I have just started using the Emma 02 Emulator.
I am interested in the Membership Card.
I have studied the documentation on it.
Settings
Elf
Membership Card
Monitor_8000.bin
IO: N2
Check Boot: 8000
Check Front Panel
Memory: 32 KB RAM - 32 KB ROM
---
The VT 100 terminal works.
The front panel load function dose not seam to work. I think there is a bug in the emulator.
I would like to see a video that shows it working.

Hi John,

Thanks for your feedback/bug report, sorry for the slow reply; I'm on business in Croatia so didn't have time to look into this until today.
I think it might work if you 'unselect' the 'Auto boot' checkbox. Could you try that? for me that worked.

Possibly the reason is that if you use autoboot the CPU will start-up at 0x8000 and as such set R0 to a value of 0x8000 counting up until a SEP Rx is done. When you then switch to load mode the input will be done on an address larger than 0x8000 where you have the monitor ROM which won't work. A real membership card would not do an autoboot either.

Let me know if that helped or not.

I'm planning to release a new version later this month, so if I need to do any bug fix I will try to include that. Note I used a pre-release so possibly that is slightly different from your version. Feel free to drop me an email directly so I can provide a link to the pre-release.

Cheers, Marcel.

Settings:
Menu=>Settings=>CPU Type=>CDP1802
uncheck Boot: 8000h
I continue to have trouble getting Front Panel DMA to work. Perhaps I am doing something wrong.
