I pulled out of storage some Atari data disks formatted with DOS 2.5. The first few times I accessed the disks on my 800XL/1050 combo I was able to perform a directory listing and open any data files (print to screen). For some reason I now cannot access anything on these disks. No file list, nothing. I sometimes get an Error 138 when trying to read the directory on one of these disks with MyDos. I can access many other disks with no problem. I tried using Copymate to preform a sector copy, but it found no data. Any ideas what's going on here or what else I can try?
This is a neat device that emulates 1-2 ST506/ST412 or other MFM hard disks for reading and or writing. Can be used to pull data off disks or to emulate disks for that old computer you don't have drives for. I think I read somewhere it can be passed thru to a VM. Possibly this could work for MAME/MESS emulated systems? TI-99 has been tested with the system and works for reading WDS-100 disks. Emulation works for reading, but writing fails this point. Probably have to be patched for the TI/Myarc sector layouts, directory structure, bitmaps, etc. (not enough info yet to correct, it says), but the actual writing appears to work. Works with a wide variety of other systems. List here: http://www.pdp8online.com/mfm/status.shtml There is a group buy under way right now if you want to check it out. Pricing seems reasonable. http://www.pdp8online.com/mfm/ Emulator uses a BeagleBone Black/BeagleBone Green Wireless for the actual processing. Interesting. Go team, TI! 🙂
