I feel a little silly asking this, I hope it is not an overly inappropriate request for this mailing list. But does anyone here in the States happen to have a stack of known-good 5.25 disks they don't want anymore? And more specifically, would it be possible for anyone to image such a disk with a copy of PC-DOS 2.0 or earlier? (and maybe on up to 3.3 or so) The later part is the service that would be more helpful to me. I finally have a drive for an old system that currently uses bubble memory cartridges to boot to PC-DOS 2.0, and so we'd like to see if (using these external drives) it could also boot to a (confirmed legit) image of IBM PC-DOS (and/or very early Microsoft DOS). Or, do we still need some kind of proprietary Sharp DOS image? (in which case, extra blank disk would be good, as I think there are tools on these bubble memory cartridges to initialize disks accordingly). An actual 160KB formatted PC DOS 1.0 would be fantastic to have on hand - but the 180KB slightly later image would be fine also (and then also to experiment how far "past 2.0" that this system might support, if at all). For shipping/delivery purposes, I'm in north Texas. When I got these drives, I then realized I no longer have any 5.25 floppies anymore - and even if I did, then I'm not quite sure how to get the images on there (did anyone ever make a "USB-to-5.25" drive? I have a couple 3.5 versions of those - maybe the power to motor the 5.25 is too much for USB? :D ). Thanks, SteveL

Does anyone have a VT52, TU56 controller, or Apple II rev 0 available for sale?

by Ryan de Laplante (Personal)

If you or someone you know might be willing to sell, please contact me off-list. I'm in Canada, near Toronto. The TU56 controller is for a PDP 11/45. I know about the VT52 in Australia on eBay right now. Shipping something that large and heavy from Australia is too much, and we have different electrical outlets in North America. I'm also looking for certain NightOwl shareware CDs from the BBSing era: 1 - 9 (except 4 and 6), 24, 26, Games #1, Games #3, Windows Vol 1 & 2. Maybe some Boardwatch magazines as well. Anything BBS related.

Microsoft & Apple

by Murray McCullough

I had not realized it was 27 yrs. ago that Microsoft ‘gave’ Apple $150-$200 million. It was done to keep Microsoft safe from regulators - for its monopoly practices. Later did the lawsuits end between Apple and Microsoft. Did this save Apple? Haven’t researched this enough to deduce a learned response! Happy computing, Murray 🙂
