As most academics often overlook the technical aspects. Where the 1925 FET is a voltage operated device whereas the Bell Labs Transistor is a current operated device. Two completely different animals Also, you how many of the innovations occurred in the past A lot of it was based on popularity, just look at Edison/Telsa And the 1925 FET was hardly on anyone's "radar" otherwise why did they spend the next 30yrs with vacuum tube computers iso of researching and developing that new innovation further. But it also had mostly to do with making the planar process practical enough to mass produce. Dan

Forgot to mention this. Tomorrow I'll be part of a roundtable discussion at an NYC meeting of the International Federation of Information Processing's history .SIG. I have 15 minutes to talk about early British mobile computers. Going to focus on Husky (which should be famous but isn't) and Psion (which needn't be famous but is).

Good source for eproms?
by Jason Perkins 26 May '16

26 May '16

I'm trying to get a Plus HardCard going again. Like many the ROM has forgotten some of its bits so I want to try installing a freshly flashed one. What's a good source for 7264s? Is it worth trying to get used ones on eBay? While I'm at it I'd like to track down a 2732 for an Apple ProFile formatting rom. Thanks, -- Jason Perkins

And now that the pentagon is getting rid of 8" floppy disks by the end of 2017, without the military needing replacements, I bet this is the end of newly manufactured 8" floppies. I better get used to baking my old floppies for reuse. https://www.yahoo.com/news/us-nuclear-force-still-using-floppy-disks-report… Cheers, Corey corey cohen uǝɥoɔ ʎǝɹoɔ

Saw this on Reddit, completely amazed... http://tubetime.us/?p=346 I am familiar with their 555 Timer IC project, and saw that they had a follow up project with the 741. Had no idea they'd take it this far. :) -Todd

ADTPro help
by Evan Koblentz 25 May '16

25 May '16

I last used ADTPro about a year ago. It worked fine. A few months ago I installed a new mobo/memory/processor in my daily PC (still running Ubuntu). Yesterday I tried ADTPro again and got this error message: "There are no serial ports, or the serial library RXTX is not installed or visible." Paul H. suggested that the adtpro.sh file was looking in the wrong place for RXTX. Made some tweaks but it's still not working. Note also that ADTPro has its own copy of RXTX in a subfolder. Stephen E. also tried to help. Can someone who is experienced at both ADTPro and Linux (and who has the patience to walk me through this) help me, please? Hoping to get some help via telephone or Skype today/tonight if possible.

Thanks for clearing that up. I wasn't sure which was official and which was informal. I thought it was the rated PG vs. rated R.
