Toby: The modern smt chips are only designed to be machine placed and soldered. I cannot even see the new sized resistors and capacitors [noparse]:([/noparse]
That is reality and unfortunate for us hobbyists. Our volumes are too insignificant to count and all modern electronics require as small as possible. Do you remember the "brick sized" mobile phones. SMT has brought us the modern pocket size.
JMH: I am asking the question about size 512KB or 1MB and why ? I have decided not to produce both.

1) Cost
2) I have yet to imagine an application of Prop + RAM that needs a MEG
3) If it make you design simpler, more elegant that's good
4) If it enables some, as yet unspecified, feature that's good.
Actually what do you want the pin for?

For me, the past is not over yet.
There is basically no cost benefit in reducing to 256KBytes and CPM3 will use at least this with banked memory. Also I see a 8088 PC with 512KB as a good proposition also. I know the clones had 640KB, but IBM PC's did not at that time.
So I will take that as a yes to using 512KB
Hopefully I will be able to show my results in a week.

Yeah, we need to collect these algorithms or source code:

Very neat and very impressive. In terms of 32-bit data transfers ( I'm looking at executing code from XMM rather than just getting the data ) - PASM 20 MIPS, LMM 5 MIPS, XMM 2 MIPS which isn't too bad, although that considers instructions streamed in and not any random adressing overhead.
