This directory describes a variety of ROMs for DEC equipment, originally 
made available by Pete Turnbull.

Please note that these ROMs contain software which may be subject to
copyright.  They are provided here as a convenience to collectors of
classic computers, for use only in repairing machines and peripherals.

They are not here for free upgrades, and any misuse may result in
them going away.  If you are the owner of the copyright on any of
these images, and wish them to be removed, please contact me.

Contributions of additional DEC ROM images are welcome.

DEC ROM part numbers all begin with "23-".
The next three digits+letter+digit are the ROM number, eg "123E2"
In some parts lists, numbers are shown with a trailing "-00".
However, my parts microfiches show hundreds of ROM numbers, and only
about eight have digits other than "-00" so in general it's redundant.

The final letter+digit gives the general ROM type and size:

A1 means   32 x 8  16-pin, eg 74S288, MMI6331
A2 means   256 x 4 16-pin, eg 82S129, MMI6301
