- Thanks PCBWay.com - Spicy O'Clock is a new device to overclock
vintage Macs. Although it's designed primarily for 68040 machines, my Color Classic Mystic has a special trick - a PPC accelerator that's tied to 2x the '040 speed! So, hopefully, overclocking this board will overclock BOTH processors!
Or, it will explode.
Either way, it should be entertaining!

I’m so glad whiteboard Sean is a recurring character now lol
Shiteboard? No, we can't call him that. We'll stick with your choice.
@@TheMalMeninga Why are you calling Whiteboard Guy "Sean"? His name was never given, and it's OBVIOUSLY not our lovable host, Sean... since it's Whiteboard Guy... not Sean. :o

It’s like aging wheels’s clones that pop up in his videos
Your stable 48MHz 68040 Colour Classic is faster than a stock Quadra 840AV, the fastest 68k Mac. Congrats!
If the 601 is the limiting factor, you could get a 100/110MHz 601 chip and install it on the upgrade card.
Yeah, but is the PPC socketed on the upgrade card? If so, then that's an option. If not, eh, probably not.
Considering that once he removed the PowerPC from the equation and just overclocked the 040, and still ran into stability problems when trying to reach 50 MHz, something tells me that the PowerPC likely isn't the problem, or at least as big a contributor to the problem.
Someone in other video got the 040 high as 52 MHz but it had stability issues. He said the best speed without much issues is 44-45 MHz. 50 MHz can be done but got some bus errors.
@@GalenlevyPhoto I wonder if he could stably get to 50 MHz using either an LC040 or a 40 MHz chip. That way, the increase from the CPU's factory rated clock would be increased by 10 instead of 17 MHz. I know the board itself would run the chip at the bus speed of 33, but it would still be less of a strain on the CPU either way.
@@redleader6442 yeah it’s probably possible with a 40 MHz chip maybe if it’s not overclocked already.
The Wolf-3d performance vs. the DN3D performance tells you just how sloppy of a port Wolf 3D was on the Mac.
Surely there would be a better optimised source port by now?
For a 68K Mac? Maybe, I suspect the hard part is the Mac end of things and I don't know if the interest is there. But I'm not a Mac guy, fwiw, so if there's a recent source port that doesn't suck out there I probably wouldn't know about it.
Great video. Back in my tech days I had a customer leave behind a Color Classic with a bad logic board. It took more extensive modifications than the 040 mod, but I got it working with a 5500 logic board and later put a Sonnet G3 upgrade in it. I used it as my shop computer for quite a while. Everyone who saw it would ask why the heck I was using an old Color Classic, then they'd notice it was running OS 9...and then that it was screamin' fast.
Your multimeter jankiness is impressive, Sean.
I saw the bare-wire connectors and thought, "Surely he has a set of meter leads with alligator clips... oh. Close enough."
Wow! The overclock sure helped games too improve! Too bad it couldn’t run 50 Mhz 68040 stability. I think it’s probably the VRAM and the RAM preventing it from running stable.
yeah, that would explain the graphical glitches, likely parts of the graphics ram not updating proper
Fruit and red peppers go incredibly well together! I learned that with a friend who introduced me to Indian cuisine! I always have some kind of fruit spicy shutney on my fridge.
this retro YT channel is clearly doing very well given it can afford a dedicated whiteboard guy on staff
In the headlines today a Retro apple TH-camr's house disappeared into a strange spicy vortex...
Delicious vortex
@@ActionRetro 🤣🤣🤣 👍
i'm losing my f-ing mind laughing sooooooo hard over that spicy apple bit!
Finally I was able to watch this video. Was the spicy apple delicious? lol
I think the lack of voltage is one of the reasons why the clock didn't go up that much even with the 040. I feel that 5V is not enough. But you're the first to watch a video of overclocking a PPC card! I am happy with the results. Thanks so much!
You can gauge how old a person is by the minimum framerate they consider "playable". I'm guessing we are close to the same age. I've seen videos on youtube where people consider 20fps "unplayable"...back in my day 3fps wolf3d on your dad's work 386 was plenty!
Spicy is good
1:30 It's not really a chip, it's a four-pin oscillating crystal. The tall two-pin ones are used in ham radio gear, but you see crystals in various forms everywhere in electronics that needs a sync signal (AV stuff).
Congratulations on the overlock!
