Dear friends and customers,

Please update your card firmware to V2.76B.

It has been internally patched as under.

But, If you don't use an LCD dial, you don't have differences.

 

What was updated

Patched on Making new Blank DISK image creating (Name selection was limited but now up to 99 disks)

Simplified internal routine for less firmware size. (It would help for further reserved function)

 

How to update

1) Copy the file on your SD memory card in Root location.

2) Please update by '*' on the Boot Menu.

3) After finished, Please check if the firmware version changed on the Boot menu.

4) Reboot your APPLE II and use it.

 

 

** Notice for firmware V2.76x **

From this version, the FDD reading method was changed and some of *.NIB files may read at a slow speed.

In this case, It needs to convert the DISK SKEW of the NIB image file.

To solve this slow speed issue, Simply copy the image to self by COPY ][ PLUS.

It will help to read at a good speed.

If you having any other troubles, please let me know.

Dear friends and customers,

Firmware for SD DISK][ Plus has been newly updated.

 

Now, Also working well on the Lemmings game program.

 

In this version, internal improvements have been made to better support the DISK COPY program.
Below marked OK DISK COPY programs work well.

The above programs are disk-related utilities that are mainly used.

You can easily make a NIB file created after copying it, to archive or distribute it on the Internet.

However, the negative symptom was found

Some NIB images read very slowly.

it comes due to different virtual DISK spinning.

 

In this case,

Use a DISK Copy Program(such as 'COPY ][ PLUS 5.1' ) and copy the DISK to self. 
In other words, Overwrite the Image by copy to DISK B --> DISK B 

 

How to update firmware!
Put the this SDBIOS.ROM file in the root of the SD memory,
Then proceed with the firmware update on boot menu.

Im glad to announce new firmware V2.50B for all SD DISK][ Emulator users.


sdbios.rom


This version have useful function as under.

1)  XMODEM file transfer protocol now support, 

its old classic protocol but, simple to apply for small MPU system. I applied it for you.

Now you can send or receive image file without open the APPLE// case to get SD memory card.

For file transfer, you need a terminal software which have XMODEM128-Checksum protocol such as the Tera term. But, unfortunately the Blueterm doesnt have XMODEM protocol so you cant send/receive file thru your android phone.



2) You can change speed of serial baud rate.

115200baud/57600baud/19200baud/9600baud support

But, there are some technical issues please read carefully.

Slow baud rate as 9600, it may have error while FDD emulation. It may missing some information to APPLE2, After set it.

Ihas lack of time to receive another track moving signal from APPLE2 and may error cause of fail to moving proper track. so please avoid this speed to use FDD emulation. Higher speed doesn't emulation fault. it doens't effect on HDD emulation.

Anyway I will remove track log to avoid failure on next version of firmware.


115200baud it was default and it has file receing issue.  due to 16Mhz frequency cant make exact 115200bps. it has about 7% different and some data missing will occured and will request packe offten so will slow transfer to APPLEII. Hence, I recommended to set 57600baud . It doens't have any problem using XMODEM protocol and FDD emulation too.


3) Some of terminal log/status messages are changed for easy reading.

There were some garbage while showing, and I tried to adjust for better view. It wan't critical to any operation but, little might be annoy.


4) Terminal key-in routine was changed. I used really simple keyin routine for reception commands from serial line. but it works better now and you can use backspace to delete your just keyin command. It is good to me.


5) Status command shows more information of SD DISK][ Emulator.

 

6) File selection bug fixed.

 

7) Other small bug fixed.



How to send a file from a PC to a SD DISK][:

RX filename.ext or UP filename.ext

then select protocol XMODEM128 Checksum and 

select a file to send.

 

Then select protocol XMODEM128 Checksum and select a file to send.

 

How to receive a file to a PC from SD DISK][:

TX filename.ext  or DN filename.ext


For stable file transfer, I recommended 57.6K baud rate. 115.2K baud also works 

but, will resend packets occasionally, so please set to 57.6K baud or slower. (recommended)


The terminal software on your PC side, I recommended you use TeraTerm.

I have tested with it and it works very well.


*Other information

Important! 

You also need to configure the Andriod Blueterm application.

If you don't  change the configuration, the Blueterm app can't send the "Enter" code even if you hit ENTER. 

So please change the following below.

On the Blueterm -> Preferences -> Set to Replace by CR(0x0D) [x]


Important! 

You need to pay attention when you set the Baud rate with the Bluetooth dongle board.

The Bluetooth board is isolated serial equipment of the SD DISK][.  Emulator and baud rate is also isolated to SD DISK][ Emulation,

so it doesn't  automatically follow the SD DISK][ Emulator baud rate. I added some AT commands to help make it follow(SYNC) with the SD DISK][ Emulator, but you'll need to use the Setbaud command to insure synchronization.


To synchronize the baud rate to the (optional) Bluetooth dongle board, the board must be set to "wait" status. (Red LED blinking) So you'll have to disconnect the Bluetooth connection via software setting. (not by physically removing the small Bluetooth board!) You should see the "ready" mode LED blinking on the Bluetooth dongle board. Then you can try the SetBaud command and the bluetooth configur

ation should automatically follow by automatically setting the correct baud rate.


