Well, it could just be that I missed it.  To be truthful, I only read those
chips which struck me as being OBVIOUSLY roms.  That is, they were EPROMS of
either the 27XX or 271XX series and had stickers on them.  I'll take another
look when I swap the power supply.  I also bid on some 8" disks on eBay.  I
may actually get some good use from this thing yet! :)
