ram disk in typdos

Looking at the tyrdos flying in ZX.SPECTRUM, I decided
to try to insert a RAM disk into my tyrdos, presumably
will use all the additional memory on the stumps, work
with all 128 programs using the DOS address
#3d13 to call. If you convince me that this is necessary, then I may
do it, but I don’t promise anything.
By the way, I advise that typdos that flew into ZX.SPECTRUM
not to sew itself up, because that RAM disk that was made there is a big
perversion and will not work with most software.

Sincerely, Andrey.
