Description
Congratulations on your purchase of the new 838-IO Plus peripheral expansion card.
This card is a direct replacement for the Flex Cable Interface for the TI-99/4 and TI-99/4A
home computers.
The card removes the large firehose cable and elephant foot interface card from the side of
the TI-99/4 and TI-99/4A computers. It is replaced with a vertical standing card and a new
DB37 double shielded twisted paired cable that is now connected from the back of the unit.
This will free up desk space for your TI computer!
There is also an optional 32k module that mounts on the actual 838-IOP card that plugs into
the side port TI bus, which frees up an PEB slot!
More expansion cards are planned in the near future.
