Anyone know if mcm electronics changes the shipping charge before you pay or are they all flat rate/minimum of 9.49 to ship? Between them charging extra for shipping and adafruit charging extra for the device but admitting shipping is only $4 it sorta comes out the same. I just don't know who I'd offer the mark up (if I have to pay one) to.
Various "time-nuts" start off with GPS disciplined rubidium clocks, or radio clocks like WWVB, and derive a phase-locked 60Hz to run the old-fashioned 120VAC continuous-hand-movement analog and flip clocks (in my circle known as "NUMECHRON"s although I think the most applicable trademark was TYMETER).
One example is: http://leapsecond.com/pages/atomic-nixie/
Obviously an HP 3325B is overkill as a 60Hz synthesizer but you get the idea. If you have WWVB carrier, 60Hz is just dividing by 1000, no funny numerator/denominator stuff.

Wow...what a great machine. I spent some time with Smalltalk on one in the
before-times. Really advanced, well made little box for the time (and
expensive).

I'm afraid I don't know what the last UTek was for that box, but 3.1 is a
reasonable guess. UTek did come on QIC tapes (which is what we used); I
never loaded it from floppies or saw a floppy distro. That said, most of
my UTek stick time was on later versions and later hardware (XD88
workstations). I can't imagine where one would find the install media
these days other than lucking onto someone with a similar machine.
I vaguely recall that all 4xxx machines could be loaded from the same
distro media, but I can't confirm that. That said, if you do find someone
with a working system, you could clone the drives. They're SCSI, and 'dd'
just fine.

Not sure exactly what you mean by "connections", but I'm pretty sure the
one we had had ethernet, serial, PIO, and SCSI. And the video output of
course.
Good luck with it. I'd love to have one running Smalltalk and/or Lisp.

RE:PANASONIC HHC RL-H1800 TV DISPLAY ADAPTOR
Thankx all for the info and help with my HHC questions.
i did win the ge programmer with working HHC on ebay for around 50 dollars.
so now i have an hhc with working display and some GE spares.
Tony my answers to your post is below:
>Waht exactly is the fault with the existing one? Missing columns? Missing

Missing row's on the last third of the display almost to the end of te display.

there were a few hhc peripheral's besides the tv adaptor and printer.
according to my manual that came with the hhc used in the ge programmer there was: the I/O adaptor for six peripheral's, two printer's with cassette i/o on them , an acoustic coupler modem and a ram module.
Ge used two modules with the hhc/printer/io adaptor setup: one module held eproms for software that programed the ge two way radios and the other module interfaced the radio's to the hcc via cable or ZIF sockets for bare eeproms.
google "ge suitcase programmer" for info on the GE/HHC setup.
there was one other HHC set up that used only an HHC and printer for insurance companies - the printer attached directly to the HHC and the custom insurance software was on a "capsule" (rom chip) that went in the back of the HHC.

Hi all,
The orange binders are spoken for. But the large paperback books are still available.
Rob Jarratt has expressed his interest for the VMS 4 documentation, but as said, that's gone.
Anyone interested or can I bin it?

I think my main problem with it is that I'm tainted by nostalgia, and what
I really wish it was is a backplane system with separate cards for ROM,
RAM, CPU, I/O, video etc. :-) Much more fun to mess around with, put into

Hi Dave
Yes, those links were the three mentions that I had previously found (plus links to some ads in archived magazines).
However, since the interface board is a S-100 bus card labeled as "Strobe 100 parallel interface" I believe the RS232 is a different option that this does not have, or the link from the plotter enclosure to the card itself is using RS232.
The Burroughs document defines their graphics subroutine library and mentions that these can be used (unsupported) on the Strobe plotter, but not enough to write anything that will talk to the box. Further, they mention in appx B the configuration file that defines the format for talking to each peripheral that there is a format Strobe which is different from the HP plotter formats. The review link mentions commands, which do not sound like HPGL to me, but with only these three documents to go on, it is a grain of data and a pound of interpolation to decide what the protocol might look like.
The DR Graph document mentions a unique driver for the plotter, in a long list of many different monitors, plotters and printers. All of these documents suggest to me there is a unique programmatic interface, thus I was hoping for a one in a million chance that someone has the manual or enough documented about this plotter to allow me to send it valid sequences. All mention RS232 so that may at least resolve the question of communications protocol - well documented across the three links you listed. What to send over that link is the question now. Reverse engineering may be quite challenging, but I might be able to replace the controller inside the plotter with my own controller, driving the servos and motor myself, thus free to create my own programming interface.
Thank you for looking and posting the citations.
Carl

Pierre's collection of classic computers : http://classic-computing.dyndns.org/
The 20 wire cable that might have been an RS232 link is definitely not - among other signs, pin 3 is ground, not receive data.
The S-100 interface card has no UART or intelligence, just routes the signal lines through an 8255A to the bus.
Finally, opened the plotter itself - no microcontroller/processor, no logic circuits, just transistor drivers to activate the stepper motors and solenoids, wired to the various lines of the cable.
So, yes, it is a parallel interface and it appears to be completely proprietary to the Strobe plotter. No fancy protocol to speak to it, at least, just raise lines to drive the motors one way or the other in 3.6 degree rotary steps. The power supply in the plotter has a 7805 on it, so appears to be standard TTL 5V interface at first glance.
Seems it will be more straightforward than I thought to put this into service.

