tdididit #4 Posted April 17, 2016 (edited) Battery hold real time clock for fat32 timestamps. HSC data can be dumped & reloaded from SD cart Wysłane z mojego X2_Twin przy użyciu Tapatalka Edited April 17, 2016 by tdididit Quote Share this post Link to post Share on other sites

tdididit #6 Posted April 17, 2016 You know better than me....sure.... I just mentioned HSC memory regions can be used many ways Wysłane z mojego X2_Twin przy użyciu Tapatalka Quote Share this post Link to post Share on other sites
gambler172 #7 Posted April 18, 2016 It will also have keyboard access and plays all XM games. And it will have a surprise option 2 Quote Share this post Link to post Share on other sites
tep392 #8 Posted April 18, 2016 Is this CPUWIZ's handywork? Quote Share this post Link to post Share on other sites
tdididit #9 Posted April 18, 2016 (edited) Is this CPUWIZ's handywork? this time it is my work mid stage prototype but XM & homebrew games work smooth on it yesterday Gambler172 was testing it, I think he can tell bit more about "user feelings" I can share only some technical details if you like -ps- Tower Toppler works.There was no glue logic issue, only "difficult switch" setting Edited April 18, 2016 by tdididit Quote Share this post Link to post Share on other sites
tdididit #11 Posted April 18, 2016 tmm.png sadly, there was only two prototypes of 256kB ram carts - both are now in hands of AA members a78-flashcarts are sold too, you will need to wait for next batch when all hidden bugs in firmware will be fixed Quote Share this post Link to post Share on other sites
gambler172 #12 Posted April 18, 2016 (edited) Is this CPUWIZ's handywork?no ☺I checked it out yesterday......you will need an arduino.. but this is not too expensive....Works great for a proto. Games must be put on SD card as a78 files....This baby is easy to handle.... a must for every 7800 fan. greetings Walter Edited April 18, 2016 by gambler172 Quote Share this post Link to post Share on other sites
Shawn #13 Posted April 19, 2016 How do you flash the cartridge? Also how does the dongle interact with the cart (if it does, I'm at a loss right now, could just be cause I'm really tired and lack of sleep making me dumb). Quote Share this post Link to post Share on other sites
Jinks #14 Posted April 19, 2016 Very cool! I am interested. Quote Share this post Link to post Share on other sites
+frankodragon #15 Posted April 19, 2016 Is 256K the limit or are you working on a 512K? You know what I'm talking about (hint,hint) Quote Share this post Link to post Share on other sites
tdididit #16 Posted April 19, 2016 How do you flash the cartridge? Also how does the dongle interact with the cart (if it does, I'm at a loss right now, could just be cause I'm really tired and lack of sleep making me dumb). Proto cart is a 256kB RAM expansion. Cart firmware is communicate with peripheral device over second controller port (SD/RTC/Keyboard) you can load a78 image files from SD card using one of applications included in firmware Quote Share this post Link to post Share on other sites
tdididit #17 Posted April 19, 2016 Is 256K the limit or are you working on a 512K? You know what I'm talking about (hint,hint) Proto got only 256kB of RAM. a78-flashcart & a78-flashcart+ are bit more advanced. Developer version have 512kB RAM compatible with XBoard & 512kB in-system programmable Flash ROM I will write bit more about them in next two weeks when first batch will be assembled and shipped to the users.

tdididit #18 Posted April 19, 2016 (edited) Very cool! I am interested. What happend? Let me remind you ... ... it is same project Edited April 19, 2016 by tdididit Quote Share this post Link to post Share on other sites
+grips03 #19 Posted April 19, 2016 Is this a 7800 flash cart, i.e. load many roms on SD card, and then select rom to load from menu after 7800 boots? Quote Share this post Link to post Share on other sites
Jinks #20 Posted April 19, 2016 What happend? Let me remind you ... jinks-answer.png ... it is same project Ok sorry. If I offended you I apologize. I really don't remember. Quote Share this post Link to post Share on other sites
78001987 #21 Posted April 19, 2016 How do you flash the cartridge? Also how does the dongle interact with the cart (if it does, I'm at a loss right now, could just be cause I'm really tired and lack of sleep making me dumb). it looks like you plug the cart into the dongle, and the dongle plugs into the PC via USB, kinda like an external hard drive or SD Card reader Quote Share this post Link to post Share on other sites
tdididit #22 Posted April 19, 2016 Is this a 7800 flash cart, i.e. load many roms on SD card, and then select rom to load from menu after 7800 boots? Yes, it is main feature of this prototype. New comming designs will have bit more features and tools 1 Quote Share this post Link to post Share on other sites
tdididit #23 Posted April 19, 2016 (edited) it looks like you plug the cart into the dongle, and the dongle plugs into the PC via USB, kinda like an external hard drive or SD Card reader USB-B plug is only for powering and updating Arduino code. top USB-A plug is for keyboard. Device is connected to A7800 via second joy port Edited April 19, 2016 by tdididit Quote Share this post Link to post Share on other sites
78001987 #24 Posted April 19, 2016 USB-B plug is only for powering and updating Arduino code. top USB-A plug is for keyboard. Device is connected to A7800 via second joy port so how do you flash ROMs to it? Quote Share this post Link to post Share on other sites
tdididit #25 Posted April 19, 2016 (edited) so how do you flash ROMs to it? ROMS are loaded not flashed, from fat32 SD card plugged into Arduino Shield - this shield is connected to Atari joystick port JOY2SD now evolved into simple-EPI device. a78-simpleXM cart will be all-in-one device with SD/USB host controller (keyboard/mouse/usb storage) on cartridge pcb, but I will be able to show XM cart after alpha stage I am publishing my work in github repositories https://github.com/tdididit?tab=repositories Edited April 19, 2016 by tdididit 3 Quote Share this post Link to post Share on other sites
