IRIS 4D/20 memory upgrade

[James Helman]

I prefer to buy memory that the third-party manufacturer claims works
on a machine, rather than taking chances with stuff off the shelf at
the local electronics shop.  That way you can always send it back if
it doesn't work as promised.  Also, lifetime warranties are valuable,
especially on board level products.

Clearpoint sells memory for the 4D/20 through 4D/80.  Helios sells
memory for the 4D/2x0 series.  Clearpoint's number is 1-800-CLEARPT.
I don't have Helios' number.  Or contact any reasonable size memory/
peripheral distributor.  Among the ones in Northern California, we've
found CITA in Sacremento (916) 344-5558 to have good prices and
service.
