Subject: [cctalk] Sun/Tronic House

Hi. I came across an article about the "Sun/Tronic House" in the July/August
1981 issue of Computers and Programming magazine.
The article references the Apple 2 as the computer that controls everything
in the house that also relies on solar energy.
The house, per the article, is (or was) in Greenwich, Connecticut. I also
found a photo of the house at
https://www.1000bit.it/storia/apple/suntronic_house.asp
I am curious to know if the house and the Apple IIs are still there. Anyone
has a clue?

(A copy of the magazine is at

1_4 page 38).

RL02 Disk and maybe pdp11 something at auction.

[Wayne Sudol via cctalk]

I spotted this for an auction from the  FORMER OYSTER CREEK NUCLEAR GENERATING 
STATION. 
Looks like a pair of RL02 with a pdp something in the middle. I can't make out 
what model it is from the photo.
Anyone know?

I'm not bidding as it's too far away from me in Los Angeles  but someone else 
might like it. Small stuff usually sells real cheap on this site as the sellers 
are usually  just trying to get rid of it.
Also, there's no current bid.  I just would not want it to go to a scrapper.

I found a spec sheet for the connector here.

Wayne, Ian, Marc,
   Thank you very much for pinning that one down for me so quickly. Yes they 
are fairly pricey, but at least that's a better price than Mouser.

I had a thought, that if the pin spacing was on par with say a common 15-pin 
VGA male connector I could buy a bunch of dirt cheap Golden Dragon ones, set 
them up in the mill and run a high speed slitting saw diagonally between the 
pins (right though the block and metal surround in one go), and just add a 
plastic spacer to bump it out to the length of the 19-pin. After all there are 
only 6 pins used, and of those, just one (assuming common) that would be on the 
extended bit.

Steve.

Here's a link to the vt52 maintenance manual. Has testing and service info. 
Hope it helps.

Well, let's see: I took the bottom off the VT52 and checked the connections to 
the high voltage board on the back. Cleaned up both connectors, plugged in, 
same problem.

I do hear a medium to high pitched squeal coming from the back board. 
Can't quite triangulate it (I need a hose and some time) but it might be coming 
from those center transistors. Any idea what these boards are doing, and if 
there is a schematic for these circuits?

Given that it went weird after being powered on for awhile I would suspect it 
has something to do with a component that generates heat. I could also take an 
IR picture of the back board and see if anything is unusually hot/not hot.

RE: Monroe 7860

[Wayne Sudol via cctalk]

As Monroe Systems is  still in business. Contact them, they might have an 
historian that could help you.
https://monroe-systems.com

Also, there a brochure for sale on ebait.  There is a preview of 4 pages that 
supplies some general  info (for free)

https://www.ebay.com/itm/VINTAGE-1983-MONROE-7860-DESKTOP-ACCOUNTING-CALCULATOR-BROCHURE-23-LB-32-CHAR/381996877124?hash=item58f0c9c544:g:NTAAAOSw32lYwl6G

In 1972, I programmed Burroughs L3000 accounting machines that could read 
magnetic ledger cards. I wonder if the Monroe could use the same kind.

I have a few reels of two-inch video tape which I've used to make crude 
magnetic cards for old HP desktop machines.

The ad actually says "IF WEIGHT IS OVER 150 POUNDS THERE WILL BE A CHARGE
FOR LIFTGATE OR RESIDENTIAL DELIVERY "
not that it does weigh that much.

Re: iMac ethernet connection quit - help?

[Wayne Sudol via cctalk]

Mark,  try opening a terminal window.  ifconfig -a will show you all
interfaces and their status. If en0: is down you can try ifconfig  en0: up
and see if it get an ethernet address. I.E. sudo ifconfig en0 up
If it comes up, trying pinging your router or any other addresses on your
local network as a verification.

The man page from a terminal window will help with the options to the
ifconfig command. I.E. man ifconfig

Here's an example from my mac.
fconfig -a
