I'll have to think about it, it's too big to live on a breadboard.<br />Thanks,<br />JSilvaAnonymoushttps://www.blogger.com/profile/14558830794909772691noreply@blogger.comtag:blogger.com,1999:blog-1311381797415896809.post-77730771518842363432011-03-27T05:29:03.864+02:002011-03-27T05:29:03.864+02:00I was recently updating my simplified FAT code to ...I was recently updating my simplified FAT code to add support for FAT32 and while I was at it I decided to update my SD code to handle SDHC. You can see the earlier version in the page I cobbled up for the SparkFun Logomatic.<br /><br />http://home.earthlink.net/~schultdw/logOmatic/<br /><br />I think that the code you are using is the same as used in the V2 Logomatic and I wasn't impressed with it. It uses a long out of date initialization method and the attempt at buffering doesn't work very well and shouldn't be in this code to begin with.<br /><br />I dug out my CP/M-68K disks and after some effort I was able to get cmptools to read them. It has been 20 years since I last looked at them so they didn't do too bad.Unknownhttps://www.blogger.com/profile/04612050618735435202noreply@blogger.comtag:blogger.com,1999:blog-1311381797415896809.post-80667768233048305552011-03-21T21:07:24.083+01:002011-03-21T21:07:24.083+01:00I David!

Thanks for stopping by!<br />No, your not too late, although I've selected the SDCARD instead of the floppy (breadboard space more than technical).<br />I have stumbled upon a "mental block" and a new installation of linux... but I'll get back to it once I finish a few other (more simple) projects.<br />Thanks for the note!<br />JSilvaAnonymoushttps://www.blogger.com/profile/14558830794909772691noreply@blogger.comtag:blogger.com,1999:blog-1311381797415896809.post-58839257996638336172011-03-15T01:17:13.957+01:002011-03-15T01:17:13.957+01:00Just stumbled on this blog so I hope this isn'...Just stumbled on this blog so I hope this isn't too late...<br /><br />The 4MHZ 68008 is more than fast enough to drive a floppy disk controller. I installed CP/M-68K onto a MEX68KECB many years ago and it used a 4MHz 68000. (At least it did till I doubled the clock speed.) <br /><br />Getting CP/M-68K running isn't too hard and can be done with minimal tools. The trick is that there is a bare version of the BDOS on disk and all you have to do is patch a couple of addresses into it for your BIOS. Your BIOS can be dead simple. Once it is running you can then use the C compiler to build a better one.Unknownhttps://www.blogger.com/profile/04612050618735435202noreply@blogger.com
