Everything you wanted to know about custom ROM SIMMs, and so much more! This video took me 7 weeks to make. Much of that time was spent in testing, and in working with Doug Brown and the CayMac team. The end result is amazing. Don't miss the text description on YouTube because I packed it...

I am posting this in the Compact Mac sub-forum because most of us tend to use custom ROM SIMMs on the SE/30. I've been doing the prep work for a video about the ROM SIMM Programmer and ROM SIMMs currently sold today. One big issue is the thickness of the ROM SIMMs and the finicky nature of the...

I am curious what issues people need to be aware of when buying a Macintosh Portable, especially the backlit model (5126). I realize Portables won't power on without a good battery, but new batteries like this are sold on EBAY. Maybe some of you can share experiences with those. I also realize...

Folks, I discovered something new with my SE/30 & FloppyEMU last night. I reported it to Steve Chamberlin of BMOW, and he kindly wrote back with the answer. I thought it might be a situation where some of you vintage Mac hackers might get some kicks out of this. BACKGROUND As you know, the...

Now available on Archive ORG: https://archive.org/details/apple-t-shirts/mode/2up I ran across a post by the book owner on FaceBook and lamented the high cost of the out-of-print book and the fact there was no scan of it. He very kindly scanned it and put it on the Wayback Machine today...

I spotted a fascinating little gadget in a post to the Vintage Apple Macintosh Enthusiasts Facebook group in April this year. I sent a PM to one of the co-creators, Joakim Larsson , and that led us down the rabbit hole of conversations which resulted in me buying one and then doing the full...

After a bit of research and having the need to make temperature measurements over time (i.e., "data logging"), I decided to buy the 121GW multimeter, from EEVBlog. That prompted me to make a detailed video review of it, in which I compare that meter with some of the Flukes I use at the office...

I'm pleased to report there is now a fix for audio glitching when using a Carrera040 accelerator card (original or clone) in an SE/30, thanks to a revised Control Panel from @Bolle and GeekDot. I have uploaded it to the Macintosh Garden here...

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...

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...

@Kai Robinson kindly offered us some wonderful well-wishing last year, and with it being Christmas today here in Japan I felt compelled to do the same. Forum membership has grown considerably in 2022. I know everyone here at TinkerDifferent would like to extend a huge thank you and warm...

I posted about this over at the Apple II Enthusiasts group on FaceBook, and I also sent Henry of ReactiveMicro an email, but thus far I've not been able to determine the cause of the problem I am having, which I described in detail in the following unlisted video on YouTube... PROBLEM QUICK...

My Part II video on this topic turned out to be longer than I thought, but it's fully indexed so you can jump to the parts which interest you. Even so, it's highly edited such that all the boring stuff is left out and what remains is only the juicy meat. :-) This really is about how useful the...

Although I've been a Mac fan since 1984, I'm still new to the Apple II. But my recent purchase of an Apple IIe Card & Y-cable for my Macintosh Color Classic Mystic has been a fun learning experience. I made this video showing how to recap the card and to provide a general overview of the...

While digging up info on the LSI LOGIC chip used on the Apple IIe Card, I came across a book about LSI which provided some very interest historical info I had never read anywhere else. Amazing what could have been! One day Doug came in with a copy of EE Times. It had a photo of Steve Jobs and...

SOLVED! Solution here While working on my IIe Card video, I've run up against a number of things I cannot explain. We had a good discussion here recently, but I feel this needs its own thread with a more specific title, in the proper sub-forum (which is perhaps best suited here rather than in...

I am currently filming a new video about the Apple IIe Card in my Color Classic Mystic. As many of you know, I performed the VGA mod on this CC earlier this year, which boost the stock resolution of 512x384 to 640x480. Smaller pixels means everything is smaller, but the upside is you can run...

After watching this Recode interview with Jony Ive, Laurene P. Jobs, and Tim Cook about the influence of Steve Jobs, I must say it really does harmonize with what I have long felt about Steve. I highly recommend you give it a complete watch. I especially appreciated the discussion around the...

This post is not about listing every vendor of floppy disks out there, in 2022, especially since most of us know they can most often be found on EBAY here and Amazon(USA) here. Today, I read this recent INTERVIEW with Tom Persky, who is owner of floppydisk.com. The article inspired me to email...

I've been testing my inventory of 1MB RAM SIMMs using my Mac SE Reloaded machine, and with one particular set of SIMMs, I get a Sad Mac at cold boot showing these 2 lines: 00000004 <— "Bank A" 00004000 <— Failed bits... AABBCCDD AA = bits 31-24 BB = bits 23-16 CC = bits 15-8 DD = bits 7-0...
