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.

3.1.3Jumper 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.

3.1.4Jumper 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.
