A quick question. I'm buying a used C128 and 1571. How can I tell if they have updated roms? Are most of the C128s and 1571s the current revision? Is there a peek I can do to tell? Any help will be appreciated. Thanks! Warren Tustin warren@hp-col.hp.com

After resetting the system, throw a single-sided diskette in the 1571 and ask for the directory. If it takes forever to catch on to the fact that the diskette is single-sided, then it's an old ROM 1571. Confirmation: write a HUGE SEQ file. If, when side 1 is full, every sector write induces a seek to the BAM track.

Thanks! > > Warren Tustin warren@hp-col.hp.com To find out which version of roms in the C= 128 type this line. bank 15 : print peek(dec("7ffe")) 0 is the older version. 1 is newer version. I don't know the difference between them. piskac@en.ecn.purdue.edu
