The layout is there also, on OSHW page go right on PCB display, 2/2 is v1.1.

Updated ROM for Canyon Escape is here. Corrected one bug slowing down the game in some conditions and added the covered distance in Game Over screen. CanyonEscape.rom

@nanochess Thank you

Is there any way to update my submission, I’ve found a bug slowing down the game in some conditions? I’ve also added the distance covered in game over screen.

Name: Canyon Escape Description: You need to escape from you evil enemies travelling through a narrow canyon Instructions: Press any key to start the game Controls during gameplay: Directions to move UP, DOWN, LEFT and RIGHT LEFT/RIGHT BUTTON to fire left/right rocket Avoid or destroy rocks Collect Fuel, current tank level is shown on top right of screen, running out of fuel will cost you one life Additional life bonus appears fom time to time Especially avoid enemy rockets fired from top of screen Your score will be displayed if you reach end of the canyon, score is based on remaning lifes, fuel, collected lifes and fuel as well as number of destroyed rocks CanyonEscape.rom Enjoy!

I confirm that my others SECAM INTV which are modified PAL versions are also running on a 4MHz crystal (I can't post pictures at the moment but I took some and will later) I've also installed the development environement and compiled PiRTO firmware succesfully. I've then added additional NOPs and saw some improvements, splash screen and directory listing are displayed but entering a directory isn't working and starting games either. What is weird and might be a hint, is that the highlighted directory and/or file goes down till the latest one on screen, like if the ddown direction on controller was pressed. I've started with 208 NOPs for delWR and 162 for delRD. Playing with these numbers generates some changes but I couldn't get it working. Is there something I can measure with an oscilloscope to determine the numbers rather than guessing?

About the displayed files it was my mistake, I had .int files mixed with .bin files, a batch rename solved the issue. Now about the SECAM version I will need to find time to install the pico development suite and learn about it. I anyhow wanted to look into this so it gives me another reason to start Here is a picture from the SECAM version motherboard and a close up of the quartz at 4MHz:

I’ve received new 74LVC245 chips that are working now. I confirm that the device is working with SECAM Intellivisions that are modified PAL versions but NOT with true SECAM versions (serial number starting with RH). I still have an issue, on my quickly prepared card only few titles are visible in the list, I’ve split the titles by letters in subfolders and even when keeping the names short not all are appearing. I’ll test more later.

I'm preparing something to participate this time

It seems that I have the same issue with 74LVC245 bought from Aliexpress, I managed to launch some games after several trials using the NTSC firmware on a PAL(SECAM) Intellivision. Regarding SECAM Intellivisions, it exists 2 variants, the first one (usually PN start with P2 or P3) are modified PAL versions, the piRTO should work on those. The other variant (PN starts with RH) is a native SECAM variant, once my piRTO will work I'll check how it works on those, however I do not believe the clock is different at PAL and SECAM share the same frequencies, only the color encoding (chroma) is done differently.

I had some slight progress those last days, if everything goes lmike planned I shoudl have 5 or 6 Apple 2c adapters ready by end of the week. I'll contact the people on waiting list once some adapters will be completed.

I confirm that I making some new Apple 2c RGB adapters, I will a few left after the current list of interested people will be served.

Génial, il faut que je test ça très vite! Merci

That's perfect for me! Thank you

That is the main reason for me to ask for schematics, to be able to do a project we can order on JLCPCB with assembled SMD components. Only Pico would remain to be soldered.

Thanks a lot for this, would you mind to share the schematic also? One other thing, it is not clear to me what you meant with this sentence: “Assembly notes: Use only 74lvc245 IC, not LVC ones are not 3,3 tolerant and may damage your Pico.” Great job in any case!

Nice, waiting to be able to test this one.

I wanted to let you know where I ended up. Replacing STK7308 and other components that I've found broken didn't solve the issue, I even managed to break the new components. I, for some time, used a new meanwell power supply to provide +5V and +12V directly to the power board, by passing the high voltage stage and it worked without any issue (+24V is only required for the additional printer that I do not have) I finally found a broken PCW8256, missing the cpu board and keyboard, for cheap and transplanted its analog board, now I have a fully functional PCW8512.

I've got soem requests to make a new batch of Apple 2c RGB adapters (A2cRGB), if I get enough interest (15 parts) I will do another small batch. Please express your interest here. Apple 2e boards are still available.

Hi, I've sent you several private messages, if I do not get any answer soon I will transfer the adapter I've kept for you to someone else. This is the last one I have and might not do more. Best regards

@mike351 Standard shipping to Autralia is 15€, the next option is 30€ with increased tracking and insurance. Which version are you looking for the one for Apple 2c or for Apple 2e? It makes no difference for the shipping costs, the weight is similar. We should switch to PM for the next steps

Only RGB output is available. I have a small number of PCBs left for the 2c version for the 2e I still have around 10.

Hi, Yes this monitor is clearly not compatible with standard output from an Apple 2 that is 15kHz. The RGB adapter doesn't modify the frequencies and the monitor must still be able to display standard NTSC (or PAL) frequencies : 15kHz horizontal and 60Hz vertical (50Hz for PAL). Regarding building up cards from teh EasyEDA project, the easiest is to create an account and order from JLCPCB. You can also order from any other supplier by generating the gerber files from EasyEDA (file/export/gerber from menu). The gerber should be compatible with any online company expectations. I have some populated PCB left (all surface mounted component in place) Bare PCBs are also available from here https://www.vikingdigital.com/product/apple-iic-to-rgb-rgbs-video-adapter-a2crgb/ For fully mounted part I will need to build it and I will not be able to in the next 2 weeks. This one is looking like this, and is 40€ + shipping: I'm from Europe, shipping to US can be expensive

@offby-wan I've sent you a PM

Hi, Yes I still have some adapters, I’ll contact you by PM.
