  Want me to tell you about blocker
Port # 1FFD to Scorpio, who invented
Nemo for KAY-1024 (however, nothing in the docks of it has 
not)? No ... And I still well tell you, because like other

themes do not have (you did not ask and do not
come up with, here I write just nonsense).

  In general, it is necessary overlogging only two roads, and 
add three Circuits, and tumbler. 


  It goes without saying, they should use as described in the 
ZF # 1. Ie mostly Menu BASIC-128 and its shadow businesses 
klatsat not recommended. I mean, to cut down port

can be a TR-DOS'e or boot'e.

  Something a little section is obtained. Do you know how there 
memory doubling possible? Um, but why are you extra bit of 
hitch are you? Bend a stupid. Do not know how our coders memory

identify. They only recognize the components:
flipped bit, and all believe that the Pentagon-512, cracked-ROM 
means Profi ... And, in short, think of yourself. You can, for 
example, put a toggle type pent512 - scorp256. And you can even 
kill a shadow businesses and remake a pent512 ...

  Naturally, we must still soldered on top
RU7 line (41,256, etc), do not forget to bend your legs 15'ye 
it will CAS1 /. Old CAS / must be cut off from the foot of the 
15'h RU'shek that the board and apply for the scheme.

And these RU'shki return CAS0 /.

  If a little more, then a14a15-select signal box # c000 (a14 
and a15, filed on LA3); H1M-means an appeal to RAM per cent, 
instead of / controller. The rest seem to be clear. 

  By the way, signs are given under the "green card (because 
the other schemes I and no)




  p.s. I deliberately did not lead pinout
m / s and a specific bit of memory expansion.
Because the kettle is better with a soldering iron in
PC does not climb, it will be worse. And if you already
have some experience, then get the desired
Old is not difficult.
