ah- that's 1 meg, not 1 gig! :-) this is a slightly confusing area because of the way the memory is divided in two & the way it is addressed. I don't know how much actual memory there is in either version in numbers of kB, but there were two sizes at the time my 2002 manual was written, "stock" & "expanded". [goes to reference library...] the 2002 manual says that the machines will contain 256 or 512 thousand 12-bit words in total. in real money, that's 384kB or 768kB of storage, which really isn't much, but is closer to matching the capacity of one or both sides of the old single density 3.5" discs we use. the book says that the stock machine used only one side of the floppy, which is probably where we get the idea that it's 1/2 a meg. the block count for an empty sample goes to 128, which probably means 128,000 12-bit words, & this is mirrored in the other half of the machine's memory to give a total of 256,000 12-bit words. I don't think there was an expansion beyond this, since it wouldn't have all fitted on one floppy; remember that the machines work with single-density discs only. duncan.
