Hi,
I was tipped off to your group by a fellow computer hobbyist.

Question -  Is there anyone in the Philadelphia area (within 200 miles) 
that fixes teletypes?  My ASR 33 is close to working but it needs some 
TLC after being knocked over.  Some of the keys are bent, perhaps a cam 
or two. Considering how destroyed it was before I stared putting it back 
together I am impressed how well these things can be fixed, but I may 
need help with the last mile on this project.  The 33 does send and 
receive commands to my SWTPC 6800 computer, but when the carriage 
returns it's slow to get into the start position, and does not complete 
the trip until after the first character is printed.  Because the 
carriage is still sliding back to the left, the 2nd character is printed 
where the 1st should be, and the 3rd is typed over the 1st as the 
carriage moves right horizontally typing the line on the page.

Let's say that the line to be printed is S1000000000

What happens is:
*_S* (the _ represents the space remaining for the carriage to finish 
returning to the rest position, the first character prints approx. where 
the 2nd character should)

*1S*  (now that the carriage has finished returning, the 2nd character 
prints in what should be the 1st character's spot)

*1S000000000* (where S = the 3rd character of the line is typed over the 
1st character of the line)


Thanks in advance.
