is wd-40 a good idea? I was thinking isopropyl alcohol
might not penetrate as well or quickly. And Im not
paying another tenner for that radio shack stuph,
especially since I already have a can of it *somewhere*.

Suppose you have a dectape and for whatever reason the tape on the reel is
destroyed. What currently-available tape can be used on the reel instead?

This sounds like an Apple Firmware card with Integer
BASIC installed. With a flip of the switch and a
system reset your Apple's onboard firmware will be
replaced by whatever is on the board.
A very useful expansion in the 48K Apple world when
their was still a good mix of Interger and Applesoft
BASIC programs floating around. It was largely
superseded by the 16K RAM Language card.

Any chance someone has a spare? :-) I recently got my hands on an e4k,
but the peripheral power supply seems dead. I took it apart and saw
that the fuse is good, haven't had a chance to test its components, but
thought I'd ask.
My only claim to being *possibly* on-topic is the age
of the article (1974) and the fact that it inspired
many of the early phoneme-driven speech synthesizers
(Votrax, etc.).
Does anyone have access to a suitably good engineering
library with a copy of:
McIlroy, M D, "Synthetic English Speech by Rule",
Bell Telephone Labs, CSTR #14, 1973 (though I have
also seen it referenced as 1974!)
or:
Ainsworth, W A, "A System for Converting English Text
to Speech", IEEE Trans Audio & Electroacoustics AU-21 #3
pp 288-290, 1973
The former is far more interesting to me than the
latter :-(
(sigh) There are *some* advantages to being a student
(though those days are long past, in my case!)
I can try my local public library to see if it is
available via ILL. I guess I could also try the local
university's engineering library.
Thanks!

Out of interest, what's the market for unused, still-sealed magtape (9 track,
2400ft*, 6250bpi) like? I got hold of a few reels the other week and can't
decide whether we should just put them to use them as/when necessary, or use
them to raise funds for other museum projects...
* well, near as I can tell. The scale on the reel goes from zero to 2000 in
increments of 400 and is some way over the 2000 mark; I'm assuming it's feet!
(did anyone ever sell magtape > 2000ft that *wasn't* 2400ft in length?)
thanks

Out of interest, are any particular types of environment harsher for IC leg
corrosion than others?
I've not seen that much corrosion about, other than surface stuff that can be
cleaned off - but I'm currently trying to get an old Acorn System Three
running, and about half the ICs in it are leaving some of their pins behind
when removed from sockets as they've corroded right through :-(
The PCBs are otherwise in very good condition, but for some reason a lot of
the chips (most notably DRAMs and LS logic) are in a right state, and it would
seem that *something* has been eating away at them - yet *some* of the ICs are
totally corrosion-free (as are all the passives, IC sockets etc.)
Luckily all the dead parts (so far!) are ones that I've got spares for, but
it's just made me wonder what's accelerated the decay in some of the chips but
not anything else (unfortunately I only picked this machine up last week so
don't know its storage history, but I can ask the previous owner). Judging by
the pretty good condition of the rest of the machine, I wouldn't say that it's
been in a particularly high moisture environment.
cheers
