Anyone know which Lucent semiconductor device or devices were used in the first Apple AirPort, the Lucent board was " Lucent WaveLAN Silver PC Card" but I'd like to know the devices used. Tom

Re: Extracting files off “unknown” 8 inch disks. Any thoughts…

by terry＠webweavers.co.nz

Hi, Just an update on this. I still haven't got those 8' floppies of unknown origin to play with but I HAVE made a lot of progress with my own disks. Thanks to everyone who gave me help with this. Here's a writeup for those interested: http://www.classic-computers.org.nz/blog/2017-04-15-adventures-with-an-8-in… Terry (Tez)

cctech Digest, Vol 34, Issue 15

________________________________________ From: cctech [cctech-bounces at classiccmp.org] on behalf of Tim Mann via cctech [cctech at classiccmp.org] Sent: Sunday, April 16, 2017 8:13 PM To: cctech at classiccmp.org Subject: Re: cctech Digest, Vol 34, Issue 15 Brief comments on a couple of topics... I hadn't heard of the MISE or M3SE before, so I googled. Remarkable projects. It's pretty tempting to get an M3SE to play with on the Model 4P that I bought as a reference platform when I was adding 4P support to xtrs. (I don't have any other physical TRS-80s anymore.) Time continues to be a big problem in the way of doing retrocomputing stuff, though. _____________________________________________ Definitely worth it. It will boot directly from the M3SE making it a lot easier to do stuff. And with the FTP capability I just had an old BASIC program I ran years ago that I wanted to revive. Used FTP to move it back and forth between my Model 1 and a Unix system in order to have a real editor for fixing all the mistakes. Then used FTP to move the program to the 4P to test it out there as well. Never realized the speed difference in the various models until I cold run stuff like this side by side. bill

Speaking as someone else with the lack of time issue these days, the M3SE makes using the TRS-80 so much simpler and easier that you get to actually spend time using it rather than spending your little spare time getting it working.

Extra copy of DOS Programmer's Handbook available

by useddec＠gmail.com

Hi Noel, I don't think I need it it but I know someone on the list for about a year that probably does. Let me know the status. Can you call sometime this week? Thanks, Paul

Program Logic Manual (PLM) for APL\360 or APL.SV?

by spacewar＠gmail.com

Did IBM publish a Program Logic Manual (PLM) for APL\360, APL.SV, or any other APL language implementation, as they did for e.g. their FORTRAN(E) and PL/I(F) compilers?

Harry Huskey, Bob Taylor -- sad news

by jnc＠mercury.lcs.mit.edu

> From: Al Kossow > Harry did an oral history at CHM There are also a pair at the Smithsonian: http://amhistory.si.edu/archives/AC0196_husk730419.pdf http://amhistory.si.edu/archives/AC0196_husk720309.pdf and the CBI did one too, but alas it does not seem to be on-line (it's not in their OH index, and although Google searches for other ones from there turned them up, not this one): Harry D. Huskey, OH-83 Interviewer: Christopher Evans Date of interview: 1976 Anyone have a pointer to it? Noel

If C is so evil why is it so successful?

by jnc＠mercury.lcs.mit.edu

> From: Alfred M. Szmidt > No even the following program: > int main (void) { return 0; } > is guaranteed to work I'm missing something: why not? Noel PS: There probably is something to the sports car analogy, but I'm not going to take a position on that one! :-) Interesting side-question though: is assembler more or less like a sports car than C? :-)

Looking for PDP-8 G603 "Memory Selector Matrix" boards (or dec T-2052 transformers)

by derschjo＠gmail.com

Hi all -- I recently got insanely lucky and scored a Straight-8 (S/N 14). It made it in nearly one piece from Ohio, but during transit, all of the G603 Memory Selector Matrix boards fell out. It looks like on early revisions, there was no bar in place to hold the boards in (or someone removed the bar from this one, but I see no indications that this was so). So while the rest of the flip chips were secured, I overlooked these in guiding the seller in prepping it for shipping. Two of the boards sustained pretty major damage, about a half a dozen of the little "gum drop" looking transformers (DEC refers to them as T-2052) broke off and most of them fell out and will never be found again. I realize it's a long shot, but does anyone have: - Any spare G603s (working or no, as long as the transformers are there) - Any spare T-2052s (or know of a source) - Any idea what the T-2052 *was* so I can try to replace them. I haven't found much detail as of yet. (The G603 schematic is here: http://svn.so-much-stuff.com/svn/trunk/Eagle/projects/DEC/Gxxx/G603/G603E.p… ) Thanks, all! - Josh
