FS: Early National Instruments DM8200D Comparator
by Jonathan Chapman 21 May '22

21 May '22

All, Finally listed the National Semiconductor DM8200D that Evil Mad Scientist Labs did some super macro photography of: https://www.ebay.com/itm/275320526785 An unremarkable part for its function (it's a 4-bit magnitude comparator, it does work!), but the packaging is interesting. It's in a "ceramic sandwich" DIP, which is a piece of ceramic with a hole for the die and the leadframe in it, sandwiched between two pieces of gold-plated metal. That's uncommon enough as it is, but additionally, the pins are actually rolled instead of being stamped! Pictures explain better than words, here's an imgur album with higher resolution pictures: https://imgur.com/a/TCrIxEH Anyway, I figured I'd post here more because people might not have seen the original EMSL picture thread elsewhere. It's listed for $1 starting bid, no idea what it's worth :P Thanks, Jonathan

Simple Commodore drive question
by Kelly Leavitt 18 May '22

Is there anything special about the serial disk drive cable for the 1541s or will any straight through 6 pin DIN work? I have several drives but I don't seem to have any of the cables. Thanks, Kelly

Strange Commodore 1581 floppy drive issue
by Russell LeChard 16 May '22

16 May '22

Good Morning All. I am seeking some help from some Commodore experts with a Commodore 1581 floppy Disk drive. Some background: I've been an IT specialist specializing in IBM and compatible PCs since the early 90's. However, I started my computing journey with the TRS-80 model III and Commodore 64. I fell in love with the C64, and it began my start in a very successful career in IT. (see attach photo of my c64 setup in 1986 LOL) Recently I was lucky enough to find a C64C, a C128, and a 1581 3.5 floppy drive online for a reasonable price. Well, I did pay a premium for the 1581, but I never had one back in the day and well, I treated myself.. This past weekend I tested all 3 items and for the most part all worked OK. I was concerned the most about the 1581 working. After a delay in remembering the correct syntax for the C64 format disk command (open 15,8,15,"N0:testdisk,01": close15) - My memory isn't what it was in my younger days! LOL :-D), I was able to format a disk and then save a simple basic prg to it. However, when I try to load this basic prg (on the C64), it locks up the c64 and there seems to be no activity led lights and the 1581. I need to reboot the C64. Now, I tried the same task using the c128 and the same 1581 and floppy disk, I can now format, save, and load a basic prg without any issues. Everything seemed to work fine. My question is, are there any known compatibility issues between the C64C and the 1581 that the c128 fixed? I always thought the 1581 was compatible with the C64 and c64C? Very Strange. Any thoughts and advice are welcome.Thank you in advance. Take Care, Russell LeChard

Al Charpentier in Dave’s Garage
by Richard Cini 16 May '22

16 May '22

Not sure if anyone follows Dave’s Garage on YouTube (Dave is an ex-OS engineer from Microsoft) but he interviewed Al Charpentier about Commodore and designing the VIC, and he mentions VCFe. Dave’s a big Commodore fan and kind of grew up like many of us, using the VIC or C64, as our first computers. https://youtu.be/rs6J_PP7O7k Rich http://cini.classiccmp.org/ Long Island S100 User’s Group Get Outlook<https://aka.ms/qtex0l> for iOS

An idea for preservation and a proposal for the future of the VCF's library of written media.
by Lou 16 May '22

16 May '22

Hello all, I don't speak much on here often enough but I have been on the list and in the community for a little while now. Something came to mind the other night when I was doing research on preservation of physical book printed/written media and came to find not only several different kinds of methods and businesses that can scan these forms of media to a digital form but there are also scanners that exist which can do this job well without it being destructive to the books. The issue of course is that these scanners are by no means cheap for the average small scale user wanting to preserve a few of his books/manuals and some of the services out there that can offer this are either not much cheaper and/or only offer the destructive method of scanning this media (I.E. unbinding books to scan individual pages). After some time thinking about this, hearing some colleges and old libraries/research facilities having these for their own preservation efforts a thought came to mind...Why shouldn't the VCF have one for their own preservation efforts as well? The idea is simple enough, an investment in a non-destructive book scanner for the VCF which can be used to back up the existing library of physical written media, manuals, history, research, and more which can be put into digital form and be accessible to anyone who needs it without difficulty. It can help many countless individuals in the community who would need that information but isn't uploaded or documented anywhere else. A form of digital preservation and online library could be a great benefit to everyone. Finally, a further benefit is those who have their own materials they wish to preserve as well could do so with a suggested donation to the museum as well. It can be a service for other collectors who want to preserve their media as well and could even be added to the main library! Hosting of these materials could also be done and uploaded to archive.org to shoulder off the need of hosting our own site (unless desired of the community). It's a benefit with no real downside to the museum or the community at large. I know there will be some finer details to discuss and some minor issues that might come to light (especially anything involving possible copyright) but aside from this it can be a useful service for everyone. I just wanted to bring this idea forward to see what everyone thinks of it. Thanks for reading this out! -Lou
