I have been looking at my DECmate II recently. I got an Italian version of
WPS 1.0 for it and that works fine, except that I don't have an Italian
keyboard so finding some of the characters is a bit tricky. :)
The machine came with an RD51 hard disk. I can't many references to MFM
disks in DECmate IIs. The disk will sometimes spin up and sometimes remains
motionless. I checked all three of the Darlington transistors on the drive
board and they seemed fine (I checked them out of circuit). However, unless
I have any really persistent problems getting the disk to run, I am not
going to bother trying to make it start reliably.
My main question though is this. From what I can see the WPS software does
not access the hard disk, the manual I have does not mention hard disks. I
executed the function for listing files and it said it found nothing,
whether that attempted to access the hard disk or not I don't know. Should
WPS be able to access the hard disk? Might it have been a later version that
used the hard disk? If not, then would one of the other OSs for the DECmate
II be able to access the hard disk? I don't have any other OSs for it
though, does anyone know where I might find copies?
I also have a graphics option board for the machine, which software actually
uses this option?
Any recommendations for how best to image RX50 diskettes? I want to preserve
the diskettes I have.

Rob

Since I doubt I'm the only one on the list with failing eyes. I thought
I'd ask about monitors. Now, I'll preface this with the fact that I have
some macular degeneration in my retinae. So, I prefer lower resolution
monitors (so that fonts can't get too tiny). I also prefer as many NITs,
CD/M2, candlepower, or whatever you like to call "brightness" as I can
get (again, it's my eye issues).
I was curious what folks liked? Since I mess with a lot of consoles and
still occasionally play with the Amiga or MiST, I like to have the option
to do composite video. Keep in mind is all geared toward retro users. I
konw there is "better" gear than this, now.
Favorite LCD Monitor line: NEC Multisync, Dell Ultrasharp
Favorite CRT Monitor line: Iiyama (Sony Trinitron as a runner up)
Favorite Video Resolutions: 1280x1024 4:3 and 1280x720 (16:9)
Favorite display Devices: SGI O2 CRM graphics, The Voodoo3 for PC, The
VillageTronic Picasso IV for the Amiga.
Favorite retro NTSC/PAL Video capture devices: SGI Indy built-in
composite/s-video, SGI O2 A/V option, Amiga Newtek Video Toaster Flyer,
Quadra 880AV option for Macs, and the Matrox Rainbow Runner for desktop
PeeCee.
Favorite Retro Sound Cards: Gravis Ultrasound for PC, Sound Blaster emu10k
("Pro" PCI cards), Amiga Studio 16, SGI DM8 for SGI/IRIX, Pro Audio
Spectrum for 68k macs.
If we are going further back to the 90's I'd say I liked 640x480 for all
the great artwork done in that res on various platforms and MCGA 320x200
for games (mainly because they finally got 8-bit color that way).
The biggest downside to the NEC monitors is that few of them support
composite or S-Video. The biggest upside is that most of them perfectly
support sync-on-green. Another good monitor in terms of flexibility for
retro use is the Dell 2007FP Ultrasharp. It's 20" I think, but has a
plethora of ports and features.
I also own a Sony Trinitron PVM-20M2MDU medical monitor for my Genesis,
SNES, and Neo Geo MVS conversion system. It's around 50 pounds (22 kilos),
but at 20" it's small enough to keep around. It's tough to beat these for
any type of non-HD video.
I'm getting interested in projectors, too. However, I'm doubting I'll find
one that's bright enough and will do all the video modes I want (ie.. mix
of sync-on-green with composite etc..)

