I have an RX02 drive currently mounted in an external enclosure that I'd like to mount in my 11/40's rack. Anyone have a set of rails for these? Thanks! Josh

50Hz vs. 60Hz

by mross666＠hotmail.com

Thanks to all those who have responded on 50Hz vs. 60Hz So to summarise: 1. Most PSUs are unlikely to present a problem, especially since we're going from lower to higher frequency. 2. Tape drives are likely to run just fine. 3. Disk drives will be as expected (pulley issues) for older drives, but RL should work?? 4. The big 'gotcha' appears to be ferroresonant PSUs. I knew those would be a problem, but I must admit I didn't know DEC used them. OK, so we've been told the RX01/02 is ferroresonant. Think carefully folks - are there any other DEC PSUs that use ferroresonant transformers? I'm thinking mostly about logic PSUs from early pdp-8/12/15 to later 11s - 11/34, 11/73, pdp-8a etc, but any data on peripherals which used ferroresonants would also be welcome!

Spare H960 racks anyone?

Title says it all... I'm in need of a few (up to 10) DEC H960 racks in decent (rust-free) shape. Anyone who can help, please reply! Failing that I'll need to get out the sandblaster and the spraygun!

What's up with this case?

Sometimes this is for tempest compliance although I would think that if a 5170 was to be made tempest compliant, you'd need some kind of baffle over the front. And the tempest people were always real big on putting CRT's in metal cans too. Tim.

Looking for PDP-8 omnibus "top connector" blocks (or reasonable substitute)

by derschjo＠mail.msu.edu

Picked up an RK8E along with an interesting PDP-8/e system (well, interesting in that it says "digital equipment international ltd, galway ireland" on the front panel, which is something I've not seen before on a DEC product. Otherwise it's your standard 8/e...) The RK8E's missing the top connector blocks and I don't have any spares of these; are these unobtanium? Anyone have any to spare, or have suggestions on how best to make my own? Thanks, Josh

SPARCClassic won't turn on, clicking sound

by alexandre.laguejacques＠gmail.com

Hello all, I've just plugged in a SPARCClassic to 240 V 50 Hz AC (brought it with me from a 60 Hz country). Despite the power supply being rated for this, it won't start in the traditional sense of the word. The speaker makes a clicking noise when I press the power button and until I turn it off. Inside the case, everything appears intact... Thanks, - Alex

2.5" laptop SCSI drive standards?

by ethan.dicks＠gmail.com

Hi, All, I have some 2.5" SCSI drives from Thinkpads - Toshiba MK2428FB, IBM DVAS-2810, and an IBM DPRS-21215. I don't think they have the same pin arrangement as older 68K-era Mac laptops that take SCSI drives (though I could be mistaken on that). Was there more than one standard pinout in the sub-1GB 2.5" SCSI drive world? Thanks for any comments, observations, and pointers. -ethan
