Geo,

To clarify some things:

- Mode32 is a System Extension file, meaning that it is like a .dll file under Windows. The file is designed to "patch" a Mac that was "crippled" with 24-bit addressing. The architecture is 32-bit, but for some reason, Apple released the model as 24-bit addressing. Without that Mode32, or equivalent, the Mac won't address anything higher than 8 megabytes of RAM. The system was addressing 24-bits and Mode32 patches in that missing 8 bits of code.

- There does exist a BASIC interpreter for the Mac called Chipmunk BASIC. It is compatible with QBASIC, QuickBASIC and Microsoft BASIC languages. It even includes a built-in conversion to Pascal and Assembly code languages, IIRC.

- Asante makes both a SCSI to Ethernet adapter and LocalTalk to Ethernet adapter. LocalTalk is the 8-pin jack(s) on the back of each Mac. You will need either adapter to translate Ethernet to an older Mac. You will be able to file share, Internet access and send documents to a printer on an ethernet network.

- You can use either the LocalTalk or SCSI ports to send and receive special hardware controls on projects. I'm not familiar with how exactly to do so on SCSI, but with LocalTalk, you'll be having better luck overall. The LocalTalk Modem port is a serial port (RS-422) and you'd be sending that type of level of control on the projects. I can assume that compatibility is more supported via serial verses SCSI.

- It's hard to say what largest SCSI drive you can use on an SE/30, but just remember that System software from 6 through 7.5.5 doesn't recognize HFS+ or HFS Extended partitions. That didn't become available until Mac OS 8.x. If you do put a rather big, several gigabytes sized drive inside, be sure to create each partition to have up to 2 gigabytes size. HFS only allows that to be the maximum size to natively support.

- If you do install 64 megabytes or more in your SE/30, be prepared to wait awhile for the RAM test on first power up to finish. This is only when you power on the Mac from a cold boot.

- Some model printers may need to support AppleTalk as well as PostScript to work with Macs on a network.
