No, it won't fit on an isp1048 PLD, but then the MinForth didn't either. It used external memory, no? The B16 and my designs will run entirely on an FPGA without external memory. If the 1048 in isp1048 indicates the number of LUTs or macrocells, then my design would fit the isp1048 other than the memory used. In fact, it only uses 600 LUTs the last time I built it. I didn't try to make my CPU design fit an isp1048 because I have no reason to use obsolete technology. When I can get a 1280 LUT FPGA with 8 kB of RAM for under $4 that draws microAmps of current, why would I use something like an isp1048? That goes for MCU chips too. There is no need for a MinForth device the way it was built. It would be much more expensive than a basic ARM running off internal memory with much higher processing speeds available than the MinForth. -- Rick
