Hello Lewis:

Leider nicht...  I have some major tasks that conflict
with the Warpstock schedule this year.  Also, I have a
T30 but was hoping that the card that worked in the T23
would do so in the T30.

Unfortunately, I have one of the T30s with a defective
memory slot.  I must send it in for depot repair and
can't be without it.  Right now I have a 512MB DIMM
installed.  It rarely comes anywhere close to swapping.
So, I'm not sure how much better it will be with a GB
of RAM.  By the way, I have the same processor.  It's
quick enough with most tasks but underpowered for VPC.
Most of my comparisons are based on using PMView and
WP51DOS, two programs that I consider pretty nimble.
The fact that I see any difference gives me pause.  I
can understand the effect of a much better video card
in my PA2013.  The WP gap is a little more difficult
to explain.

It's crazy, isn't it?  It's like the relative cost of
old RAM.  I'm looking at the possibility of moving up
to a T40 once their used and refurbished prices come
down.  Right now, I'm waiting for my Intel SE7501WV2-
SCSI320 board to arrive while I try to find a pair of
cpus and at least 1GB of memory that I can afford.
It should allow me to get some work done, at least
when I'm at home.

Take care.

Best Regards,

- Mark