Because the LC575 board is very sensitive when it comes to overclocking, I'm curious if you tried stably overclocking beyond 45MHz (a) with the PPC card completely removed, or (b) with a different 040 CPU? I of course didn't have a PPC card in my testing, but once recapped with OS-CON caps and with a 40MHz rated 040 processor, I was able to achieve a stable 49MHz with Mr. Fahrenheit's 60ns VRAM (PCB by Stephen Arsenault) and 50MHz with the 2-chip SMC VRAM. So it could be either the CPU and/or the presence of the PPC upgrade card that is the limiting factor for overclocking the 040. Not that it matters in your case though because once the PPC card is installed, it seems to be the limiting factor at about 85MHz.
Even so, great work! I enjoyed this video very much! Hopefully it will inspire others to give Spicy O'Clock a try on their own 040 Macs!
Put some heat shrink on the alligator clips and just use them for pins so you're not having to make specific adapters for everything
Just found your channel and subbed immediately. This is the exact content I was looking for.
You earned a sub. Not for the showcasing of the Spicy O'Clock, but for eating hot sauce on an apple and actually liking it. Lol.
One of things i noticed is missing from the PPC Accelerator card - the L2 cache option. That would also explain the slow performance in games.
Ah yeah, I've been on the lookout for one
@@ActionRetro I can lend you mine?
Amazing results! Makes me so happy to see folks enjoying our products and pushing their machines to the limit!

Gotta say, I LOVE the addition of Whiteboard Guy. Dunno where you got him from, but his timing is
"Squeeze out every last megahurt..." 😂😂😂
I'll have the Macspice with extra RAM please.. and could i have some software to go?
would you like to supersize it
@@ActionRetro Of course.. You cannot have a Macspice without a supersize 3.5" platter
Awesome, loved how far you’ve pushed this. Silly question but would the non fpu 040 potentially clock faster?
Can't you ask Mr Colin aka Dosdude1 to put a faster cpu on that acceleratorcard? I think he would be glad to try it and help you out
That's a good idea! Also, I'm kind of curious if I could do it myself 😅
@@ActionRetro Its a BGA chip, you can do it yourself offcourse if you have the right tools, i suggest watching some of his videos to get an idea, i have 2 broken powerbook g4 and i want to try to put 1 g4 500mhz onto the cpu card of my pismo powerbook, and than try to run the impossible cat on it :p There is a rare card out there for the pismo that allows you to use an external AGP graphics card! I hope i can found one of these upgrades one day! I would love to see what the Pismo can do!
That spicy opening skit really mega hurts. 😀 I’m getting LGR vibes from the multiple Sean’s.
Making a Power PC into a spicy meat ball 🤌
Great video amazing that is one nice mac!
PCB WAYYYYYYYYYYYYYYY LOL sometimes I'll get that in my head and I'll just say it all day to myself...
*Sean adds hot sauce to a fruit*
Me, a mexican: He's starting to believe
Pro tip, try adding some hot sauce/chilli powder to some fruits, like apples, mangoes, oranges, cucumbers. Do not try with peaches or bananas....unless you want to lmao.
Great video. Do you have a source for the faster vram you mentioned?
Back in the mid 90s I got a CPU accelerator from Other World Computing and over clocked my 60 MHz 6100 (PPC 601) to 66 MHz! If I tried to go beyond that the Mac would crash. It was a noticeable improvement.
That was so fast that even the camera lost its focus at the end 😅
hahahahahaha
Hmm. I've been thinking about getting a second TRS80 Model 100 for shenanigans, and that system can be overclocked with crystal swaps. Even if this particular device wouldn't work, this is definitely an idea to explore. A variable oscillator of some sort should be doable.
I have a Centris 650 w/ 25MHz 68040 (not LC) and when I looked into overclocking info, I found references saying boosting the clock much above 27MHz w/o other mods can make I/O unstable, so recommended commercial overclocking boards (I think there's a 75-100MHz Daystar accelerator for it, but I've never been able to locate one). I actually still need to make sure the Centris 650 works first (Mac84 said they rarely have issues w/ caps or anything unless there's damage/corrosion), before I concern myself more with accelerating it.
I don't know what brand name you'll find them in in the US, but you should get some EZ-Hook or Parrot Clip test leads for your multimeter. They have little hooks that you can use to grip header pins, or legs on ICs hands free.
