This utility is a good one for sorting files on SD memory card.

Thanks.

MB4C+ revised and enhanced for..

Now user can select SLOT#4 or SLOT#5

It isn't needed but some of user suggested and applied.

If S/W is upper ; SLOT#4 

If S/W is down ; SLOT#5

'Reset' hides the mocking board

When the user pressed 'Reset' and tried to reboot, it stopped on $c400 cause there was ROM code missing cause MB4C occupied there and needed to power OFF/ON or '$C600G'

Now it automatically returns and no more brake stops.

It wasn't a bug, the music construct set requested user to press 'RESET' to stop playing music.. so I couldn't remove MB4c from the SLOT.

but, I gave it up... and now we don't have to bother the brake while restarting.

Internally patched for the Prince of Persia.

I got a report that he couldn't run The Prince of Persia

I didn't believe before to test it but, I tested it and found he is correct.

It has a very strange hang while loading and doesn't start...

it made me research some more and now I can make it work with it.

I will consider the software cause it looks like a kind of bug.

And I will modify the position of screw holes for IIc 4000 after that we could have only one version of MB4C+ for all of APPLE IIc(+) computers.

Thanks, friends and customers..

Have a good day

Dear friend and customers,

I'm updating the PS2 keyboard adapter series.

APPLE][, APPLE //e, IIc  and IIc+

all keyboard adaptors would allow present(Original) Keyboard connection and will work together with the PS2 keyboard.

For this,  It needs to be designed a new PCB.

I will post it when It is ready.

Thanks a lot

Mr. Steph made it and sent STL file.

If you have a 3D printer, you can print it and can use it to hold speakers in APPLE //c

When I ready, I will provide those clips for buyers.

Mr. Steph, thank you very much.

Hello,

It contains a few Beatles songs.

Of course, it can be played on SD MIDI ][+ and Passport MIDI card.

Enjoy it

Dear friends and customers,

PS2 keyboard adaptor is good for APPLE II but, now a day the PS2 keyboard also not easy to find...

Anyway, there are still good PS2 compatible USB keyboard.

8310 BOSSTON

With a USB adaptor and then it works great all of my keyboard adaptors.

I think that some of the other  USB keyboards also may work on a PS2 adaptor.

but, the 8310 BOSSTON keyboard is cheap and black and white color one exists.

I tested it on //e,//c and ][+ PS2 keyboard adapter. 

Regard;

Dear customers and friends,

There are a lot of cost issues that happened. for examples, CPLD chips price increased more than 4 times due to this price I stop to make A2 OverDrive cards and I'm not easy to make with well-priced cards. also 65C22 chips price is $10 now it was $3 before when I start developing it. other environment costs also increasing.

And I couldn't keep today's price and from April. the selling price will increase +10%.

Please buy/order before April, then you could have today's price.

Sorry for this.

Regards;

Ian kim

It isn't my code and I found it somewhere...

The code shows the basic Mockinboard control way and ISR(Interrupt service routine).

It isn't a music player just routine to use AY38910 with 6522 chip.

 

Find the Do, Mi, Sol and It is 60,64,67 

So add code as under..

Hi Friends and customers,

I would like to explain how to use SD MIDI ][+ on BASIC.

SD MIDI ][+ card with a sound module, it would make a MIDI sound card for APPLE II.

But, unfortunately, APPLE II has limited Software to play MIDI sound.

SD MIDI ][+ users could play *.MID songs with MIDI Player.

And I believe that someday people would like to play MIDI card for better sound on APPLE II.

I will explain how to use SD MIDI ][+ card on BASIC in this column.

Users can use it in a straightforward way on BASIC.

Play Note and Stop the Note and with proper delay, It could be a MIDI song player.

Let's start to play BASIC for MIDI sound.

Try this code to make Sound.

*You need to key in all BASIC code, it would make you understand it.

** SD MIDI ][+ need to SLOT#2.

10 AC = 49320 ;Slot #2. MIDI control port

20 AD = 49321 ;Slot #2, MIDI Data port

100 POKE AC,19: POKE AC,17 ;MC 6850 init

200 POKE AD,144: POKE AD,50: POKE AD,127 ; Send data

]RUN

Can you hear any sound?

If there is no sound, try to check if card SLOT #2 and Speaker are ON.

If you could hear sound.. it is the easiest way to use MIDI card on your APPLE II.

And Now, let's change the musical instrument to another.

Add this code.

110 POKE AD,192: POKE AD,127

And RUN it

]RUN

And now,

What do you hear?

Did you still think making MIDI sound is hard on APPLE II?

Now, you need to learn the Data that it sent..

The code of POKE AD,( )

You may need to find the MIDI specification.

And What I tested in the code..

NOTE ON

and

Program Change

Thanks

Dear friends and customers,

I think, I really like music on the computer. Such as FM sound and MIDI sound are good for my APPLE II life and like to think about new/better sound cards for my APPLE II.
In fact, I'm not good at the piano... my son plays better... but, still dream of playing the piano with my own song...
But I just I have some talent for making hardware but not good for playing musical instruments...  ;(
If Someone makes a good melody it would be always welcome to the world and then could play the melody on my APPLE II.

The SD MIDI II+ card was discontinued for so long time and need to make another batch for my friends and customers.

In this version of the SD MIDI ][+ would be just a little revised.

Before, I considered it a lot but, I'm not sure if someone would like my idea or just let it be a new trial for fun so just revise the version.

I received the prototype PCB and tested it. works as I expected.

Now, I'm thinking about which color would be good for this card...

Anyway, Please wait 2 more weeks then I could start to make the commercial cards.

Thanks for waiting.
Ian
