I would suggest you halt everything until you've recapped, and my advice is to use OS-CON or similar solid polymer capacitors with super low ESR to make 100% sure the craziness you are seeing is in no way whatsoever related to voltage instability on the motherboard, which likely is the case if...

I can only say that those test results don't follow what I've been seeing in my 4 months of testing on the LC575 motherboard, so we really, really need another LC475 user who also has Spicy O'Clock to explain in detail what happens on their machine, at the same clock frequencies you used, and...

I have access to 2 scopes at the office, both 100MHz only. I also have a logic analyzer, but it too maxes out at 100MHz, and only for 2 channels. @Zane Kaminski You do a lot of design and testing work. What reasonably priced 500MHz scope would you recommend for general use? Being able to read...

Keep in mind that is 40mm. The heatsink I will show in my forthcoming video is 45mm and covers the entire top surface area of the chip. I think it's best to cover most of the chip where possible to maximize cooling.

Thanks! :)

Because the MC88916DW80 was mentioned by Kay, I should remind everyone that on my LC575 board, I have the slower MC88916DW55 chip. You can see that chip in this section of my Part I video. But despite that slower DW55 chip, I have broken the 50MHz barrier with Kay's new 2-chip VRAM. There's...

Eric, I just confirmed that FPS does not appear on my 68K Mac after changing the screen size. So what you are seeing is either a PPC only feature or maybe there was some code entered in the past on your machine that enabled it. Anyway, thank you! --James

I've installed Duke Nukem 3D on my Color Classic Mystic: https://macintoshgarden.org/games/duke-nukem-3d-atomic-edition I want to have it auto-play on a CC while I sit beside the machine and shoot a segment for my next video. Of course, I could do a "hack" whereby I sit down and play the game...

Thanks. Well, I need to test it again, but in all my countless hours and days and weeks of testing with Doom II, no screen size changes I ever made resulted in FPS showing. So the key difference here would appear to be the fact I am using a 68K Mac while you are on a PPC machine. I will...

Was I mistaken in assuming that the guy in France (Silicon Insider) is the creator of that VRAM on EBAY? I thought those VRAM SIMMs where his creation.

I was filming and editing last night and had no time to test that. My time this evening is also limited, but just to quickly confirm, can you tell me the exact steps that need to be done? For example... 1. Launch Doom II. 2. Change Screen Size slider to anything at all. 3. Play game and enjoy...

@Zane Kaminski I was just talking to @Kay K.M.Mods yesterday about the $25 50ns VRAM from Silicon Insider. It's for PPC Macs and therefore not pin-compatible with the LC575 motherboard, but when my eyes spotted that my brain was laser-focused on the "50ns" part! The chip capacity is larger...

Thank you, Eric! I already filmed the games segment of my video last night, and I don't have time to add new content to that, but just to confirm, when you changed screen size in Doom II, you were given an option for FPS, or it was automatic? I ask because I've changed the screen size in the...

Yes, I am wondering how to invoke an in-game console on the Mac version, but so far, I've not figured out a way.

Do any of you know how to display the Frame Rate in Doom II or Marathon or Wolfenstein 3D or Dark Forces? I'm overclocking my Color Classic Mystic and want to show before/after FPS. https://macintoshgarden.org/games/doom-ii

Thank you very much for making time to watch my screencast! It seems you are suggesting we consider 1 of 2 things: 1. Rebuild the record content inside a different database and then hire someone to build a custom UI on top of that. or 2. Hire a PHP programmer to do the API interface with our...

Thank you for the suggestions. I'd never heard of Caddy before, but looking at the website now, I see it is web server software. Since we are on a shared hosting server (not a dedicated server), which is deliberate on our part to keep our web serving costs to a rock bottom minimum, I don't see...

Sorry for my delayed reply. I am just too busy to reply when at home these days with my wife still hospitalized, but now that I am here at work, I can make the time since, technically speaking, this is work-related. Looking at my website folder hierarchy, I see this: home > public_html > dev...

Thank you for the recommendation. I suppose it boils down to what our web host provider will allow. We pay MacUSA to host our FileMaker databases, but we pay a different company (Superior Host) to host our websites. Our websites are on shared hosting, not a dedicated server. That keeps costs...

Work related question today. Since I am talking about "vintage" software for Macs, I felt it only reasonable to post my query on TinkerDifferent! :-) Many years ago, my employer paid a web programmer to build a mySQL database for us, such that we could put our car security related vehicle...
