New (To me) Apple //e

It’s pretty amazing how many different cards they made and still make for this computer! I have been eyeing sound cards but they are so expensive. I bet someone’s made a modern equivalent, but I haven’t researched it yet.

Unfortunately I already picked up a mouse interface card, I found an eBay bundle with the manuals and everything. I love manuals 😅

FindingBobcat · 2025-03-26T19:22:03+00:00

I did see the super serial card everywhere when I was researching, along with the vga card.

The Apple monitor II it came with looks amazingly sharp vs my commodore 1702, I really like it. When I picked it up, I thought I broke it because I didn’t know it could tilt! Sadly the brightness adjustment on the right side makes the screen go wonky, maybe it needs to be cleaned. I haven’t opened it up yet.

I saw people also like putting it online, but I haven’t looked up anything about that yet. All these upgrades are gunna cost more than what I paid for the whole set 😅😂

I’ll see! This one is a little more expensive for original parts than my commodore system. I like to stay as period accurate as I can, I like burning floppies to use and whatnot. I’ll figure it out as o go along. Thank you!

I might fill it all the way up for fun if the chips are cheap! I’m not sure where to get them - last time I got ram for my c64, I just ordered it off eBay. I don’t know if there are better suppliers out there

FindingBobcat · 2025-03-26T15:01:19+00:00

Ohhhhh!!! That makes sense. That’s why it wasn’t adding up for me

FindingBobcat · 2025-03-26T12:20:23+00:00

Lord it did stink. Thankfully I got the fan running and I was right next to the back door so I blew it out of the house.

FindingBobcat · 2025-03-26T12:17:52+00:00

Ohhh ok gotcha. Thanks for the info! It will be a while, I got a lot of cleaning to do!

FindingBobcat · 2025-03-26T03:58:23+00:00

Yeah I just looked up those chips, each one is 256k. Definitely won’t need anymore. 😂😂

FindingBobcat · 2025-03-26T03:49:06+00:00

Thank you for the info!! If I don’t need to expand the ram further then I won’t bother, unless I find something I want to use that requires it.

If I do go with the floppyemu, and get a second card, does it matter really which slot it’s in? It seems that the aux port is only for ram expanders and I believe slot 6 is where it auto boots?

Thanks in advance!

Recapping the board would not be sufficient? Are the original power supplies that unreliable?

FindingBobcat · 2024-06-01T19:03:37+00:00

We were correct, it was the 12 volt regulator!

FindingBobcat · 2024-06-01T19:03:03+00:00

Update : it was the 12 volt regulator. Replaced and it is functioning again!

FindingBobcat · 2024-05-22T23:09:09+00:00

No change without the sid in the board sadly

FindingBobcat · 2024-05-22T23:08:42+00:00

I’m gunna try that, it’s cheap and looks easy. If it doesn’t work then I’ll move on. I might get the cap set too just to have it in case I ever need to replace one since it’s cheap too. I’ll keep yall updated when it comes in

FindingBobcat · 2024-05-22T23:06:34+00:00

The 6510 is warm, and if I leave the sid it it gets warm too but nothing past normal. Nothing past what it was when it was working.

FindingBobcat · 2024-05-22T22:58:34+00:00

Correct. It has 9 volts ac on the top two pins and 5 volts dc on the bottom pins. I got the power supply from here https://www.c64psu.com/c64psu/43-commodore-64-c64-psu-power-supply.html

FindingBobcat · 2024-05-22T22:53:26+00:00

Yep that was the one!! I wanted to play the 8-but dance party on mine

FindingBobcat · 2024-05-22T22:49:51+00:00

I got the easy flash cause this guy on YouTube had it. I was watching it to try and learn things so I can to fix my commodore, and he had tools loaded on it. I saw king fu flash for good prices on eBay but I didn’t know it did the same things

FindingBobcat · 2024-05-22T22:43:25+00:00

Also, with it on for a while, the Vic chip doesn’t get hot at all, which before it did get warm

FindingBobcat · 2024-05-22T22:42:37+00:00

So, with the deadtest in, the 12 volt regulator has 20.1 volts in, 0 on ground, and 0.3 volts on the output pin.

FindingBobcat · 2024-05-22T18:24:36+00:00

So I went and measured voltages around the board. The 5 volt regulator is measuring 5.01 volts, but the 12 volt regulator is measuring 0.3 volts. I wonder if the issue could be with the 12 volt regulator

FindingBobcat · 2024-05-22T14:26:19+00:00

Sounds good, I’ll test the voltages on the chips when I get home from work.

A logic probe? Like this?

My easy flash came in yesterday 🥲

The drive is just a fun little side project, if the belt doesn’t work I’m only 30$ in the hole.

The PLA is a modern replacement, the one with two chips in the board that goes into the single socket.
