have you read the manual on the B32 with wordwise ? last few pages on the manual ?



Computer Concepts ROMs
Most of the current Computer Concepts ROMs are capable of working with
shadow RAM systems. If you find that you have a version of a Computer
Concepts ROM which does not appear to function correctly with shadow
RAM, you should contact Computer Concepts for an upgrade to the latest
version.
Wordwise-Plus
Note that you will need Wordwise-Plus version 1.4D or later for the
technique described here to work.
Because it was written before shadow RAM systems were developed,
Wordwise-Plus is a special case. There is no way of using shadow RAM
to allow you to edit text in an 80-column screen mode (you will need
INTER-WORD for that!). However, it is possible to use ARIES-B32 shadow
RAM to preview long documents in 80-column format.
You will need to program two function keys as follows:
*KEY 0 *XOFF 2|M|M|[{RETURN}
*KEY 7 *XON|M|M7 {RETURN}
To go from the main menu to editing your document, press {f0} (
function key 0). To return to the menu after editing your document,
press {ESCAPE} in the normal way. To preview your document in 80-
column format, press {f7}.
ROMs Written Specifically for ARIES—B20
Very much against our advice, some ROMs have been written which rely on
the shadow RAM hardware being identical to ARIES-B20. These ROMs will
not work with ARIES-B32 without modification.
- 50 -ARIES-B32 provides a special command which copies a ROM image into
sideways RAM and alters any parts of the software which explicitly
refer to ARIES-B20 hardware to work correctly with ARIES-B32 hardware.
Depending on the size of the ROM you wish to patch, you will need to
have a bank of either 8K or 16K of sideways RAM available. If
necessary, you can use *XON 16 to split ARIES-B32's RAM into 16K shadow
RAM and 16K sideways RAM in bank 14.
The command '*XKLUDGE' finds the ROM whose name you specify (in the
same way as in *RKILL), regardless of which sideways socket it is
fitted into, and places the patched version into the sideways RAM bank
you specify.
A complete sequence of commands to place a patched copy of Wordwise 1.
20 in sideways RAM bank 14 is:
*XKLUDGE WORDWISE 14{RETURN}
{BREAK}
If you are using a bank of sideways RAM whose number is higher than
that of the original ROM, then you can enter the modified copy of the
software directly, in the normal way. If, however, you are using
sideways RAM in bank 0 for the patched copy, you should first use
*RKILL to disable the original ROM, as otherwise the operating system
will take the higher-numbered socket, containing the original,
incorrect version.
