Hi, I've seen this board mentioned in a number of post, but in sort of an off handed manner. https://webstore.kryoflux.com/catalog/product_info.php?products_id=30&osCsid=a6388d9b56b704f3508ee011d400fa76 I was wondering how people use it for transferring TI files, and how successful they have been. Ideally, I could hook this up with a 5.25" drive to my PC, and dump files and use them with Classic99/PC99/MAME ? Thanks
I came by this accidentally while scanning some old newsletters. I could find little reference to the company named except: Asgard News Does anyone know if it was actually manufactured, if so, did it live up to its claims? Thanks
Just completed my 80-track Mod. Will thoroughly check all solder points before plugging in. Which I can't do until the weekend. Hope I done good. I took lots of photos, some might make good prints for wall art. https://www.facebook.com/photo.php?fbid=10206865163899614&set=a.2902404651182.2113402.1592441926&type=3
Is there a disassembly available of the standard TI-Disk Controller DSR ? Reason I'm asking is that I have some File reading stuff in assembly that works fine in JS99er and classic99 but which locks up on the TI-99/4a with PEB and standard TI-Disk Controller. I'm currently using a modified version of Paolo Bagnaresi DSRLNK code. What I'm trying to come up with, is a scratchpad memory map of the minimal requirements for doing file I/O (I'll post the memory map at a later time) For that I collected information from the documents posted in the Development Resources Thread, classic99 source code (mainly disk.cpp and ScratchPadCorruptList), Thierry's site, jedimat's TIPI source code, etc. Even though there are many documents describing File I/O and DSR's floating around, there seems to be still quite some confusion as far as the exact used memory location are concerned. The standard for me would be the TI-99/4A Disk Controller and go from there. ... and while we're at it. Is there a disassembly of the Editor/Assembler DSRLNK available somewhere?
