The easiest way to handle the hardware (and probably the fastest) is to use SCSI controllers in each machine. One will act as the 'master' computer, with up to 7 "slaves". All you need to do is change the SCSI ID of each of the slave controllers. The controller defaults to ID=7, but it can be changed. Since ID7 has the highest priority in a SCSI bus, that should be the master, with the slaves on ID's 0-6. If there is enough work to distribute, you could even put multiple SCSI cards in the master and have it control multiple groups of slaves.
It may not be the cheapest method, but it will almost certainly be easiest. If they are high-speed SCSI cards that use DMA transfers, it will also be the fastest way of moving data between Apple //'s Geoff ----- Original Message ----- From: "Jennifer Worgan" <[EMAIL PROTECTED]> To: "Apple2list" <[EMAIL PROTECTED]> Sent: Wednesday, November 10, 2004 06:46 PM Subject: Re: question for the experts > I am wanting to use an Apple IIe as a primary computer to program to > evaluate problems/tasks and then route them for actual processing as > subroutines to other Apple IIes, then collecting the finished result from > the other Apple IIes and integrating them and processing their results in a > final problem/task. > > Example: entering an equation, analyzing it for subroutines/processes, > sending those to different Apple IIes for processing and then entering the > results back into the original equation for solution. > > Can this be done though the disk drive connections connecting Apple IIes to > each other rather than to disk drives, connecting 2 Apple IIes to the main > Apple IIe, and additional two to each of those two, etc. > > I know it would require writing a program to replace DOS which would > transmit data to the secondary tier of Apple IIes and would read data > transmitted back.
