Dear Netters, Has anyone got the specs for the DMA port yet? If so where did you get the information? Has anyone verified that there is an easy way to convert it to SCSI? Yes, I have the January Byte. Please post or mail according to your feeling about general interest in your information.

Since the dma port is the only high-bandwidth port on the machine a detailed description of it seems necessary. The rom port has no read write line so it's useless for this and I think the moral to the MAC's "serial is all we need" philosophy should be obvious by now. It all hinges on how general the data that can be sent from the dma controller is. I sure hope that one can use this port in a general purpose way and not just in disk-like protocol. If I can't I probably won't buy one. Who knows how the port-dma controller work? The information in the BYTE article gives no clues. -- Andrew Voelkel {ucbvax,ihnp4,akgua,hplabs,sdcsvax}!sdcarl!andy