Hi, all retrocomputing fans!
I'm starting a new podcast called Floppy Days to discuss vintage computers and calculators. I plan to cover things like:
- history
- specs
- emulation
- modern upgrades
- magazines/books
- assembly language tools
and much, much more.
I plan to cover the vintage computers and vintage programmable calculators in which I have interest, or in my collection, and would be willing to cover computers I've never seen or were not popular or available in the U.S. I would love to be able to interview experts on these systems as well, if anyone would be willing to participate.
I would also like to know if anyone would be interested in being a co-host for this show. It would make it much easier to pool our knowledge and share the workload.
The podcast is on iTunes, or you can download it at:
floppydays.libsyn.com
Thanks so much and please listen and provide feedback if you can.

The latter projects would be fun. I've been pondering getting one to
put as small a linux distro on as possible and then getting Brad
Parker's CADR emulator http://www.unlambda.com/cadr/ running on it.
That would make for a screaming little LISP machine :)
Getting SIMH & running 2.11BSD on it's emulated PDP-11 or VMS on the
emulated VAX could be entertaining as well.

A friend of mine asked me to repair his failed Commodore 64 many years ago.
He thoughtfully supplied a schematic for me to work from.
As far as I recall (and nobody ever accused me of having a good memory), I
wrote some code using the assembler on my BBC Micro, put it in an EPROM,
swapped that for the ROM in the Commodore and identified a RAM problem
by outputing status on the user port.
I'm not sure I should admit to this but rather than an EPROM, I think it was
actually my cheapo EPROM eliminator - a 2K static RAM equipped with two flying
to a bench power supply...
If I remember correctly, I replaced the suspect RAM chip and the machine
worked.

Peter Coghlan.
Been thinking about it recently also for one or two projects. Has anyone tried any of the other little usb stick microcomputers? I've seen various comments on some *really* cheap ones on amazon which seem pretty competitive other than no ethernet port but a lot of heat/overheating comments.
I'm tempted for the raspberry just for a dlna server with attached (but self powered) usb drive. Others could do similar various tasks though.
I have been testing my C64s today, and 1 works perfectly, joysticks and
game, etc.
Hooked up via DIN cable to 3 RCA to Commodore color monitor, everything is
fine.
My questions are these:
1 of the C64 powers on, but absolutely nothing appears on the screen.
1 of the C64 has a totally different pin configuration for the monitor and
disk drive, only 5 pins for the monitor. The FCC ID, model number, etc. is
exactly the same as the others, but these connections are different. Any
ideas?

http://i.imgur.com/VtMxSqj.jpg
is it another peripheral chip or perhaps a CPU? I'm guessing the
former since I don't see anything that might hold ROM code for a CPU.
The Intel 4178628 to the right is an Intel 8255A-5 (Programmable

The seller did not pack the terminal properly at all, and the fragile

I believe someone on the Vintage Computer Forum has a Mindless Terminal that
he doesn't know what to do with (he thought it was a 'normal' RS-232

Failing that, you can use an ordinary RS-232 terminal, although you may have
to burn a new monitor ROM.
FYI, if you decide to keep it, there is a Vector Graphic user group and
quite a bit of documentation and software available.

OK, so I hacked a quick 'n dirty xmodem implementation together in RSI
BASIC on the QX10 so that I could transfer a few essentials over via the
serial link.
It worked on a few files, but I've found a couple of problem files where it
will consistently block when trying to send an ACK back to the sender
following a packet receive - in one file it's on packet 76 every single
time, while in the other it's always packet 161 (it receives the complete
packet OK, checksum is valid, packet sequence numbers are all good, but it
stalls writing to the serial port).
Any thoughts? I can't think of a reason why it should work fine on some
files, but barf consistently - and at different points - with these other
two. I did wonder if there was a particular byte encountered in these
packets which hadn't been seen previously in these files (or any of the
others I've sent successfully) which was somehow tripping up the underlying
serial code on the QX-10, but that's not the case. I suppose there might be
a particular magic *sequence* of bytes which is received and causing
problems, but that's harder[1] to check for.
Oh, I've disabled the disk-write code on the QX-10 just to rule that out,
too; it still fails even when it's just tossing received data away.
[1] hmm, although I could just zero out the problem packets and see if that
stops it happening, I suppose. Will report back.
cheers

Recommended version is 2.0 Model B (that happens to have 512MB; the
1.0 "B" has 256MB but those shouldn't be in the dealer channels
anymore). Everything shipping as new for months now is a 2.0 Model B
(the "A" is only starting to ship in Europe, so doesn't come into play
with US orders). Primary distributors (MCM Electronics or
element14/Newark) charge $35 + S&H for it (and sales tax if you are in
their state). Secondary distributors (Adafruit, etc) often charge $40
plus S&H and tax.

