공지사항

My APPLE IIc doesn't have good sound as //e. I can't use mocking board nor any other sound card for APPLE IIc.

For long time, I though if I could make a device for APPLE IIc. I will try for sound card for APPLE IIc.

Now, I started for it.

I built a simple board for APPLE IIc.

It have to insert on the position of CPU and taking all required signal from there.






And I used a CPLD to control lines for CPU and other chips(Sound chips and PIA).

CPU connected as transparent to the system and I could masking the C4xx for mocking boar slot.


First time, I got bus conflict as this.

But, successfully removed this error. anyway motherboard doesn't damaged with this impact.


Only C4xx area masked. so, mouse firmware is not there but, I can make it back as normal.


I have more wiring and need idea to take required signals without technical issue.

Also there is IRQ issue, it isn't the same as //e andmore there is no external example of IRQ on APPLE IIc.


Hope to complete this project soon.


Thanks

Ian Kim
