pdp11 MicroPower/Pascal
Hi, Would anyone still have a copy of latest pdp11 MicroPower/Pascal? I'm trying to have a retro programming contest / party at my house and want to feature Pascal along with Macro-11 and maybe c on a real 11/23 with RL02s under TSX. Hoping to hang like ten users at once on the 'ol girl and make 'em really feel the speed. I might let up a little and run the contest on my 11/73 with scsi if it's too terrible :) Anyway, looked around the net for hours and can't find a copy of MicroPower/Pascal, so if anyone can help, I'd be grateful. Found TSX-Plus, though! Big Thanks again to Lyle and whomever's running the classiccmp site these days! --jake

I have one or two packs and a drive in the museum but that's all. If I had a surplus of packs I'd be happy to share...

Thanks everyone for the information -- that definitely looks like the same drive mechanism. I had no idea HP sold a drive like that. I think I may wait for the price to come down a bit on those packs, though :). - Josh On Fri, Jan 10, 2020 at 1:23 PM Al Kossow via cctalk wrote: > some packs > https://www.ebay.com/itm//362021616865 > > On 1/10/20 1:12 PM, Al Kossow via cctalk wrote: > > and it looks like I have a pc board > > > http://www.bitsavers.org/pdf/hp/disc/photos/7907/07907-60003_7907_DTC_488_F.jpg > > > > The controller was made by DTC > > > > On 1/10/20 1:09 PM, Al Kossow via cctalk wrote: > >> here is the disk > >> https://www.hpmuseum.net/display_item.php?hw=561 > >> > >> the hardware support manual is 07907-90903 > >> > >> On 1/10/20 1:06 PM, Al Kossow via cctalk wrote: > >>> yup! that looks like it! > >>> > >>> On 1/10/20 12:02 PM, John-Paul Stewart via cctalk wrote: > >>> > Is it from the HP 7907A drive?

Pro-380 power supply
I have a Pro-380 with an H7862-C power supply. Recently the power supply input filter (where the cord plugs in) shorted out, causing melted filter guts to leak out of the case and put a big smoke cloud in the room. Fortunately I have a spare, but it's an H7862 (not -C). I'm planning to replace the failed input filter, but in the meantime: does anyone know what the difference is between the two versions? Is it just a design tweak, or does the -C have different specs (like higher current ratings)? The replacement came out of a Pro-350 component set. paul

LIF filesystem under linux
Hi list, is anyone aware of a LIF filesystem implementation for Linux? I'm aware of lifutils, but i'm looking for filesystem integration either via fuse or via in-kernel module. Haven't found anything on the internet. Thanks Sven

There were three different companies that made 8" drives like that, Amcodyne, Datapoint/Honeywell-Bull, and CDC I don't think the packs were interchangeable.

Re: Info / packs for Amcodyne 7110 "Arapahoe" drive?
Right off the bat it looks like a CDC Lark pack. Wonder if the whole thing is a re-badged Lark. Once I get these RL02's out of the way I'll drag my Lark out from the shed and start looking at it. If I recall one drive is in the shed, one in the attic along with the power supply. Then again I thought I had one Porsche 911E fuel pump in the shed, but that was sold years ago. Hm.

I'm guessing that these packs were specific to this drive and not any sort of standard, and that tracking one down is going to require quite a bit of luck. Figured I'd start here :). Also looking for technical info (pinouts for the power connector would be a good start...) Thanks as always, Josh

HP used them in one of their disk products, that is probably where the eBay guy pulled the drive from, since he has a LOT of HP disk parts he's been selling off. I also have a couple of the drives, w/o media or any more docs. If we can identify the HP product, its early enough that HP would have printed a good service manual.
