@ those who have an 8088 card,

I have started checking the re-engineered schematic against a PDF I 
found or was given lately. This PDF shows the 2nd part of U29, 
74LS74, as being a spare. In my SCH it has been used to generate 
BUSY2 at pin 36 of connector JP2. Things can be checked by testing 
if pin 11 has been connected with pin 3 and 13 with 10 of U22, 
another 74LS74.

I hope some of you can check this out, please. Two questions that 
comes to my mind is:
- is there more than one version?
- or is the PDF a pre-production version?

TIA!