I have a PCP-11E board, which I'd like people to comment on, perhaps
point me at some documentation if you know of any. Google is saturated
with references for the three letter acronym for a controlled substance,
nothing much has showed up, and the manufacturer was not very proud of
the board, so that won't reduce ambiguity in searching for info.
It has a z80, and a couple of Parallel I/O chips as well as a Zilog CTC
on it, so it is smelling like some sort of equipment interface or
perhaps a Laser printer or high speed printer board.
Probably has a 2716 chip on it for code, would like to get it imaged and
disassembled.
http://jimsoldtoys.blogspot.com/2016/02/pcp11e-qbus-board.html
I did a quick look at the thing and there are pictures of the overall
board as well as closeups. I guess one could hope to play with CPM on
it if nothing else.
thanks

BAD is destructive to the data on the disk!
If there are only four tasks that have read issues you may be able to move just those
tasks over from a good version of RSX-11M with Kermit which you mentioned you had.

A RD51 drive holds about 10 MB which is about the minimum for a RSX-11M system. The RX50
disks could load a version of Micro RSX which was a pre-GENed RSX-11M system. I used it
one time to recover a non-bootable RSX system disk where someone deleted the RSX11M.SYS
file that the boot block pointed to. I have not seem those RX50 images of Micro RSX on the internet so far.
Since you can read and write the RX50 disks with a PC. Get a copy of PUTR from John Wilson Dbit site
http://www.dbit.com/pub/putr/
to be able to write RX50s in RT-11 which can be read in RSX-11M with FLX. Then get a copy of Simh
>from the GitHub:
https://github.com/simh/simh
Once you have a working Simh PDP-11 emulator (e.g. pdp11.exe) then get a bootable baseline RSX11M disk image
ftp://ftp.trailing-edge.com/pub/rsx_dists/rsxm70.dsk.bz2 (Note: this disk image is actually RSX11M V4.8
The Simh will need a configuration file (e.g. sim.ini) that describes the PDP-11 system it is emulating like this:
sim> do sim.ini
set console log=./console.log
set cpu 11/23, 256K
set cpu idle
set tto 8b
set rq0 rd54
attach rq0 rsxm70.dsk
sim>show rq
sim> show rq
RQ address=17772150-17772153, no vector, RQDX3, 4 units
RQ0 159MB, not attached, write enabled
RD54, autosize, SIMH format
RQ1 159MB, not attached, write enabled
RD54, autosize, SIMH format
RQ2 159MB, not attached, write enabled
RD54, autosize, SIMH format
RQ3 800KB, not attached, write enabled
RX50, autosize, SIMH format
sim> b rq0
and it will boot RSX11M where
this will bring up a baseline RSX11M system. DU3 should be a virtual RX50 that will create a disk image that can be read with
PUTR and moved to a real RX50 or you could use Linux DD to image the RX50.
At any rate the emulated RSX11M system will have the tasks that should be compatible on your real PDP-11. You might also
be able to kermit from the simulated to the physical PDP-11.
At any rate having a virtual RSX11M system to experiment with will help you a great deal in getting your real system running.
If this is too complicated, I could try sending you an RX50 disk image with the tasks you need, but I only have RSX11M V4.8
(I mostly use RSX11M+ V4.6) handy so we'd have to try those .TSKs to see if they might work.

If you are not getting errors on the disk, then the disk is probably ok and the file
system has some corruption. Remember that an RSX11M system should be
shut down by running shut up to make sure all files are closed etc.
>RUN SHUTUP
BRU can do disk to disk copies but with only one RD51 and no tape it won't help much.
In my RSX work I use a SCSI disk controller like a Emulex UC07 with the SCSI2SD
card that emulates unto 4 DU disks on one microSD card. This makes it very easy to move
large disk images from Simh on a PC to be bootable RSX disks on the PDP-11. It is
easy to back up and very reliable. The SCSI2SD card is only $65 but Qbus SCSI cards
are a bit pricey.
By the way which CPU is in the PDP-11, a 11/23?
Good Luck,
Mark