Sellers on eBay are marking things up a bit because demand is still
higher than supply.

Maybe they're the next big thing I don't know. You'd sure get that impression looking at the eBay listings. I payed 5$ for my largish IBM 7374?. No carousel though. I've never actually run it, but it powers up and all, though reports an error after a bit ***Need docs***. I plan on machining/fabricating a carousel. You really don't need one someone pointed out, for circuit board work, or really anything, so long as you're willing to manually change pens.
Longshot...is it possible that the 8255A is really an 8355A (same w/ mask
programmed ROM)? That could make the unknown chip an 8085A (among many
other things).

I looked into buying a Acorn Archimedes/RISCPC system the cost kill that idea
to get my riscOS fix I decided to get a RaspberryPi and buy the??RISC OS Pi SD card from RISC OS Open[1]

Hi
Quick update on the S2I SASI/SCSI-1 to IDE/SD bridge board.? A great deal of progress recently.? Still making adjustments to the next generation S2I prototype board.? Will be converting from EEPROM to Flash to enable 20 MHz operation.? Still looking for additional testing for compatibility.? Will post when available.
?
Thanks and have a nice day!

Date: Sunday, February 24, 2013, 10:49 PM
I have posted an updated firmware archive on the Wiki. ?This update includes:
Debug and non-debug variations. ?Non-debug goes much faster, but does not dump any diagnostics on serial port.
Support for FORMAT UNIT and VERIFY commands.
Improved performance in PPI IDE interface driver.
Support for multiple LUNs
I am generally finding that the non-debug version is running about the same speed as a real ST125N hard disk when using a 12MHz CPU clock on the SCSI2IDE. ?Given a fast enough ROM chip, 20MHz operation works and achieves much better performance than a real ST125N.
If anyone is getting close to testing, let us know!
Thanks,
Wayne

Hi
I was recently given a Strobe 100 plotter, with an S-100 bus interface card, but no information at all about the protocols or commands or other details needed to connect with and use it. I have searched the usual places and cannot find any manuals or details. Does anyone have a manual for the 100 (or the similar models 200 or 260), or even remember enough to help me get this working. My requirements for it are very simple, pen R, L, F and B, plus pen up and pen down are all I need to command it to do, always in single unit steps. I am going to interface this to my 1130 replica as a replacement 1627 plotter (small Calcomp device rebadged by IBM for 1620 and 1130 computers). The 1130 only needed those few commands I listed above from its plotter.

I recently bought a Vector Graphic MZB-5025 and its matching display and keyboard from a seller on eBay:
http://www.ebay.com/itm/Vector-Graphics-MZB-5025-Computer-Z-80-CPU-64K-RAM-…http://www.ebay.com/itm/Vector-Graphics-MT-Terminal-Mindless-Terminal-and-K…
The keyboard and display are packaged like a terminal, with styling
nearly identical to the SOROC IQ-120, but the video generation is
actually performed on an S-100 card in the main chassis.
The seller did not pack the terminal properly at all, and the fragile
structural foam enclosure was shattered in transit:
http://www.flickr.com/photos/20002766 at N03/sets/72157632849299607/
I thought I was buying a nicely packaged and complete S-100 system
that would need only electronic repairs at most, but instead ended
up this mess. I imagine that the case could be restored with some
fiberglass cloth, resin, and body filler, but I'm not up for it
myself.
If anyone on the list as a particular affinity for Vector Graphic
gear and would undertake such a restoration, please let me know.
I could probably be talked into turning loose of the entire system
for next to nothing.

