Hi I wonder why Commodore bothered to release,what I suppose must have been a really low spec machine compared to what else there was to choose from. very best wishes Brian.
The A600 marked the move to surface mount technology which improved reliability and lowered production costs. Due to it's smaller footprint, there would also have been savings on raw materials, storage and shipping.
Limited expansion capability would more likely mean a customer would buy more powerful machine in the future when it became too limited for them.