I thought you accidentally set an April fools video for August and not April
Do you have any links where we could find vram options?
Back in the day. OWC used to have this thing called the "rocket" which you literally placed over the oscillator on the board. Sure enough your CPU speed would register higher but the performance difference was almost non-existent. Still felt cool to put in though.
This makes me wanna finish my own cursed Color Classic... It had the floppy port modded into an external DB-25 connector, so the floppy drive could be plugged in externally, if I wanted it. In place of the floppy was a DVD-ROM CR-RW drive attached to a PATA card. The motherboard was either a 5400/6400 or 5500/6500 (I forget which). It had the TV/FM video system, it had the video out option, and it had a Wired4DVD hardware DVD decoder, and the thing that screwed me up, was rewiring the video internally. I LITERALLY had it working as a loose wire harness, and I did something assembling it, and I no longer got video. Other issues were hard drive and PSU placement, but now a days, this is easily solved, as I can just use a Compact Flash card, or one of the PATA SSDs featured here, or whatever. As for the floppy... It might not be a bad idea to just get a Floppy Emu or something and have an SD card slot for that. Maybe one of these days...
Did I mention, it's green! It's definitely a cursed Mac!
My friend did something similar to a 286 back in the 90s.
what a funny man i love these videos
I wonder if those long leads to mount it in the rear of the case are causing you problems. I know that fly leads like that are notorious for adding lots of stray capacitance on clock lines. It might be interesting to hook an oscilloscope up and try to generate an eye diagram to see how stable the clock is
Back in the day there were clip-on oscillator mods you could drop into the old 6100s and such that'd overclock the 66MHz 602 to 83MHz. it seems that most of the 601s could handle 83MHz no problem and that's where I'd recommend leaving it.
I have a 601/66 for my IIci, but it's actually slower than a fast 040 lol. I was thinking about trying a PiStorm in it and ditching the 601....
How do you have both a PowerPC and 68xxx in this machine?
Tbh i'm kind of interested in the idea of a motherboard replacement entirely. A new design that takes these cpus and the custom chips and such but is capable of handling increased clock speeds and without the cost cutting compromises.
didn't they mod these and run 6500 boards in them back in the day with 603e cpus @ 300mhz?
@@nix123ism A Lot of 603e boards were severely compromised in some way be it a 16 bit memory path to the ram or other things almost like intentionally gimping the performance of the machine.
God I love this channel
I've never owned a Mac. The last apple product I owned was an iPhone 4s. That's how long that's been. Yet I still watch all this man's videos for some reason 🧐🤔 I feel like that is an odd thing and maybe I'm a weirdo. Oh well.
bro i feel like stupid , i just discovered this channel pretty late..
Viper 2 fpga wont work in this thing? 68060 ppc setup
What are you running for storage? Is the old scsi hard drive gone ?
I've got a BlueSCSI in there
Nice! But it probably uses a RC oscillator. Temperature changes will also cause frequency changes in that case.
funny thing is i wanted to overclock my ppc 575 like yours but never found a 2nd stick of 70ns vram stick for my budget. I might later on through
Other than doing this, Which 040/LC series Mac would you be able to play these games on?
Wait… Sean! You didn’t mess with the PLL resistors? Now I feel old. Back in 1999 (when I hung out on AppleFritter) PLL modding was all the rage ;)
SEAN'S GONE CRAZY AGAIN
Within my collection of classic PCs the most I have is a 25mhz i486 🙃
Kind of Funny watching this video about Vintage mac's on a Modern M2 macbook
Someone needs to write a *GOOD* Macintosh emulator so that poor people like me can enjoy the wonders of old macs.
I'm going to need a glass of milk after watching this video!
That fan was not placed in an effective location. The 68040 was known for running hot and the fan was placed away from it. My Amiga was running an 040 at 55MHz but I clocked it down to 50 as I could feel the heat through the keyboard despite having a blower directed over the copper heatsink.
There are different revisions of the 68040 from the full CPU, FPU and MMU, however the EC while dropping both the FPU and MMU (neither used often on the Mac from my understanding) does not get as hot and is apparently easier to overclock. Also if you can get the real L88M mask (last produced revision) they are debugged and lowest heat.
Anyone tried putting an 68060 as a replacement?
