Hey all -- Working on bringing a Dasher D200 terminal back to life. There's a bridge rectifier package that appears to have a short in it and I can't find any info on it -- I suspect it may have a house part number. It's got a Motorola logo on it, and is labeled "SDA314." In the schematic ( http://bitsavers.org/pdf/dg/terminals/014-000640_DASHER_D100_D200_Display_T…) it's CR6. This short causes the 5W resistors before the fuse to smoke and explode, but the fuse is fine (thank goodness.) :). Anyone have any ideas? Thanks, Josh

DEC SIMMS

by useddec＠gmail.com

*I found a handful or two of 54-20410-01 and a bunch of 54-20352-01, but have conflicting info on what systems they are from. Does anyone have any info on them or need any?* *I'm also looking for a list of DEC simms. A fellow list member was kind enough to send me the following link.* *http://www.chrisjdoran.plus.com/simms.html <http://www.chrisjdoran.plus.com/simms.html>* *Any info would be useful.* *Thanks, Paul*

ISO: Scan of IASIS ia-7301 ("Computer In A Book") manual / text

by derschjo＠gmail.com

Hi all -- I picked up a nice IASIS ia-7301 (see: http://www.old-computers.com/museum/computer.asp?c=544&) recently. It came with the binder and the computer but none of the paper bits. Does anyone have the manual scanned (or is there anyone who might have a copy to scan)? I'd like to print a copy to put in there. My searches on the 'net have come up empty. Thanks as always, Josh

German Translation, Serial Port?

by w2hx＠w2hx.com

Hello friends. I need a translation from a German manual describing serial port parameters. I used google translate but it doesn't quite give me the warm and fuzzy. Anyone here speak German? Here is what it says: Betriebsart: Asynchron 16 Zeichenl?nge: 7 bit (mit Sperrschritt) Parity: gerade L?nge Sperrschritt: 1 bit Google says: Operating mode: Asynchronous 16 Character length: 7 bit (with blocking step) Parity: straight Length of blocking step: 1 bit First, anyone have any idea what Asynchronous 16 means? (async I get, but "16"?) 7 bit with blocking step. Could this mean 7 bit with stop bit? Parity: straight. Could this mean odd or even? Length of blocking step. Could this be number of stop bits? I am attempting to translate some pages in this manual and would like to get this right (for others who may find this info useful). Thank you!!! (or should I say Danke?!) 73 Eugene W2HX PS. This is for an HF antenna coupler that can be controlled over a serial port.

Clock batteries...

by w9gb＠icloud.com

Not exactly. The TL-5242 is more than 3 times the price and chemistry difference. I assume you do not desire to replace the Lithium Coin Cell ? or can?t find? Tadrian TL-5242-W Lithium battery https://www.mouser.com/ProductDetail/Tadiran-Batteries/TL5242W?qs=Yk42LiOZU… Data sheet https://www.mouser.com/ds/2/474/TL-5242-W-1214138.pdf BR2335 Lithium Coin Cell w/solder terminals (BR2335-T3L) After Panasonic purchased Sanyo, a decade ago, they control about 70% of the global lithium coin cell market. https://industrial.panasonic.com/ww/products/batteries/primary-batteries/li… Panasonic refers to your solder terminal profile as ?Type G?, 3-pin mount. They have designated a suffix for each style, in this case GUFN or GUN. == Panasonic BR 2330 ?Type G?. Suffix: GUFN (yellow insulator) and GUN (no insulator) Size and mounting identical. 255 mAh rating. The GUFN at Mouser for $2.05 each (not currently in stock) https://www.mouser.com/ProductDetail/Panasonic-Battery/BR-2330-GUFN?qs=rqxQ… Panasonic Data Sheet https://industrial.panasonic.com/cdbs/www-data/pdf2/AAA4000/AAA4000D95.pdf Ray-O-Vac BR 2335-T3L Lithium Coin Cell, 300 mAh Data sheet http://farnell.com//datasheets/1728610.pdf?_ga=2.53046696.1289741559.153343… Where to BUY ? Solder Tab lithium batteries are used in MILLIONS of Mobile devices (Toll Road transponders, various auto/truck dongles, etc.). Electronics Distributors: Digi-Key, Mouser, Future, Allied, and Newark/Farnell stock these lithium coin cells. In addition, Batteries Plus retail stores (across North America) have Solder Tab Welders ?on premise? and can create the coin cell you desire (Just In Time needs). This consumer convenience is higher in cost. Lithium Coin cells are PROHIBITED from domestic Air Shipment (USPS Priority Mail) ? SO shipping costs can be higher and require longer time. I order my needs 2 or 3 times each year, of the most popular profiles. Panasonic Lithium Battery Catalog (circa 2015) https://industrial.panasonic.com/ww/system/files/data/download/catalog/id_l… greg == Does anybody know if external 3.6 VDC batteries, like the TL5242, are the counterpart for on board 3.0 VDC batteries, like the BR2335-T3L?
