OMG you guys and gals, how amazed am I to find this site!
OK so SAM came down this morning. SCART lead into a TV, expecting a big bang and magic smoke when SAMs PSU is plugged in (nope) - but the old chap only went and fired up first time. He lives with all 512K of RAM! OK so the two (Citizen) drives are not playing yet, but I've two new belts on order, so lets see. Tried to read my MasterDOS and MasterBASIC floppy's in the PC and they don't read - so really glad to see not only the disk images but also the manuals here - how fantastic! Also great to see SC_Assembler here, so I'll be downloading that... 29 years ago SAM, SC and some homebrew hardware was responsible for helping me get my Elec Eng degree through both allowing me to write the assembler for my final year project, but also, using PCGs "The DTP Pack" which they ported to SAM, for letting me write my final year project dissertation in the comfort of my halls of residence room, rather than having to traipse down to the University Computer Centre every freezing cold northern-UK morning to write the thing.
Let's see how SAM goes in the coming days and if I can breathe any life into the floppy drives!
