Trying to find Mac OS 7.6 (7.6.1) is ridiculous.

I can imagine. Why not just go for 8.1?

Anyway the keyboard lights up at boot but does nothing after that.

I'm not clear if you mean you can't get the keyboard to do anything at all, or if you just can't get it to boot from the CD drive.

I have a bootable CD in the tray.

It's not one you made yourself, is it?

The power button on the keyboard does nothing either and i have to turn on by pressing in the switch at the back instead.

Is the internal clock still keeping time? Sometimes when the internal BIOS battery starts to die, using the switch at the back is the only way to get anywhere. (They're not very common batteries, unfortunately - half-size AA's.) Or can you not even get that far?

I bought an 80 pin SCSI hard drive and convertor to use on the mac

So, SCSI-III, then? Working with SCSI is always a "delight".

Another problem i have is trying to get the monitor to work with other computers, i have 2 convertors to HD15 (VGA) and they give me what i think is a sync issue. The Colour Display is 640x480 (35 kHz Horiz. Scan, 66.7 Hz Vert. Scan). I knew i was better off buying a VGA monitor and using that with the Mac.

What makes you think it is a sync issue?

All of the adapters I've ever seen tend to have DIP switches to let you set the output resolution.

Augh! Please do not put images directly into your post if you're going to use such a high resolution!

The reason i don't want to go for 8.1 is the slightly increased resources and the fact im only going to do light gaming and some messing around with the Mac.

Seems like a lot of trouble to go through to avoid "slightly increased resoruces".

The keyboard does nothing, i would assume that caps lock would light up IF the board was working regardless of where it was at desktop or not. It simply flash all the LEDs and then does nothing at the "no boot" screen.

I'm still confused. Can you get past the "no boot" screen at all?

Apple Legacy Software Recovery CD and it should boot into Mac OS.

I'll admit I don't know too much about booting from CDs on an old Mac. Are you sure the Quardra 650 has that capability?

Can you use the System 7.5 Network Access floppy disk? You should be able to write that to a floppy even using a PC.

YUP that SCSI is Apples stupid 50pin! 50pin is VERY difficult to get hold of these days even then its usually expensive. AS LONG as the drive terminates it should work when its formated to work as an Apple drive.

What surprises me is that you found an 80-pin to 50-pin adapter that was able to fit in the "pizza box". It's not actually a 68-pin, is it? (The 80-pin adapter has a molex connector for power.)

Then i bought this adapter with dip switches and a gender changer, like so. Same issue as before.

Have you found a guide for the DIP switches? Obviously, if they are not set correctly, there may be problems. I'm not sure those adapters work bi-directionally, though – in fact, it would kind of surprise me if they do.

Yeah it can boot from CD, you hold C at boot up. I get this screen but with a flashing ? in the middle, eg. it cannot find any boot media. The keyboard like i said just flashed as soon as i've turned on the Mac but it doesnt do anything like i should be able to hold in C or some other commands at bootup.

You are not answering the question. Have you been able to get past the "no boot" screen at all? I'm just rather skeptical that it is safe to conclude at this point that the keyboard is not working from the available data.

Could you please go back and replace the in-line images in your earlier post with links? This thread is very hard to read.

You should use HFV Explorer for writing Macintosh images in the future. It is free and works everywhere.

http://www.emaculation.com has some excellent information on setting up Macintosh emulators. (By the way, TOS rom files are for Atari ST emulation.)

Does your Mac not have ethernet? It is quite possible to get a Macintosh communicating over the network with Basilisk II or Sheepshaver, except of course the network driver won't work in 64-bit Windows.

Can you see the hard drive on your Macintosh after booting with the network access floppy?

x

Then it would seem you also cannot conclude that the hard drive is working correctly. Can you hear or feel the hard drive spinning up? Were you using it in a different machine before you installed it in this one?

You have to know how to set the DIP switches for the screen resolution you want to use. Unfortunately, a lot of those adapters that are being sold used have been separated from their instruction manuals for a long time. Unless you can figure out what brand of adapter you have and find a manual online, you'll have to trial and error it until you get a picture and with that many switches to set it will take a long time.

Oh, and on a Quadra, 8.1 isn't that bad. I upgraded from 7.6.1 to 8.1 on my 840AV and there was no performance hit at all. I also have a Frankenmac I built with a Quadra 700 motherboard mounted in a IIvx case with the PowerPC upgrade board installed and that runs 8.1 just fine in both 040 and PPC modes and I believe the 040 in that machine is slower than the one in the 650.

The hard drive could very well have some sort of termination issue, surely?

I set the adapter to ID3 and the HDD to ID3

SCSI devices need a unique ID on the chain. If two devices have the same ID they won't work.

Edit: Ah you got it. Nevermind this then. 😀

The HDD is a Seagate ST318404LC. Without the HDD the CD drive will open and close, but i think without termination it wont load or be recognised by the OS properly.

Is it an Apple branded drive? Apple's disk utility won't recognise it if it's not. You'll need a patched version of the Apple disk, or a third party one.

I'm just going to leave this here:

Also things i've learned about 68K macs:

1: by default, the installer will only install to apple branded drives
2: the mac OS has problems with drives over 2gb in size.
3: Unless there is something you NEED in the newer versions, stick with the version the machine shipped with.
4: Invest in TWO zip drives. 1 scsi for the mac, 1 usb for your main computer. Also google transmac software.

That is precisely what Mr. Kieran has been attempting to use.
