An FPGA-based LGP-30 Replica
- ozymandiax 2y agoMy favourite computer... timing instruction placement on the drum. Juergen is actually planning to make a batch of kits later this year!
- bewo001 2y agoMy late father was a maintenance technician for those things. He hated it when programmers did smart instruction placement to optimize drum timing. When the drum speed was a little off, they called him to calibrate it so their programs would run fast again.

- dailykoder 2y agoCute project! > Xilinx tech support page and a forum post explaining how to get the Xilinx ISE to run under Windows 8 or Windows 10. Unfortunately Xilinx no longer maintains this development suite, but has also considered it unnecessary to support their Spartan 6 platform in the successor software suite, Vivado… Wasn't the Spartan 6 also supported by the open source toolchains? I just did a couple seconds of search and I could only find the yosys support, but no nextpnr. Sad. Xilinx/AMD should open that up
- fer 2y agoI haven't done it, but 7-series is theoretically supported by SymbiFlow tools[0], even though the bitstream generation still requires Xilinx's bitgen. [0]https://github.com/symbiflow https://github.com/symbiflow
- zombot 2y agoThat's impressive. It looks like the original LGP-30 computer should have made IBM jealous. > Oscilloscope monitors internal activity. Now that is downright romantic. What other computer offers entertainment like this?
- jecel 2y agoFor a serial computer, an oscilloscope will easily do what a set of blinking lights will do for a parallel computer. By trading time for space it gives you a free serial to parallel conversion.
