I understand. I don't like trying to boot from USB on these PPC machines because I've had nothing but issues, and wasted hours trying.

I'll track down PC-66 ram as I do not have any.

im just trying to guess what the problem could be... i may not be correct. im just trying to give u ideas to try but the everymac page says pc66 - and i have had similar problems with ram incompatibilities with PC motherboards where the motherboard would not boot with pc100 installed...amd would only boot when i installed pc66 ram... to make it even more confusing -- later on i found that another brand of pc100 worked fine... its a complicated thing.. sometimes ram will work for a bit and then refuse to work.. this is why vendors provided QVL lists of ram that was tested to work properly..

also-- booting from c.. unless u have the proper keyboard that came with it. or a similar mac usb keyboard from 1998/1999 (should have a power button it aswell) it may not work correct for example using a keyboard from a imac g5 or powermac g5 on a g4 will give the same result.. holding c does not work properly. unless its the right keyboard for the mac..

if the powerbutton on the usb keyboard turns the imac on it should work fine.

I've noticed that some macs, if they are on the folder screen with no OS on a HD, when a CD is inserted, it'll boot from the CD without pressing C.

also remember that this imac has the bug which requires the first partition on the disk having to be under 8gb in size for it to boot.

also the partition type on the hard drive has to be "APM" apple partition map.. if its never been used before its probably in "MBR" partition type unless u have repartitioned it using another mac . i doubt that it would be in "GPT" partition type if its "new old stock" 50gb IDE drive..
so u have to repartition this disk.. the way i would do it is to burn disc 1 from the mac os x panther cds on another machine using a blank CD-R and then be sure to burn it on a slower speed such as 1x, or 4x, or 8x (u can download panther cds here: http://macintoshgarden.org/apps/mac-osx-mac-os-10-ppc)

after the disc is burned boot up into mac os x setup, and use disk utility to partition the drive into at least 2 partitions, with the first of the two being under 8gb in size, make it 7gb to be safe. and the second can be any size but the machine will only allow booting from the first partition within the first 8gb of the disk. this is a limitation of the ide controller itself.

Maybe I should try that.

yes this can be buggy as hell and booting from usb1.1 is no fun... i personaly wouldnt want to try booting usb on the imac,1 .. which predates even the b+w g3s.. and everyone knows how buggy those b+w g3s are

mactrons suggestion would make more sense if it was a later version of the imac - but this is the very first one, and it wouldnt be so easy
remember its the VERY FIRST USB MAC EVER

if u didnt partition the disk under 8gb in size the last time u installed mac os 8.5 then that is why it stopped working.. either that or the disk itself died.
u could also use mactrons rescue disk to partition the disk using "Drive setup"... "drive setup" should be ablet o partition i think its tricky to do it tho u have to hold option to see the option to do it.. that is.. if "drive setup" can convert a MBR disk to APM... i think it might be able to.

if all else fails u might have to take the drive out and attach it to another mac via your USB-IDE adapter and check to see the partition scheme on the drsive and make sure its Apple partition map.

Well, now it's not working at all. It bongs, and the red light won't turn green

wait, it just shut off and won't power on again.


It's no use. I am tearing my hair out at this point, and I am ready to shelf the compy

Which would explain the issues with the CD drive, as it wasn't receiving enough power. Time to shelf the unit. I have an iBook G3 running OS9 as well as an unsupported Powerbook G4 running OS9 as well, so I guess thats how I'll get my fix from now on. My only intel Mac is a mac book on Yosemite, and my other PPC macs run MorphOS or OS9. They all work well.

I only have a full version running on my G5 tower that I fixed up, and that cost me $130 for a license for that. My Mac Mini, and my iBook G4 run the trial version which works for 30 minutes than slows down (noticeably, but not unusable).

Yeah i noticed the steep investment on the site. But they said it only runs on g4's and not even all of them. Brings a piece of the amiga back.

One way to figure if it's a G4 that'll work is if the graphics card is NVidia, it won't work. It's not really all that steep when you factor in the fact that you get free updates for the life of the machine. People who adopted MorphOS in '07 on the old Efika boards have had 7-8 years of free updates.

Personally, I use MorphOS because it's light weight on the old PPC Hardware (Very Quick Bootup), things that didn't run well in MacOS runs much better (I can run videos in 720p MKV in MorphOS which I couldn't do in OSX Leopard on my Mini). I usually run some 68k apps for productivity like wordsworth,

From what I understand, SoundBankster can be used for some DAW stuff. It is disk-jockey software, it allows mixing, syncing, tone correction, etc.

if you have a knack for programming, MorphOS is always looking for new software, namely stuff to connect it to the outside world really, support for MS office stuff is a big one. Open Office isn't on MorphOS, but someone ported it to OS/2...

we talking about nostalgia and history. Nova you might be to young for that. That time was mainly trackers, a midi candidate with a name was bars and pipes for example.

amiga sound chips aren made for that really. Btw every chip had a female name like paula the soundchip. If you look at the specs you see the limits.

i was young at the time but i was a computer user.. i was using pc's before windows 2.0 https://en.wikipedia.org/wiki/Windows_2.0 when i was just 7 years old i got my first AT computer (1984) i had a vic-20 + commodore 64, TRS-80..

tbh i wanted an amiga + atari but my dad never bought those for me unfortunately otherwise i would know all about them aswell ;0

similarly i never had a macintosh of my own as they were quite expensive.. my first mac was a performa 6400 in 1997 or so.
but i didnt use it for audio, i was into photoshop + collecting typefaces.. Adobe Type Manager etc