As mentioned prior, there is one limitation to use 9600 baud. It might have data errors using FDD emulation, so it isn   recommended to use 9600 baud with FDD emulation. (only)  HDD emulation is not effected.



How to update the SD Disk][ firmware:

 

WARNING

Your APPLE][ must not lose electric power or be powered down while the firmware 

is updating.  If this happens, the SD Disk][ may to fail restart, or you won't be able to update firmware anymore.


In this case, please return the board to me for re-programming.

(Free of charge to fix this issue but all shipping costs will be your responsibility).


If you are ready to upgrade, please read (first) and follow below carefully.

 

1) Power OFF the APPLE][ and open the cover of your APPLE][.

2) Remove the SD Memory card only, leaving the Disk][ board in the computer. 

(Present working SD Memory card should work fine)

3) Copy the firmware to ROOT directory of SD Memory card. 

4) Push Dial button (YES) + Exit button simultaneously, then power on the APPLE][.

5) Then release a while later. You will see as 'system check..................................' on the screen.

6) A while later, SD DISK][ Emulator will restart.

7) Once the SD DISK][ restarts, re-programming of the SD Disk][ card is complete.Re-start your computer to enjoy your updated SD Disk][

( Thanks Mr. Bob Brown ) 

 

 

 If you have any concerns, please let me know.

SD DISK][ Emulator Firmware V2.50A

 

안녕하세요. 이안입니다.

 

기다리시던 새로운 펌웨어 버전 2.50A가 나왔습니다.

 SDBIOS.ROM

이번 Firmware에서 가장 크게 달라진점은 

이제는 XMODEM 로토콜 지원으로 화일 전송이 가능합니다. 게다가 PC Bluetooth 동글을 설치하면 무선으로 화일 송수신이 가능합니다. 간단한 image파일은 SD 메모리카드를 빼지 않고도 관리가 되어, 좀더 편리하게 SD DISK][ Emulator를 사용할 수 있게 되었습니다.

그리고, 안정적 화일 송수신을 위하여 시리얼속도를 변경할 수 있는 명령이 추가되었습니다.

기존 화면에 표시되는 디스크 동작 메세지가 조금 바뀌었습니다.

터미널 입력 루틴을 개선하였습니다.

 

파일 송수신 방법

PC -> SD DISK][ Emulator로 보내려면 

RX filename.ext 

입력 후 터미널 프로그램에서 XMODEM128 Checksum 으로 화일 선택하여 송신하면 됩니다.

 

SD DISK][ Emulator -> PC로 전송하려면

TX filename.ext 

입력 후 터미널 프로그램에서 XMODEM128 checksum으로 파일 정하시고 수신하면 됩니다.

명령은 UP(Upload)  받으려면 DN(Download)으로 해도 됩니다.

 

화일전송은 57600(포함)이하로 시리얼 통신속도를 설정하셔야 원활하게 됩니다. 115200bps도 수신을 잘 되나, 송신이 원활하지 않습니다.

 

그리고, 터미널 프로그램은  Tera Term을 권장 합니다.

 

* 기타  사항

! 안드로이드폰의Blueterm설정 변경이 필요합니다.

설정안하시면Enter키를 제대로 입력받지 못합니다.

Tera term은 문제가 없습니다

BluetermPreferences에서 Outgoing LF(0x0A)

-> Replace by CR(0x0D) set설정하십시요.

! Bluetooth 옵션보드 사용시 Setbaud명령시 주의가 필요합니다.

 Bluetooth 옵션보드와의 연결을 끊은 후  Setbaud명령을 실행하셔야 블루투스옵션보드도 시리얼속도가 변경됩니다.

 

 

* 기타 의견이나 오류가 있으면 알려주시기 바랍니다.

 

Firmware update 표준 방법
 

!Firmware 업데이트는 신중하게 하셔야 합니다. 업데이트 중간에 전원이 꺼지거나 다른 버튼을 조작하여이나 기타의 이유로 중간에 중단되면 SD DISK][ Emulator 구동이 불가능 할수 있습니다.  이에 다른 작업은 절대로 하지마시고 업데이트 작업을 하시기 바랍니다.


1) SDBIOS.rom 화일을 SD DISK][ Emulator에서 읽혀지는 SD 메모리 카드의 Root 디렉토리에 SDBIOS.rom 복사하고 Emulator 꽂습니다.
2)
APPLE2
OFF합니다
.
3) Dial
버튼(Select/Yes) EXIT/No 동시에 누른상태에서 APPLE2 켜십시요.

터미널에서 System check... 나오면서 update 진행 됩니다.

업데이트가 끝나면 새로 시작되나, 이때 Reset버튼을 눌러 새로운 Version으로 제대로 시작하는지 확인하십시요.
 

APPLE2OFF/ON하지 않고 업데이트하는 방법


1) SD DISK][ Emulator에서 읽혀지는 SD메모리 카드에

Root 디렉토리에 SDBIOS.rom 복사후 Reset 눌러 메모리가 인식되는지 확인합니다.

2) Emulator control 보드의  Reset + Dial 버튼(Select/Yes)+ Exit/No버튼을 모두 누른 상태에서 Reset버튼 살짝 떼시면

System check... 나오면서 update 진행 됩니다.
업데이트가 끝나면 새로 시작되나, 이때 Reset버튼을 눌러 새로운 Version으로 제대로 시작하는지 확인하십시요.
