Hi, Joe
I just stumbled across the EV-831 thread while looking for a solution to
my Tape problem here at Nassau County School Board. We have a number of
old EV-831 boards wih old Sankyo 1/4 inch tape drives and are trying to
set up the boards/tapes in machines with CD burners so that we can xfer
all the old archive tapes to CD's for back-up/disaster recovery. Trouble
is we have no SW or drivers that work with the EV-831.
Could you send me Zips of the disks/programs that you mentioned in the
thread.
My email is [ mailto:john.pitts@nassau.k12.fl.us
]john.pitts(a)nassau.k12.fl.us. This would be a tremendous help. We've been
struggling with this for a couple of weeks and are at the point that we
were going to use the old (1993-94) Xenix machines that originally had the
EV-831's in them and kermit the extracted files over to a new machine with
burner HW/SW.
Anyway, TIA.

Hi,
Apologies if I missed an earlier post, but what has happened please to the
cctalk archive for 2001? There was a lot of great stuff in there, all nicely
searchable by Google.
Regards,
John
So, now that I discover I had a TU80, not TU81 controller in my 11/750,
I'm looking for a KLESI Unibus card, aka M8739. If anyone has one, I'd
be willing to offer some money or a trade of some sort.

It's possible to build one using standard parts. I'm nearly done with a schematic.
To complete it, I need to borrow a module for a very short time. Does anyone
have one they'd be willing to loan (or willing to ring out a few paths)?

I thought someone here might have an interest in these:

I certainly have to wonder about the history behind these cases...
Based on the description, the seller has more of them too.

I have 8 UTP (RJ45) to Fiber (ST connectors) Token ring media converters
I'm looking to either trade for 8 10Base-T to 10Base-FL (ST connectors) or
sell for what I've got in them. I bought them for $10.00/ea late last year
>from someone who claimed they were Ethernet media converters. I picked
them up for a local non-profit school, but all the gear I've set up there
is Ethernet, so they certainly won't work for the intended application ;)
These came without power supplies, but need 9VDC @ 1000ma to 1500ma. I
tested one on a 1000ma supply, but I know some media converters used to
use 1500ma supplies. I also have 8 9VDC 1000ma power supplies and the
correct input connectors available for these units, but if there isn't any
interest I'm going to see if I can get credit for them, as they cost me
almost as much as the media converters.
I put up a photo that I got from the original seller of these units here:

I've been in contact with someone who is looking to get rid of a large
collection of Sams Photofact folder sets in Akron Ohio. There are
approximately 1900 folder sets in 11 file cabinet drawers. If anyone is
interested, contact me off-list and I'll give you his email address. If
they were just a little closer, I'd certainly take them, but shipping from
Ohio would be expensive ;)

I found about 5 Lisa's doing the clean-out of the two local warehouses here
in Houston. All had some type of problem but one and it's running SCO Xenix
V3.0 as it's OS. I hope to get all five working again. Anyone know how to
read the mfg. date of 4304 ?
Hi
Beside the limeaway, also put the board in a bath of
vinegar ( white distilled ) and water ( 50-50 ) for about
20 minutes. The potassium hydroxide soaks into the fiberglass
boards and will pop out again. Vinegar is one of those
acids that forms a vapor and can get inside of things.
This is also good because it will eventually evaporate.
When mounting new NiCads, put them in a plastic bag and
run single strand insulated wires from the battery to the
board ( you noticed how it went right through multi-strand
wire ).
We have this same problem in pinball machines. Also
replace any sockets that might be suspect and any dip
switches that are near.
