Adam Computer (Coleco) by AlanSWX Working !!!

[ron]

From AlanSWX ,the Coleco Adam Computer core is going to land very soon in your MiSTer.
I do not know when is going to be released but seems to be really close.

The core is almost ready, just a little issue loading Adam roms pendant to solve. CP/M loads like a charm. DISK and Digital Data Packs (DDP) works fine, most of software loads fine from both media.

Another Holy Grail that we can enjoy thanks to AlanSWX, congratulations. Stay Tuned !!!
Great Job !!!

Released!!!

I know that it doesn't load the Adam cartridges, and there is some spurious keypress thing the first time. Otherwise it is fairly complete.

I always wanted to play around with one of these. ColecoVison is still my favorite of the pre-nes consoles. I wonder how a modern keyboard will translate for use.

Adam is the good guy...Eve ate the Apple IIe

marketing is weird

Another fascinating system added to the MiSTer museum! They used to have one for sale at the local toy store. I was fascinated by it at the time. Really cool to be able to use it on my MiSTer.

Is it emulated accurately enough that if you don't turn the printer on it won't work? <G>

The power supply for the computer was in the printer.. so strange. I do want to add printer emulation to all these old cores.. We need print shop banners.

One thing that isn't accurately emulated, which I think should be added for nostalgia sake, is that upon power up, it should pick the last tape you mounted and wipe a portion of it.

Is it just me, or is the "Home" key not working? It's super important for running SmartLogo...

I've been testing Donkey Kong on all the platforms I can recently, and I came across a probable issue with this core.
It's hard for me to track down exactly what's wrong with it, but the result is that it makes the 2nd section (of the 2nd level) the one with the elevators and the bouncing Jack effectively impossible to beat. It appears that the spring/Jack movement or hit detection is happening too quickly. The only other thing that may indicate where the problem lies is that the 2 loading screens "Adam" and "Donkey Kong" go by far too quickly, which may indicate that the speed of the 'cpu' is too fast?

Based on video footage of a true Coleco Adam playing the game, it appears Mario's speed is relatively the same, but when I see people play through that section it does appear there's a much bigger grace period for the gap to get to the top of the final ladder on that level, which makes me think that the Jack is based on cpu speed but Mario's input > Movement cycle may be dependent on another factor?

Would love to know if anyone else is having this issue.
