Ah, yes. That's what I mean.
meaning to ask if anyone has fully stuffed a
512KB MSV11-PK and turned
it into a 1MB MSV11-PL?
Do you mean turn a 256KB MSV11-PK into a 512KB MSV11-PL? I have an M8067-LB in front of me right now that is
fully stuffed with
8 rows of 9 MK4564N chips which should work out to be 512KB, which
matches the M8067-LA MSV11-PL description in the PDP-11 field guide.
I must have doubled things in my head twice. I was also probably
thinking about one of the dual-height cards being 256K, so a
quad-height card "must" be 512K.
The only way the memory could be doubled would be to
replace the 64K
chips with half as many 256K chips. ?Does the board support 256K
chips?
I am not claiming that 256K chips work. I used the right DEC part
number designations but misremembered the capacity. What I meant was
to take a board that is half-full of 4164s and to stuff it full of
4164s (which I did explain in the text, just with the capacity wrong).
Thanks and sorry for the mistake.
