The A1000Jr variants

A1000Jr Variations
Developer: Commodore International
Year of development: 1989-1991

A few months after the cancellation of the A1000+ and A3000+ it was decided the company should attempt to salvage the A1000+ technology and build a lower spec ECS-based machine. The project was developed under the codename 'A1000jr', an unofficial title intended to annoy Bill Sydnes.
In an e-mail exchange, Dave Haynie commented on one of the changes made to the A1000jr design:

"They did the backplanes 2-layer, and when I pointed out that Zorro III didn't run on a 2-layer backplane, they disabled Zorro III mode, so these were Zorro-II only."
After months of development four configurations were produced for the mid-range market. These would fit between the A500 and A3000 in the Commodore product line.
 
Model CPU Number of Zorro II slots
A2200 68020 2
A2400 4
A3200 68030 2
A3400 4

The finished products were production-worthy, but were never ordered by a sales company within Commodore. In an attempt to recoup the cost of development, Commodore reused the case design for the A4000 a year later, and upgraded the A1000Jr configuration into the A3200.
