I found these manufacturer names and numbers for the chips in the Jam
Manual on page 22. I don't think they have been posted before so here goes.
Hope it helps.

Motorola         MCM54400AZ

Hitachi             HM514400AZP

NEC                 D424400V

Fujitsu             MB814400

Mitsubishi        M5M44400L

Micron             MT4C4001JZ

I got mine from Chips for Less at 1-800-820-6009. I think they charge about
$110 nowadays. Just say you want the RAM for the Jam Man and they'll know
exactly what you are looking for. According to others on the list you can
probably get it cheaper if you look around, but if you are having trouble
finding it, they do have it.

Also since there have been some new folks subscribing to the list and
others talking about buying up the cheap Jam Man units that are still out
there, I thought it might be good to repeat some info regarding proposed
software and hardware upgrades to the Jam Man that I heard about. Back on
January 3,1997 I spoke to Bob Sellon at Lexicon.
Here's what I posted to the list:

I have not heard from Bob since so I don't know anything new, but if you
haven't emailed him yet please do so.
I also gave Bob our email address and told him to post directly to the list
if there is any news.
