my measure, 

512 bytes Reading took lessthan 1ms(average).


Anyway, it wasn't faster as 5.9 Times.

Why?

Because, APPLE took time to reading data and buffering and analyzing packets to load into the memory.

And the SD card got speed limit,

AVR one using 8 Mhz SPI 1bit mode, but this testing board using 24Mhz and 4 bits mode.

So, estimated Reading speed could have 3 x 4 = 12 times

Other packet processing also may took 1/5.9 AVR one.


And I counted total data blocks for GSOS.

It required 1895 blocks for booting.

What does it measn?

Each block took less than 1ms, hence if took 0 seconds for prepare the packet, it can only reduce 1.895 Second..


So, I can say, this new Smart port Device is one of best one.


It is only Reading device now, but, some days later I can complete Write function.

Read only HDD isn't useful and not proper device.


Another concern about disk management,

I don't like to use DISK Partition for disk emulation.

Programming is easier and simpler than file type access method.

But, It has a big limitation of using HDD. 

Because of partition method, It can have for a partition.


But, I'm using file based Hard Disk.

It doesn't have limitation of HDD to hold and no required partition jobs.

Just choose HDD image file for HDD emulation on your APPLE II.

and replace it what you want and simply have time to enjoy your APPLE II.



For now, I have to complete some other one such as Writing on SD card and User interface.

Please keep watch and wait for newer and ultimate fastest HDD for Smart port on your APPLE IIc,IIGS...


I've bad English but, hope you understand what I want to say. :)


Thanks for your reading.
