Message-ID: <3160@soma.bcm.tmc.edu> Date: Tue, 21-Jul-87 14:02:21 EDT Article-I.D.: soma.3160 Posted: Tue Jul 21 14:02:21 1987 Date-Received: Sun, 26-Jul-87 21:08:45 EDT Sender: masscomp@soma.bcm.tmc.edu Reply-To: trejo@nprdc.arpa Lines: 14 Approved: masscomp@soma.bcm.tmc.edu I'm 87.5 percent sure that the custom products engineering group at Masscomp has already written an Ikon DR11W-emulator driver, which has been used, I hear, to control special purpose graphics processors, such as a Lexidata Lex-90. Mitch Kuninsky there might be able to help you; Brian Rich also. You can reach them at (800) 992-5000. If the driver has already been written, the price shouldn't be too exorbitant. I'd like to know if you do get your driver running. I'd be particularly interested to know if you can support burst DMA mode (no bus arbitration between each DMA word transfer) and what DMA transfer rates you can attain. Len Trejo
