despite the ongoing work on #GlasgowInterfaceExplorer revD, we haven't forgotten our loyal revC users: I've just added a prototype for a RAM expansion board for revC that 1bitSquared has designed a few years ago it does pass the memory test, although the memory bandwidth is, at the moment, less than 2/3 of what's available with the faster revD FPGA https://github.com/GlasgowEmbedded/glasgow/pull/1268
