Apple II

Hello!

In the past few weeks, I acquired an Apple II Plus that seems to have a graphics error. Whenever I attempt to boot the computer, vertical lines appear instead of the normal startup screen. I don't know if a chip is fried or what. I've added a high resolution image of the motherboard below for reference. Any help is appreciated!

Thanks
Kevin

P.S. - I should add that I'm an amateur when it comes to pre-mac era Apple machines and this is my first Apple II.

Hi, all

Any one has idea on Apple IIGS ROM03 with boot screen first line "Turbo->28" rather than "Apple IIGS"? Is it an early ROM03 unit, developer unit or?
I couldn't find any information from the web.

Thanks,
Michael

I thought I had submitted this a day or so ago, it looks like I goofed something up, so I will try again.

Well,

I soldered the prototype of the Apple IIe diagnostics together today with the parts I sourced and it works!!!!

I included a picture of the screen and the card.

I soldered Machined sockets on the card so I can use it as a test Jig. Also, I didn't solder the black ROM socket either.

I am going to put a few more of these together this weekend, but you will see them soon on Henry's RM page to buy.

WooHoo!!!

Thanks,
Jay

I added another board I made from another fabricator and it worked too!!!
