A proper HP16500C or better (series 17000) is way cheap nowadays. Myself
use a 16500C with lots of accessories (thank you, you know who you are!!!)
and a 16505A. Maybe it can help you. I don't know if there is an IDE
analyser for it (I have it for SCSI) but you can look for it. Or write a
module for it.

 is PIO 0-whatever only - no DMA involved....
 Damn this drives me nuts.... either I accept it, or I get a logic analyzer
 but the cost of such a thing..... :/
 
 There are some Chinese logic analyzers on eBay for well under $100. No
 idea how well they work.
