Re: MiSTer updates and changelog

CoCo3 update 20240318: 1. Changed PIA 2 addressing to align with real CoCo3 hardware and end at FF2F. 2. Re-arranged MiSTer drive LUNs to support future auto-boot from SDC drive 0. 3. Added 'Auto Run' feature. You must use slot 2 [SDC]. Take your floppy or HD and copy it to a file name of 'boot.vhd'. This will be auto mounted to drive 0 on the SDC....

Re: Coco3 Core Released

Just a FYI..... This text is specific to the problem specified earlier with some OS9 builds which boot into semi-graphics mode. Presented here is why and a temp solution. A better solution is in the works. The MiSTer CoCo3 project is a port of CoCo3FPGA for the DE1 board by Gary Becker. This is from the documentation: The only Semi-graphics (SG) mo...

Re: Auto Mount File on Boot?

I'm answering this as it was answered on Discord... <Discord User> there's two ways. You can use persistent file selection, or you can use boot.vhd. FC is the option for persistent selection [in the Menu] <ME> How do you address the boot.vhd option? I am familiar with the rom loading mech but I need random access and not a loading of a rom. <Discor...

Auto Mount File on Boot?

I'm pretty familiar with MiSTer file operations through the virtual SD interface. I have it working well in my core. My question is: Is there any way to auto mount a file on boot? I would like to put a filename in the Mister.ini unique to my core which is passed to my core, mounted and assigned to a pre-defined unit number. Presently, I see no way ...

Re: Coco3 Core Released

The coco3 core does not need more than 32M, however, since the core handles the sdram controller internally, the core would have to understand and make both modules work. I have 128MB and the SDRAM code I used was tailored around that. I do not have a 32M module at present and fixing this will likely be low on the fix list. I am aware that a proble...

Hi folks,
I just added a note to the readme.md file for the next release:
Note: This core requires the external sdram memory module to function.

Other changes in process...

Re: CoCo 3 core updates? Docs? Anything?

I have also been in discussions with alanswx. He is close to booting the same core. Yes [I will double confirm this with Gary but his source code is free now - its just a bit hard to find. I think between alanswx me we will get it working.

Re: CoCo 3 core updates? Docs? Anything?

I realize this is a old thread. I am trying to understand the history here for a COCO3 port. I am in discussions with Gary Becker on porting his COCO3 design to MiSTer. I previously did the port to the DE2-115 board. Who is the owner of the port referenced earlier in this thread who had issue? Gary's port is not of the Dragon - it is a true COCO3. ...
