H89 disk imaging

Hi Dan Unless you know something I don't about disk formats, you can not read double single density format with a double density controller. It isn't that you'll just get 16 bits instead of 8 bits, things like sync makers will not work. In any case, I currently have a method of transferring hard sectored 40 track disk images to and from the following platforms to a PC running DOS: Z/H90 w/ serial card H89 w/ serial card H8 w/ H8-5 serial/cassette card H8 w/ H8-4 serial card ( Note: The H8's may be either an 8080 w/ PAM8 or a Z80 w/ XCON8 ). The DOS machine needs a serial port. My setup can also be used to bootstrap a machine that one has no access to disk with code on them. You only need the blank disks to copy the images to to bring up a system. Dwight ps I hope Dan is on our mail list because I no longer email directly to queries from off list. See my previous post.
