Forgive me, my ignorance, O Wise One, but what is this Haddock?

As Tony pointed out, 50/60 Hz shouldn't be a problem.
HOWEVER, it should be pointed out that the transformer must be capable
of carrying the power. I used a 10VA transformer to power the one or
two devices that had 240V only. To run monitors and things, you'd need
100VA or so. Transformers do exist for just this sort of purpose, upto
about 2kVA, but V. heavy!
(Rule of thumb for switchmode power supplies - Look at ower consumption
and assume 1VA = 0.6W)
Finally, a tranformer designed for 60Hz must be derated to a lower
VOLTAGE when used at 50Hz.
I hope that hasn't got you all too confused.

Assuming one got a wire recorder working, what is the print-through
situation like? I'd have thought not too good...

Hey, just in case anyone's interested in HP calculators there is a red dot
model of the HP 35 for sale on Auction Web. For the ones of you that don't
know what they are, the red dot is the very first batch of HP calculators
that were ever produced by HP. They're very rare and you almost never see
one for sale. If any of you have one, I'LL BUY IT!
The URL is

I'm not the seller.

Browse some C-64 web pages, you'll find lots of info about this.
There are one or two emerged-standard parallel to DIN cables like
"X1541" that you can easily craft (given the right connectors -
I got lucky and found the right DIN in the junk box) that connect
your PC printer port directly to the 1541. Works like a charm.
I've also used a freeware utility on the Amiga that requires a
tweak of the drive speed motor on a 5 1/4 drive, and that works
OK, too. The 1541 is better, though, but you'll find a lot of
bad sectors and out-of-spec disks on the C-64.

Hi!
I think someone on this list is a System 80 expert, and I am hoping I can
find them. :) I just picked up a System 80 with expansion box and disk
drives, but I'm having some trouble. When I power it up I either get
gibberish on the screen (the usual stuff you get before the ready signal)
that doesn't go away, or, when I switch the box off,I just jump to BASIC.
This happens with or without a disk in the drive. I tried another System
80, and that one didn't seem to notice the expansion box at all - it
always went into BASIC, whether or not I had the box switched on.
None of the manuals seemed to have anything useful to say, but I suspect
that either I am being really stupid and failing to do something basic,
or something is broken somewhere. Any ideas?
Thanks heaps,
Adam.

Same here, as long as it's portable, AND made by GRiD Systems.

Check with one of the many Atari dealers out there... Best Electronics (San
Jose) has just released a new catalog that is also supposed to be an
excellent reference. Do a search on them and you should find it; several
other vendors (Like B&C) also sell the best catalog. You could also try
Computer Direct (I think) in Canada; they're a big dealer.
