BTW, I've used 6821s & 6520s interchangeably
as well without problems.
I only mentioned it because someone either here or on the CBM Hackers
list said they had problems substituting a 6821 for a 6520. Since I
have tubes of 6821s and a small pad of 6520s, I was happy to verify
the substitution (I have, in the meantime, traded a tube of one for
a tube of the other across the pond, so I'm all set with both).
And I did find some extra DL1416s, although that
won't help you with the
unit that doesn't have a display board
I'd still be interested in them; I was considering making a replacement
board that matches the original since I _do_ have the PIAs and that would
be faster than engineering a replacement. I found a potential source
of original (used) parts, but their web page is broken and they don't
Would you have 10-12 DL1416s? That would give me enough for two
display boards and a spare or two for the future.
Right now, my "spare" time is all focused on displays anyway - the
LCDProc project (http://lcdproc.omnipotent.net/
) is closing in on
a new point release and I'm trying to debug a development environment
to be able to add support for some new display hardware (PD3000 "pole
displays" like you see attached to cash registers/tills).
