stable but YMMV

This question came up on the HP LX palmtop list. Are there any emulators of
the C64 or the HP48 that will run on the HP200LX palmtop (which has CGA
graphics, and 80186 CPU, and MS-DOS 5.0)?

Full books but stay with families IE: VAX, PDP-11, CPM S100 as a

Yep same for CRTs, though I do have H19, VT125, VT320, VT340. Then
again It's DEC family skewed plus CPM so it works.

Nope, compact it to denser media that can be recoverd to whatever is
needed. Again within a family one program runs on many.

Or trade it off for that relly important item(s).
My problem is I have three realted hobbies, Computers, hamradio and
electronics Homebrew (autoconstruct for the EU folks). They overlap and
radio/homebrew instigates the "junquebox" where all good resources are
found.

There are some non-AMP equivalents that don't seem to be made quite as
well, perhaps you had some of those? I've cursed those on occasions when
I've had to make the opposite-to-normal gender of power connector.

AMP changed the numbers at some time in the last few years, but I think
some of these may still be correct:
female contacts AMP 163304-2 (18-20 AWG)
female contacts AMP 163306-2 (14-18 AWG)
male contacts AMP 163305-2 (18-20 AWG)
male contacts AMP 163307-2 (14-18 AWG)
AMP used to have a pretty good website. A bit graphics-heavy, and a little
tedious at times, but al the info was there. Tried that?

Funny you mention that, I was looking for the same thing the other evening.
I can find the pins and shells but the biggest two-row shells I can find
easily are only 8+8. I want 20+20, of course. And I can't find those
cable grips at all...
I did find a very similar product (there are lots that nearly fit the bill
but this looks closest) made by Methode. They do 20+20 in their MEMTF
series that look very like black Berg ones, and the female crimp "pins" are
gold-plated like the better Berg ones. Still no cable clamp, though.
Fujitsu so something similar (M100 series), and there's a cable clamp, but
it looks kind of like a squashed D-connector shell -- not what I want for
my BC101V cables and oters that enter from the side of a board.
Harwin also do a range, called "C-Grid III", you'd want the 90142 series
(dual row).
I used to get BERG (DuPont, now owned by the Framatome Group, FCI)
connectors from a company in the UK called Electrospeed. Sadly, they no
longer seem to have the right connectors in the catalogue, but I found the
part numbers in the Newark catalogue -- which might be more helpful to you.
They're also in the Farnell catalogue.
The housings are "Bergcon" "Mini-Latch housing, 65043-series double row,
0.100" centers":
Newark Berg
part part rows
89F4606 65043-035 2+2

You can also buy the daisy chain jumper wires on reels. Remember those?
Used to make up the vital link on the BC01V, the link from Tx- to Rx- on
DLV11-J's, and for loopback plugs. A snip at UKP166.36 per reel. The
"lightweight rugged handtools" in two shpaes and five exciting sizes, range
>from UKP385 to UKP503. Thankfully the rest of the range, the connectors
themselves, is more affordable! Still no cable clamps, though.

Found a really nice PDP "Micro" 11/73 at the scrap yard today. I don't know
the designations but it's in a rack mount box 5" high and 24" deep. I don't
usually bother with DEC stuff but, it was real clean and the price was
right.
The system has a hard drive, dual floppies, and 4 serial ports (plus
console) on the rear panel. I hooked up a terminal and am able to talk to
the system. However, when it tries to boot but gives a message:
"DEVICE TT001: Not in configuration"
"RSX 11M V 4.1 BL35E 1024K mapped"
It stops at that point and won't go any further. I can ^C and get a "MCR>
prompt" and talk to the system but it won't *do* anything.
Am I doing something wrong or is this the expected behavior when the OS is
broken?
Thanks,
SteveRob

That's because you need custom ones for each case design (no simple PC
plates will work), but the Mac will use stock PC parts for the most part
(when it comes to HD and CD drives... all bets are off for any other
parts prior to the iMac days).
Since you can use a stock PC CD drive, many people did... PC drives
naturally don't ship with the special bezel needed for a mac case. You
have to buy it from an apple dealer (because apple doesn't like to sell
things to the public). That means you pay Apple prices AND the Apple
dealer markup... that makes them VERY expensive (you can expect to pay
$25+ for a new bezel for most macs). That is when you can even find
someone to sell them to you (the local CompUSA, which prior to the Apple
Store opening down the road, was the ONLY authorized apple repair center
in the area... and they couldn't be bothered ordering you a bezel...
tried once... they game me shit for even asking... then finally agreed to
order it and call when it came in... a month later and many calls asking
the status, I gave up).
Even going to the online parts dealers will nail you for serious costs
(have you looked at any recently... MacResQ which tends to be the
cheapest, will ask $30-$40 for a bezel)
As a result... you find many home upgraded macs that are missing the
correct bezel for the opening.

That's somewhat Cisco-specific, if those are the standard colours. The
standard colours for 8-way flat cable (in order in the cable) are
1 grey (some cables use white)
2 orange
3 black
4 red
5 green
6 yellow
7 blue
8 brown
However, that's not always used in pre-made sockets. I have three
different ones on the desk beside me. One goes blue, orange, black, red,
green, yellow, brown, white, for example. That would give you the
following pinout:
RJ45 pin DE9 pin signal
white 8 9 Ring Indicator
brown 7 6 Data Set Ready
yellow 6 2 Transmit Data
green 5 5 Signal Ground
red 4 5 Signal Ground
black 3 3 Receive Data
orange 2 4 Data Terminal Ready
blue 1 7 Request To Send
It would be much more usual to pair RTS with CTS (DE9 pin 8).
One of the most common ways to wire an RJ45 for serial, are to wire the
centre pair both to ground, with TxD on one side and RxD on the other.
That way, if you turn the cable upside down you (as in a normal flat
cable, one end is wired opposite to the other) you cross over RxD and TxD
without losing the ground. TxD is pin 3 on a PC-compatible DE9 serial
port, RxD is 2, and signal ground is pin 5, so that's fine. In a flat
cable, the pairs start from the centre two wires, and work outwards to both
sides, ending up with the 4th pair being the two outermost wires.
But most systems that use this scheme put DTR and DSR (or occasionally DCD)
on the next wires out from the centre (3rd pair), and DTR is on DE9 pin 4
(orange, OK) and DSR on pin 6 (brown, no I don't think so) and DCD on pin 1
(which Cisco obvioously doesn't use). The reason for putting DTR and DSR
(or DCD) on the next two wires is again for the crossover effect. That's
what DEC and several other companies do.
Similarly, some systems put RTS and CTS on the outermost two wires.
Looks like Cisco are using a non-standard colour order (or your RS adaptor
is) but otherwise following one of the common wirings for flat cable
(except for RI and RTS!).
Of course, lots of people use UTP instead of flat cable. Then one way to
start off is to put TxD and corresponding ground on pins 1+2 (which is one
pair) and RxD and corresponding ground on the next pair (3+6). That way,a
normal UTP crossover cable (one end wired to TIA 568A and the other to
568B) crosses things over correctly. That leaves 4+5 and 7+8 for other
signals, usually unused but sometimes DTR+DSR and RTS+CTS (to keep each
pair of signals in a single pair of wires, but it makes crossover cables
"interesting"). DEC do it like that, they put 1 and 3 on the RJ45 to
ground (actually Tx- and Rx-), TxD and RxD on 2 and 6, DTR and DSR on 7 and
8. Sun do a similar thing (but not quite the same).
There is *no* standard for this, and I've found at least three common (and
largely incompatible) wiring schemes, and several more obscure ones
(Cabletron, Xylogics, ...)
