Compaq released a replacement address decoder chip that would allow
replacing two rows of 64K chips with 256K chips to go to 640K. They're
unobtanium now, of course, so you have to waste a slot on a memory card.

You forgot to attach her message and/or address.
AFIK there were no options for the original Portable. I've had several
and read the manuals and I don't remember hearing of any options. But it's
been a long time and I could be wrong. I think somewhere I still have an
original brochure and some manuals but don't ask me to find them. I can't
find half the stuff that I thought I knew where it was.
IIRC they were 256k, 8088 CPU and dual DS disk drives and that was it.
The Portable II was 40% smaller and lighter and had 640k of RAM. I think
a
hard drive was available in the P-II but I don't
know if that was from the
factory or a third party job.
