My first task will be a hard drive upgrade. I was planning to replace the original 40m drive with an APS 1g external SCSI (removed from the case) I have laying around. Trouble is, I don't know if the speed of the 1g drive will be too fast for the SE to support. I've heard that the maximum for the SE is around 5400 revs. Any truth to this? I don't even know how fast the 1g spins. Any idea on how I can determine this? The original manuals are long gone and the drive is long out of date with APS.

Alternatively, I have a 160m drive from an old IIcx that is an option. I know that this drive doesn't spin too fast for the SE, but I want to use the 1g drive in the SE!!!

Can I get away with using the 1g? I want the SE to smoke, but not literally.

After that, in go a superdrive floppy, modem and CD slot loader. After that, a serious custom case hack and paint job.

Anyway, have fun!

I thought about replacing the SE board with an SE/30 board. Since I haven't had much luck finding the board, I got to thinking: what about the LC and Performa boards that Colour Classic hackers use for Mystic and Takki upgrades? There seem to be lots of these floating around -- and affordable too. Will any of these boards fit the SE, which is comparable in size to the CC? Obviously, the colour option on the board is out, but there are so many other benefits that it doesn't matter. Could it work (without a hacksaw)?

It's interesting, but it's a lot of work. I've done something similar to what Stuart describes, putting the guts of an Apple 13" high-res monitor into a Color Classic and hooking up a 6360 motherboard to it. It works, but it's not as elegant a solution as a regular Takky.

Permanent 68k roommates:

- "Mystic" Color Classic, full '040, 36/700/enet, OS 8.1

I checked out Bell's project and that's a lot of work for someone who doesn't have a deathwish. I'll have to stick with what I've got. Thanks for the link.

one way to make logs get bigger would be to run MySQL and PHP and put a forum on there (just my 2¢)

I'll try to keep the floppy drive in if I can get all three drives to stack on top of each other (HD, floppy, cd). Thing is, the floppy is 800k, and if I can't find those three chips that allow the SE to read 1.4 flops then I'm gonna take it out (I have an external FDHD I can use when needed). On the subject, does the Classic use those three chips in order to run a Superdrive? I've got a spare Classic that reads 1.4 flops, and I'm wondering if I can scavage the chips from it and put them in the SE.

Honestly, I would perform all these hacks on the Classic, since it's a much more attractive box then the SE (I think). The determining factor is the Classic's viewable screen, which is much smaller than the SE because of those half-inch dark borders on the top and bottom of the screen -- know what I mean? I thought it was just my Classic at first, but every Classic I've seen has that irritatingly reduced viewable screen. Shame.

Yes yes yes(2)! A try on the Classic screen fix is in order. Thanks for the tip on Gamba. But I have never been able to access Gamba. I always get the message from Earthlink that the site has exceeded its allowable usage quota. Any workaround here?

Well, if you can ever get it to work, I'd be mighty glad to get it. Same thing for anyone else who could get me the service manual online. Thanks.

Good luck, and have fun!

Thanks for the page. I'll try the fix tonight.

I'm just about to swap the Classic's 80m HD for a 1g HD, but for one concern: I know the Classic will support the 5400 revs of the new drive, but what's the worst that can happen if it proves too burdensome for the old Mac? A burnt power supply? Something easily replaceable, right? I do have a spare 160m...

When I switch the Classic on, the HD clicks about 3 times before for the question-floppy comes up. Any idea of what's going on?

The pwer required to run the former drive (80m Quantum ProDrive ELS) is 5/12V. I don't know about the newer drive. Don't think 5/12V is enough to run a 1g drive?

What about this: the 1g came out of an external setup. Before removing, I clicked the manual SCSI address to 0, so it would run as the default drive in the Classic. Could this be the (a) problem?

5/12V is always the same, you should take a look at the "mA" numbers. :-)
I think these figures are while the drive is running, it might need more power to actually start spinning. And a newer, faster drive would probably need more power to start than a slower one?

The old drive from the Classic had a 230/230 mA.

As an earlier poster said, you need to look at the current required by the drive, not the voltage. Nearly all drives need 5 and 12 volts (5 for the logic, 12 for the motor). The key is to see how much *current* the HD draws from those supplies.

If it turns out that you do need a stronger supply, there is room to shoehorn a small additional power supply. I've done that before (for a Plus hack), and it works great.

Could the problem be that I did all the initializing and software installation (OS 7.5.5) on the two problematic HDs from my PowerMac 7500/G3? Would this matter?

Here's something: for fun (ha) I stuck a spare Quantum 160m drive into the Classic and tried it out. It has the exact same power specs as the 80m I took out -- and it does the same thing that the 1g drive is doing. It clicks and starts spinning, and then the Classic tells me it can't find a startup disk. When I boot it with disk tools, it still can't see the drive. I get the message: no suitable drive connected to SCSI.

Both the 160m and the 1g drives were removed from external boxes, where they worked fine -- until they were put in the Classic.

The old 80m Quantum drive I took out of the Classic didn't have any (obvious) jumper caps where they would normally be (that I could swipe for the new drive), so perhaps it has some other type of self-termination enabled?

I've finally found a jumper clip and terminated the Quantum 1g as per recommendation (on the TE pins).

The Classic now starts up, spins the drive, and no longer brings up the 'can't find startup disk' icon. Instead, it brings up...

A dead Mac with the traditional two lines of code beneath!

Any ideas about this new revoltin' development?

Before I removed them, I set their manual SCSI addresses (i.e., that little address switch on the back of the boxes) to 0. What do I need to do to terminate them?

This could be a problem, that is, unless you also removed and left the ID switchblock/cable assemblies connected to the drives. When you removed the drives, you probably also removed the SCSI address setting of 0 and they're set to whatever the default with none of the jumper pairs shorted happens to be. If the default is 7, that could be your problem, time to check the docs again!

Try booting off of a floppy. If that works, then update the driver (or reformat/reinstall, etc.)
