My senior year of college, someone gave me an 11; sadly, it didn't fit into the back of the (then new) '86 CRX when packing everything up for the trip home. My memory is a bit hazy, but it was one of the small Unibus boxes, with a discrete TTL cpu; perhaps an /04 or /05. At a recent hamswap, someone was giving away a DECwriter, but I resisted the temptation ( and it wouldn't fit in the trunk anyway. ) My personal DEC favorites are the 8/E and 12, the machines I used in high school. The local surplus store had a moving sale a while back, at which I picked up 14, 1K x 4, 10 ns ECL SRAMS, which would make a nice fast 4k x 12 memory ( plus a couple spares ). Now I just need to find some surplus 10181 ALU's and start designing a hypothetical early 80's vintage ECL PDP-8 :) To (almost) veer back on topic, the Dynachip (RIP) DL50xx FPGAs with ECL I/O would work nicely for that application, but I haven't come across any yet. Speaking of FPGA CPU's, I hope to have an update to the YARD-1 posted soon, but I first need to update my PC from Win-98 to XP so I can use the latest 5.x Xilinx S/W. Anyone gone through that experience yet? Re. running the Xilinx S/W on a non-networked single processor box, does the 'home' version of XP have any major restrictions ( max memory, etc.) vs. the 'professional' version of XP? Brian |

Slashdot brought up my old friend Forth today http://books.slashdot.org/books/02/10/27/211220.shtml?tid6 Do you know it? Nothing better for small, fast, elegant computing. You jump table guys would love this. A Forth processor is easy and elegant too. How small can you make one? Can an entire Forth system fit into a single Virtex-II blockRAM? Dualported, one BRAM can serve two processors. They could share another BRAM for data and stack. One processor per BRAM? Can you make the processor small enough to match, so for example your XC2V40 has four processors? (XC2V40 is $32 in singles and WebPACK supports it.) Or Spartan-II just as well. --Mike |
