Unless they used some special Shiva only adaptor (which is HIGHLY doubtful), then yes, you can make that assumption. There were only two styles of Localtalk connectors for connecting to computers, the DE-9 (used by old Macs, PCs, repeaters, and hubs/routers/bridges) and the mini-din 8 (used by most Macs, printers, and some hubs/routers/bridges). In both cases, the pinout was a standard, so if you can find the pinouts for the mac's din 8 serial port and the old mac's DE9 serial port, it should be trivial to make up an adaptor. -chris <http://www.mythtech.net>
