I am a complete novice as far as hardware goes. Does the CoCo have the capability to support DMA devices? I have heard that some micro implementations cannot use DMA because of inherent design decisions (like, low cost.) Is this true for the CoCo? Would microsoft!danm who is writing the OS-9 device driver for the unspecified hard disk care to comment on its DMA capability? /Steve Dyer decvax!bbncca!sdyer

If Radio Shack would have run the BA BS line out of the slot, DMA could have been done by using the HALT- HALT ACKNOWLEDGE handshake from the 6809E (I guess that the two line could be routed "over the top" with some sort of connecter on it). Mark Pease tektronix!tekig!tekig1!markp
