010 Adapters
Upgrades are available to convert the larger system board slots to srnaller DIO card slots in the
computer or the HP 98570A expander. Only one upgrade may be located in the computer.
HP 98242A 4-510t 010 Adapter
This adapter converts two system slots to four DIO slots. The HP 98242A is standard in the
HP 98570A Expander, but may be deleted using Option 004. For customers who delete it when
they purchase the expander, but later wish to add it, the adapter is also available separately.

The second adapter converts one system slot to two DIO slots. Use it with Model 350 when
no bit-mapped video board is used, such as terminal-based multi-user systems. Some bundled
systems will have it installed to accomodate the HP 98700A's DIO interface card.
DIO interface cards may only be located in every other slot. HP 98256/7 RAM cards are not
supported. Thus, the 4-slot DIO upgrade is essentially a 2-slot upgrade, and the 2-slot upgrade
is essentially a single slot upgrade.
