이안은 뭐하니?

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

Ian Kim

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.

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.

Dear Friends and customers,

English manual for Mockingboard 4c+

Please refer to the manual for insallation and use.

Thanks a lot

Dear friends and customers,

I glad to annouce this information about the mockingboard for APPLE //c+ is completed.

This board could be installed over the CPU socket same and speaker volume also works as followd the volume control slide.

It was fully tested on APPLE //c+ and works great but, on 4Mhz, It generate higher tone and faster sound. For proper sound, you have to set on normal speed on APPLE //c+.

I ordered PCB for commercial boards and parts. it would take around 2 weeks and then I could start to ship to you.

** Pre-Order will be closed on 28th March **

Included items;

1) MB4c+ board 
2) Two speakers
3) Volume control wire

*It doesn't include 3.5mm AUX cable.

**MB4C+ is compatible with APPLE //c & APPLE //c+

Price; $125

(Preorder closed)

For pre-orders, I will ship it for free but only for below countries.

* Shipping Issues *

Thesedays, I'm having difficulties to ship world wide.
In this time, I can ship only those countries for free of charge.

--Free shipping countries--
USA
GERMANY
UNITED KINGDOM
LUXEMBOURG
ITALY
RUSSIAN FEDERATION
MALAYSIA
VIETNAM
CHINA
THAILAND
CANADA
PHILIPPINES
HONG KONG(CHINA)
BHUTAN
SANMARINO
ALBANIA

For other countries, I have to check if it could be shipped by EMS or UPS and costs would be higher so,  it wouldn't be a free shipping and need additional costs.

For this, Please let me know by email with your address to check the shipping costs.

Thanks a lot

Dear customers and friends,

It was long years have passed since I develope the MB4c.
First time, I really want to have Mockingboard for my APPLE IIc and finally could have Mockingboard for //c computer.
it was really happy experianced and It was enough for me.
And revised some version for perfect compatibility as now.
But, the Mockingboard doesn't work on APPLE //c+.
Physically and logically it doesn't support APPLE //c+.
I received some of email who want to have Mockingboard for his APPLE //c+ and finally I promised to finished it.
Infact, When I develped the MB4c, I also tried to make it run on APPLE //c+ but failed.
APPLE //c+ has own cache for faster run and it working different with  APPLE //c.
Some of friends want a Mockingboard with a memory board.
But, It woudn't be easy due to low space.

Anyway, This is a beginning for APPLE //c+ so let me to complete the Mockingboard for C+ first and consider next step on next version.

Thanks;
Ian Kim

Another Revision of PCB was ordered and I'm waiting for it.

In the first design, I used AY3-8912 and good parts going to hard to obtain so change it to AY3-8910 chips.

And now, 6522 part also getting harder to find good one And more failure rates are too many.

So, Tried it to use 65C22 but it doesn't fit well and needs to change circuit redesign.

Designing a new device isn't simple due to old vintage parts need to be provided properly.

it is harder to obtain good working parts.

Due to a lack of good working parts, I also considered replacing it to CPLD but, it isn't good mate for vintage APPLE II so didn't emulate it and now CPLD is just used to replace some of TTL chips.

Once it finished, I could prepare enough amounts of MB4c board.

Please wait more time for it.

Thanks a lot

Ian Kim

Dear Friends,

This is 2nd commercial version of Mockingboard 4c.

First version was sold out so, I needed to prepare more PCB for Mockingboard 4c.

I little adjust the sound input level and sound doesn't off to avoid OFF popping sound.

And CPU little relocated to upper for easy soldering for me.

Sound little improved and easier to solder by me.

I'm testing compatibility and works 100% as Mockingboard C.

Please wait some weeks for next batch of Mockingboard 4c.

Thank you

Ian Kim

1st Mockingboard 4c all sold out and preparing another revision.

In this version have minor upgrade, Enhanced sound quality.

1st Mockingboard 4c sound little like over driven sound so, I tuned it under proper level, It's little better.

And the CPU socket was relocated to upper for easy soldering. I had hard to solder this area...

It is testing board.

There is no Mute pin but, I will keep the Mute pin even rare used by user.

Ordered another sample PCB for testing..

Thanks for waiting. It will coming soon for you.

Thanks a lot!!

Hi friends,

It is a ZAXXON game with mockingboard 4c support.

You can only find here in my blog and cause I did crack it to make it run on APPLE IIc.

Enjoy it :)

Thanks

Ian Kim

Dear friends,

The Mockingboard 4c is only the soundcard that you can find for your APPLE IIc.

