the number of address setting options decrease to just eight. See section 3.1.6 for the
description of jumper B16s function and the entire "address setting options" table.
A jumper set results in the related address line being assigned a logical low (0) function.
Remember!
When replacing an existing "Original-VMOD" only eight addresses were
available $FE0400 (as per default above), and addresses equal to AB#05,
AB#09, AB#13, AB#17, AB#21, AB#25 and AB#29 as shown in table 3-6.
3.1.3 Jumper B3 Address Modifiers
Jumper B3 provides the VMOD-2 user with two different address modifier options. The user
can have Short Access, 29/2D, or Standard Access, 39/3D/00.
3.1.4 Jumper B4...B11 Interrupt Vector
Jumpers B4... B11 provide a binary coded interrupt vector, B4 = MSB, which subject to the
setting of jumper B01, may be used to give an interrupt vector for either or both piggybacks.
The user can have these settings ignored when using two "intelligent" piggybacks (i.e. capa-
ble of generating on-board interrupt vectors), by setting jumper B01 to fully open.
The jumper B11 is a three-pin type and can be used to differentiate when the user wants the
piggybacks to have identical or different Interrupt Vector Addresses.