Good work on getting the 2116A working again.
Anyone care to speculate on the initial low sales of the 2116A? was it
because HP weren't well known for producing computers at the time or
was the $22K asking price too high compared with say DEC's less than
$10K for a PDP-8?
I recapped a Mac SE/30 a few months back and only just now put it back
together. After a false start with dirty contacts on the ROM simm and
resulting irregular vertical bars, the machine is working again. There
are no more zipping sounds coming out of the speaker. Two problems
remain:
1) There is slight pincushioning along the bottom of the CRT, about a
third of the way in from the left.
2) The CRT produces a rather noticable and irritating flicker. I don't
remember the one-piece Macs flickering like this.
I think a cleverly-placed magnet might fix the pincushioning and recapping
the analogue board would remedy the flicker. Can I get some thoughts,
commentary, and suggestions on this?

Q: Why is top-posting such a bad thing?
A: Top-posting.
Q: What is the most annoying thing in e-mail?
If my house were on fire and I had to pick what to save, near the top of
my list would be my MicroVAX in a BA123 enclosure. It is by FAR my
favorite computer. Sadly, there was a tragic accident and the
ventilation louver, just about the power switch got broken. I know, I
know. How could this happen? I am overcome by guilt. I can't rest until
my poor, sad VAX is fully repaired and back to it's perfect condition.
I've tried to repair it, but not had satisfactory results. Is there
anyone out there that would be willing to sell me a replacement?
Not an essential manual but for completeness I would like to find a
copy. If anyone has one would they be willing to scan it please or I
can arrange to get it done.
The list of manuals for the DECwriter I LA-30 are:
(missing) EK-OLA30-OPLA30 DECwriter User's Manual
(online) DEC-00-LA30-DC1972-08LA30 DECwriter Maintenance Manual
(online) LA30 Engineering drawings Nov-1973
(online) via Manx or bitsavers.
If anyone has paper for these printers in the right size I'd be glad
to have some (whatever would fit in an large envelope). LA30 is fixed
sprocket position, needs 9-7/8 inch wide (1/2 inch pitch x 0.150 inch
diameter feed holes) continuous paper.
The M24 I got the other day has the bus converter, whereas the other M24
that I already had does not. I bought a bus converter for the "old" one, but
then realised I didn't have any mounting bushes or spacers in order to
install it. I thought of removing some of the bushes from the new one to
share with the old one, it wouldn't be as good but at least I would be able
to install the converter.
It looks like I might need some kind of special tool to remove the bushes
>from the new machine. Is there a way to do this with ordinary tools? Does
anyone know if the mounting bushes are any kind of standard part that could
still be bought somewhere?
Thanks

Hi,
I'm putting the finishing touches on my efforts to re-draw the M865
schematic for the website www.so-much-stuff.com (which has a
collection of similar drawings). I am looking for photos of the
front and back, reasonably square-on, with enough resolution
and light to make out the traces easily. My intent is to "trace
over the traces" with my CAD software (Eagle 6.6), to document
the board while simultaneously verifying the work I've done to
draw the schematic.
Does anyone have photos of the component and solder sides
of an M865? It's the older Omnibus serial card, with the current
loop cable soldered in.
Permission to use the photos on the website would also be
great.
The folks I've found so far who own boards can't get photos of them
for a week or more, and I'd like to finish these drawings before my
motivation fades. (I know from experience how long it can take me
to get back to half-finished projects!)

Ok, if you don't have [3,54] then you must have RSX-11M not RSX-11M+. In that case you
should have two versions of Indirect:
[1,54]ICP.TSK
[1,54]ICX.TSK
ICP.TSK is the default, "full capacity" version and in V4.0 of RSX11M it shows up under TAS as:
>TAS ...AT.
...AT. 1.0 GEN 64. 00060000 LB0:-00114253
so try removing it as you did above and then INS the ICX.TSK and try it.
>REM ?AT.
>INS [1,54]ICX.TSK
>TAS ?AT.
...AT. 9.01 GEN 64. 00060000 LB0:-00114033
It would be good to know which version of RSX-11M you have and also a bit about the configuration.
You mention backing up your data, what disks do you have? To back up a system disk sometimes
it is best to use BRUSYS.SYS which on M should be in [1,51] It is a memory resident version
of BRU (running under RSX11S) that you BOOT and then can copy disks.
Good Luck!

