Yes, that parallels the finding I put forth in my opening post. However, as I asked you in my previous post, does that information come from your own personal experience, or did you read about it somewhere? If you did read about it somewhere, could you please provide a link to that information...

No, I absolutely do NOT realize that, as per my previous posts on the matter! :-) You seem to suggest in your second sentence that only 8pcs of 16MB SIMMs can be used in the SE/30. Not sure about the meaning of "If you only have 4x 16MB SIMMs" because in the second half of that second...

Thanks, Kai. Well, I don't have that kind to test. But if anyone should know if a PAL SIMM can work at all in an SE/30 it would be @Zane Kaminski, seeing that Garrett's Workshop created them! https://www.tindie.com/products/garrettswrkshp/gw4194a-4x4mb-pal-simm-ram-for-mac-ii-and-iix/...

Thanks, Eric. I actually was using the OS 8.1 driver prior to the Dec. 2022 firmware update, but if I recall correctly, I had issues with my Mac SE, which forced me to reverted the drivers back to v7.3.5, async in order to retain the broadest 68K Mac compatibility. It tend to swap my BlueSCSI...

Thank you for making time to share your thoughts. Through the years, I've not read any stories about the SE/30 having issues with 16MB SIMMs, but I will admit that so few people seem to have them that the data pool is rather small. Below is a graphic I extracted from an old book on Mac...

Stock SE/30 ROM. Nothing unique about the ROM.

@YMK You are correct about the error in that LEM article! Wow. I never noticed that. BTW, this discussion explains why adding more VRAM to an SE/30 won't do anything. Thank you for the PDF. I read most of it, including the last 3 pages, but that closing text pertains mostly to the Macintosh...

If price matters most to you, and if you prefer not to use my Mouser Cart, I do see that Console5 has a US edition Analog Board recap kit below, and it seems to include the RIFA caps too... https://console5.com/store/macintosh-128k-512k-plus-analog-pcb-cap-kit-630-0102-661-0462.html However...

My suggested replacement cap is a FILM type capacitor. Those almost always have very high voltage ratings. And that significantly higher voltage rating doesn't matter at all. Most people who lack a schematic just need to recap based on the stock cap's marked voltage and buy the same or...

@keelus My complete Mouser Cart is here, and my video is here. See the text description under the video on Youtube for lots more info! (For US Analog Boards only, not international.) There is a cap kit for the International Analog Boards on Console5 here, but sadly, it doesn't include the...

According to this LEM page, unless you are installing 17MB, you should be putting the larger sized SIMMs into Bank A, with the smaller sized SIMMs into Bank B. However, when I put four 16MB SIMMs into Bank A, and nothing in Bank B, I get death chimes and a crazy display. But if then put 4...

I made some time after work this evening to test all 3 of my BlueSCSI units (2 of which are now overclocked) on a PowerMac 9600/300 with a Buffalo 400MHz G4 (7400) CPU card installed. All were connected externally, with the internal type BlueSCSIs connecting via OverEasy II Rev.B. The minimum...

Hi, Folks! I have 3 "high quality" (well constructed) BlueSCSI units that I acquired from @Kay K.M.Mods, each with different processors... After a discussion with @eric yesterday, I decided to proceed with overclocking these units to see what would happen. My rather straightforward method...

My first computer was the 128K in 1984; and at the time, I had a 300 baud Maccessories portable modem, which included a nifty soft case... Back then, even that pathetically slow modem cost $140... But it still cost less than the $200+ that was common for 300 baud at the time, and 1200 baud...

Nope. :-) Back in the day, I was only into basic dial-up BBSs.

I grew weary of FB for the exact same reason. I didn't care for what my "friends" were eating or their chain-mail style memes. However, I chose to say on FB because I live outside my home country and still have a lot of friends and family on FB. It's a way to keep in touch. But more than...

Thanks for doing that. Interestingly, it's more of a Mac Plus motherboard drawing than a 128K drawing due to the connectors and the two torrid coils. And yet, the RAM chips to the right of the CPU are clearly from the earlier motherboards. Have a look at the obvious differences... Plus...

Thank you! I was actually thinking about just that while taking a shower this morning, prior to reading your post. I installed it in Basilisk II, set it to SE/30, restarted, launched Snooper, and boom! Got the SE/30 motherboard. So I will slowly add these to the opening post so anyone can...

https://macintoshgarden.org/apps/snooper-20 I edited my opening post to add that Macintosh Garden download page. It's a great app to use regularly anyway, screenshots aside. Thanks for the link on your website, by the way. A lot of people overlook what kind of caps are best...

Starting with this post, I found that Snooper 2 has some interesting motherboard photos, worthy of extraction. If you follow that discussion, you will see that it concluded with the finding that we cannot extract them from the PICT resource of the Snooper app. The only reasonable method of...