Now, the Frech touch team has started to support MB 4c on their great music.

Please download the Pure noise or just get this NIB image file.

The Original site is here

http://www.ctrl-pomme-reset.fr/french-touch/

Thanks for the great work on mockingboard.

Dear All,

It is a great music program(http://www.ctrl-pomme-reset.fr/french-touch/) and now it can play on Mockingboard 4c.

I wanted to play it on APPLE //c and patch and run on //c.

It sometimes required Manual ON,(Please refer to the manual) then works properly.

I also hope to play others and wait for a newer version for APPLE //c.

Thank you.

Ian Kim

Please refer the user's manual it for Mockinboadr 4c.

한글 메뉴얼; 

English manual;

-----------------------------------------------

----------------------------------------------

I will update when I finished testing.

* Mockingboard can do OFF when it Pressed CTRL+ RESET.

But, from this batch of product, 

It wound't OFF Until Power OFF. It means that If you triggered the manual ON then It wouldn't OFF even CTRL+RESET Pressed. If you want OFF, You have to Power OFF and ON again.

I found The Music Construction Set allow to use CTRL+RESET. So, It would be better to support for Exist Software.

* One general question was Mouse support.

After Manual ON the mockingboard, Mouse can't work together, cause of It is using same slot#4 so, mouse firmware can't be accessed. 

You can't use Mockingboard and Mouse at the same time until Power ON Reboot.

Please understand this mechanism.

Thanks

This is Ultima4 boot disk for MB4c board.

I patch it for Mockingboard 4c on APPLE //c.

I made this patched image disk and you can select mockingboard on //c.

You only need 1st booting disk for this and other disk images you could find here in https://www.apple.asimov.net/

Thanks.

Dear friends,

This is the final mockingboard 4c.

* Mockingboard 4c doesn't include the 65C02 CPU.

it is a setup photo.

It added Volume control line so, you can also control internal speaker volume by APPLE //c volume knob.

I connected AUX to earphone socket for external speaker.

Now, I'm making it for Koreans friends some board already shipped from last Friday.

Please wait for a few weeks for international sale.

Thanks

Ian Kim

* PS

Please refer this link.

He just installed the Mockingboard 4c in his APPLE //c Model #4100.

Sorry for Korean but hope you find some fun.

Thank you~!

Testing volume control by APPLE //c.

If you see the under of APPLE //c, you can finda dial for Volume control.

I decided to use it to for control sound volume for mockingboard 4c too.

And it is working.

It is simple idea but, was complicated to apply at least for me.

with the only +5V single voltage, it isn't easy to apply to control amplifier.

But make it to work as I expected.

As you can see from the 2nd photo, it required pull a line from one point of APPLE //c board.

It is required to control sound volume for Mockingboard 4c.

I ordered final PCBs and hope to have good and nice one for all of us.

I got several 10th orders from Korean APPLE //c fans.

We are waiting for final product and want to have happy time with it.

About 4 weeks later, I could put final prodcuts on eBay for international apple II fans .

If you like it and want to make your apple //c with good sound.

It would be a great chance to grab it.

I'm very proud of this mockingboard compatible sound card for the APPLE //c.

Thank you very much;

Ian Kim

The APPLE //c has no expandable slot and it has no support by sound card such as Mockingboard.

So, If you play some game on //c, It would be some disadvantage compare to APPLE //e with mockingboard.

Due to this lack of this capability, I tried to build mockingboard compatible sound card and completed designed.

Now, It works very well as the Mockingboard A/C(no voice chip).

It was required accurate timing control and firmware conflict evasion techniques.

APPLE //c doesn't have I/O slot and I needed to make required signals.

For this, I used CPU socket for it.

This sound card can be used on APPLE Iic 4000and 4100 all models.(Not //c plus nor Laser128)

Tested more than several days and no any issued encountered.

I prepared a AUX sound connector for external speaker.

And two small speaker provided for pre-order users.

Anyway, I'm receiving pre-orders from the Korean APPLE II enthusiast,

About a month later, I will put some on eBay for international APPLE II enthusiast,

If you have this device on your APPLE //c,  Your APPLE//c would be almost complete sets.

Dear all,

I made PCB and set on my APPLE IIc.

But, there are some debugging points and now It is working now.

I put two small speaker inside of APPLE IIc. looks good.

I'm trying to control the Sound volume as followed APPLE IIc one. but, it's harder than I expected.

I failed to make good control so, I'm not sure can put this function on the board.

Thanks

Ian Kim
