http://www.jameco.com has these.
If you want quantity I would suggest http://www.rocelec.com
All of these parts are VERY old and will show up in various
places as surplus items for as little as $2 each.

The 8031 is in the MCS51 family

8255's are here

http://developer.intel.com/design/periphrl/datashts/INDEX.htm

The Intel 82C55A is a high-performance, CHMOS version of the industry
standard 8255A general purpose programmable I/O device which is designed
for use with all Intel and most other microprocessors. It provides 24
I/O pins which may be individually programmed in 2 groups of 12 and used
in 3 major modes of operation. The 82C55A is pin compatible with the
NMOS 8255A and 8255A-5.

The 2764 is an OLD Eprom and the 28F001 is a flash rom.
If you want to program these a good tool to have is from
Andromeda Research.

Hi,

Thank you for contacting Intel Technical Support. In case you were not
aware, the 28F001BX will be End-of-Lifed (EOL'd) early Q1'01. The
recommended migration path is to the 3 Volt Intel(R) Advanced+ Boot
Block(C3) product family.

A product overview and technical documentation on the C3 device can be found
on the web at http://developer.intel.com/design/flcomp/prodbref/297892.htm

A device data sheet and specification update on the 28F001BX can be found on
the web at: http://developer.intel.com/design/flash/
