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

For long time, I used this PS2 Keyboard adapter for my APPLE //e and there was no inconvenices.


And  Yesterday, I obtain a MINI keyboard adapter.
It is quite simple and looks good for small table for testing.


It worked with this PS2 adapter but, I found a issue.

PS2 Keybaord adapter was developed for full sized keyboard and there is 10keys pad is on right side.
And adapter always the Num lock ON. it was OK with it. 
but for this mini keyboard is using this 10keys are overlayed over the alphabet area. It became a problem here.
I can't key-in properly cause the num lock always ON and it send numbers insted alphabet..

 

'PS2 Keyboard Adapter didn't be designed to OFF the Num lock.'

I started to update firmware to handle Num Lock and now, I can OFF and ON.
And It can save as Power Default.
So, now It can ON or OFF Num lock when Power ON.

And Bonus function, Also Caps Lock also can save for Power ON default.

Unfortunatelly, This firmware coudn't be updated by remote so, only future ordered items would be apply this function. sorry for this.

If user could send the board to me, I could update firmware for free but, shipping costs is the matter.

Thanks
Ian Kim

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

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.

Ian Kim


Features

UART Serial IN/OUT support(115200,8b,1s,No patiry)

User can use a serial device(UART TTL) as another Keyboard.

I've tested in on the Tera term and made it even support F5-F9 Macro keys.(Saving macro is Shift F5, Recall is just F5)

Also support Arrows(Up, Down, Left, Right) Hence, You can even playable games via the Serial connection.

Also tested Bluetooth dongle, Works well but, There is no CTRL and Arrow Keys on the Blueterm.

I hope someone make a good Keyboard APP and we can use it as wireless keyboard for fun. :)

(5V TTL singla Level), If you want another Speed, Please let me know your request before to ship it.

Macro key support; 

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

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

Ian Kim

Some of people want a keyboard adapter for APPLE //e.

So, I made PCB and testing the function.


I designed it as small size and simple not complicated one.

Simple to use as

Just plug your PS2 keyboard and insert on keyboard socket of the APPLE //e.

This is my concept for this adapter board.



It works but there are still some of points to enhance.

After complete it, you can see it on eBay too.


I also have plan to make adapter for APPLE //c.

My one of APPLE //c had bad keyboard and I want to use a PS2 keyboard instead of it. and attach a PS2 socket on the //c case. so, simply plug in any PS2 keyboard and can use APPLE //c.

Isn't it good idea? :)


Thanks anyway,

Ian

PS2 keyboard adaptor for APPLE II and II+

 

INTRODUCTION

It is a PS2 keyboard  adaptor for APPLE][ and ][+ system.

If your system doens't have good keyboard or hard to maintain it,

if would be good choice to use your APPLE2 without inconviniences.

It is  morethan just keyboard adaptor and have several useful functions. 

 

 

Macro key

You can assign Function keys to macro key. it would be very useful to make own program of keyin on your APPLE2

it can hold maximum 40 letters for each Function key(F1~F12 except F3)

Assigned macro data will keep even if Powered off.

But, F3 key is recall key, which is hold last line and hold maximum 255 letters and not permanent data stored.

 

Capital and small letter support

Ofcause, your APPLE2 must have small letter fonts on the system.

And Shift + key is always Capital letter.

 

Serial Intput data to APPLE2 as key in

it has a serial input pin and Serial data will redirect to APPLE2 keyboard.

It may use some sort of data tranfer or remote key typing such as even wireless keyboard.

(Speed: 9600bps  TTL Level)

 

 

English User's manual :

PS2 adapter for APPLEII.pdf

 

 

Out of stock


New version of board will be announce soon.


I designed new PCB for less costs and easy make.

It provided the UART connection but, I didn't receive any comments or feedback from user.

I guess that user don't use it.

I removed in this version and it focused only the BASIC and important Keyboard interface role for APPLE ][+.


Board looks better and easy to make it.

The price slight cheaper and It would be good for APPLE ][+ users who doesn't have good Keyboard due to the age.


I will announce when it ready for sale.

Thank you 

Ian Kim
