   Hi all,   
      
     Just acquired a Model III and DD 1 is giving me some problems.   
   I do a little bit of electronics work, so thought I'd give it a   
   shot. Touched up the cold solder on the power connector and she   
   sprang to life. Well, sort of. The drive gave me all sorts of   
   trouble reading disks until I played around with the tiny blue   
   pot that sounds as if it controls the speed. Having gotten the   
   drive into the closest spec I could (it read the directory and   
   booted MOST programs off the disk), the frickin' motor died on me!   
   Or... the TIP 110 transistor went. I desoldered her and took some   
   readings off my DMM. It does indeed appear fried. Off to RatShack,   
   only to find that's probably something else they no longer carry. lol   
   Having said that, I just looked and an NPN TIP 120 looks like she'll   
   do the trick.   
      
   Still... got me to wondering: can you set up a RAM disk of sorts   
   on the TRS-80's? One could get away with 1 drive if you threw the   
   contents of LDOS into RAM, wrote an assignable and then stuck in   
   your program disk. Not every single Model III had 2 drives, did they?   
   There's got to be a work-a-round if I can't get this poor thing to   
   work...   
      
   TIA for any help or pointers here.
