Hello everyone, what I once did in the print form, I am now starting as a "radio" show. If you are not familiar with podcasting, it is essentially an mp3 talk-show (usually). This can be downloaded to your iPod or mp3 player, or simply listened to online from the below link. All that is needed is QuickTime.

I hope my work can be an enjoyable and useful addition to the hobby/community.
Thanks, David Greelish

Yes, a bunch. Are they rare around there?

Convenience, I suppose, to eliminate disk swapping / floppy drive wear /
grease problem. My 9153 continues to function, and I am religious about
cleaning the floppy drive. And using new or newish floppy disks.

True enough, but you don't have the look & feel or the C64 key labels & layout;
I think the idea is to use a defunct C64 and use it as a keyboard for the emulator.
In fact, since it's a snap to upload different conversion tables into it you could use
it for several different emulators of systems using RS-232 or matrix (and probably ASCII as well) keyboards, all on the same computer; just plug in the appropriate
keyboard, upload the matching table and it's just like the real thing but without the
"real" hardware.
Also I thought I'd mention it for the RS-232<>PC keyboard option, something I've
found useful for several applications; interfacing to otherwise inaccessible
systems and replacing terminal keyboards are two examples.
Finally, the folks at Hagstrom have always been friendly & helpful and I thought
I'd give 'em a plug :)

Hi folks,
I was wondering if anyone has any data on
the Dymo Labelwriter 330 Turbo?
I would like to use it with my Amiga 600, but
alas Dymo haven't made a driver for it!
I tried writing to them attempting to get some
technical documents on the printer with no
luck.
Has anyone attempted to write (or written)
a driver for it for retro computers?
Does anyone have one and (sorry!) a PC/laptop? I nee
d some kind person to intercept and
retrieve the data sent from the PC to the
printer when printing a blank label and a
completely black label, so I can compare the
data between the two.
Regards,
Andrew B

Thanks to tremendous help from several folks I've isolated my formatting
problem.
Turns out to be a hardware issue with the DY1: drive. I've tried
cleaning heads etc. The read/write boards are fine ( I swapped them
with my Decmate I to check).
So now I need a single drive for an RX02. Any idea's of a source?
Many thanks!

Sorry for the off-topic posting.
I've got some old Sun and Intel-based equipment that I'd like to get rid of.
I'm not sure if they are of value to anyone (if so, email me and I'll let you
know what I've got) but I was wondering if anyone had any ideas or
information on places to dispose of it all.
Things range from a Sun 17" monitor to misc peripherals to towers. I'm
planning to put an ad up on, say, craigslist saying "if you want them come
get them" but on the chance that no one does, was looking for some pointers
on proper disposal. (recycling, donation, give 'em to Goodwill, etc).
Cheers,
Chris

Well, you can maybe still buy Quckware PDP-11 boards, so there are still
new PDP-11 systems shipped. http://www.quickware.com/
Also, I'm not sure what I would call Strobe Data's Osprey systems...
(http://www.strobedata.com/)
But yeah, I think Mentec have stopped selling hardware.
None of the CPUs mentioned above comes near the PDP-11 in longevity,
even though they are long runners.
The best candidate is maybe the Z80, since it's still in production and
going strong. Not sure if the 1802 still is around, both the 1802 and
Z80 came years after the PDP-11. The PDP-8 systems stopped manufacturing
quite a while ago, and while they started before the PDP-11, I think the
PDP-11 have passed them now.

I'm relearning RT-11 on an 11/23 I was kindly given (thanks David!).
I'm having trouble with the RX02 drives. I can boot RT11, and .format DY1:
About 1/3rd of the time I get an error while formatting, this is on
known good 8" SS/DD media that has been extensively tested on a CP/M
system in both SD and DD modes.
On media which does format fine, I get gobs of bad blocks using
.initialize/badblocks DY1:
The only media that seems to work fine is "real" RX02 media.
Is the RX02 incapable of formatting it's own media? Is there a common
hardware problem that I should look for? Filter caps? Clean the
stepper motor?
Many thanks.

Hi Tony

HP BASIC is quick to put together and powerful. The documentation is good
and available (as you've seen, or got). I think the documentation was one of
HP's strong points with these machines.
HP Pascal gives you the speed, but you'll definitely need more memory ...

My programming career started with HP9816s' with only the 256K on-board RAM;
that was using Basic 2 originally, then Basic 3. And we got by - the
company didn't want to spend any more than it had too! That was in civil
engineering & construction where we were able to put together costing,
critical path planning, and some envelope & pre-stress design software.
Whilst it is certainly constraining, so you'll probably be ok with one
add-on RAM card for a lot of things. Later on, I got involved with a land
surveying package, which besides being able to do a multitude of cadastral
calculations, included a fairly comprehensive CAD facility. That definitely
needed more RAM, and was standardised with a 1MB add-on card. For all above
software, the only IO we did was RS232 for HPGL plotting, so only needed the
built-in port.

Haven't seen or heard of this.

Probably 913x/915x spare hard drives, unless you're able to get the drives
