BadApple,car: my cardridge works (b014)

it's been a while since i've released an update so here's at least something, beta of 0014

no major changes except for some ATR improvements and search capability

-- ATR

- OS.XEX was renamed to OSXEX so be sure to copy it from the update zip file (old one won't work since there were changes)
- ATR files are now writable (i strongly recommend having a backup of your SD card content just in case)
- you can now map multiple ATR files (using TAB) to D1:-D4: and use right cart button to cycle them
- OPTION key functionality is inverted (so BASIC is off by default)

-- search

- use / to search for files (recursively down from the current dir)
- ESC to cancel search
- BACKSPACE to return to normal file listing

this beta was not intensively tested so please report any issues

download a014



- searching: empty directory = suspension of the operation atari (exactly: cartridge suspended)
- removing the SD card from the slot = suspension of the operation atari (exactly: cartridge suspended)

- updating firmware (shift+option+U): before click start - you can not cancel

i just had to build an unbricker to send out because one cart was bricked during update yesterday (user error if i understand it right), chances of bricking should be minimal if you follow the instructions but just in case, if you have basic soldering skills (solder 5 wires to pcb), you can order these two items (should be under $4 shipped) and build one instead of buying xilinx platform cable (which is quite expensive) or shipping the cart back to me for unbricking (which is probably also not cheap especially from USA)

https://www.aliexpre...2787305004.html(6P version)

i'll provide the instructions and what to flash to esp8266 (via usb) so it can act as unbricker (it will configure fpga so the update procedure can be ran again and flash chip reprogrammed)



TMP: thank you for help


instruction, if the cartridge was interrupted programming

1. remove cart from the shell
2. plug unbricker into the cart
3. plug cart into atari
4. turn on atari
5. plug unbricker into usb (computer or usb charger)
6. wait until it stops blinking
7. press reset on atari

after that, avgcart menu should come up and you should be able to start the update again (unbricker will fix it just temporarily, you need to run the update again to program the flash)

This looks good and it should fit fine on top of the XEL's Pokey as you've shown it. Can you explain more about what external signals are specifically needed for operation? And what is the 12v/5v jumper thing about? Perhaps there is way that I can better support this in the released version of the XEL PCB if I know what you require (i.e, extra header with desired signal connections).


From pokey socket (left or right):  D0-7, A0-1 (maybe A2-3), R/W, Phi2

Outside: +12V power supply AD7226, but you can give 5V (covox plays weaker) - look Candle IOboard  http://spiflash.org/node/8

Adress line from chip select decoding 74HCT138: pin 13 ($D2xx) or pin 7 or 9 ($D6xx / $D7xx)


For address precision you can add line A7 (as ONE) nad A6 (as ZERO) = example as trimming $D280-D2BF

Or another:   A4,A5....  look Evie http://atariki.krap.pl/index.php/Evie


Exit:  Gnd, Left, Right  and mix to Mono.


EDIT: If you are willing to work with me, I was thinking that we could do a trade of one of your working Covox boards for one of the final released versions of the XEL incorporating the changes required to support your board (this would be a bare board with connector kit included).


I've already done Covox extension. But, first: i prefer to test it. I order parts


uCovox was first created. With the help of Candle. Then his experience went to SimpleStereo

Sorry my English is bad.

#3736981 Best MOD player?

Posted by pajero_pn on Sat Apr 8, 2017 2:58 AM

ATR  =  mod file and NEO tracker

For your project (and more) I have a covox add-on. One cable = address selection

Will it be possible? Buy only the motherboard?

Converting Schema: ExpressPCB to KiCAD? Possible?




Ps. for covox player see http://atariage.com/...ayer/?p=3735171

#2464420 Problem with sio2sd firmware 3.1

Posted by pajero_pn on Sun Feb 12, 2012 2:24 AM

The current version of the firmware is 3.1 RC_02 (This is only a test version. This is not the final version !!!)

Bug fix:
- LoaderXEX: fixed, spoiled bits of offset, and he lost $ ad57 bytes
- LoaderXEX: start address of the first block is written to dosable RUNADR and DOSVEC
- LoaderXEX: set $ 9 = 1 and $ 244 = 0

I'm sorry, my English is low
