Thank you very much for the kind words. Congratulations on your interest in hands-on computer design. I too have worked on an 1130, but it doesn't have the same sentimental attachment, understandable, really. For the youngsters on the list, here's a bit of my personal computin

I am looking into the design of a processor to implement P4 Pascal. Since I plan to use the Spartan 3 Starter Board it appears I should probably design around the 32 bit memory system and that is more than adequate for the stack machine and integer arithmetic. Strings and set

Does anyone have information on where I might get a free (or very low cost) CRT core? I am looking for text only, 25 lines of 80 chars. On the surface the design seems simple enough but if it has already been done there is not much point in doing it again. I have some space

Hi all, I am trying to interface a ps2 keyboard to the Xilinx Spartan2 FPGA I have. I have connected the keyboard to the Digilab DIO1 board and see no activity on the PS2D and PS2C pins when I use a logic analyser, and even when I pick inputs from the relevent FPGA pins and try

In Altera development kits ,I can't find the description about it. The Nios(tm) CPU soft core is a 16/32-bit RISC CPU core,specially, it has the sliding register file windows technology. So I think it maybe support hardware multi-thread technology,but I can't find the relatial ma