I recently picked up one of these devices. I'll apologize in advance if
you folks have already had a discussion about the MiST. Basically, it's an
FPGA that's capable of emulation (for lack of a better term) of many
platforms on a hardware level. I only got mine about two weeks ago, and
I'm still sifting through a ton of material and focused mainly on the
Amiga and ST platforms (stuff I played with as a pre-teen and teen). I
have to say, so far it's pretty awesome.
The coolest feature in my opinion is the standard joystick ports on the
side that "just work" with all the emulation targets. I always favored
using Sega Genesis controllers in those (rather than the rinky-dink little
"red joystick" of the time). They work oh-so-great with this rig.
The only issue is finding a monitor that doesn't have a fit over 15Khz
refresh rates. I use an NEC MultiSync with sync-on-green and all that fun
stuff. I'm still busy getting AROS running on "my Amiga" (which is
represented by an SD card with my ROM image from my A3000 and a metric
crapton of floppy images).
You basically hit a keystroke or joystick combo and you can swap floppies,
reboot, etc.. If you are into any of these, I can recommend the MiST:
* ST/STE (also on SCART 15KHz)
* Amiga 500/600/1200 ( AGA CORE BETA core)
* C64 (partially - still developed)
* Atari 8bit ( 96%)
* Collecovision
* ZX81
* Atari 2600
* ZX Spectrum with AY, aslo with DIVMMC and ESXDOS
* SEGA GENESIS
* Apple II(x)
* MSX
* AMSTRAD CPC (BETA)
* A few others, you'll want to check.
BTW, I'm new to the list (1st post). So, I'll introduce myself. I'm
just another IT worker with a background in Unix systems. I'm 41 and I
started with HP-UX 10.x (high school) and branched out to every kind of
Unix box I could get my hands on (Yes. I'm one of those Unix zealots, but
that might be too gentle a description). I spent the 90's with SGIs (which
I still collect, I have an O2+, two Indys, and a bruzin' Tezro fully built
out). I spent the early 2k's coding for supper as a "security engineer"
(read: writing exploits which I don't much care for now) and some stints
as a Tru64 admin. On the in between gigs and contracts I've touched just
about everything (and in the last 10 years a lot of new Unix hardware).
I've professionally admin'd or coded for IRIX, Solaris, Linux, Tru64
(OSF/1 or Digital Unix for some), FreeBSD, HP-UX, UNICOS, and AIX. As a
hobbyist, I've also tinkered greatly with NetBSD (maybe my favorite),
OpenBSD, and Minix. Then of course there is the spacey or rare stuff I've
put hands on. I'm talking about things like UnixWare, Xenix, SCO, SunOS,
BSDi, DG/UX, NeXTStep/OpenStep, A/UX, and even non-Unix stuff like Sprite,
L4, QNX, HURD, BeOS, Haiku, AROS, Genode, and others. I code fairly well
in C, shell script, and TCL. I code not-as-well in AREXX, Python, Ruby,
PHP, Lua, and a few other scripting languages. I'm pleased to be on this
list, and to make your myriad acquaintances.

