이안은 뭐하니?

Do you have a keyboard problem on your APPLE //c?

If yes, It would be a good alternative device for you.

You can use PS2 keyboard on your APPLE //c.

Features

Macro key support ; 

F1,F2,(F3 is recall key) and F4~F12 up to 250 Chars.

Macro key data store into nonvolatile EEPROM.

Dual keyboard support; 

User can put original APPLE //c keyboard and PS2 keyboard at the same time and works both.

<- Back space;  Mapped to <-(Left arrow), you can use it similar as Back space.

Number key pad; Always ON and works

Control Reset; Assign to Ctrl + Break or Ctrl + Scroll Lock

Open Apple; Left Window

Solid Apple; Right Window

HELP; Press 'Alt+ESC' then It will key-in the Help messages (Please do it on ']' prompt)

LED indicator; You can LED status of the keyboard as followed the Caps lock.

TTL Serial connection support;

TTL UART isn't very good to use the APPLE //c.

Just for fun you can use the APPLE //c or control //c via the Wireless connection and/or bluetooth connection.

I've tested the Bluetooth connection and works even can play game.

But, if you can't find any good PS2 keyboard or just want to use remote keyboard via the UART connection, It would be wonderful method for you.

I spend some hours to support it for you.

it isn't the same as PS2 keyboard hence, you have to know some more to use full way.

You can send key data to APPLE //c via the UART (115200 fixed BAUD rates)

If you connect it by serial terminal (The Tera term recommended), But, still you can use PS2 keyboard and/or APPLE //c own keyboard.

Most of all APPLE //c key are mapped except OPEN APPLE and CLOSED APPLE.

I tested all under the Tera term

Support All Arrow keys. You can play game via the Serial connection.

Support F5,F6,F7,F8 saving and recall macro support (Shift + Fn; Saving to Macro, Fn; recall macro)

Support F3; last line recall

Ctrl + Reset -> F12 ; I can't apply it to any other key. Just press F12 then APPLE //c will got Ctrl+Reset.

Tested it on the APPLE //c (Model#A2S4000 and A2S4100) not test on APPLE //c plus yet.

User's Manual

PS2 adapter for APPLE IIc(Manual).pdf

If you have any concern or idea, please email me.

I will try to apply your idea.

** The PS2 socket will not be soldered on the board. I will leave it blank and OFF.

This is very useful PS2 Adapter for APPLE //e series.

I like to use PS2 keyboard cause It is conveniences,cheaper, good to maintain.

And my APPLE //e has some times double key-in.

This inconveniences made me to develop this Keyboard adapter.

This adapter will help you to use APPLE //e without any Keyboard problem.

This adapter have interesting features, it designed to help users who like to key in and like to make program still now.

The Serial connection, It will help you to transfer Srouce code via the TTL serial connection to APPLE //e.

and It would be very useful to transfer way of source code without other DISK or serial device.

I hope someone use it wisely and have happy time with the APPLE //e again.

Even remote key-in works if you connect it via the wireless dongle.

Thank you very much.

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~!

Dear friends,

Today is 1st Jan on lunar calendar,

In Korea, we also celebrate Lunar new year!

Anyway, This year sojak sign is Red monkey.

I finished this design for APPLE //e.

Firmware task was done and works very well.

I added some important function for user conveniences.

1) You can save your key code as Macro.

You can assign your key data into F1~F12 (except F3. it used recall it means, it will retype what you typed before until Return)

2) You can also plug in your APPLE //e keyboard, It means you can still use your original APPLE //e keyboard at the same time and you can use PS2 keyboard together.

3) As you can see the photo, there is PS2 AUX pins prepared. You can use it to connect your own PS2 socket  to set your favorite position on APPLE //e (DIY project).

When I finished new PCB, I will put on eBay.

Please wait for this new conveniences device for your APPLE //e.

Thanks;

Ian

**ADDED**

This keyboard adapter can use with your own keyboard and PS2 keyboard at the same time.

It is really nice but, I found some inconveniences.

if you keyin on APPLE //e keyboard with capslocks.

It was influence to PS2. so, it will typed only upper case. if you pushed the capslock on APPLE //e.

it followed original keyboard capslocks switch position.

But, I did seperated it.

Now, it following your keyboard.

For example,

If you key in lower case on APPLE //e keyboard. you can type lower case in there

but, if you set capslock on PS2 keyboard, it will work as you caplocks on PS2 keyboard.

even you ushed the capslocks on PS2 it would influence to APPLE //e keyboard.

This function is seperated not merged or influenced to other keyboard each other.

it is simple method but, it was complicate to work properly.

it looks good to me and I'm sure you also like it.

Now, I can order to make completed board.

I hope you like it.

** ADDED on 8th Feb.

There are different Keyboard chip for APPLE //e and //c.

My tested keyboard controller chip is AY-5-3600 and works great there.

But, I found another chip which was used //e platinum and //c 4100 model.

and this model used KR9600 PRO chip.

and found failed work on it.

I checked the reason why and there is negative control signal for key press detection.

I though i finished all for all APPLE //e.. but, there is important different between AY-5-3600 with KR9600 chip.

I started researching again for it.

Why this incompatible issue happened? 

APPLE used different keyboard controller due to some unopened issue. 

I'm not sure now, but, I guess there may happened signal overload when user press several keys at the same time.

I'm researching it but, I can't make it run properly. some key works with double pressing keys.. not perfectly work to use.

And now, my keyboard adapter works on AY-5-3600 chip but not for KR9600 keyboard controller.

I will announce again if I done to apply for all of //e.

** ADDED on 18th Feb.

I ordered PCB and it will be good for some of APPLE //e.

I will also keep try to support the KR9600 keyboard decoder chip but, I still didn't find good way to make it perfect.

It may need another H/W design to make it compatible for all type of APPLE //e.

Anyway, It would be a great choice to replace present keyboard who doesn't have good keyboard which APPLE //e used the KR3600 chip.

Here is some of major function of this PS2 Keyboard adapter.

1) Your can still use the present APPLE //e Keyboard at the same time.

2) Enhanced ASM programming, I used Assembly codes for accurate Keyboard Emulation.

3) Superb Macro memory support (Hold up to 250 letters)

** ADDED on 8th Mar.

It support all of decoder chip on your APPLE //e now and more Serial connection was improved much.

I will announce when it ready for sale. maybe need a weeks later.

Thanks
