#N:iuvax:5100001:000:410 iuvax!lwm Nov 29 02:15:00 1983 Does anyone out there have MODEM7 or equivalent already configured for a Morrow Micro Decision 2? I would like to get something on single- sided diskette all ready to go. Naturally I am willing to supply a diskette and sufficient money to cover postage and bother. I would be eternally (well, for a long time anyway) grateful. Larry Meehan pur-ee!iuvax!lwm (uucp) lwm@indiana (csnet)

I purchased a Morrow MD2 (used) last year for my father, and just now purchased a Kaypro II (used) for my wife. Thanks to MFDISK and UNIFORM I can exchange disks between the two. Given the limitations imposed by the Kaypro II drives (191K each) I'm planning to try the Micro-Cornucopia PRO-8 ROM with a pair of Mitsubishi disks (see article in M-C Dec. '85). Seems very straightforward. I'd like to do the same with the MD2; at least to get DSDD. That should just mean a new ROM if I stick to two drives; else some decoder logic changes. The M-C folks I talked to last week had never heard of such a thing. Of course the MD3 does just that. Question: Anyone done any sort of upgrade to a MD2? Anyone have a Schematic for the MD2? Anyone be willing to copy their MD3 ROM and determine any wiring diferences with the MD2 (i.e. have a MD3 schematic?)? Anyone have any help, at all, to offer? Pointers? Thank you. As I am just getting added to the mailing list, please direct any responses directly to me: BIRKEL@A.CS.CMU.EDU (or, old style, @CMU-CS-A)

The M-C folks I talked to last week had never heard of such a thing. Of course the MD3 does just that. Question: Anyone done any sort of upgrade to a MD2? We have not upgraded MD2s per se, but we have added additional drives to an MD3 to bring the configuration up to a total of four drives (2 DS, 2 SS). This required only that several locations in the BIOS be patched; it did not require a ROM change. Note, however, that the MD3 ROM has a DS personality which is designed to permit the reading/writing of SS diskettes in the DS drives. The process is "automatic"; i.e., the ROM responds to the presence of SS diskettes without user intervention. I do not know whether a ROM change would be required to implement what you desire, but I suspect not. Our MD3s are running BIOS 3.1; the MD2s 2.3. Anyone have a Schematic for the MD2? Anyone be willing to copy their MD3 ROM and determine any wiring diferences with the MD2 (i.e. have a MD3 schematic?)? I believe that the Morrow Owners Review (MOG) offers a technical information manual on the Morrow CP/M machines. MOG is at P O Box 5437, Berkeley CA, 94705. MOG publishes a user oriented magazine of the same name which is a good source of info about the Morrows.
