C16 and Plus 4 on the Mist

Hi,

a brilliant member of the Mist-fpga.net forum has implemented the TED chip in verilog.

He is now working on Mist ports of the C16 and Plus4 Commodore computers

Great job!

Just to give the right credit where it's due.

The TED chip was ported to verilog by an uguarian developer:

The Mist port is under development by members of the Mist-fpga.net forum

Wow much love! ..

Hopefully they can also implement the serial IO pins on the mist midi (like the Amiga and Atari ST cores) so you can use TCPSER (say on a raspberry Pi) and "dial up" old school bbs over the net!

Looking forward to seeing this. My friend had a C16, and the only game I remember was called The Exploits Of Fingers Malone, a platform game where I'm pretty sure your character was a suitcase with big eyes!

That is excellent news. Kikstart is a must play on C16!

Kickstart works nicely and so does Fingers Malone using the latest core posted in

Great, I'll try that soon!

I have released a first version on github.

Thanks a lot!!

I'll try as soon as I can (i.e. this weekend).

Is the source on github MiST compatible or is it for the Papilio module as per the readme.txt?

Just curious as id like to take a stab at playing with it to learn how to do MiST cores..

Thanks!

Great work, MasterOfGizmo!

I tried it out with Jet Set Willy and it works flawlessly.

Can I be cheeky and ask for SID support?

That's it, all I need is a Dragon 32 core and I'll have every proper computer I ever owned right in one little grey box

Thought it was time I stopped lurking. Excellent work as usual

64k games seem to work fine

, only issue at that point is with only .prg support at the moment games such may be missing disk functionality.

A full power off seems to be required to load a new .prg but apart from the above I haven't noticed any issues

An example of this mornings testing

It's the source of the mist port. I should indeed add a few mist related lines to the readme.

I really only did the minor work of porting this to the mist. 99% of your gratitude belong to the original author. Please consider dropping him a small thank you note if you enjoy this core. Since his original work required some special hardware you are likely among his very first users.

Next on the agenda is the ability to switch between 16k and 64k. And then there's of course the floppy support. I already spent a few hours on that before I realized that prg injection would be much easier and already pretty useful. Adding the 1541 from the c64 core is very likely possible but will push the core very close to the FPGAs internal memory limits as we need space for c16 ROM as well as the ROM and RAM of the 1541. The c64 was easier as it has less ROM.

Would a possiblity be to move Roms on to a user directory on the SD-Card?

I am going to assume you/he is using the C16 rom image and not the one from the plus/4 which has the less than spectacular "built-in" programs that even back when the Plus/4 was new were considered underwhelming and outdated (only actual one of any use was the built in machine language monitor).. (I haven't looked at the core yet to know which is being used) but if its the P+4 im sure those app-roms could be omitted.

Overall this is fantastic news .. and I am excited to give this core a good workout .. thanks for your help in porting it!

The latest version now includes the 1541 we have already used in the c64 core.

A quick test allowed me to run majesty of sprites.

What the fudge?! That was fast. Awesome work, man! I will download tonight and try it out.

Nice!..

is it just me or is the border color the wrong shade of purple for the c16 core? I'd need to compare it with my actual plus/4 I have but im pretty sure the core has a border thats a hair too blue.. that said I might need to check my VGA monitor color settings. Just curious if anyone else noticed that minor quirk?

Here is what I recall it to actually look like
