A #1571, device #10, is dedicated to holding one of the copy-protected Pocket2 
programs, so that I can have quick access to it.  

I  am  using  the  128 version of the program, so the second side of the disk, 
when  flipped over, which has the 64 version went unused.  To make this second 
side  of  the  disk,  with  its 160k of space available for additional program 
material,  (and with a lot of help), and using U0>M0, and U0>H1, and HEADER, I 
got  a  successful format of the top side, and a directory showing 160k of new 
found space.  

Several  programs  were then saved to side H1, quite easilly.  The prob I have 
run  into, however, is that of loading these programs from side H1.  A program 
that  loads in 4 seconds from a #1581, or a double-sided formatted #1571 disk, 
now takes over 32 seconds to load, from side H1, of this two-sided disk.  [The 
Pocket2  program,  which  is  on side H0 of the same disk loads and runs in 31 
seconds, but the Pocket2 program is longer, by a factor of 6, than is the side 
H1 program being tested.]

This #1571 has one of the first available upgrade replacement ROM's, which was 
supposed  to  correct  the  slow  write/read  prob with the second side of the 
drive.  I  know  the ROM corrected the prob with double-sided formatted disks, 
but  wasn't  it  also  supposed to correct the prob with a two-sided formatted 
disk?  Any  suggestions  for  getting side H1 to load as fast as side H0 would 
really be welcome.
