venom4728a Posted May 3, 2011 Share Posted May 3, 2011 (edited) How do you load the hex file?, will I have to buy a EEprom burner? If so no issues, as I have been thnking about getting one anyways, this will just be the reason to add it to my cart sooner rather then later. I will try to track down all the parts necessary.

yorgle Posted May 4, 2011 Share Posted May 4, 2011 I'll give it a go as well. I want to try some sort of pass through connector so I can leave the keyboard plugged in to the atari. Quote Link to comment Share on other sites More sharing options...
mimo Posted May 4, 2011 Share Posted May 4, 2011 will/could this work with an 800XL keyboard? I have been thinking of building a mini ITX PC in an Atari case, but I am not prepared to sacrifice my one and only 1200xl Quote Link to comment Share on other sites More sharing options...
candle Posted May 4, 2011 Author Share Posted May 4, 2011 it would, but you'll have to add two 4051 chips to it atmega8 has not enough pins to do full matrix decoding without additional hardware (it would decode keyboard, but not the console keys) anyways, here is finnished project including sourcecode if there will be enough intrest, i can make some boards for it, but not based on atmega8, as i don't see a point in using semi-working software usb solution its nice to have it, but its recognised every other time, and can't be left connected when PC boots up if anyone could build it and confirm its useablility it would be great - but somehow i doubt there will be a will to do it Sebastian Quote Link to comment Share on other sites More sharing options...
Defender II Posted May 4, 2011 Share Posted May 4, 2011 ok, shift/control issues fixed todo: remap cursor keys as they behave on real atari, remap some shifted keys to their positions (ie shift+2 or shift+7) if anyone could test it it would be great - yes - that requires building it - not that complicated though - just 4 resistors, few caps, crystal and 2 diodes so - anyone? (ps. hex file is constantly updated as i'm working on it) I would like to make one but my funds have been redirected to other purchases by a certain AA member with too many great projects!

candle Posted May 4, 2011 Author Share Posted May 4, 2011 you need $2 for MCU and $1 for rest of parts Quote Link to comment Share on other sites More sharing options...
venom4728a Posted May 5, 2011 Share Posted May 5, 2011 you need $2 for MCU and $1 for rest of parts I am interested in buying and building one, But I will need it for 600xl or 800xl, because I do not want to tear apart my working 1200xl. So what do I need to make the 6/800xl version, will the hex file be the same? And still new to this, so here is my newbie question how do i load the hex file into the chip? Will I need to purchase a eeprom burner? Thank for working on this Candle. ROBERT Quote Link to comment Share on other sites More sharing options...

yorgle Posted May 13, 2011 Share Posted May 13, 2011 (edited) My atmega arrived today. Hope to start building this weekend, but am confused as to the values for R1 and R4. Are these 2.2k and 4.7k resistors? Edited May 13, 2011 by yorgle Quote Link to comment Share on other sites More sharing options...
candle Posted May 13, 2011 Author Share Posted May 13, 2011 yes they are this type of marking is quite common in my line of work, so i've assumed it would be obvious to anyone - guess i was wrong Quote Link to comment Share on other sites More sharing options...
yorgle Posted May 14, 2011 Share Posted May 14, 2011 As you can see, I'm just a dabbler in electronics and mostly work off what little I can recall from way back when these computers were new. Thanks for the help. Quote Link to comment Share on other sites More sharing options...

Hello Yorgle is this the same Atmega chip that you purchased? https://www.jameco.com/webapp/wcs/stores/servlet/ProductDisplay?langId=-1&productId=248330&catalogId=10001&storeId=10001&krypto=O1zQhZvJNyfh3utFr4oNz3en04lxDxxKO%2FowxMemjvu5D18hfquJbgX6gxSW2WY5HvydAMraTLMh%0D%0AIlrVy%2FQ415y5lTDPztj4OUZh79%2Ba4usDwU1SfQBPvontE%2FeilAkVeCflN0hpgMOT1Rjro7y28XCX%0D%0Avja4lSJwBrti44lO48ykiWZ0kpqWrRvNKcK4v2uUGjz1dOpE9tGjksIdHuAFxiwqJyGodRhdpCqy%0D%0AjDEaE1wqn8VgZkGiAdaoWm8vdwMPdorouYRIM5dciRJIamkj1A%3D%3D&ddkey=https:StoreCatalogDrillDownView @ Candle for the 800xl version you say we need two 4150 chips, Can i get a little more info, I am not sure what to purchase? Thanks, I am ordering my parts right now, well some of them anyways. Thanks Robert Miller Quote Link to comment Share on other sites More sharing options...
Rybags Posted May 18, 2011 Share Posted May 18, 2011 That would be the 4051 multiplexor chips I'd say. Pokey uses 2 lots of 3 lines to give 8 combinations of row/column select for the keyscan, the 4051 multiplexors route those signals to the appropriate lines on the keyboard connector.

candle Posted September 4, 2011 Author Share Posted September 4, 2011 no hands, no cookies expecting everyone will do something for you while you yawn is pretty amusing way of going through life, isn't it? 1 Quote Link to comment Share on other sites More sharing options...
dkerfoot Posted September 5, 2011 Share Posted September 5, 2011 I've been using my 1200xl as my primary pc keyboard for over a year using a programmable keyboard controller via ps2. But my system can't have both atari and pc connected at the same time. Does your USB method have this same limitation? You should have no problem having the 1200xl connected via PS/2 and a separate USB keyboard (assuming your PC supports USB). Standard PS/2 keyboards play nicely with USB keyboards connected at the same time. The PS/2 usually needs to be connected at boot, but you can connect additional USB keyboards at any time.

Congratulations, it's pricks like you in the Atari community who killed ALL my Atari based projects. Thanks for confirming what a sad bunch the worst of you are. I am not lazy I work 65 hours a week and I don't have the time OR equipment to do anything like that. So much for helpful fellow Atarians Quote Link to comment Share on other sites More sharing options...
