[Apologies to those who who have seen this before] Has anyone out there ever used an ST as a file server for an 8bit machine? I would like to keep all my 8bit stuff on ST disks. A 'get' type command given on the 8bit would then cause the ST to send over the file needed (via a joystick port?). This would mean that an ST hard drive could be used in the same way. Is there any code available to do this? If so, can it be done without the ST user being aware of what is going on (or at least without disturbing any program running on an ST). I would think that any routine to do this would have to be interrupt driven. The ST watches for the 'get' signal during a VBI. When it arrives, an interrupt is generated on the ST. The ST procedes with the request using the VBI to send blocks of data over. Any program running on the ST is only frozen during disk access. Is my thinking correct?

There has already been a program/cable between the two machines via the rs232. I think one possibility could be the midi ports. If they could be reduced to 19.2Kbaud and connected to the 8-bit serial port, they could emulate one helluva drive. BTW, this is a takeoff on Bits and Peices from ANALOG, where they are telling how to turn an 8-bit into a printer buffer for an 8-bit. imagine... :drive 1: :modem:->-:bbs: :plotter off R2: | | | :800:-+---------+----------------+----user 1 | | | | :?: :400 Pbuff:---+--+--+--user 3 | | :drives galore: :?: | | | :st Drive 2:-+------------------+-----------user 2 | :modem:->-:unix system: /\ ___ ___ /\ John Kawakami c60b-at@buddy.berkeley.edu \| o|/\| o|/ "Shouldn't we read the instructions?" -Hobbes |___| |___| "Do I look like a sissy?" -Calvin
