2525.0. "Disk I/F using PARALLEL" by VIVIAN::S_GOLDSTEIN (Steve G.. Tel 01-234-5935) Wed May 03 1989 06:02

	Hi Guys,
	       Has any one heard of M.A.S.T's PARALLEL PORT SCSI/DISK
interface ?
	 I phone them up and they said that it works just as well as the
EXPANSION Port types BUT you can have a longer lead. It has PASS THRU for a
printer and can control up to seven drives.
	They quote it as having 2.5 MEG/sec Transfer rate.They use Segate
drive units 3.5" size and they are working on a DMA type.

	Does anybody have a list of the different HD controllers wheather they
are DMA or not for the AMY 500/1000/2000 ?
	I'm still trying to find the cheapest way to connect up my AMY 500 with 
a disk drive and possible extra memory (I already have 1 MEG. A500+A501)
			Thanks for any help

2525.1Go for DMA...FRAMBO::BALZERWed May 03 1989 09:0015
    
    I'll be uploading the latest revision of my HD controller review on
    Friday, so just some short remarks.
    
    If you can afford it, get a DMA style controller like the A590 (which
    will also give you that RAM you want).
    The M.A.S.T interface strikes me as a bad (but probably cheap) design,
    since it won't DMA and you will have some problems printing AND
    accessing those disks. 
    And if (which I beg to doubt strongly) they can transfer 2.5 MB/s,
    your system will be doing nada, nichts, rien, nothing else.
    
    Later,

2525.2waiting for the A590ADODEM::MCGHIEThu May 04 1989 00:466
    I'm waiting for the A590 to be released here in Australia.
    
    It seems to me to be one the the better options for hard disk/memory
    expansion.

2525.3Really Soon Now... ;-)FRAMBO::BALZERFri May 05 1989 14:159
    
    The A590 should be out in the "nighted states" by now, and will
    be in civilized world RSN.
    Sorry for not uploading my review today, but I somehow munged that
    floppy, so it'll be monday.
    
    See ya,
