I picked up an interesting bit of hardware on ebay. It's one of these without components: http://www.amiga-hardware.com/showhardware.cgi?HARDID=1360 Does anyone have a way of getting at a component list for this? brian

HP Firesale (Jay West memorabilia)

by frebird2＠swbell.net

Yes, you can own a piece of computing history. Jay West - the man, the myth, the legend - has spent a few cycles using THIS equipment. What we have here folks is a working, rack mounted, HP 9000 K class box. At least it was working when we shut it down 5 years ago. My memory is a bit fuzzy, but I believe that all of the processor slots were filled and it may have been maxed out on ram as well. Peripherals include: (2) HP 6000 SCSI SX-W rackmount enclosures each with 4 gig scsi drives. There is a 3rd drive bay - but I forgot to write the model down. It is larger (8u) than the SX-W boxes. A second HP rack contains (2) Surestore E disk array 12H (also known as AutoRAID) -- each with 12 drives. They appear to be a mix of 4, 9 and 18 gig drives. At least that is what is marked on the drive caddies. Completing the lot is a Citoh 800Q printer, and a Printronix MVP printer. If you act fast, I'll even throw in not one, not two but (3) DTC 72MX's AND all the cabling! I also may have all of the original, printed documentation to go along with this treasure. With a deal like this, how can you refuse? All offers, reaonable and unreasonable accepted. Location: St. Louis. If someone doesn't want this, e-recycling is the next stop.

Anyone doing a shipping run soon???

by curt＠atarimuseum.com

Hi, I am purchasing a piece of manufacturing equipment from Wisconsin and I'm located in New York. Unit is a cabinet styled device, roughly the same as a Vax 11/750 unit, about 300 lbs. Anyone doing any runs in the Midwest<-->North East anytime soon, otherwise I'll have to call a freight carrier, but I prefer someone on the list who knows how to properly handle larger size electronic devices. Thanks, Curt

Looking for CMD CQD-220A /223A EPROM images

by Bernhard.Wulf＠shell.com

I would love to get EPROM images for a CMD CQD-220A/223A with the Tape AND Disk function in my inbox. Currently only having the Tape OR Disk function and really keen to do the brain surgery. The results Glen found recently are promising and I'm quite positive to successfully modify my controller as well. Does anyone have a CMD CQD-220A/TM or CQD-223A/TM and an EPROM programmer or other means of reading the EPROM images that could send me a copy? Your help is highly appreciated Thanks & Regards.

Discferret questions

by dgriffi＠cs.csubak.edu

I'm looking at my aging desktop machine and realize that its replacement probably won't have a native floppy interface, so I started thinking about the super-powered USB-floppy interface previously discussed here. I forgot what it was called, so I stumbled across this page: http://www.deviceside.com/. I quickly figured out what I wanted was the Discferret. Does anyone know anything about this anemic alternative? This led me to some more questions: 1) Can the Discferret handle flippies? 2) Can I daisychain two drives to a single Discferret? 3) How much more work would it be to make a Discferret talk to an 8-inch drive? I'd buy one or two now, but finances aren't that great right now. -- David Griffith dgriffi at cs.csubak.edu A: Because it fouls the order in which people normally read text.

(adding subject line back) In this case I think the load should be there because it is the right hand PSU that won't start, this powers the 6 slots on the right and these contain the memory and CPU, so there should be enough load for the PSU to work. There is indeed a resistor card in the leftmost slot, but the left hand PSU lights up fine. Regards Rob

Bringing tapes to Room Temp?

If they've been stored under poor conditions for 20 years, I'm not sure exactly how they're treated in the next few days is gonna matter. If they had data on them and had seen temperature swings, you might want to retension them before using. But if they're blank and gonna be used for testing the transport anyway, hard to see how this can matter. I would be hesitant to retension a tape with valuable data on a drive that had the head in contact with the tape. (Stiction). Retensioning is far from a cure-all. Why does the concept of retensioning exist at all? If a tape is stored under adverse temperature or humidity conditions, the different rate of thermal expansion of the reel and tape, or between the inner tape and outer tape, can cause "bumps" to form in the winding and require an uneven rate of rotation of the hub to spool off the tape at 25 IPS or 75 IPS or whatever the drive runs at.

DSD-80 debugger...

by geneb＠deltasoft.com

I've been asked to re-instate the download for the DSD-80 full screen debugger that I had up here: http://www.retroarchive.org/cpm/lang/lang.htm Since TCJ is essentially dead and buried, does anyone know who I can contact in order to get some kind of permission to put that back up for download?
