IWS Video adapter for the Sharp PC-1500 (Part 1)

Many of us have dreamed of this device!
But his selling price was 800DM did not make him accessible to all budgets.

It was designed by “Ingenieurbüro Walter Speidel” and sold a few hundred copies. To my knowledge the IWS is the only video interface for Sharp PC-1500.

So the mysterious listing we had:

IWS interface and PC-1500 connected to the TV IWS interface in it's original box

This peripheral offers the following features:
– Playback on TV with the resolution of 25×40 or 25×80 characters.
– Input / Output cassette
– Speaker Output

The save/load with the tape are faster than Sharp instructions.

It is accompanied by a user manual in A5 size.
All is correctly described, the new Basic instructions, the memory organization, except the schematics.

And there exist a 3 page correction to it :

It can connect directly to the PC-1500 but needs it’s only power adapter.

      Hi César,

      It’s like impossible to find one because only a few were produced. Maybe on eBay.de ?
      Good luck 😉
