Here's a few photos of my SpeedCard installed on my Mac SE motherboard... (And yes, I did later cover the windowed chips with tape to prevent erasure over time by UV.) And here's a photo of the SpeedCard owned by forum member @BFEXTU , who was an engineer who once worked for SuperMac...

Being budget minded should always be the number one priority, but I also wish to say the future is unknown. For the next 4 years, tariffs will have an impact on imports from China. That combined with inflation very well could drive up the cost of future productions. That's only speculation on...

Well, since you're a student of Japanese... 1994年から日本に住んでいます。僕のアドバイスは、まず話し言葉を学ぶことです。なぜなら、書き言葉よりも使う機会が多いですよ。書き言葉は、書類に記入する時や紙に書く必要がある時に主に使います。もちろん、読むことも重要な場合がありますが、今ではスマートフォンの内部カメラとGoogle翻訳のおかげで、さまざまな言語を読むことができます。 しかし、会話の日本語は非常に役立ちます。実際、日本を旅行するにはもちろん、日本に住むためには特に不可欠だと言えるでしょう。 :) With that said...

Welcome to TinkerDifferent, Conner. And thanks for letting us know about your YouTube channel, ComputerSmith. I think it's great when people decide to get on YouTube and share. But I do understand the folks who feel rather shy or who are worried about flames in the comments. Even so, life...

Not a "Digicard", but this "Sider" 20MB drive (the original was only 10MB) originally sold for $999 and had it's own card too: https://www.worthpoint.com/worthopedia/apple-sider-20mb-hard-drive-apple-ii-1827328361 This photo shows just how massive the thing is:

Absolutely. But again, that will require @Bolle to revise his circuit board to accommodate them. And it’s also important to remember that once that is done and people start buying them, eventually that too will run out in time because they aren’t made anymore either, from what I understand. And...

@jonshwenn Will Jacobs is shipping out my finished SE/30 Reloaded board this week, and I will show photos and of course do testing when it arrives. I paid him to swap out RAM sockets with new SIMM sockets that have metal tabs, but the Global inventory of those is rapidly diminishing and the...

Just want to make sure our forum keeps up with the latest info from @max1zzz ... Looking forward to the formal pricing and availability announcement (for the SCSI add-on card for the Rocket) when available, Max!

@Jockelill I am really very impressed with your work on that machine. That LED-lit cable is stunning. Did you happen to do any overclocking or add performance enhancements?

Reduce or disable the Disk Cache in the Memory Control Panel. After that, give RAM CHARGER a try.

Incorrect. Pin-1 is marked on the PCB and on the chip itself with a dot, and it should follow this diagram: You also need to verify if the trace I've circled is broken, because it looks that way. It must not be broken.

The difference between a "SWIM" and "IWM" is very important for the SE/30. As I said in my previous post, you need a SWIM, not an IWM chip. So long as you have a SWIM chip and not an IWM chip, then it is merely a matter of figuring out how to wiring it properly to your motherboard, without...

You would need the newer SWIM chip, not IWM, because you are using an SE/30. @Kai Robinson created a PLCC-to-DIP adapter in the past, but it was never publicly released. However, you would need the opposite of that — a DIP-to-PLCC adapter. That would be rather awkward to solder on, even if it...

I had an SE/30 board which had been through some repairs in the past, but which still had unexplainable intermittent issues that did not pertain to RAM sockets or the ROM socket. Leaked fluid had eaten through at least one trace underneath the RAM sockets, and the kind fellow I asked to repair...

UV solder mask. I guess Amiga of Rochester used that to cover exposed copper traces. Not an issue that I can see. Note necessarily a bad thing at all. My board looks like this on bottom... And like this on top... Again, that's UV solder mask, used to cover exposed copper. Not an issue...

I'm afraid my eyes aren't quite as speed as needed to follow that fast moving video! o_O:LOL: About the only thing I could spot is extra flux here... But as you can see from my board photo below, it's the GND side of axial cap C2, which isn't an issue... I do see you only have one side of...

Another important consideration the Brochure gives us is this... The amount of power required is an important point of consideration. In my IIci right now, I have the Rocket 33 (as an accelerator) with 32MB of RAM on it, along side a Thunder 24/GT graphics card, Apple cache card and 32MB of...

I've never removed the floppy drive controller chip, but perhaps someone who has worked on the SE/30 "Reloaded" build would have experience testing the board prior to having all chips soldered on? @Bolle @Willj I myself have seen horizontal lines under a variety of circumstances, especially...

Because you mention having a 30Video card, I will tag its creator, @zigzagjoe , to gather his thoughts. You mention having obtained an LCD too, but you seem to have the stock analog board, so I assume you do not have the full LCD kit from ZigZag...

It's at times like this that having more than one model of the same Mac is very handy. If you only had another SE/30 or SE, you could put your motherboard in that other machine and test it. If all is well, then you could do an Analog board swap. If all is well, then you could know if indeed...
