Subject: Re: S-100 disk system upgrades - info request

 I have a tarbell dd disk controller which ran
 flawlessly for a year (I switched to a different
 controller for reasons havinf nothing to do with
 the tarbell board) and never had a single problem.
 This was in conjunction with an 8mhz 8086 in both
 a terminated and unterminated busses at various
 times).
 
 The board handles any combination of single/double
 density and single/double sided drives. One nice
 feature is that data transfer can be either by dma
 or by pio (so it will work in systems with dynamic
 memory or other dma constraints).  Physically the
 board is of high quality and the documentation is
 both extensive and clear.  I once had the tarbell
 single density controller and when I had a problem
 with it the tarbell people were quite helpful (in
 fact they used to offer a deal whereby if you bought
 a kit rather than a&t and couldn't get it to work
 after assembly they would fix it free of charge).
 
 It can be found (check byte) for $419 from various
 mail order houses.
