Someone made a video of a 5 1/4 inch 88 MB Syquest drive with the metal cover of the drive removed The 5 1/4 inch 44 MB Syquest drive sounds the same.

I don’t think you can lump all PowerPC Macs in the same category. Some G3 and G4 Macs are still working fine.

Oh well, hope you can get the computer fixed because it’s a rare model that was only sold in Japan.

The ZuluSCSI RP2040 and the ZuluSCSI Compact RP2040 have a spot where you can solder a Piezo for simulated HD sounds

Syquest 44 MB removable hard drives are pretty inexpensive and have a long life reputation, as long as the carts are not mishandled or stored at extreme temps.

Try pressing and holding the c key on boot up, to force booting from the CD

Some Macs of that era will not boot properly without the 3.6V PRAM battery installed. Also you may try resetting the PRAM by holding down the Command Option P R keys just after switching on the power. Hold the keys down until you hear the bong sound and repeat.

The BlueSCSI appears to be working properly. Do you have another external SCSI drive you can temporarily attach to the computer, to confirm the SCSI port is operating?

The Radius 81/110 specs are nearly identical, but it has a full metal case.

I’d guess Microsoft never tested that version of Office on a Mac IIfx running OS8.1. Maybe you should revert to an official MacOS release for more reliable results.

According to Apple, the last supported OS for the MacIIfx was 7.6.1

On boards with surface mount components on two sides, the components must be placed and soldered one side at a time. Typically the less complex side is placed and soldered first (bottom side in this case), then the board is flipped over and the more complex side is placed and soldered (top...

bigmessowires, The straight thru serial cable is likely meant to be used with a manual switch box such as https://www.cablesdirect.com/store/p/2250.aspx

ZuluSCSI works great - I wouldn’t mess with spinning SCSI hard drives again, unless it was a removable cartridge drive.

Is the Ethernet chip clocked off the CPU crystal Q650? On the C610 it is, and overclocking the CPU will make Ethernet unstable.

You can connect the ZuluSCSI to the external port with a SCSI adapter such as the https://store.rabbitholecomputing.com/product-p/idc50f-db25f.htm and place it in a small case.

PowerBooks were too expensive for schools, but an LC with attached screen would probably be far less expensive. Too bad Apple never built it.

Glad you are making progress. If you have a SCSI external case, you can plug the ZuluSCSI in the case and connect it to the external SCSI port

Maybe I was jumping the gun. What exactly does non-working mean? Does you computer see the hard drive after booting up? Does SCSIProbe see the drive? Do you have a boot floppy in the drive or another hard drive attached to the computer?
