CCTech folk, I have available, for the cost of postage, a pair of DEC boot ROMs used with the M9312. They are the 23-755A9 and 758A9 devices. Additional notations I got with them indicate that they were used with Spectra Logic controllers. The 755 is, apparently, for booting DPn or DBn disks, while the 758 is for booting MTn devices. First respondent gets 'em. Thanks much. -=-=-=-=-=-=-=-=-=-=-=- Bruce Lane, Owner & Head Hardware Heavy, Blue Feather Technologies -- http://www.bluefeathertech.com kyrrin (at) bluefeathertech do/t c=o=m "If Salvador Dali had owned a computer, would it have been equipped with surreal ports?"
