Some Apple IIc -=love=- from UltimateMicro’s Facebook page:
Speaking of the IDEA2c Drive (from the last post)- A proto is now assembled and being tested. We will be moving from standard chips to custom logic (CPLD). This board however is a hybrid of both designs, and will allow us to move one IC at a time in to the CPLD and continue testing to ensure we have correctly emulated the standard logic. As chips are integrated we then cut the traces on the PCB, or just remove the IC from its socket.
As you may have noticed, we have ordered this proto with a few examples of the new logo printed on it, and also the move to Altera MAX7000S CPLDs. Both items will be standard on all future projects.
The next version of this board should include a Clock and Aux RAM, however we may even see a decrease in total physical size of the board. Even the current PCB didn’t need to be as large as it is. We mainly wanted to document what the physical size limits were in case we need more room in the future.
The board will connect using the CPU and MMU sockets on the IIc or IIc+ motherboard. We did find some IIc units that had the MMU soldered to the motherboard. In this case we will offer a service to remove the MMU and add a socket.
Work continues in the ReActiveMicro, and more updates to come!
