A friend will soon be receiving a TC2048 made by Timex of Portugal which he
wants to use in the US. Replacing the DC ps is no problem, but the composite
video out was designed for a 50 Hz PAL TV.
What's the best way to hook a US TV or monitor up to this beast?
Thanks,
Glen

What connectors does it have?

There used to be a mod for the UK 48k Spectrum to convert
it's RF-out to a composite signal that could be viewed on US
composite monitors. I'll have to poke around and see if I still have
it somewhere. It may at least provide ideas on how to do a similar
thing to the 2048.

It should be possible to tap off composite video at
the input to the
modulator can. It'll still be UK standard (50Hz vertical) but many
composite mono monitors will display that if you tweak the verical hold
knob. Am I correct in assuming that this is a monochrome output machine
anyway, so the colour encoding differences (NTSC .vs. PAL) are irrelevant?
He said a TC2048. I wonder if he meant 2068, which *is* colour, unfortunately.
It seems that most American TVs are not PAL friendly. I wonder why it's so
much easier to get an NTSC/PAL set in the rest of the world than it is here.

If they had access to a video card such as ATI's
All-In-Wonder that provide for both inputs and outputs, it should be
possible to input a PAL signal and dispaly it on an NTSC screen,
though they could also just view the input in a window on thier
screen as well. Wouldn't something like this be possible on the A/V
equipped Mac's as well?

I use a Formac ProTV and can view PAL on that (makes sense, since Formac
is a German company :-). It should be possible on standard A/V Macs also,
like the 7600.

New subject: HP 85 Question
I have an HP-85B with I/O ROM, the HP-IB interface and
an 82901M 5 1/4" flexible disk drive unit (there are
address switches on the back of the disk drive - now
set to 000)? I want to access the drive from the 85B,
and believe that I have all the necessary parts, but I
lack the I/O ROM manual which, as I understand it,
describes the extended BASIC commands (such as CONTROL
x,y;a). So, I have a question:
Once I hook all of this up, how do I access the disk
drive, read from it, save to it and format a diskette?
Thanks.

I should have also mentioned that I have the Mass
Storage ROM as well, which I assume may also be
necessary.

For most basic operations you don't even need those ROMS.
Ok, here's some info:
file names have the form: "file:msus", where
msus=mass storage unit specifier. Typical msus are:
":D000" electronic disc
":D700" mass storage on HPIB bus (interface code 7)
with HPIB ID=0, and unit number = 0;
":D910" mass storage on HPIL loop (interface code 9);
with HPIL address 1, and unit number = 0.
":D751" If you have an HP82901M dual HPIB floppy drive
at HPIB address 5, this is the msus for the second
floppy.
":T" The msus for the internal tape drive
Now, some commands
MASS STORAGE IS ":D000" - defines electronic disc as default msus
COPY "MYFILE" TO "MYFILE:D710" - copies "MYFILE" in default
msus to
to an HPIB mass storage device at
HPIB addr = 1.
INITIALIZE "MYLABEL", ":D720" - formats HPIB drive w. addr=2, using
standard LIF directory size and
interleave, and with a volume
label "MYLABEL". You can later refer to
a file in this volume as "MYFILE.MYLABEL"
ERASETAPE - format a tape
MSI ":D710" - equivalent to: MASS STORAGE IS ":D720"
CAT ".MYVOLUME" or CAT ":D720" both work.
DISC FREE S,T, ":D720" stores the number of free records in msus
"D720"
in variable S, and the number of records in the
largest contiguous free area of ":D720" in
variable T.
MSUS$ returns the msus of the current MASS STORAGE IS device
VOL$ returns a six character string indicating the volume label in the
current MSI device; VOL$(":D700") you guess it.
This should be enough for you to play for a while.
Regards,
Carlos.
