i had to recap the 400W power supply of my G4 MDD and now it's been running perfectly on and off for about 2 years, hooked up to a CRT studio display. it's beautiful. all it just needs now is solid state storage, hopefully that will be more feasible when it becomes cheap again

OS X definitely does the checks, and you can check in system profiler if something is amiss or has failed.

well, tested the computer some more and it does work, but disables the L2 cache for whatever reason. maybe lack of address lines or something. gauge pro also doesn't properly see my bus overclock, and assumes the CPU is running at 266MHz with the 66MHz bus even though i had set the bus to run at...

welp, got the new chips in and well... it still isn't passing the mac os 9 built in memory test for cache. starting to think its either address lines or firmware related. dunno if the firmware on here has ever been updated, as a matter of fact. i know for certain these chips are good.

could be the chips...

might need some assistance. @LightBulbFun @dosdude1 have you two ever attempted this before?

decided to just only have the RAM upgraded to 64MB because i can't bother finding the right decoupling caps that are supposed to work. also i installed L2 chips from a powerbook G3 lombard CPU card, and it still fails the cache test... wondering if the ROM just doesn't like 1MB cache...

well... i just tested the motherboard and now it is giving me a rather distorted startup chime with no further activity. i suspect this is a memory issue. might have to use other RAM chips.

i might have to have my firmware modified for both 128MB of RAM and the 1MB of L2 cache. still working on the arduous process of soldering everything especially those damn tiny decoupling capacitors needed for the extra RAM chips

sorry for being so late, just saw this post recommended to me. yes you can absolutely upgrade the L2 cache on these to 1MB, i've done it myself. just get yourself 2 128Kx36 chips like on G4 CPU cards and solder those on.

i saw an article on low end mac where someone maxed out the clamshell's onboard memory to 128MB. at first i wasn't gonna do this but then i realized while i'm at it, why not? also bad news... USPS mis-delivered my cache chips to another house apparently so i don't know if or when i'll be...

yes it is getting power. just not being picked up in the system. looked at schematics and checked all traces, they are fine.

bad news... the imagewriter II i got has a loose return switch and i'm not quite sure how to remove the printhead without damaging anything. good news? i got the macintosh SE FDHD working, its in very good shape too. barely, probably never even yellowed. installed an 80MB hard drive, recapped...

compaq presario 2500 (2580us), typical windows XP laptop that has the absolute slowest install of XP i've ever seen. took several minutes just to open my computer. definitely putting 2k on it

got the color classic and everything else! sadly theres something up with the egret/cuda on the CC because it isn't turning on even after a recap and a thorough cleaning.

yeah thats what i figured...

sadly the cache is not working due to heat damage, i put my heat gun too close to each chip and heard a pop sound when i was removing them from the G4 CPU card. i am waiting on replacement chips from ebay. also, i have managed to overclock the bus to 100MHz and the CPU to 400MHz (100x4), will...

someone made a package of optimizations for 10.4.11 that make it run more like panther or jaguar, and ive run it on other G3 macs. it performs quite well.

hello everyone! i am undertaking a nice little project with an ibook clamshell i just acquired; upgrading the living hell out of it. so far i've done the following: max out the RAM, upgrade the hard drive to a 30GB SSD, and (attempt to) swap the 512KB L2 cache for 1MB. this mainly went smoothly...

the LC III has a weird issue unfortunately. it does not seem to be reading floppies or writing to them. even with other drives the issue persists. i have recapped it and everything, no bad traces spotted too. i wonder if an IC is bad?
