how did you get a Serda Midi in the XEL?

DrV those resistors look like a machine bent the leads.. Did you use one of those pin bender guide thingys? Douglas

Would this be the same for an 1088XLD? Douglas

Too Late!! I thought it was foam from the anti-static and it was a mess. Douglas

I just fired up my 1088XLD and I get a eight note musical rif but my screen is blank. Color filled, one color adjustable by the pot, but nothing is loading from U1MB. I hear a slight sound when I hit F12 or F11 but I am getting no action on the screen. Its a great looking single color screen btw. I used Sdrive max on my XEL in order to do all of it's updates; U1MB firmware, XEL-CF3, and SdosX but I am stuck on the 1088XLD. I have changed out Sally Antic Pia And GTIA and the SRAM MIDI works and color renditioning of the background works but I get no boot up. No beeps other than the midi intro tune Any suggestions

Nope I was wrong. I looked closer and saw that I had an older version of the U1MB software installed in the XEL. Swapped again and found the correct version in that board. Woo Hoo! No bad U1MB. Sooooo there is an issue that tells the U1MB to boot up the OS that is inherent to my 1088XLD motherboard. Rockdoc2010

Well I verified that it most likely the U1MB. When I took out my U1MB from the 1088XLD and plugged into my 1088XEL I got the same full screen issue. I thought I was putting back the original into the XEL and thought I killed my XEL. I put the other U1MB back into my XEL and my system boot to spartados 4.49 WOO HOO it aint dead! So now I just need to pull the plcc from the bad U1MB and send it off to get reprogrammed. Assuming I can find a suitable vendor. Thank you for your time! Rockdoc2010

Yes I did and no joy with the chips I changed. I will try the GTIA now.

No it has not yet worked. I replaced the sally, antic pia and reseated the u1mb and the Sram . I am reassembling now.

I would be interested in the Atari 810 printer. Douglas

wondering what tape length you working with?

Where to find the acrylic case... anyone.. Douglas

I had a power supply go south on me and I got the boot error for known good drives. Check tour voltage on the power supply. Douglas

no worries.. nothing to see here.. move along... The VIDEO in is a much better place than the TV in.. The name is Dumass.

part number 399-9870-1-nd is not the same as in the BOM pn 399-4329-nd just wondering????

well this kinda sucks. Powered up my XEL for the first time and I got nothing. I do have 5vdc in all the right spots, but i have no video at all. Using composite at the moment but no joy. I swapped out my U1MB and my Sally and my rom and my GTIA and still nothing. placed a jumper at OSC but nothing. Douglas

well i have an APE and it works 90% I can use it to load images to the computer I can also use to load disk to the computer I cannot use it to to cut ATR . I cannot usu it to check drive status I am told that i have no com port connection. I have tried all comm ports help

okay so now i can install, but i missed the plug intsallaion

I am interested in one. PM me the info. Thanks Douglas

As it turns out when i opened up my happy drive J6 was in fact off of its plug my one pin. I am unaware as to what J6 does due to a loss of all my tech data. The plug was towards the front of the drive by one pin.

That's great thanks.. The square pad is the deal. The socket was inserted 180 out. SRAM on the way

Hey do you know if this is the proper orientation for the HART chip? The socket is reversed but the square pin is under pin one as this photo expresses.

Thank you very much I am currently clearing the holes of solder for a socket for the one 8k chip which will be replaced. Kinda wondering why the power up sequence don't work if you have a bad ram chip? Wouldda thought a controller chip..
