Thanks for the reminder, Kai. I also just remembered that I could use the output from Spicy O'Clock too. So I will give both of those a try and see what happens.

@trag I've been exchanging PMs with someone who asked me to do various tests. I made a couple videos of those tests, where I had the XC88916DW55 chip desoldered from the LC575 motherboard and placed inside an SMD to DIP socket for my breadboard. Even without any SYNC input, I get roughly a...

I thought long and hard about which VGA mod to do. Because I lacked experience, I deferred to the experts and did the standard VGA mod, which is a low voltage mod that puts less strain on the Analog Board. But if I were to do it again, I probably would have just swapped out the spinning hard...

I'm thrilled to see you have your Color Classic working nicely, Kenny. @Kay K.M.Mods kindly got me started with the Color Classic a few years ago, and I've been hooked since. The machine is almost like a drug. Before owning one, I didn't think much of the industrial design, but then after...

I removed the XC88916DW55 chip this evening. It's all ready for a replacement. And I do hope that is the fix. Even so, I won't know until I try a chip swap.

I've not heard back from Kai, so it could be he can't find his stash. I emailed you just now about acquiring some of your chips. My DW55 chip should theoretically only handle up to 55MHz on the 2X output. Meaning, there's also a 1X output. For example, if you run an 040 CPU at 25MHz (1x...

Thank you for the advice, Colin! I spent a half hour speaking to Mouser via Chat. The best they could do was recommend alternative parts, non of which are pin compatible: 8-pin PLL 16-pin PLL 1 16-pin PLL 2 16-pin PLL 3 In contrast, the 88916DW is a 20-pin part, specifically made for use...

Somehow I killed my Mystic merely by making some 4-wire resistance measurements in the vicinity of the XC88916DW55 chip on my LC575 motherboard. I know it's a problem on the motherboard, not the analog board. I believe the 88916DW chip is now bad because when I put my scope on it, the Q0 and...

Well, please don't throw in the towel yet. I'm sure @Kai Robinson might have some more ideas up his sleeve.

Well, it's going to take time to figure out which chips might be damaged due to the error of putting the 65C22N in the socket intended for a 53C80. You can see from my previous post that the correct SCSI chip has multiple Grounds, which means every pin marked GND gets constant Ground. Which...

Pretty incredible. Thank you for sharing that, @andrew !

Yikes! I overlooked that error when examining his photo, Kai. Could that have killed another chip on the board? Fred, can you please tell us exactly what you did prior to reporting that you are still stuck? (For example, I gave you a 7-point list in my previous post.) Even so, my concern...

So you removed the jumper and tested and saw EXACTLY the same pattern on your CRT? You then changed RAM to another set of four 1MB SIMMs? You know that the previous four SIMMs and the newly swapped-in four SIMMs are all known-good and have zero issues as per your testing in other machines? If...

@fred1212 8pcs of TMS4C1024DJ per SIMM indicates each SIMM is 1MB. You have 4pcs of 1MB SIMM yielding 4MB of RAM in total. You need to remove the jumper wire you soldered in at J16... Yes, I know it indicates "2/4M" but in reality you must have no jumper at all there when using four 1MB...

Almost every time I access my PMs, I have a need to keywordーsearch past conversations. Alas! No Can Do! The good news is that there's a Xenforo plugin that gives us what Xenforo should do out-of-the-box: https://xenforo.com/community/resources/conversation-search.5788/ $35 is a small...

In August 2022, @Kay K.M.Mods created what I consider an OUTSTANDING upgrade for the Color Classic MYSTIC called: FLIPPY FLOPPY. I'm a big-time FloppyEMU user. It always frustrated me to my core when I reflected on how my otherwise great MYSTIC doesn't have an external floppy drive port on...

I did not view it as “mocking“ anyone. A little bit of poking fun with people who are understanding, just like Eric did to me earlier and I accepted it without being upset. But it seems rather clear you took it very personally and are upset. So here’s how I’m going to solve that problem. I will...

A mass emailing to all forum members is a decision the board must make. I must say though that it would have a major impact on voter turn-out for any given cause. However, the board has not send out mass email notifications during past board member elections, so I suspect they won't do it in...

I don't wish to say anything for or against a TERM LENGTH change so as not to influence anyone, but to help us all keep "the community" in perspective... TinkerDifferent has 1522 members as of the time I posted this. 56 have voted. That means only 3.4% have voted. And yet, there are just...

I'm pleased with all the recent posts. Sure, some are off topic, but that only makes the case for my earlier post, which in comparison really isn't OT at all! (y) Don't take this as chastisement though, because I'm one of those easy-going, freedom-loving types that doesn't get upset by OT...