The ?AT. indirect command task will be found in LB:[3,54] and there are three versions of it (ICM.TSK, ICMFSL.TSK, and ICMRES.TSK) if this is a RSX11M+ system. This is the task image that is failing to load is probably ICMFSK.TSK. There is a text file in LB:[1,54]SYSVMR.CMD you can type to your screen:
PIP TI:=LB:[1,54]SYSVMR.CMD
a line in the file is:
INS [3,54]ICMFSL/INC=10000 ! Indirect command file processor
just above that line should be:
INS [1,1]FCSRES/PAR=GEN/RON=YES ! FCS resident/supervisor-mode library
if this is the case then then the ICMFSK.TSK is the one that is failing to load. So after the system boots and the ?AT.
fails, you can:
>REM ?AT.
>INS LB:[3,54]ICM.TSK
>@LB:[1,2]STARTUP.CMD
which should bring the system up. It is likely that you could also use ICMRES.TSK which also uses the FCSRES library. To see if the library is loaded the command is CBD. If you see FCSRES displayed then ICMRES.TSK should also work.
Once the system completes STARTUP.CMD, then you should make a change in the system image [1,54]RSX11M.SYS to use
the ICM.TSK at the next boot up. To do this you need to use VMR which makes changes in the system image similar to the MCR commands
on a running system.
>SET /UIC=[1,54]
>SET /DEF=[1,54]
>INS $VMR
>VMR
Enter filename: RSX11M.SYS
VMR>REM ?AT.
VMR>INS [3,54]ICM.TSK
VMR>^Z (Enter a control Z)
This sequence should cause the next boot to come up and chain to [1,2]STARTUP.CMD cleanly. Then you can rebuild INDFSL with the SYSGEN procedure as described by the previous post.

Also may be on the lookout for a colour frame buffer; mine may be
terminally flaky. Anything that works with a 4/110 - VME or P4 bus.
Thanks

Awhile back a "pre-alpha" version of the PC classic "DOOM" was unearthed
(dated Feb 28, 1993), and it claims to support a "high color" VGA mode.
>From the README.TXT:
"Use High-color DAC (160 x200, but great color!)
(Only newer VGA cards have this-if it looks OK, ya got it)
(This may--okay, will--REALLY screw up the playscreen's
graphics. Just look at the neat colors and don't worry.)"
I've tried it on a number of machines (from the 386 era to a modern PC)
and they all just end up showing garbage when this mode is enabled. I
cannot for the life of me find a reference to this mode existing
anywhere, but I assume it must have worked on *some* SVGA chipset of the
era since ID programmed in support for it. I'm guessing it was cut
because nothing else supported it (and because 160x200 must have looked
awful, even with lots of colors...)
Does this odd video mode ring any bells with anyone out there? Any idea
what hardware to look for that might support it? At this point I'm more
curious about the actual hardware than getting this pre-alpha to run
with it...

Actually, in most jurisdictions, it's death+N years. In the US, thanks to the

So here's an 11/23+ in a nice BA11 box:
http://www.ebay.com/itm/322046582015
If I wasn't _already_ knee deep in the blasted things, I'd buy it myself! ;-)
The other cards aren't too interesting - an MXV11-A, MRV11-C (I think), a 64KB
memory card, and what looks like an off-brand DLV11-J; and some sort of disk.
Still, not a bad price (so far) for the CPU, box, and a handfull of boards.

Well...
REM ...AT. worked since an AT entry was present in the TAL output

Disk (RD51) has 850 blocks free after some cleaning up. It had 738 before.
I confess it is in no way a classic machine, but I thought that this
might be of interest to some people here. I had not heard of it before
until a chance retweet from a ZX Spectrum-related account today:
http://rc2014.co.uk/
?
RC2014 is a simple 8 bit Z80 based modular computer. It is inspired
by the home built computers of the late 70s and computer revolution of
the early 80s. It is not a clone of anything specific, but there are
ideas of the ZX81, UK101, S100 and Apple I in here. Built mainly with
parts donated to Nottingham Hackspace and components salvaged from
random bits of equipment, it uses modern PCBs.
It runs on a backplane that hosts the individual modules. This has
standard 0.1? header sockets meaning new modules are simple and cheap
to design and can use Veroboard or even jumper wires to breadboard.
For resilience, most of the modules have been designed on to dedicated
PCBs.
In it?s typical basic form it has;
32k RAM,
8k ROM (running Microsoft BASIC),
3.7628Mhz Z80 processor
serial communication at 115200 baud.
Other modules include 8k x 8 bank switchable EPROM, SD card
bootloader, ZX Printer interface, Blinkenlights, LED dot matrix
display driver, LCD display driver

