And here is some additional information regarding the update procedure of Mac OS 9 on a PPC with Sonnet G3 upgrade (here: PM 7200), I stumbled across the following text clip that was copied from another forum a couple of years ago. I can not confirm the suggested update path to be successful...

A hardware handshake null modem cable and a terminal programme on each end should do well for file transfer. More convenience you can have with applications like Stargate, providing drag and drop file transfer in watched folders (Mac and PC Freeware available, Linux support unknown). It works...

Please look for null modem cable pinout at http://lam.kilu.de/ → LAM → Nullmodemkabel (great resource, in German language, but the schematics are self explanatory).

A major reason to keep a beige G3 operational might be to have a unit that will be able connect to nearly any other computer Apple made. It may sport RS422, ADB, USB, FireWire, SCSI, IDE, SATA, Ethernet, audio and video in and out, internal ZIP drive, Floppy Disk, CD/DVD read and write...

Once I had the same issue with another PowerBook G4. The fan activity became annoying, thus I decided to dismantle and reassemble the heat pipe and fan assembly. The black thermal glue used in the manufacturing process is quite difficult to remove. To avoid any shorts caused by newly applied...

Consider to additionally look for a FW/USB combo card (like OrangeMicro) and FastEthernet card (any cheap PCI-card with RTL8139x chip should do). The inbuilt FloppyDisk drive will not be usable with 10.2. If FD support is needed, look for an Imation SuperDisk USB version, that could be...

The PB1400 as well as the PM7200 with Sonnet G3 upgrade are limited to stay with System software versions below 9.2.2, because the necessary Sonnet Extension lacks support for newer Systems than version 9.1. I found no way to work around this except of checking portions of the 9.2.2 installation...

A cheap and convenient replacement for the PRAM battery is a standard battery holder, like for AA or AAA size cells. There are some threads regarding the PRAM batteries for desktop Macs. PowerBooks have similar requirements, only less space available inside the case. Just check for the voltage...

When the Performa / LC 475 was new I followed news regarding L2 cache cards to accelerate the machine. My impression was that general stability issues were the price to pay for some performance gain, no matter which make of L2 cache you purchased. As far as I understand the software was not...

For the sense pin and extented sense pin codes visit http://lam.kilu.de/lam2/sense.htm, please. To make any supported display resolution available in System 7.1 (and probably some other System versions), use "Activate all Resolutions", an extension which permits to access any resolution by the...

An appropriate and affordable solution is a PCMCIA to SDHC Adaptor and an SD-Card with a storage capacity of 4 GB (common, cheap size; more would violate the 4 GB-limit with regard to SCSI target mode). Consider to search the board and our Wiki for addtional information. Some equipment might not...

On some kinds of plastics silicone oil does support a nice look without doing harm to the structure. It is known and used for the effect to avoid anything else to adhere to the surface covered with silicone oil. However, some plastics might be damaged severely. In any case silicone oil turns out...

Thank you for this extensive explanation on Pledge, Armor All etc.! Years ago I found Silicone Oil being a main ingedient of such mixtures. As I learned in materials science, silicone oil can severely harm the durability of many plastics. The tensile strength of silicone treated fabrics like...

If someone only needs quick and dirty solutions for some tasks to automate: AppleScript, KeyQuencer, Folder Watcher and Okey Dokey make an excellent combo to let the Mac do some stuff unattended that usually needs user interaction. KeyQuencer can wait for some specific window to come to front...

What you ask for is exactly what is implemented in the OSAX (AppleScript extension) suggested by Bunsen or in the XFCN from the Dartmouth HyperCard stack. The source code is written in C or Pascal but might be difficult to obtain. Consider to get a copy of the Mac Programmer's Cookbook. This...

In the Dartmouth collection of XFNC / XCMD code also some similar thing is available: Look for "SerialHandler". However, some system software extension might need to be removed. As far as I remember it is called "Serial (Port) Arbitrator" which causes SerialHandler not to work. Unfortunately I...

:)

A behaviour according to existing standards would be most preferable, like firstly check for some Alt-key depressed to invoke a custom boot drive selection and (if that is not the case) secondly look up boot disk settings stored in PRAM. Probably one could allow to optionally directly address a...

Now that there can anything be preinstalled on that ROM, including the set up of a RAM disk with preconfigured contents, one could automate any task that formerly was doable with a warm restart, only. Hwo fast it works! Think of custom drivers for peripherals to boot from alternativley, like...

Since I started to use CompactFlash cards with a PCMCIA adaptor in a PB1400 some years ago, I use CF and SD cards with adapters and card readers as a preferred removable media on any kind of computer. For old Macintosh computers I use an Adtron PCMCIA card reader in an external SCSI enclosure...
