WDC contain plugin for possibility fast import(key "F") TRD images (640kB only) to ramdisc on Pentagon 1024kB = load TRD file as 16kB blocks to 1MB ram. On other clones with ramdisc can be used only classic and very slow "unTRD" command. Fast import = about 5 seconds.
I have rewrited source of TRDtoRAM plugin for other clones ZX PROFI 1024kB and ZS SCORPION 1024kB. Layout of ramdisc is same as on Pentagon 1024 then must be used TR-DOS 6.11Q with compatible ramdisc layout. I will soon release new versions of plugin (can be universal for all clones = with autodetection of memory paging ports)
