April 6, 2014 – FreHD for Diskless System Now Available



Ian Mavric has completed testing and is now making a version of the FreHD kit with all the parts needed to make it work on a diskless (cassette based) Model III or 4 with no disk drives. People with cassette-based machines can now do something useful with them.

More information can be found at Ian’s web site

March 22, 2014 – Catweasel Software Mods Progressing

March 22, 2014 – Catweasel Software Mods Progressing


Despite not even having a Catweasel card, George Phillips has made amazing strides with modifying Tim Mann’s Catweasel software to output the BEST track read instead of the LAST track read. He is toying with the idea of actually repairing bad sectors based on bytes which are read differently, bringing a far higher level of granularity than I would have hoped. Stay tuned, and thanks George!

March 17, 2014 – New DMK Utility and Raspberry Pi Virtual Floppy Drive


Alan Page has created a utility which will view and edit DMK images as well as allow for side-by-side sector and track comparison of two DMK’s. It works on single, double, and mixed density DMK’s. CRC’s are updated with changes. Downloads can be had at Alan’s Blog Page

Alan is also developing a virtual floppy drive based on the Raspberry Pi which can, among other things, use a raspeberry pi and his add-on board to read real TRS-80 disks into DMK images. Alan’s trials, tribulations, and explanations can be found on his Raspberry Pi Virtual Floppy Drive pages.

March 4, 2014 – Converting Disks


With George Phillips having prepared a beta of a cached-best-track modification to CW2DMK, I find myself in need of test disks. For those visitors out there who have not yet sent in their disks for converting, now would be a great time :) Please remember that the data on these disks isn’t getting any fresher!

February 21, 2014 – Any C Programmers Out There?

February 21, 2014 – Any C Programmers Out There?


Update: George Phillips, author of the Model I/III/4 emulator TRS80GP has graciously offered to do the feature implementation. Thank you George!

If anyone out there is fairly proficient in old timey C, has some time on their hands, and thinks they can handle this project, please let me know. As many of you may know, Tim Mann has developed amazing software to use a Catweasel to read and write TRS-80 disks. As I have learned from reading tens of thousands of disks, not every disk has fared so well over the past 35 years, and it is quite disheartening to see the program undergo numerous retries of varying success on a given track, to wind up giving fewer good sectors than it had read on a previous retry, simply because the retry counter expired and THAT read wasn’t as good.

To this end, if anyone out there can assist in tweaking the existing CW2DMK code which Tim Mann has prepared so that each time a track is read, the good sectors are put into an array, and when the read is done, the track is written out from that array; ensuring that if a sector was read good even once, it will be there for the output, instead of being discarded by each successive track retry. It would be best to set this up as enabled by a command line trigger, so those who wish to read without the cache can do so.

Any volunteers?
