I am happy to inform you that the improvements I have made to the already obsolete Sord emulator have been added to the official MAME distribution, specifically to version 0.171. Compared to the current
version it can now emulate EM-5 32kB, 64kBi, 64kBF and 64kRX memory modules. This allows you run programs that was not working due to lack of RAM. For this reason, another slot for cartridges was added
so that the memory can be "inserted" together with one of the Basics. Then there was added a modification called Brno according to the place of origin, which contains a CP-M with a 1MB RAM ramdisk. I intend to constantly improve this driver, if time allows. Unfortunately, after the official version was released I realized that I forget to add support for uploading LST files. If you need this function, download my version, which already contains this feature.
