ROM chip.  I hope you did not blow you ADOS chip.  I believe you want
to buy the DOS Adapter board at http://www.cloud9tech.com/, to put in
the 24pin socket to convert the 28pin ROM to fit in the 24pin ROM
socket.

The Controller I have as 2 ROM Sockets the 28 PIN ROM installed says WDC'83 with a chip number WD1773-ph. The 24 Pin ROM is a Tandy Chip number SCM92128P. When I replaced the 28 PIN ROM with the Ados chip I bought it comes up with the standard Disk Extended Basic screen. (I put back the original ROM chip and the controller works fine so I did not destroy anything)
