Anyone know a good rs232-based programmer? I have a willem (great unit, use it all the time, hate the switches), and a Gq-4X USB unit (nice unit, no switches, A14 is a bit weak and won't program my ROM-3l 23128 devices). But, I was considering setting up a small set of scripts on a UNIX/linux box here that could program items via a menu, and thought a serial (or usb serial) would be easiest to script. I could grab an older unit (though I didn't turn up promising links in half hour os searches tonight), but I'd prefer it support at49F series FLASH.

Kaypro II floppy identification?

by xmechanic＠landcomp.net

OK, so I dug the Kaypro II back out of storage now that I have some usable floppy disks, thanks to a good friend. :) Anyway, I found out that the current A: drive wasn't being detected in the BIOS on my disk creation machine. B: disk works fine. Checked all connections and made sure everything was seated properly, and still no luck. So I pulled both drives and inspected everything and then just swapped positions and re-installed them, hoping that the different positions on the cable was what selects which drive is which. Well, not so. The machine still tries to select the original A: drive. Is there a jumper setting on these old full bay 5 1/4 floppies to select the drive ID? Any ideas? -- Dave Land Land Computer Service Check out my site at http://www.landcomp.net

Compaq Portable II Power Supply schematic (or capacitor ID)

by derschjo＠gmail.com

Powered up an old Compaq Portable II and was greeted with a cloud of smoke; a tantalum cap's gone to capacitor heaven (it's next to silicon heaven).Unfortunately it's now so far gone I can't read its value -- anyone have a schematic or know what the capacitor at C19 is supposed to be? Thanks, Josh

OT: 1000 year DVD storage

by barythrin＠gmail.com

You will but you won't have the sata connector. I guess its immune to that bacteria or fungus and/or scratching of the label? I've had lots of cds I've burned go bad in their padded cd holder. (Holes/flakes in the label) making it a seemingly poor decision unless I burned 2 or more of each archive. ------Original Message------ From: Chuck Guzis Sender: cctalk-bounces at classiccmp.org To: General Discussion On-Topic and Off-Topic Posts ReplyTo: General Discussion: On-Topic and Off-Topic Posts Subject: OT: 1000 year DVD storage Sent: Mar 19, 2013 3:54 PM The M-Disc claims 1,000 year permanency. http://www.mdisc.com/ Anyone have experience with these? --Chuck (wondering if we'll be able to find a 1,000 year old DVD player)

Selling a DEC RX02 on Ebay

I got one with my 11/750 15 years ago. I sold it for around $200, close to what I paid for the entire system. It was a local sale and I don't recall the drive's weight. alan

Homebrew mark-sense card reader or other?

by earl＠retrobits.com

Hi all, I need another project like I need a hole in the head. However, I am definitely on the prowl for a way to store and retrieve information in a more physical fashion. Something like a tape punch/reader, or a mark-sense card reader. (I'd have to find or print some mark-sense cards...) Back in the day I used punch cards, mark-sense cards, and paper tape. There's a certain "coolness" to actually seeing and holding the data in a physical format. I think it would be great for my kids to see, and/or help me build a physical storage device, to give them a more visceral sense of computing. You can't exactly see the bits in a flash memory chip. All that said - I've looked for homebrew projects of this type, and haven't come up with any great candidates. I'm not the most skilled person at mechanical stuff, so I do seek a starting point for ideas or plans. Anyone have any comments/suggestions? Goal would be a method to store (could be as simple as #2 pencil), a method to read, and a serial RS232 interface (that part I can build). Thanks! - Earl

BB-M448B-BC DECNET11/M+ V2.0 DECKIT?

by bob＠jfcl.com

Bitsavers has the file BB-M448B-BC_DECNET11M+_V2_NETKIT_1984.tap which is (sadly!) exactly half of the DECnet-11M v2.0 for RSX. Missing is the corresponding DECKIT tape. I know it's a long shot, but would anybody out there have it?? Yes, bitsavers does have the NETKIT/DECKIT pair for V3.0 and V4.2, but I need the older version. Thanks, Bob Armstrong

FS: various (old) 68-pin and 50-pin SCSI disks

by marcogb＠xs4all.nl

Anyone interested? Pretty much everything from 1 Gbyte to 9.1 Gbytes that can go, from various vendors (Seagate, Compaq, Quantum, Micropolis, IBM, etc.). The disks have recently been tested. Furthermore, the disks are located in the Netherlands and I will happily ship to wherever desired and covered for. - MG