@8:40 that board looks like it needs a bath in viniger? I really hope that is just flux residue on the board but even that is a bit acidic. I really suggest an ultrasonic cleaner to clean it perfect. to rare of a board to let it remain in that state.
i called it when i looked at it . its going to be happy at 45 and in 68040
So we just gonna ignore the oil smears on the board? We need to turn action retro into a restoration station
Sean, please don't go soft on me. ?"Too extreme" is exactly what I come here for.
Hell yeah, hot sauce.
Action retro is the goku of mac upgrading
Damn it now I want hot sauce ! LOL 🌶
From the thumbnail it looked like you had a crème brûlée torch to a pipe, now that I see that the pipe is an apple and what you did with it, I feel like I wasn't too far off.
640x480 resolution is overkill.
For 3D games with this config, 320 is the way.
Probably one of the reasons why it runs like a slideshow. Even a 386SX can run Wolf3D with a respectable framerate.
@@johntrevy1 Indeed, it has x4 pixels more to manipulate.
@@johntrevy1 the Mac port is really poorly optimised as well, since the engine was designed around x86. It’s kinda (but not really) like how you need more headroom to emulate a different architecture
can't you turn off texture mapping in the mac carmageddon?
Yes but it looked unplayably bad haha
@@ActionRetro in lan play it was worth it!
As a challenge for you, I wonder if you one day could try and hack the Mac OS X Public Beta (Kodiak) to run on one of your G3/G4 Upgraded Mac Clones. Wouldn't be too easy as the Beta will only work if you have a Mac from 1998-2000 and ATI graphics (1998-2000), but i challenge you to try that and achieve the impossible!
Can't wait for Whiteboard Guy to take over Earth
What’s the main hub to discuss vintage macs? Facebook groups, Reddit, forums?
I can't help but think about how i've been calling swollen batteries "spicy pillows"
I wouldn't exactly call any of those "playable." I'm not a Mac guy so I'm unfamiliar but I have a question. Can you not run Duke or Wolfenstein in PowerPC mode? Also why is Wolf3D on the Mac so slow? On PC you can run it on a 33mhz 386 at full speed. I would have thought you had plenty of speed there to run Wolf3D. Also If you do read this I know this is an over 1 year old video but it would be fun to see you run Linux on this machine. There are older versions of Debian that supported the 68040 and of course the PowerPC.
Chocolate Plague from puckerbutt farms is the best hot sauce ever, btw.
To run those games at playable framerates at 640x480 on a DOS machine, you would need something like a Pentium 166-200mhz.
I think a Pentium 200 classic does software Quake at 20 fps in 640x480.
So I guess you're looking for a similar Mac performance envelope.
ボットロッド Botrod. Clever, Koba-san.
why every single video that sponsored by PCBWay don't have announcement on intro?
I don't really get the Mystic upgrade. I mean, the LC575 is basically a CC, but with a bigger, higher-res screen, stereo sound and an on-board CD-ROM. Hell, thanks to so many people hacking them apart, there are probably fewer working LC575s than Mystic-upgraded CCs.
Is this your audition tape for Hot Ones?
I wish we had replaceable vram today
Imagine this macintosh with a g5 processor in it somehow
We have very different definitions of playable but nice upgrade nonetheless
Did you even test the Fahrenheith VRAM at all? If not, why even show it??
You should have had some music or MIDI playing on the computer while you changed the clock frequency.
5:17 Has science gone too far!?
Certainly "interesting" to see Carmageddon's performance after the overclock. Perhaps some things just weren't meant to be 😆
Why don't you try the pie amiga accelerator on a Mac? How come I have never seen a review of any Amiga hardware on this channel you could even review the mac emulator for the Amiga.
But can it run TempleOS?
No way will the holy operating system run on this abomination!!
I see playing videogames on macs hasn't changed in 20 years. It still sucks today.
it is more to do with the cpu chips, every manafacture has a variability - even newer cpu's ---- same model but vary in performance
Why not TAKKY it with a 5500 board and a sonnet 500MHz card? That’s what I am wanting to do! Plus you can add more RAM this way
Think if you add some faster VRAM you could push past 50MHz. Some ~spicy~ VRAM, if you will.
Next step: improvise cooling for higher OC? 🤔
Pork chops are good with applesauce .
Go on, put an Apple IIe card in it so you can run three different Apple generations
all my want
