I heard last night that Netpliance is making modifications so that people
can no longer do this... they are apparently losing a LOT of money selling
the machines, having expected to recoup it in the service charges...
Can someone confirm this... and maybe confirm the change that they
have done (which I understand is simply removal of the cable connector
for the drive).
Oh, and supposedly back-ordered units will have the mod...

Yes, it does mean "ground". I translated it with a little help from a
colleague (thanks, Karsten!) but Wim beat me to it...

I also had problems with a IBM 0661 disk. I was unable to get it to 512
byte sectors from 524/sector using either RZDISK (VMS) or TEST 75 on my
3100-M76.
I was able to format it on my RS/6000-220 using the diag program's service
aids/disk media service aid/format disk option in AIX.
Although there were no command parameters and no information from AIX on
what is was doing, when it was done the disk was reformatted to 512 bytes
and I was able to use the disk on the VAX and later make a spare bootable
unix system disk on my DEC mips machine.
Perhaps the IBM format also turned off the "target initiated sync
negotiation" for AIX in the saved config code page in the drive.

Same here since is was changed to say "against the terms and conditions".
To say the other is patently stupid.

Well the bios is AMI 4.51 and that easy to get, the connector is no big
deal and is the flash was converted to plain rom the introduction of an
IDE device defeats it. In fact from reports the interoduction of TWO
IDE devices elimintes it.
The rumor mongers have to do better.
I really want dos/MYZ80 running on one.

I think there are tabs in some of the vent holes on the side. (at least,
I seem to recall that's how their tape drive was. Sneaky.

you didnt give enough detail to say whether its an apple brand external scsi
drive which fits perfectly under a plus or se. if it is, there are tiny slots
in the sides that you have to push a screwdriver into to release some tabs.
very tedious, but no easy way to do it.

Bell & Newell's out of print book about computer architecture runs through
both architectures (as well as many others). Unfortunately, I don't have a
copy so I can't be more specific. I can't even find the photocopies I made
of this and other information (I have a couple of large three-ring binders
chock full o' architecture descriptions ranging from EDSAC to modern stuff;
but my office has moved a couple of times since then, so I've misplaced
them).
> Can PDP-1 software run on a PDP-4?
No. The PDP-4 was designed to be able to use PDP-1 memory and I/O devices
(IIRC), but the instruction set is different. The instruction set of the
PDP-4 is essentially that used by the PDP-7, PDP-9, and PDP-15; the
Bell&Newell book (IIR the source C) claimed the primary difference between
the PDP-4 and the PDP-7 was that the PDP-7 used ASCII I/O devices while the
PDP-4 used a six bit code.
The true mystery is, of course, the PDP-3. It was allegedly a 36-bit
version of the PDP-1. I've seen one source that had a drawing of the word
format for the PDP-3, but no other information (the source was an "encyclopedia
of computers" circa 1960 that was composed of two-page descriptions of each
machine which appeared to be taken from the marketing literature for the
machine. The PDP-3 was listed, a word format was given, and a couple of
trivial benchmarkish statistics; time to perform an add, IIRC. I have a copy
of the blurb in the aforementioned three-ring binders which I can't find).
Rumor has it that a DEC customer built a PDP-3, but DEC never did.

Hi folks,
I'm looking to acquire two models of terminals made by Hazeltine,
the 1500 and the Esprit, in good operational and cosmetic condition.
I used each of these for a long time many years ago and I'd like to
keep one of each for sentimental reasons. Does anyone on the list
have one that they'd be willing to part with? I'm willing to pay a
reasonable sum. Please let me know. Thanks!