Hi all,
I'm trying to ask here, since searching the russian internet and asking
russians not helped me at all.
I do have an craddle with something of an 11/03 clone and a RX01/02 double
disk drive. The computer is an Elektronika E60 and looks like this:
http://commons.wikimedia.org/wiki/File:E60M.JPG?uselang=ru
This is the CPU card (my own picture):
http://www.tiffe.de/Robotron/E60/E60-01.jpg
the pink chips at to are dynamix 4kx1 RAM like the Intel 2107
the CPU itself is on the right side, a RALU, the Control Unit and 3
Microcode ROMS. That all on a Quad size board, but altough it is a QBUS
nothing fits to a real DEC Machine since all Dimensions are metric,
including the connectors.
I have this beast running, with FODOS which is in fact RT11 and some
RT11v4.x andRT11V5. Variants.
Now comes my Problem:
http://www.tiffe.de/Robotron/E60/I17.jpg
This is a tape controller for drives like this:
http://www.tis.kz/cm53001.php (russian site) at this site there is an other
controller connected, a more modern one with an 8080 CPU and two 8255s on
it. As you can see the cable to the drive is directly soldered to the
board.
All kind of russian Sources are listing my Controller Board MC2702 or I17
(with a cyrillic letter 'i') as one of two possibilities to connect the
CM5300.01 drive to this computer, the other possibility is is an entire
craddle full of simple TTL chips that must be connected to the E60.
My I17 or MC2707 controller has four AM2901 compatible chips (K1804VS1)
and a AM2910 (K1804VU4), some microcode ROMS etc.
The two 40 pole connectors are electrically connected in parallel, maybe
to connect two drives. There is a similar controller to mine:
http://andy.sumy.ua/old_computers/world_museum/dvk/DVK_Type.jpg
with a single 50 pin connector for the drives and the same AM29x series
chips on it. For this controller the schematics are exiting..what doesn't
help me that much, since because that is a microprogrammed CPU all functions
of the interface, what is using different ICs, are depending on the
microprogramm. Ther are single 7474 Flipflops where D is connected to the
drive connector for example, I'll never find out what kind of input
this may be w/o some dokumentation. At least the ROMs are socketed but to
find out what happens I had to find out the complete schematic and then
dissassembling Microcode... :-|
The russians are listing that controller as standard, but no one knew
something about it, there is no documentation available anid no one in
russia seems to have such a beast. (two german friends of mine have two
other boards but waiting if I can come up knowing how to use them..)
The controller is listening on standard addresses on the bus (don't ask me
for now, it's a while since I've checked this) and it seems to react to a
reset command, seems to be alive...
Please guys, I' looking fo any documentation about this thing or at least
for the pinout of the cable to connect it to an CM5300.01 (bulgarian) 9
Track drive. (Should have 3 connectors at the other end so far as I know).
I've searching for over a year now, hope someone from one of the other
countries behind the iron curtain before is listening here and can help..
Please help!
Kind Regards,
Holm

All,
I recently found out that Edson Hendricks (the creator of VNET) wrote a copy of Spacewar!
for the IBM System 360 while he was an MIT student. It was based on the PDP-1 version,
and it was used by MIT for their annual open house in either 1965 or 1966. My understanding
is that this S/360 version ended up getting played by IBMers at the IBM Research Lab, which
resulted in a corporate ban of running the software on IBM machines. Considering that
the source should run on modern IBM mainframes with some code modification, I thought
that this might be something worth resurrecting for the 50th anniversary of the System
360 announcement. Do any of you ever recall playing this game on an IBM mainframe or
hearing about others that might have done this? Do any of you have suggests for finding
the source code for this S/360 version? Edson does not have a copy, and I have not
yet heard back the from Computer History Museum.
Thanks for your help!!!
Respectfully,
Sean P. McBride

I have a number of these. The possibility is they might get dumpsterized. FRU P/N 48G8723. Some still in the box, some still in sealed a.s. bags, a couple loose. Get them while they're hot, otherwise not.
I have 1 loose nos Commie. SX-64 crt left, currently on. ebay. If anyone wants it, or anything else, I'll pull it.

Don't know who posted what's above yours.
Other then that, are you an enthusiast, or just here for curiosity? There's roughly 2 camps here - those that collect and use very little, and those that actually use their old equipment regularly, and may even collect. It's an interesting unit, just wanted some discussion of it. Needless to say it's rarely seen on this side of the puddle.
Otherwise how do you feel about Google/Goozitzu these days?

ended up covered in glue at some point in its past. I'd like to restore

I watched both this and the A2+ vids Terry. Both well done. I just can't help but wonder how many marriages were put on the rocks by Apple though.

If anyone has a DEAD LK201 (with the membrane damaged or shorted
irrepairably) which has *RED* LEDs (which blink an error code due to the
shorted/damaged membrane when powered up), please let me know. I'm
hunting for one to get a working 23-004M2 masked 8051 microcontroller from.
(i.e. as seen in this random picture I found on GIS:
http://www.wickensonline.co.uk/retro/images/LK201-INTERNAL.JPG )
The LK201 with *GREEN* leds has a 23-001S9-00 MC68HC05 MCU in it
instead, and I am not interested in this one (as the extant scanned
lk201 schematic does not cover it and the PCB has a small custom ASIC in
addition to the MCU which seems irreplaceable).

Better pictures would help, including the back of the board.
