help needed! - Apple II+

Hello everyone, please bear with me, this is the first time that I have used this forum, and I am new here. (clearly)

Anyways, I recently got the chance of a lifetime from a family member who was throwing out their old Apple II+. It's the black model, I don't know what year or specs yet, because I have yet to get the computer working. I opened it up already, and attempted reseating some of the IC chips and RAM chips, (I think that's what they're called) and unfortunately, I ended up snapping the pins on two of the chips. I will hopefully be able to re-solder these at a later date, as ATM I don't have access to a soldering iron.

The issue that I have looks something like this picture here, when I power the computer on:

I am a "young one" (<20 years) so I don't know much about these, again.

Thank you for the help, I really appreciate this. I have much hope and desire to get this machine working!

Some help ...

Is there any way you can snap a photo of the top of the damaged IC's? Most are available on eBay for just a few dollars each.
Many start with 74LS but the RAM memory should have a 4116 indication (or the likes) Let us know what you need to start with.

BTW, the black model was marked by Bell & Howell. Basically an Apple II Plus model supplied with a full 64K of RAM. (48K on Motherboard, 16K in Slot 0)

You are partially correct. It

You are partially correct. It is 64k, I believe, but there is no Bell & Howell. I will attach a picture of the chassis and the IC chips.

Here is a picture of the chips, serial number, and chassis of the II: link (imgur)

Thank you for your response, I really appreciate it!

Thanks for posting your photo

Thanks for posting your photo.
Looking at the chips that you show, I see many with corrosion across the pins.
From the onset, it looks like you'll need to pull each chip and clean the pins before re-inserting.
Also, it looks like the IC sockets may also have corrosion inside or below where you cannot see. In that case,
you'll need to remove the socket, clean, and replace. There are some cleaners that might do the trick but the corrosion
(from your photos) looks pretty serious. This will likely require professional cleaning.
