    WHAT is wrong with this picture?

     

    Turns out i didn't notice the fact the pins had no holes.

     

    Two 18 pin gold machine pin sockets were bad. 

    My repair is to suck as much solder out as you can with a hot soldered wet wick, then cut the plastic away so that you can get to the pins..

    Then a hand drill and the correct bit to clear the via's of solder..

     

    drill from the solder side to clear the holes to ensure you don't destroy a pad. 

     

    This board has great via's and you can do it!

    I pulled a happy out of storage and it did not do the power on sequence.

    I pulled the drive mechanism and tried it in a known good drive and the mech worked.

    I pulled the two chips from a known good board and installed the happy in it.

    No Joy!

    Your not gonna believe this.....

    I then installed the two chips that i removed from the drive when i installed it back in 1984. I still had the chips!!!!!!!!

    Now I have a working 1050 drive but the happy is dead.

     

    I am in need of and where do I find the following..

    I am interested in looking at and watching and debugging ansi graphics for the opening screens for old school BBS's.

    I may incorporate the coding into a new game and i want a database of images to get an idea as to where i can go with this artistic medium.

     

    I found a lot a few years back but cant find it now

     

    I wish to add a few atacsii vignettes into my game as it progresses. I wonder if it requires a modem line to run?

     

    Thanks, Douglas

    Well, I made much better progress than I thought I would this evening. All soldering is done, save for the Level 2 board. No pics of the back yet as the board is still caked in flux.

     

    It's neat - take and my previous image, it's a great before & after, almost perfectly lined up. Wish I could properly edit photos to make them match.

     

    BTW - I'll have more images posted in higher resolution at my Flickr site - 1088XLD album is https://www.flickr.com/photos/[email protected]/albums/72157705660251381

    So the cartridge slot will have to be milled out of the top case? The 90 degree angled slot of the 1200XL could work here with an extension to the backplate?? just haven't seen the cart come to fruition yet.

    Yes - I hope it doesn't re-yellow on me. Oddly, none of the gear I owned ever turned colour. Non smoker, and always covered, out of sunlight, and temp stored. I am a "night owl". Light sensitive, prefer the dark, etc. This was an ebay item, broken, that I was trying to fix.

     

    Oh - no tricks. 40 vol cream lightener, saran wrap, and sunlight. Re-applied every 30 minutes for 3 hours, and I had this perfect result. Ambient temp was 73, moderate humidity when I did this (outdoors).

     

    where do you find 40 volume cream lightener?

    Was it an Atari?

    I landed in Kingman Arizona with a dead radiator. The Business i arrived at was a radiator shop. OLD SCHOOL!

    I saw him look up my part and it was definitely an 8 bit program. It probably wasn't an Atari but the whole process took me back to the 8-bit.

    His inventory was entirely driven by an 8-bit computer and the invoice was a digital representation of an 8-bit era printer.

     

    He still runs his tight inventory and clean billing on an eight bit. he didn't look for the part online! he saw that he had it in stock!

     

    I was blown away! and when your driving cross country.. he didn't rape me for cost. LABOR cost a bit but i made it on my way with no more overheating.

     

    eight bit worked for me.

    I am not going to start a new thread.

     

    I just wanted to show you my build.

    It cost a bit more, more..

     

    But i have no intention or need to do this again with gold contacts.

    I will do the same when the 1088XLD comes of age.

    I was the last of the few that did this.. I wish I was involved when it happened.

     

    I cannot wait until i get my flashed PIC's