Apologies all for the OT; just a few _brief_ replies. If anyone wants a

> From: Charles Anthony
> What they did was 'NAT plus IPV6 will solve everything.'
Yes, but not explicitly; the 'official' IETF position was 'IPv6 will replace
IPv4', and they pretty consistently refused to acknowledge that NAT would
likely play a major role.
I 'sort of' understand the second part - NAT is, architecturaly, very grubby
(for a long list of reasons this is not the place to go into) - but it soon
got the point of ostrich-like refusal to recognize reality - which meant that
instead of an _architected_ approac to using NAT, it mostly got an utterly
'ad hoc' adoption.
> From: Robert Johnson
> So, I'm curious what your objections to v6 are
It's different from IPv4 (i.e. old code can't understand it), but not
different enough (i.e. it doesn't have enough new capabilities to make it
worth switching to - IPv4 has many architectural issues, but that topic is
too complex to go into here).
> how would you solve the shortage of IP addresses?
You have to start by realizing that IPv4 addresses serve at least three
functions: i) identify the communicating device (in the sense that 'Noel
Chiappa' identifies me), ii) says _where_ the thing is in the Internet (like
a street address does IRL), and iii) is used by intermediate switching nodes
to forward traffic. So the first step is to pull out ii) and iii), which can
be done without modifying the hosts, and there are many designs that did so.
Alas, a fuller discussion of this complex topic is not really appropriate
here... Ask on internet-history, if you want to know more.

OK, I'm mostly done with the disassembly; available here:
http://ana-3.lcs.mit.edu/~jnc/tech/pdp11/M873-YA.mac
I haven't fully understood the TA11 code (and don't plan to), nor the
DECtape/magtape code (might get to that some day), but the disk and paper
tape code is completely done. (I'm currently loading over serial lines, for
getting the machines running, etc.) The paper tape code is 'interesting'; it
took me a while to figure out _exactly_ how it worked.
It appears (to me, at least) that that code will not function correctly
unless the abs-loader has at least one byte of '0' pad on the end of it, for
two reasons. (See the comments on the listing.) Luckily, my copy of the abs
loader binary has such; although real .LDA tapes have blank leader, of
course, the .LDA files I'm generating don't.
The serial line code in the M9301 (-YA at least, and probably the others too)
uses the identical code, so it has the identical issue.

Hi!
Got a MicroPDP 11 plus.
It seems to be misconfigured.
It can't execute .CMD files, reporting
Task "...AT." terminated
Load failure. Read error
No disk errors are reported with ELI DU0:/SH
Disk seems to work: I can run .TSK files.
The file STARTUP.CMD isn't read at all.
Any hints? Which file is executed right before STARTUP.CMD?
I see two RED commands and a MOU before it tries to read [1,2]STARTUP.CMD and reports the aforementioned error.
Thanks
I just finished laying out the board for the MEM11A. The last roadblock was figuring out
where the last 3 unrouted wires were. EagleCAD didn?t make it easy to find them and I
haven?t quite figured out how to use the autorouter on Eagle 7.5, so I did this all by ?hand?
(at just under 2000 wires it took a while).
I haven?t re-set the grid from all of the other boards (all thru hole parts) that I?ve done,
so this board is probably not optimal (plus I was getting the hang of doing a 4 layer board).
I ran into a lot of wiring congestion that caused me to reroute the entire board as I moved
parts around. Even with a finer grid pitch it?s unlikely that the UMF11 will fit on a single
SPC board.
I?m going to check the board over for the next week or so before I send it out and about
4 weeks after that I?ll have the first boards that I can populate and try out!

