Scsi2sd powerbook

RSS Feed. The hard drive in my Mac SE is on the way out. Sometimes the drive is detected, sometimes it's not. Sometimes the SE boots all the way to the Finder without a problem. Sometimes it hangs at the "Welcome to Macintosh" screen. Sometimes I can launch an app and run it without issue, but then the whole machine hangs when I exit the app.

It's been like that for about months now, and it seems to be getting worse.

(Trying to) Revive a Mac SE/30

It's only a matter of time before the drive completely dies. Luckily, I have an external drive that I copy of all my apps, files, and disk images to for redundancy.

Unfortunately, that drive is starting to flake out too. It's more reliable than the internal drive, but it too sometimes doesn't appear in the Finder at startup. Then again, I don't know if that drive is having issues of its own, or if the internal drive is wreaking havoc on the SCSI bus.

I've really been wanting to get away from old spinning platter based drives for a while now. They're just getting too expensive.

I've seen a few solid state alternatives online before, although they've been too expensive for me to take the plunge. Unfortunately, me actually having the money and them being available on eBay was never at the same time. I figured I'd get through the holidays first, and then pick one up. Well, it's already February, so I figured I'd get one now since the drive is really starting to act up. This thing is amazing!

It looks simple enough. There's power management stuff on the right, a single chip in the middle that does the talking, and an SD card interface on the left. I'm no stranger to Arduino buildsand this doesn't look any more complicated that the likes of my GPS clock, or any of my clocks for that matter.

Then again, perhaps the firmware on that chip requires nothing short of witchcraft. See, this is why you shouldn't throw anything away!

Myself, if I had a board with that much damage, I would give up and donate it to science. But my threshold for pain is low. I really enjoy his videos and come away with learning many new things.

Don't we have all that on the Bomarc schematic? Gotta get that one to see if it has the info missing from Apple's. Did you replace the capacitors on the logic board? And what about the CMOS battery? That needs to get replaced too Sign In Sign Up.Options for more recent machines are covered in PCI and Cardbus drive controllers. The majority use SCSI drives of a kind no longer in production; either 50 pin 3. There are several replacement options for defective SCSI drives.

Even with a working SCSI boot drive, a second drive for extra storage is often desirable. The choice depends on the expected use of the device, and the performance required. Note that the throughput of a faster, more modern drive is usually throttled by the slow SCSI speed on the Mac itself. Unless you are using a high-performance drive controllerit will still be limited to the host Mac's speed. The simplest solution of course is another 50 pin SCSI drive.

Typically these are older drives now, and limited to around 4. They may also be loud and hot server drives. However they have the advantage of plugging straight in to all 68k Macs except the Powerbooks, space permitting.

Using a SCSI2SD adapter to setup your 68k Macintosh

Note that there are two versions of the 50 pin connector, large and small. Macs use the larger of the two. A simple socket adapter is all that is required. An adapter from 68 or 80 pin to 50 pin, or a SCSI cardis required. These are usually server drives: they can be noisy, but offer relatively large capacities, high performance and reliability.

One will also usually need to terminate the top 8 bits of the 16 bit SCSI channel: converters with termination resistors are available, or they may be added by the user.

While 2. These are available for single drives, pairs, and multiples of 7, 14 and so on. With a long enough cable, the enclosure can be hidden in a place where noise can be contained. An external drive can still be used as a boot drive, and the enclosure can easily be unplugged and connected to different Macs, including Powerbooks. Some host 68 or 80 pin drives internally, yet interface to the host with a 50 pin cable.So, similar to my entry on setting up using a floppy diskand setting up using an Iomega Zip DriveI created boot images for System 6.

Note, this is one of many, many options available to you for booting your classic Macintosh. These three 68k systems do not support internal or external SCSI. Remember to write the configuration information down. If you used option 3.

If you plan to use any System older than System 7. Thanks to Huxley Dunsany for pointing out the settings, and James Thomson for confirming they worked on a 2nd system. This will let you create a SCSI 0 boot drive partitioned exactly how you want.

Hello, I just did this using Mac OS Thank you very much! I should mention that dd took quite a while for me, around 3 hours. Odd, the zip files were made by me and have been scanned by BitDefender. Just our if curiosity, once this is set up, is there a way to write additional software to the SD card?

The easiest way would be to edit the image before you put it on your card. If you want to edit your card later, you can create a new image based on card. I have the 5.

Which firmware version s have you been successful with? Hi Steve — would this work with a color classic with an LC board? Would I be able to do an external install or would I be better off with an internal install for this configuration? If so it should see your CC as an LC and work.

For internal vs. Thanks for these guides, it was a great and complete set. It seems quite complete. Two questions:. How can I achieve this? Hi Daniel, 1. You can write one of my images to the first part of your SD card, then set up the remaining parts of the card as additional drives following the instructions in section 3.

