You should see 7.5 V DC output at the tip (centre-positive). The power adapter may not be warm unless a certain amount of power is used by the computer. 2.0 A maximum output current power adapters should be OK, but a 3.0 A model (intended for the 180c) will work as well. It may also be worth...

A CompactFlash memory card and a PC Card adapter for CF in the PowerBook, as suggested by LaPorta, is the way I would use in a similar case. If necessary, the card can be PC-formatted (FAT). With an appropriate Ethernet PC Card, or an Orinoco Silver or Gold Wi-Fi PC card (with the thick...

Furthermore, IF it turns out that your Sony hard drive in fact is OK, would it be correct to assume that you have seen https://68kmla.org/bb/index.php?threads/se-30-cant-recognize-scsi-hdd.33956/ about a (solved) SE/30 logic board problem?

Different connector/jumper names/numbers appear to be used on different web sites. Should it be J6 with pins 9-10 connected??? To be double-checked. However, the idea would be to determine whether the Maxtor drive is set to automatically begin spinning when power is applied. Could it be...

Found wiki.preterhuman.net/Maxtor_LXT213SY via a web search. Would this possibly be of any help at all regarding jumpers et cetera for the other hard drive (the one that is not spinning at this point)?

Glad to hear that the floppies arrived safely. Sometimes, an already existing bad SCSI hard disk driver can be prevented from loading by holding down the four keys Command(Apple) + Option(Alt) + Shift + Delete(Backspace) when starting the computer. That may not change anything here, though. If...

mikes-macs kindly offered to create a floppy disk. If necessary, and if the normal approx. 2-5 days letter delivery time within the EU is acceptable/faster, I would also be glad to help you. If so, just send me a direct message with your address.

The German site http://www.knubbelmac.de/ is using plain http and thus even accessible from a System 7.x Mac running the WannaBe web browser (or something similar). Under Software -> Werkzeuge you will find several utilities. If necessary, use a web page translation service. Remember, do not...

It is not unusual to find that Apple HD SC Setup cannot properly locate/recognise/initialise a SCSI drive that previously had been (re)formatted with a non-Apple utility. If so, you could try something like Lido 7.56. One problem (if you do not have access to a fully working Mac with a hard...

A wireless Ethernet bridge device connected to the Ethernet port of the Quicksilver computer could be one way to solve a problem like that. This could be a Wi-Fi range extender with Ethernet capabilities operating in a client/adapter/bridge mode (Edimax EW-7438RPn Mini is just one example)...

A Network Access Disk 7.5 can be quite useful for general startup purposes. (http://download.info.apple.com/Apple_Support_Area/Apple_Software_Updates/English-North_American/Macintosh/Utilities/Network_Access_Disk_7.5.sea.bin)...

For safety reasons, rebuilding a power adapter would not be my first choice. If you so wish, a good quality universal power adapter with a 24 V DC output at 2 A with an appropriate connector (barrel type with centre +) could be an alternative.

Could a good universal power adapter (including 24 V DC at 2 A) with a normal barrel connector, combined with a special tip adapter piece like the www.bixpower.com/CNT-C11-p/cnt-c11.htm (I have not tested this one), possibly be an alternative?

You may have seen this already, but any details of interest on page 11 (Hard disks) in the following user's guide? download.info.apple.com/Apple_Support_Area/Manuals/powerbooks/0307136APBDUODOCUG.PDF

Yes, keyboard problems were mentioned, for example, in the following 1994 FAQ: https://websites.umich.edu/~archive/mac/util/powerbook/duofaq.txt
