Subject: RE: Apollo DN 4500 looking to be saved from computer recycler
I have a vintage Apollo DN4500 including 19" monitor looking for a home
I also have all the HP/Apollo docs & software (although I doubt the
DC600A tapes would be readable)
I also have lots of DC600A tapes but my guess is after 10+ years the
media would have deteriorated.
Its in Webster (Rochester) NY. When I moved from Syracuse to St Louis in
1993 I hooked it up and it booted to the Apollo Domain/OS prompt. I didn't
bother to unpack it when I moved from St Louis to Rochester.

I beg your pardon. I live in the USA. However, in many parts of the world,
all telephone calls are metered.
This is *not* a USA-only list.

Hi.. is an Amstrad PCW (8512 I think) c/w printer of interest to
anybody. From memory, it's a CP/M machine, but uses stupid little 3" discs
(not 3.5") and originally came with a boot-up-into-wordprocessor disc...
It's currently in my neigbours front yard waiting for the bin men, but I've
a mind to rescue it. Apparently it works fine, just needs a new fuse.
It's in Salford, England, btw ..

Could be worse... this comes to mind only because as I read your message,
I noticed a new email coming down from one guy that I want to strangle.
I am on a mailing list for state surplus property so my Fire Deparment
knows when good stuff comes in. The guy that sends out the notices keeps
taking digital pics of the stuff, and importing them into MS Word
documents before sending them as attachments.
So he takes what would be a 50k JPEG, and turns it into a 2.5 MB word
doc... just so I can take a look at whatever he is hocking that day
(today it was a GMC dump truck).
Even on DSL, downloading a 2.5 MB file to look at one picture is annoying!

The way Acorn did that with things like the Master 128 Welcome Disc was to
make all the directory entries (on track 0) point to tracks between 5 and
9, and 20 and 39. Track 20 on a 48-tpi drive is where track 40 would be on
a 96-tpi drive:
96tpi 0 5 9 19 20 39 40 59 60 79
| | | | | | |
D |X| |XXXXXXXXX| | |
|__|_|____|_________|_________|_________|
| | | | | |
D |xxxx| |xxxxxxxxx|xxxxxxxxx|
| | | | | |
48tpi 0 4 5 9 10 19 20 29 30 39
So you need to format parts of the disk as if they're 40-track and parts as
if they're 80-track.
Start by formatting the disk normally, at the density-of-your-choice.
Next, write some dummy files that will occupy exactly tracks 0 (less the
directory area) to 4, 5 to 9, and 9 to 19, and then delete the dummy that
is in the space 9 to 19. You only need to do this for one density,
thankfully, as the object is just to get the right placeholders in the
space map. Then write the real data. Switch densities, format the tracks
that need to be the alternate density (Disc Doctor can do this), and write
the real files again. You may need to do the second set of writes with raw
disk access, as IIRC ADFS will "overwrite" a file by writing a new version
andf then deleting the old one -- which is not what you want because it
will use the wrong space!

We actually has a similar thing here... I had been trying to get DSL put
into the budget for months, and accounting kept saying no. Despite all
the added benifits it would bring us, they didn't want the $250 a month
price tag that I was proposing (this was early DSL, before you could get
it dirt cheap, I was one of the first in my area to get it).
So I was smart. I pulled out the last few months phone bills to show the
cost we were paying to have our "unlimited" dialup line connected all
day. It was connected to the network, and we were running a mail server,
so the only time it hung up was after 11pm, and then it went to
connecting once an hour to update the mail server, until 8am when it came
back up full time again.
Showing them three months of $450 line charges got my $250 a month DSL
put onto the budget with no further complaints.

Maybe they are, but from what I gather, that is not unusual outside the
USA.
Even here in the USA, if you are on a dialup connection, and calling from
a business... guess what, you are probably paying by the minute. Most
business lines in the USA are billed per minute of connect time (or
worse, by the "message unit").

I had posted a while back about wanting a Toshiba 3100 laptop.... I think
someone replied with one I could have, but I can't find that email anywhere.
Long and short of it is I need something along the lines of a 286 or so,
that is small enough to fit easily on my electronics bench, and has one ISA
slot, preferrably two. I was thinking the Toshiba 3100 was pretty close to
this.
Can the original person who responded please get back to me, or does someone
else have something close? I'm wanting to put an HP-IB card in the unit to
interface with my test gear, and possibly a wireless card or at least an
ethernet port (I could get the ethernet port with a zircom parallel port
adapter that I have)...
Thanks!

Eric,
Yes, you are correct. My fault. I've always mixed up MOSTEK and MOS Technology. It seems I remember that
the MOS Technology folks left Motorola because of the way the 6800 was progressing, but that could be a faintly
remembered rumor also.
MOS Technology was responsible for the 6550 ram. I seem to remember having a book from 82 or 83 from
MOS Technology somewhere.

Yes. Thanks for letting us know. This has been common practice
since forever in Europe, and many other parts of the world.
