The difference in availability is of no importance, because if you cannot get
any of the connectors suggested (tulip, jack, DIN8 or DIN5) you can neither
get a DB9! But any self respecting hardware store has all of these in stock.
About using a DIN5, this is also very much possible. In which case I suggest
to use pin 5 as GND and leave the rest as it was with DIN8.
So:
SEND (DIN5 male) RECV (DIN5 female)
D0 1 ---------------+ +-------------- 1 D0
D1 2 -------------+ | | +------------ 2 D1
ACK 3 -----------+ | | | | +---------- 3 ACK
GND 5 -----------|-|-|--|-|-|--+------- 5 GND
| | | | | | |
| | | | | | |
3 7 6 1 2 8 9
MSX (DB9 female)
female male
3 1 1 3
5 4 4 5
2 2

Do you think you can do this? Can you elaborate a bit more on the
method you are thinking of using?

Yes it is. Since a shielded cable is less sensitive to electro magnetic
interference, I suggest using a shielded cable. Just connect all GND's to
this 'shield'
But we aren't using that long a cable, so it wouldn't hurt if you used
non-shielded cable, in which case you connect your GND's to one of the
normal lines. -JUST USE THAT GROUND- ;-)
