Subject: Solidisk 1770 Upgrade kit

I don't want to cause too much confusion, but I thought that Solidisk
produced at least 4 1770 DFS kits. 2 Pre Acorn (1770) DFS kits:

177O           Issue 1 Pre Acorn (1770) DFS
1770+8271      Issue 1 Pre Acorn (1770) DFS

After the BBC Micro Plus was launched Acorn produced the 1770 DFS for
the standard BBC Micro and Solidisk produced issue 2 1770 kits:

1770           Issue 2 Acorn (1770) DFS compatible
1770+8271      Issue 2 Acorn (1770) DFS compatible

I'm fairly sure the jumper settings were different between the issues
also. I'll try dig out the manuals, although if you have issue 2
1770+8271 I'll check it against my Beeb.
