The necessary memory will depend on the particular CPU board model you end up with. You have half of a UDA50. You need the other board, the two ribbon cables that connect the boards together and the SDI cable from the controller to a bulkhead. SDI is "flipped" - you always need an odd number of...

Maybe a little late. I don't know if the KA640 is smart enough to do this, but most of the later boards respond to "T 9E" with a list of diagnostics. That list does not correspond to the countdown shown on the console. If your system doesn't do anything useful in response to "T 9E", just try...

I'm just becoming active on here again, so this may be old news. I received the email from VSI and emailed them back, and posted a copy of my reply to Facebook. Here it is: "Given that this is the first community license email message I've received from you despite sending multiple requests for...

I recently acquired a key ring from a former DEC tech to augment my existing collection. I can make copies of any of the ones that are copyable - obviously not the plastic ones, and there's at least one on the ring with a restricted keyway (requiring licensee's permission to copy). Many of these...

Data General is XX2265.

15 years ago, on June 28th 2006, Alaska's Senator Ted Stevens said that "... the Internet is ... a series of tubes". While widely ridiculed at the time for failing to understand the nature of the services his Senate committee was in charge of regulating, I figured I'd take a look back on the...

For quite some time, images attached to posts only show as the smaller ones inlined in the posts - clicking on them produces the expected expanded display window with < and > buttons, but no image. For example, here. I tried looking at the page source, but it is pretty disgusting. The W3C...

It looks like we don't have a topic for these yet, so I created this one. Feel free to post any information you have regarding specific models, tips and techniques as applied to interfacing vintage computers, modems, and terminals.

I came here to give some feedback* on an incredibly annoying problem when typing replies - If I cut and paste text from anywhere else, it erases all of my carefully-composed text and replaces it with whatever I pasted. This is a new misfeature since the forum software was updated. Normally I'd...

Shouldn't the stuck crosspoint be detected as a FCG/SUPF during call setup and bypassed? This also sounds like a maintenance that should have been deferred until late night or weekend off-peak hours, unless the switch had been operating without the grid while it was out being "repaired". Since...

I'm doing the same thing, but with the Dell Studio 1558. That's a much newer (2009-2010) model, and is probably the last fully customizable laptop from Dell (just for the top cover, there were over 200 stock styles to choose from!). I have built these out to pretty insane levels of configuration...

This thread will be a "data dump" of various documents and reminiscences of Data General as I find them.

I'm restoring a DEC TSZ07 (AKA Cipher M995S, I think). The company I got it from said that when they powered it on 10+ years ago, it displayed gibberish on the front panel display and then went dead. I disassembled and cleaned it and determined that they had let the magic blue smoke out of the...

No, it just appears to be a re-spin of the older designs, since it still has the 8X305 and 3 2KB RAM chips. I'll attach 3 pictures (none taken by me) of what appear to be 3 generations of the card design. I think the standalone converter was the IRMAline and IRMAlink was the name of the file...

Found on alt.folklore.computers - Australian Computer Museum Society Inc has twelve LA120 printers surplus to their collection. Condition not stated. Pickup only (Perth, Western Australia). If interested, please click on the a.f.c link above - I have nothing to do with this beyond passing the...
