이안은 뭐하니?

Also Tested CPM 3.0 works!

With several Logic update on CPLD, I got finally working softcard.

I tested it and work as 1Mhz and 2Mhz.

My target is 7Mhz Z80 card. it would be very interesting steps.

The softcard used DMA and RDY and Z80 Wait for it's purpose of CPU.

Thanks MS for the idea of Z80 working on 6502 based Computer.

Now, I'm starting to put TMS9918 VDP and trying to make it work.

I hope to show some of working screen soon.

Thanks

APPLE II using 6502 CPU and there are another 8 bits CPU Z80 is one of famous one too.

In fact, APPLE II can use both of CPU Z80 and 6502 but, It was almost forgotten technology how to applied it on APPLE II.

Hence, I started to make Z80 card and it will work as a softcard for CP/M.

Used Z80 CPU and some chips.

Major control chip will use a CPLD to act as Softcard and started wiring.

Wiring always hard job but, but have to check all of lines to make sure to avoid mistake connection.

I was took long hours and needed adjust wires to fix my mistakes.

I set chips and added some more wiring for proper emulate the Softcard.

I did research about the softcard and could learn about the DMA works and RDY and the trick of timing for Z80 CPU.

My plan is several steps,

First, I want make it run the CP/M OS.

For this I will apply some slow Mhz and try to make it run as Softcard.

I think that it is possible to make it run 1Mhz and it would be easier than other faster speed.

Then Try other faster speed.

2Mhz is original softcard and at least have to reach this speed to make feel same as what I experienced by the CP/M by softcard.

The final softcard make it run as 7Mhz..

It is the maximum possibility with softcard design I guess.

Anyway, there is a reference of 7Mhz CP/M.

It looks very interesting to me. but, I don't understand fully about the tricks.

Anyway, Let me see if it works.

Thanks

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 patched it and running on //c.

NSCT.nib

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

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

Thank you.

PS2 keyboard adapter for APPLE II and II+

INTRODUCTION

It is the improved second version of PS2 adapter for APPLE ][ and ][ plus.

It support LED indicator on PS2 keyboard and improved Keyboard key 

detecting method.

You can use PS2 Keyboard on your APPLE ][ and ][+.

It is more than just an adapter. I prepared some useful functions for you.

FEATURES

Support LED on your Keyboard

PS2 keyboard have 3 LED indicator and this PS2 adapter using it for indicator for

Numlock and Caps lock. It will ON/OFF as followed Keyboard status.

Support Macro key

You can assign your key array on each function key.

For example, You can put ‘CATALOG’ command in F1 and when you need it, 

Just press F1 then It will key-in ‘CATALOG’ for you. 

This function prepared F1,F2 and F4 to F12

All assigned macro data store into EEPROM  

If you want re type the last line. F3 is the key for Recall the last line.

It can hold maximum 40 letters.

F3 recall can hold up to 255 letters and not store into EEPROM.

Lower and upper case support

If your APPLE II support Lower case, The Caps lock key will work for you.

Your APPLE II must have support lowercase fonts.

Shift +(letter) is always Capital letter.

Number key pads

Your number keypad is always working so indicate the NumLock LED ON.

Arrow keys

Upper and Lower Arrow key is support same as the APPLE //e.

Backspace is remapped to <- (Left arrow).

CTRL+Reset

It assigned to CTRL + BREAK and CTRL+ Scroll Lock.

Auto repeat

Simply keep press..

Help Message

Press 'Alt+ESC' then It will key-in the Help message. Please do it on APPLE Prompt ']'

Thank you very much.

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

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.
