Not used this turbo 2000 thing (but i think it's a similar concept to rambit, a UK turbo upgrade for 1010's, and possibly the xc series)

 

I think the 'start' thing, is somewhat likened to casini/dosini and dosvec i.e it's asking for a run/init address (so i guess it can run/execute your program)

 

And 'from' might be something to to with the start location of the program

 

or it could be the other way around, from could be the run/init address and start could be the start ram location of your cassette program

 

Bytes, i think that refers to the total lenght of the program data (dunno if that includes any loader(in bytes)

 

If you look at a cassette loader in something like omnimon/qmeg etc look for any referrences to 'iocb' locations (since very few programs on cassette used 'dcb' locations) the first set of iocb commands usually tells the computer to open the cassete, the next set of iocb commands tells the cassette to load the next block of data (after the loader) at xxxxh address (that is the address you are interested in (since that is where your cassette program starts to load from in ram)

 

Sorry, i forgot what the locations for iocb are (i think they start at $34x and extend to $3bx) but the dcb locations are 0300h to 030bh (there is one ataricassette program, atlantis's 'gunfighter' that uses the disk buffer location (0240/0241h) for it's cassette load routine)

 

If you use ebay, try looking for rambit's turbo tape upgrade (i think it used to be sold by derek fern/micro discount), I have'nt used that one but it had a automated conversion program that from i understand required little user input (apart from swapping the tapes over) and a few other things

 

I dunno how simple/easy the rambit turbo tape upgrade was to install/fit in a 1010 or xc series