Another old thing I've been interested in selling, is my SEIKO
RC-1000 Wrist Terminal.
This watch has a two line 12 character display, where you could also
load text and alarm/reminder data.
I used it for phone lists and meeting reminders. It comes with a
DB25 cable that connects to the watch to download data.
Example on eBay:
http://www.ebay.com/itm/RETRO-1980-s-SEIKO-WRIST-TERMINAL-S501-4000-RC-1000…
I'd been trying to figure out where I misplaced the 5.25" floppy with
the software, until this last weekend, I found it in a stack of old
Infocom game floppies.
Unfortunately, when I stick it in my one remaining working 5.25"
floppy drive, it made a little noise and decided it couldn't detect
formatting. Looking at the diskette, there seems to be some marks on
the oxide. Possibly a head load problem.
It's also possible that it's just an old format this system doesn't recognize.
Anyone in the area (north of Boston) have a working old PC?
This is labeled as an IBM/MS-DOS version. I used it once many years ago.
Does anyone have this software archived or available?

Guys,
still trying to clean out my basement... recently I've gathered
a bunch of PC cards from over the years.
and some of my old text and data books. Still working on listing
some more and some various kits of PC software.
I'm not assuming this is worth much, just rather pass it on, than dispose.
I've put a list (so far) of the stuff on this web page. I have
photos of the PC cards if interested.

Urrr, hadn't thought of that! Sigh. I wonder if it'd been mentioned here
before, and I'd missed it because it was before I joined? Luckily, having
that cable in backwards doesn't harm anything...
Well, hopefully this:
http://gunkies.org/wiki/KY11-LB_Programmer's_Console
will save at least some other people...
Noel
So, something I just found out the hard way, while debugging another
'situation' with a PDP-11/04:
The KY11-LB Programmer's Console maintainence manual contains a major error,
in describing the configuration of the 20-conductor flat cable that connectors
the front panel and the UNIBUS interface module (M7859). This is covered in
Chapter 9, "Installation", which includes two figures, Figures 9-4 and 9-5.
Those figures show the 20-conductor flat cable with the red edge stripe
toward the outer edge of the front panel PCB (correct), and also toward the
outer edge of the M7859 (WRONG). On the M7859, the red stripe edge needs to
be oriented _away_ from the outer edge of the board.
If it is plugged in as shown in these figures, the machine will not operate:
the four 'RUN/SR DISP/BUS ERR/MAINT' lights will be on, but nothing else, and
it will not respond to any keys. Fortunately, plugging the cable in reversed
does not damage anything; simply reverse the cable.

I had a PCB made of basically the same circuit, with a TLC7705 voltage
supervisor/reset circuit added, and a stuff option for an actual
RS-232 port. I've added photos to the album linked above. Unlike the
solderless breadboard version, it did not work the first time, and I
haven't yet figured out what's wrong with it. The reset circuit seems
to work correctly.
I should have added a bus connector for I/O expansion. I was in a
hurry and it had to be under 100mm square to get the boards made
inexpensively.
Rather than soldering in the exceedingly rare 3M QUIP socket, I
soldered down four 16-position single in line machined-pin sockets,
and plugged the QUIP socket into those.

I was _extremely_ amused to hear that.
(Backstory: I'm a long-time detractor of IPv6 - I've always thought it's a
rolling ball of digestive byproduct, to be blunt. In fact, if I had still
been on the IESG when it came around, I'd have canned it. Unfortunately, I'd
resigned a while before [for unrelated reasons], something that in hindsight
I've greatly regretted, since it removed my ability to can IPv6. So to hear
that IPv6 is _still_, all these years later, not that crucial to useful
functionality, is very satisfactory to me - it says my assessment was right
on the nose. Long may IPv6 fail to be successful! The single biggest/most
expensive IT failure of all time?)

So, I?m curious what your objections to v6 are (I know there are some very good technical objections, because v6 is unlike v4 enough to be a breaking change from a programatic point of view) - or rather, how would you solve the shortage of IP addresses?
