Yes, I know that.

Ah, I didn't know that :-)
In fact, on the schematic reported on a manual I have got (VIR REVEALED
by Nick Hampshire) the RAM is reported to be composed by 2114s only. My
VIC 20 CR has got three 2114s and a couple of 6116 (or equivalent, I
don't remember the exact code) instead.

If you can, it will be fine. Thank you, again!
