Re: Livingston PortMaster 2e

My experience with Livingston PortMasters was a great experience. PortMasters, Cisco 2511 w/Octopus cables, and lots of US Robotics modems encompassed my early ISP experiences. If I recall correctly, Livingston came up with the RADIUS authentication protocol, and open-sourced it for us all to

Livingston PortMaster 2e

No questions, and nothing of interest, but a quick story of success. Not sure if PortMasters are on topic or not, but I picked a 20 port unit up at VCF-SE #2 in 2014 and it has sat on my shelf for 2 years as I tried to find a large block of time to get it working. Having never used a unit in

I am up for some 100/102 talk! That unit is actually a big interest as not only are they vintage computers, but they fit in another of our displays, "The tools of the journalist" . As a matter of fact we are looking for another to go in the display in our university's journalism

What sort of stuff do you tend to cover? My interest in Tandy / RS machines is mostly limited to the Model 100/102 machines, with which I have some familiarity. The Model 100 line are my "favorite" of the early pre-PC / DOS portables. The dang things are just so friendly and usable.. and what kind

Yes I believe $A000 is covered by that heavily modded MP-M board. I think the machine is basically working optimally (except for the odd time I power up and it gives me garbage, not sure what that's about.. have to fiddle with boards a bit and then it's fine again). I ended up successfully loadin

sorry for top post-- coming from Android thing. you definitely do not want RAM at $8000 because it will collide with the I/O block that is decoded there. If you have mp-b back plane as you stated then i/o occupies $8000 to $9fff and so RAM needs to start at $a000. The modified mp-m is to make

Josh, The HP 110 uses the same ac adapter (8V AC) as the hp 41, 71b and 75 series. Those are also used for some hp peripherals. I got lots of them but am on the wrong side of the big water. But it shouldn't be too difficult to get one. The batteries of the hp 110 are sealed lead acid types, the

It must be a IT-28. It has a 500V leakage check. It is not a high precision device but it will be useful. I do have a precision LRC bridge made by Marconi that I can use for those purposes. It has a quick check type large range scales. It is more useful for quick checking. My main issue right