If you replace the few electrolytic capacitors in a Powerbook with long-lasting ceramic or tantalum capacitors, the Powerbook will be a valuable reminder of the 90s. The software might have been tested with your specific device, see the list at. Please note that this version for Apple Powerbooks is fitted with a connector for Powerbooks, the common 50pin SCSI connector not contained in kit would have to be connected manually by wires. Same with the power input.

Jurisdiction of a court is excluded.The first bit of "advice" drives me up the wall because while it's true for many Macs, it's now uttered in almost a knee-jerk fashion anywhere almost any vintage computer is mentioned this kind of mindlessness infests pinball machine restoration as well. To be sure, in my experience based Macs and some of the surrounding years will almost invariably need a recap. But this is probably not true for many other systems. Many capacitors have finite lifetimes but good quality components can function for rather long periods especially with regular periodic use; in particular, early microcomputers from the pre-surface mount era including early Macs only infrequently need capacitor replacement.

Similarly, newer Macs, even many beige Power Macs, still have long enough residual capacitor lifespan that caps are at least presently very unlikely to be the problem, and trying to replace them runs you a greater risk of damaging the logic board than actually fixing anything the capacitor plague of the early s notwithstanding.

Unlike capacitors, this suggestion has much better evidence to support it as a general recommendation as indicated by the SCSI2SD's rather long list of reported working hardware V5 device compatibilityV6 device compatibility. However, one thing that isn't listed much on those pages is whether the functionality is still the same for other OSes these computers might run.

That will become relevant in a moment. The jury is still out on whether the ThinkPad's components were iffy to begin with or the SCSI2SD was defective, but the card went to the recycler regardless since I wasn't willing to test it on anything else. Although current versions of the OS apparently continue to support itI had problems even as early as 1.

However, none of the essential additional software packages such as netatalk are available anywhere obvious for this version, so rebuilding from scratch would be impossible; instead, a full-system network backup runs at regular intervals to archive the entire contents of the OS, which I can restore to the system from one of the other machines see below.

It has run nearly non-stop since Here it is in the server room: In it finally blew its caps and needed a logic board refurbishment the L1 card was recapped at the same time. Its hard disk has long been marginal and the spare identical drive had nearly as many hours of service time. Rotating between the two drives and blacklisting the bad sectors as they appeared was obviously only a temporary solution.

SCSI hard disk replacement options

Though my intent was to run the drive s completely into the ground before replacing them, bizarre errors like corrupt symbols not being found in libc. Last week half of the house wasn't working because nothing could get a DHCP lease.

I looked on the console and saw this: The backup server had a mangled full system tar backup on it that was only half-completed and timestamped around the time the machine had kernel-panicked, implying the machine freaked out while streaming the backup to the network.

This strongly suggested the hard disk had seized up at some point during the process. After I did some hardware confidence testing with Snooper and Farallon's diagnostics suite, I concluded that the RAM, cache, CPU, network card and logic board were fine and the hard disk was the only problem. I briefly considered moving services to the RaQ, but pretty much nothing could replace this machine for offering AppleShare services and I still have many old Mac clients in the house that can only talk to thuleso I chose to reconstruct it.

While it still came up in the System 7. I tried all of these steps on the v5 and most of them on the v6, both with up-to-date firmware, and at least a couple iterations with different SD media. Here goes. First attempt: I set up the Q to run a block-level restore from an earlier block-level image. Assuming this worked, the next step would have been overlaying the image with changed files from the last good tar backup. After suppressing the urge to find my ball-peen hammer, I decided to reconfigure the SCSI2SD with the geometry from the Quantum Fireball drive it was replacing and it accepted that.

I then connected it to the Q and restored the files from the last good tar backup to the NetBSD partition. It mounted, unmounted and fsck ed fine.NOTE: Unless noted otherwise, descriptions herein refer to features of firmware version 4.

Using a SCSI2SD adapter to setup your 68k Macintosh

This usually happens by mistake when people make custom power cables for use in samplers without standard drive molex connections. It's very easy to switch the positions of the 5V and 12V wires.

If you do supply more than 5V, a new hole will appear in the main chip Cypress PSoC 5lp and the magic smoke will escape. Due to the more efficient power supply switching regulator as opposed to linear reegulator USB power is sufficient to run run the terminator.

When re-inserting the resistor packs, be sure to align the printed dot on the resistors with the board markings. Most SCSI host controllers provide the power required to run the terminators via the pin cable. Providing termination power via J3 only works when powered via a standard disk drive power connector. Use whatever is convenient. Since the procedure for upgrading firmware above begins that way, the default configuration values may be seen in the picture above. In many cases, the default configuration on the board will work "out of the box", but it may not be optimal in your case.

NOTE: At the moment through firmware 4. There is, thus, no removable-card-specific configuation. Jump to: navigationsearch. Personal tools Log in.
