A must have. Digikey pn ED2108-ND CONN IC DIP SOCKET 40POS GOLD low profile and comes with a decoupling cap 8.10$ a piece Other sizes as well All my sockets on my 1200xl ran me about 80$

I hope I didnt offend anyone. After i reread my post my lack of commas can be annoying. In college I got nailed for too many and then for not enough. I think its awesome!! Which system did you use as far as motherboard design? 800xl?

Still wondering if it works? Great idea. Make it smaller. I think a daughter board would have been the way to go. Smaller footprint and separation of church from state. Power and audio and IO on the daughter board and data and actual computer on the main board. Makes a failure easier to repair. Im just saying. Cant wait to get a bare mb. But does it work

Damn autocorrect. My RV

I had two monitors. One avid and the other not. I did the avid mod on an 800xl. Not my favorite A8 computer but the video was crisp and the colors were very clean. Text was sharp and edge ghosting was reduced. But the 800xl went way of parts. Btw. Dont work on computers in uber dry desert in winter with two cats living in your every while going to college

Hello probably a mute point.. is the motherboard still available and is there a working unit yet? I see a LOT of modifications available but its as new as the latest pop music song.. is it standing the test? I have a lot of mods and just now have some time and money available.. 3/4 done with my bare 1200xl MB build BTW gold plated sockets with decoupling caps are a must! I even added the extra decoupling caps built into the MB an added additional insurance. Love a link to the bare MB.. Thanks Rockdoc2010

damn stuff to upload..

SOOOO... Sio2USB Works great KUDOS TO THE PRODUCT it will exist in my build! (I own three) SIO to FLASH.. 3/4 inch by 2 inch screen ... tiny flash drive.. sorry i suffer from CRS.. 512k Atarimax upgrade for 1200XL MYIDE original.. got to the point where it said what disk drive? I didn't have one ready at the time...(got one for an XEGS for sale!) board.. wires.. free postage.. 35$ thats 5 years ago.. 1meg ultimute that xe or xbxe.. like i will ever use that but i got it stereo dual pokey yotta yotta yotta is that jewish for a whole lotta shit? SOOOOO. I would love a 64k 600XL any sellers? I tried twice.. first class i ever had was soldering, electronics assembly.. so back off haters.. I got this!.. I have built the best looking 1200XL ever, bare board, gold plated, de-coupled.. brand new stuff in the best packages \ Do I Cram a 600XL or live with hella shit with a 1200? or so? a 60 gig and a 20 gig hard drive 2.5 form factor tight small.....

Not looking for a "Game Bank" as the 5200 had.. I disassy one of those only to find out the carts didn't fit, but a recent post had me thinking... What would it take to have two or three killer carts that could be switchable? I would think that no other switch but the voltage would be an issue, without voltage the carts cant send a signal thus be isolated..?? Just asking.. Douglas

I modded an 800XL with omni 80 column OS in 83 and I was very impressed! They are still available!

Not a fan of melding linix and Atari it just seems wrong. But Arduino can do just as much. The Raspberry is its own computer. The arduino is a better choice to convert and preserve the Atari. Douglas

i would like to program a Tiny for background rgb leds.. imagine a keyboard doing the FUJI colour scheme.. or based on the music/sounds Bueler Beuler Beuler?

yes it was steam driven...

Back in 1843 I installed an OS mod that gave my 800XL 80 columns Are you trying something else? Douglas

OSS CART is great. I went so far as putting basic xl into an original atari cart. it worked, but it was biotch I wanted uniformity.. retentive I am..

I ran a BBS back in 1991 but it was a Visual Basic Script board.. VBBS a mixture of A8, A16 and the original dirty pics.. DOOR GAMES are awesome!! "The Twilight Zone" Out of Whidbey Island Wa Douglas

2,659 posts If it aint broke, fix it anyway! Location:Houston, TX, USA Sent Today, 2:38 PM Hahah. Wow. Where'd you dig up that artifact? ok. First, Yeah thats a standard PORTB banked upgrade.. You cant use that in the same machine along with Ultimate 1meg., Second, theres no way in hell, in this day & age, I'd build a 256k upgrade using 256k x 1bit drams. Especially if you intend to install other upgrades on the same machine. Third, thats 64k base, plus 192k extended.. Basically like a Rambo XL or Newell 256k in an 800XL. Most things these days expect the "XE style" extended ram denominations.. eg. 320k, 576k, 1088k.. Not the XL (256, 512, 1024) ones.. You know what makes a damn good 600XL upgrade? Go ahead and do the standard 64k upgrade, and then do Hias's 576k SRAM upgrade. Its a single 512K SRAM chip, piggybacked on top of your OS ROM, a single 20 pin GAL, and about 12-wires to hook it up. Gives you true 130XE compatability (including separate antic/cpu access to extended ram, which that POOP upgrade doesn't so its not truly 130xe compatible), 576k (512k extended) ram, and if you install a switch, you can flip between 64k/320k/576k modes.. my original.. Jeff Poop 256k upgrade.. for your perusal..

So.. its guys like you that make guys like them look like armatures? Sorry busted glasses. cant see straight, horrendous on the equillibrium.. cant solder or glue titainium.. not done with the 1200XL monster board.. where do i do that pull for extsel? Douglas

i have a big collection, but i need to go thru them first.. Douglas..

how the hell did you make an XE version work with a 1200XL?

Polish Vodka is the BEST!

Couldnt you get a rockwell 6502 chip that clocks at 4.77MH? Just thinking about old chips and the like.. The rest of the chips may not play nice with the aforementioned CPU? just asking... Douglas

So now what to do with the 8 switch dip package with no instructions...

I now have a second Alphacom42 this one with an RS-232 interface.. where is my 850?

Cool i just bought one.. Douglas Berlier aka rockdoc2010 on AA I sent 49Eu for taxes and shipping and the like.. enjoy!
