Does anyone know if there is any programming information about the BDV11
card?
I have disassembled the ROM files for it and I see they do various
operations with the
registers on the card, but it is not clear to me exactly what they are
doing.

Hi all,
I'm trying to sell an old Scotch tape reel on Ebay Kleinanzeigen here in
germany. It's box is labeled 871-1-3600 R41 which I think means Type 871, 1
Inch and 3600 ft, Don't hve an idea about R41. Stock No: 84-9800-5294-2
I've bought that myself in a error..needed an Data tape to this time.
Now one asks if that is an vintage video tape for the philisp EL3400
Recorder..
Has someone an idea what kind of tape that may be?
Thx,
Holm

According to history Windows 1 was introduced to the world on Nov. 20,
1985, 40 years ago, minus 2 days. Prior to this Windows was first announced
in 1983(vaporware) but…An even earlier development was Interface Manager.
What we have now is much more and ‘better’ but for classic computing I
still prefer WIN 3.1.
Happy computing.

I found a Depraz mouse the other day (Type D 83 / P) while going through moving boxes. I used to - long time ago - make things out of broken or disassembled computer gear. There was the most amazing store in Dover, NJ called Second Byte where I spent too much time and money (according to my ex-wife). I purchased this mouse 30 years ago with no particular project in mind, and it has just stayed packed away.
I'm looking to sell it but I admittedly don't know what it's worth. I see two of them on eBay for $20-$30K, but don't see any Sold Items as a reference. Those sale prices sound largely aspirational.
The mouse is in pretty amazing physical condition, with only basic scuffing on the red surface. The larger spots you see are reflections. The cable has scuffs but no fraying at all. The ball turns when the mouse is rolled. No pins are bent on the connector (RS-232 / DB9?). The three buttons click.
Any insight - or offers - is welcomed.
Thanks.
Mike,
Where are you located? I am in the US in Georgia.
I have several of each of those connectors.

Does anyone out there have a spare 1/2 high 5 1/4" Seagate MFM hard
drive face plate (ST-221, ST-251, etc.) that they can let go cheap?
And also a 34 conductor dual drive cable and a single 20 on single drive
cable?
Thank you.

As we're emigrating soon, I am starting so find a new home for my collection of vintage computers and peripherals. On offer today is:

Please make an offer for either some or for all of the items (to martin(a)meiner.ch).
*) Items marked with a star were functioning well a few years ago when I was actively acquiring them. As times went by, it could be that one or the other may need TLC. I have not tested them again for full functionality.
Items are located near Zurich/Switzerland. It is the buyer's responsibility to either pick the items up or to arrange packing and shipping by a forwarder.
Here a link to cloud storage showing photos and other information of the units: http://e.pc.cd/o3sy6alK
More equipment to follow in a few weeks / months (will rather be elder calculators).
