It has always been my understanding that the proper way to refer to
one of these is by the name "amphenol connector".

Exactly my point :-) And that's pretty much my reaction when I hear
people call things Centronics, that clearly aren't.

It's a small 5-port repeater, with one of the ports being AUI. It's meant
to extend an existing hub, but it can be used as stand-alone. It's
line-powered, too, I think. So you might need to have something plugged
into the AUI port (eg a computer with an AUI drop cable).

.ch is Switzerland, .cn is China. I don't know about .fm.
.ru is Russia. .ro is Romania
Just look up the ISO 3166 code list, or the list of ccTLDs (country code
top level domains):

I've no idea how on-topic it is, but... This last week I rescued a "Asante
NetExtender Hub" from the trash. In looking at it, it would appear to be a
combination Ethernet Transciever/4-Port 10BaseT Hub (yet it's smaller than
most 10BaseT Trascievers).
Is it what I think, or is it something different.

Linux does indeed have drivers for the 3c515, written by Don Becker (just
like almost every other network card driver in Linux). Web page for the
driver is at http://www.scyld.com/network/3c515.html. I have never used
them.

Hi
I have a mint condition CPT 9000 (J-Laser) Circa 1988. It is in original condition with Ventura operating in full screen mode. Any offers ?
Westward_Jersey(a)msn.com
OK... first of all, let me say that an XOR box weighs a ton. Second,
here's what I have - more cards than a single computer needs. I wish
I hadn't given away _all_ of my 68K S-100 stuff to a friend years ago
(but at least it's in good hands)
In the backplane when I got it:
o COMPU/TIME UFDC-1 floppy disk controller, c. 1983
Labelled jumpers for drives A-D, each with "5/8", "S0" and "S1"
1 34-pin connector
1 50-pin connector
WDC FD1795PL-02 FDC chip
no docs
o COEX 64K static RAM board, c. 1984
32 Hitachi M58725P 2Kx8 SRAM chips
no docs (but jumpers are labelled)
o COMPU/TIME SBC-880 CPU board (c) 1980
no CPU chip
Loose boards...
o QT Computer Systems RAM+65 SRAM board, c. 1981
32 2114 SRAMs (16K total)
missing IC49 (near the S-100 fingers, probably a 74LS240 or 74LS244)
labelled DIP switches
no docs
o Vector Graphic 8K SRAM board, c. 1980
64 2102 SRAMs
no docs
o Seals Electronics SRAM board, (c) 1976
64 2102 SRAMs (8K)
no docs
o SSM VB1C video card, c. 1980
docs
o SSM VB2 video card, c. 1979
chips still under plastic
docs
o Cromemco TU-ART Digital Interface, c. 1982
2 parallel
2 serial
NIB
docs
o Vector Graphic Bit Streamer serial card
8251 SIO chip
no docs
o MITS 88 UIO "Universal I/O Card"(?) c. 1977
M6850
AY-5-10134
26-pin Berg-styled connector
10-pin .154"(?)-spacing single-row connector (P-2)
no docs
o Unknown-brand mystery card (video?), c. 1979
8212
2 x 2708 EPROM (each marked 'FW II Gen', one with down arrow, one up)
4 x 2114-3 SRAMs
6-pin .1"-spacing single-row connector
U42 missing (24-pin .6" DIP)
no docs
o SSM CB1A CPU board, c. 1980
INS8080A
2 x 8212
2 x 2708 (marked "0-3V" and "4.7V")
2 x 2114
docs
o SSM 8080 Monitor V1 docs
command summary
listings
So, all in all, a good night's work. I'd love to learn more about
what I have, especially the stuff with no docs. Some of the docs
I do have, have schematics, but some of it is assembly and rudimentary
test/programming instructions.
I would appreciate any and all tips to online versions of docs for
this stuff. I would also appreciate any tips for getting an OS for
the box with its COMPU/TIME cards. I suppose one way would be to
receive a 5.25" image, reconstitute it and boot the system off of
mini-floppy, then format a disk or two on the 8" floppies and go
>from there.

For Sale or ???:
DIGITAL RAINBOW 100+ COMPUTER
This early 1980's machine is designed to boot DOS, CP/M and as a DEC Terminal.
CPU - Model PC100-B2, Serial #WFC3514 - with dual 5.25" floppy drive and
full height hard drive
Colour Monitor - Model VR241-A, Serial #Y31-008107 - with video cable
Keyboard - Model LK201AA, Serial #B033602238 - with cable [plugs into video
cable]
Printer - Model LA50-RA, Serial #TC73817A - with printer cable
Circuit boards in CPU are as follows:
5416206 5416205-01C1 [PC100-B MOTHER BD]
5415961 5015960-01C1 [PC100B MEMORY EXTENSION]
[27 sockets for DRAM; 9 populated with 50256-150 chips]
5415688 5015687-01J1 [No description on board]
5415482 5015481-C1P1 [PC100 RX50 CONTROLLER] [Floppy Drive]
5416019 5016018-A1 [PC100 RD51 CNTLR] [Hard Drive]
The hard drive is a Seagate ST-412.
No documentation.
No diskettes.
Includes 3 power cords.
In working order (except do not know how to test printer which seems to
POST OK).
CPU will boot from hard drive into CP/M but not DOS.
Plastic cases are quite suntanned (i.e. yellowed) except printer.
Pictures of the machine may be viewed at
http://members.shaw.ca/ajwotherspoon/rainbow/.
Located in Victoria, BC, Canada.
Shipping (including cartons), insurance and customs broker (if required)
are your choice and cost.
Using a bathroom scale the approximate weights are:
CPU - 32 lbs.
Monitor - 36 lbs.
Keyboard - 4 lbs.
Printer - 20 lbs.
Cables - 4 lbs.
Total - 96 lbs. (plus shipping cartons)
I have a box that could be used for the printer if packed in Styrofoam peanuts.
The hard drive should probably have its heads parked before shipping but I
will need instructions/software.
This is a collector's item, I am sure, but I have no idea as to its value
and I am not a collector. It was purchased new here in Victoria from
Computerland about 1983. I found it at a garage sale a few weeks ago. I
would hate to see it scrapped but I can't store it much longer! I will not
separate any components - it's all or nothing!
For my efforts I would like a few dollars in addition to the
shipping/insurance but not an outrageous sum. At www.omnicorp.net/dec.htm
(in New Jersey) I see the CPU is listed at US$85, the monitor at US$95, the
keyboard at US$50 and the printer at US$75 (all tested and guaranteed). I
am not looking at anywhere near these prices.
For further information or to make an offer please send email.
This machine was posted on December 19, 2001 in the comp.sys.dec.micro
Newsgroup and I have had one expression of interest so far.
