Here’s what I did (but I wasn’t space constrained as I have the equivalant of 4 RP06 drives). You’ll likely have to configure the kernel. This is easiest done within an emulator, as it took 24hours on my 11/70.

That will also tell you what you can reasonably fit on two RL02 drives. Also it’s easier to “back up” and start over if you make mistakes (save a version of the emulated disk files before making substantive changes and copy them back if you screw up). Once you have something working reasonably well, you can transfer the “bits” over to your 11’s RL drives though your preferred method. TTFN - Guy

It was very convenient to be able to stick the ZIP cartridge in a drive on a PC for access from simulators etc. I used it with RT11, RSTS/E, and BSD. 100MB might not be enough to be interesting for general purpose use on a PC any more, but it's fine for a PDP-11.
Re: 2.11BSD on two RL02 drives? Probably not, but...
You might consider just adding another storage controller. I'd recommend something that talks MSCP. SCSI seems to be what most people are after nowadays, but ESDI controllers are much cheaper, and the drives aren't that hard to find. If you have SMD drives kicking around already, there are SMD MSCP interfaces that also work well. I've had excellent luck with Emulex MSCP controllers.

You can do it with third-party controllers like Qbus Sigma, DSD, or MTI using standard Shugart interface disk drives. Some also support "RX03" double-sided drives. You could also clone a formatted double-density disks with a flux-level reader/writer board. RX02 drives can "reformat" RX01 media to RX02. So if you need RX02 media any soft sector single sided single density (26 by 128 byte sectored) will do. I use my S100 CP/M system to format media to that then the RX01 can be used to init (initialize directory) or reformat (to DD). Least the PDP11 can. Allison

Re: WTB: RX02 Floppy Disks
Hi All, Have managed to find and pick a bunch of SSSD 8" Disks in my basement, and have formatted them now via the IBM /23. Over the weekend I try the next step,and will "format" them under RT11. So fingers crossed, that my only running RT11 system, installed on an DEC RC25, will still boot. Many Greetings Ulrich

Best example is the case of one seller who deliberately put up an auction for a car with a starting bid of 1 Euro. He didn't want to accept the (only) bid at that price but instead, insisted on a much higher value. He (the seller) was convicted to pay the difference (several thousand euros) to the buyer because the sole fact that he put up the car at that low price doesn't voids the auction. On the contrary, it is the spirit and purpose of an auction to make a bargain (on the buyer's side) or to realize a higher price (for the seller). Christian

I've never gotten a response from any ebay protest during this sort of behavior as well as worse. Ebay should be subjected to some auction laws, which would ban that practice, as an absolute auction with a final result. But what they do for auctions are not auctions by most legal definitions, and I don't think any legal attacks have succeeded. The auctions are mostly like silent absolute auctions which are used by some, and may be exempt from rules about making good on the delivery of items in law. IANAL thanks Jim

Re: WTB: RX02 Floppy Disks
Hi All, Looks like I was wrongly under the impression, that there is no way to reformat, disks to work in an RX02. I have two working IBM System /23 with 8" Floppy drives, which can format also in IBM3740. So when I have understood it correct, it could be worth to simply format an 8" SSSD Disk in 3740 format, followed by: ".FORMAT DY0:" ".INITIALIZE/BADBLOCKS DY0:" under RT11 which will end up in an RX02 formatted disk - Correct? Many Greetings Ulrich

Re: Sperry UTS 40 on EBay - Statesboro, Georgia
If the item ended normally at its listing time, which looks like it did. The seller can do what he wants. If the seller removed it and brought it back at a higher price, its hits one side of a gray area. if the seller removed the item and there were bids against it, eBay will take an interest in the seller and ( via its database's ) watch what goes on which is ... If the seller has a pattern of doing the able, and if the seller is a small fish, good chance the seller will be gone ( and usually come back under a different name, all it takes is another bank card and address, like say his brother or buddy down the street) If above and the seller is a big fish, say around 5,000 or more items at a time, the seller can do what the heck they want and eBay wont do a thing.
