I while back someone was asking about the schematic I had posted outlining
how to construct a 5.25" drive for the amiga. The question was:
in the following:
+++++++++++++++++++++++++ (A)
+ |
Symbols: + | 4
------- resistor: + o---|\ 6
______ + | | |O------
! ! | + o---|/
! chip ! \ + 5
!______! / +
\ + (A)
NAND gate: | + |
+ |
-----|\ + o-----o-----o-----o
| |O---- + | | | |
-----|/ + ____|_____|_____|_____|______
+ ! !
junction no-junction + ! 10 11 12 13 ! 8
+ ! Q !-----
| | + ! !
--o-- --|-- + ! 1/2 7474 _ !
| | + ! Q !-----
+ ! ! 9
+++++++++++++++++++++++++ !_____________________________!
...what does (A) connect to.
I have not built the drive, but I did the translation of the schematic to
computer readable form and what was ment there (I figure) was for all points
labelled (A) to be connected to each other.
I hope that this answers your questions.

I sure do appreciate this service, I have used it many a time, like when
we didn't get hack.12 and hack.13.
