Does anyone have a description of how to put 48K of memory in

the TRS-80 Model I without using an Expansion Interface?  I seem

to remember there being some published back in the old days

but can't find anything on the web.  I think it was done with 4164's

and a few pieces of wire wrap wire to jumper the missing address

lines.
