# A Question For Tim Stoddard

Can an external keyboard be wired up to a TS1500 in a similar manner as for a TS1000?

[Don Berry](http://localhost/indiv/don-berry/)  
Orlando, Florida

[Tim Stoddard](http://localhost/indiv/tim-stoddard/) replies: To compare keyboard connections, position both the TS1000 and the TS1500 with their non-component sides up and the expansion connector away from you. The larger connector is on the left on both of the computers and is wired the same except for reversing wires 5 & 6 (counting left to right) on the TS1500. The smaller connector is wired backwards in the 1500 compared to the TS1000. Following is a chart which compares the two computers. Hope this information helps.

```
large connector

TS1000     1 2 3 4 5 6 7 8
TS1500     1 2 3 4 6 5 7 8

small connector

TS1000     1 2 3 4 5
TS1500     5 4 3 2 1
```
