Lines: 21 Summary: Ramdisk Prototype The prototype kit will be a chip that talks directly to the hard disk port and controls either 256k or 1MEG chips. Also there will be a pcb that sits 256k chips of 1/4 meg increments upto 2 MEG. Basically you add rams, power supply and a case. It was decided to make the pcb for 256K chips because of availability. I get ten chips back for the first fab. The design is in progress. The company doing the fab, Alberta Microelectronics Center has a bunch of rules that have to be followed before actual fab takes place, i.e. a dicrete prototype, chip simulation, blah. One the most costly things of this kit will be a power supply. Seems one of the best things to do is by an Atari power supply. There pretty cheap. Soon, I will post a spec on the chip. I listened to all who sent mail, thus, I think I'm doing this right. The chip can handle lots of memory, you can still hook up your hard disks, the pcb has hooks for battery backup, and whatever. Glen
