Normally you should put just one terminator at each end of a SCSI bus. In this case, the other end of the bus is the internal HD (if it is still fitted), which is already terminated from the factory. SCSI being what it is, sometimes you need to break the rules to make it work. But if it works for normal storage, it should work for booting as well. - Jonathan Morton -- -- - You received this message because you are a member of the Vintage Macs group.

The SCSI ID should be set to 1 thru 6. If "reads" means the SyQuest cart mounts, then your termination should be OK. Does the SyQuest disk have a bootable system installed? Try booting without the floppy, the SE should find the bootable system on the external SyQuest drive. --glen -- -- - You received this message because you are a member of the Vintage Macs group.

Mountain Lion & Old Software
So looking through my old Mac OS Install CD-ROM's I decided I wanted to look at some old files from the old System 7 and Mac OS 8 days. I stuck the CD in the drive, clicked on a read me file and got a nice message from Finder saying "The application cannot be found." Being that it's a text file, I right clicked, tried to open with TextEdit and got another message. "The application "TextEdit" can't be opened. -108" Same message with Microsoft Word. So I thought why not copy the file to the desktop, another error "The operation can’t be completed because an unexpected error occurred (error code -8058)." Couldn't find anything about this error online either. So I went to Disk Utility and clicked Verify Disk, wouldn't you know it another error: 2013-03-16 18:28:42 -0500: Disk Utility started. 2013-03-16 18:29:00 -0500: Verifying volume “Apple Macintosh CD” 2013-03-16 18:29:00 -0500: Starting verification tool: 2013-03-16 18:29:00 -0500: Checking file system2013-03-16 18:29:01 -0500: Checking HFS volume. 2013-03-16 18:29:01 -0500: Invalid number of allocation blocks 2013-03-16 18:29:01 -0500: The volume could not be verified completely. 2013-03-16 18:29:11 -0500: Error: This disk needs to be repaired.

I've tried this with many Mac OS discs from System 7.5 to Mac OS 9.2.2 some have the problem, others don't. Seems Tiger can read them all, although Disk Utility on Tiger reports the same errors but can read and copy the files to the desktop. So my question is, would it be Mountain Lion being so new Apple just decided to take out some compatibility out of their old operating system disks & file systems? Or could it just be my machine? -- -- - You received this message because you are a member of the Vintage Macs group.

Centris 650 Power Supply
I've got a Centris 650 with PPC upgrade card that I'd had sitting in storage for about 3 years. It worked fine when I "retired" it to storage. Anyway, I pulled it out recently and fired it up and the power supply fuse blew immediately. It was loud too, sounded like a rifle being shot off in the house. I replaced the fuse, and it promptly blew immediately again as soon as I hit the power button. I figure the power supply is probably bad, so I've been looking for a replacement, but... Wow. I haven't seen a single one pop up for sale anywhere, including eBay, and unfortunately this power supply seems to be unique to the Centris 650. I have half a mind to try and fix it, so I pulled it apart and took a look at it but, aside from a layer of dust, there's nothing wrong with it that I can discern from a visual inspection. I mean, I was half expecting to see a melted transformer, burnt/exploded caps, etc. Anyone have any suggestions? Either a tip on a common failure point on these, or where I might find a replacement?

RE: Mountain Lion & Old Software
All classic support was removed when they got rid of PowerPC. System 9 and below only on G4 and older.

RE: Centris 650 Power Supply
Caps are always suspect even if they look fine, same with motherboard if it has any radials or surface mount capacitors. The centris 650 should be a pretty common power supply.

Re: Terminator for Syquest 44mb drive
Making any classic Mac disk bootable is as simple as copying a working System folder to it and ensuring it is "blessed" - showing the System folder icon with a mini Mac (not a Mac Mini) on it. Generally, simply doubleclicking a System folder then closing the window will bless it. For most removable drives, a classic Mac doesn't need a driver, as long as a Mac formatted disk is in the drive when the Mac is booted. Then disks can be changed in the removable drive (as long as that removable isn't the boot drive) during that session. If you have a blessed System folder but the Mac refuses to boot from that drive, hold Command Option Shift Delete keys, then with your third hand (or nose), poke the power button. That forces the Mac to ignore its default boot drive and scan the SCSI bus from highest ID number to lowest, booting from the first valid System folder it finds. If that doesn't work, hold Command Option Shift Delete and the number key (top row, not number pad) corresponding to the SCSI ID you want to boot from. (Might have to use a foot to poke the power button...) You have to hold all those keys until you get the startup sound, indicating it's passed the hardware self tests and is beginning the bootup process. -- -- - You received this message because you are a member of the Vintage Macs group.
