Thank you Tim! In 1972 I was offered a PDP-8I used (clean) for $2000 I should have save for I'd just bought a new truck ($2100)... Allison

Eventual fate of our machines

by jsalzman＠hersheys.com

> >Kind of a life time rental agreement ? >Sounds interesting. This might be a good idea. >But won't the mony winn over the idea ? There's always that issue. I find it analogous to retirement homes in this area. People 'buy' a retirment home, townhouse, apartment, etc. for a fixed price and then live there. When they die, it belongs to the retirement home to sell again. The cycle continues. If you've seen some of the homes around here, you know they've been around for a while. Part of the charge funds maintenance fees and lawn care (the latter not being important for computers). The continuous re-renting of the property helps keep the available funds around to maintain everything. I'm not saying that the 'organization' fund for maintenance to whoever rented the computer, but the concept is similar. The end goal in this case is to do what's possible to keep it around for the next person. >But, if we could keep it to a small and more individual to >individual base, I'm in. Do I hear charters? > >> Some of the funding can also be used to provide insurance coverage to >> members by people who know the value of what's being insured. > >Thats a very dangerous terrain. I do agree with you. Here, in the state of Pennsylvania, insurance of any type is heavily regulated. It may not be as bad for other states or countries. > >

RT-11 on 8" media

by jpl15＠netcom.com

Some Newby-ish questions, if it so please The List: In a box of Stuff, I got 2 cartons of BASF 8".... one of which is marked "RT-11 V3 System DO NOT OVERWRITE!!!". And inside are 7 floppies, each with a DIR printout stuck in the envelope, (and the DIRs look like typical RT-11 files). These disks are numbered 21 - 26 and 30. The other box has no IDs of any kind, save three diskettes are labled 47, 49, and 50. The other 7 are unadorned, but they appear to have been spun... there are faint burnish markings on the surfaces. As an added, extra bonus, there is a listing of an 18-line Basic program which "Determines if One Number is a Factor of Another".... surely an unexpected blessing. All this absurd and useless detail aside... I am wondering if there is a 'Minimum Set' of files, which placed on a floppy(ies) would boot a PDP11... and, I am assuming, it would require Sysgenning? Is there available on the Web this info? Also, I have an 11/73 with RT-11SJ V5.0.... it has an 8" drive. What would I have to do to make a bootable minimal floppy on this machine? In other words how few files can one get away with to wake up a PDP11 with only an RX02 clone as it's mass storage? Bowing before the Silicon Slippers of the Knowledgeable Ones, Cheers John PS: Learning all the time..... TIA!

Eventual fate of our machines

by jsalzman＠hersheys.com

> >there is no one to carry on the tradition. I shudder to think about the >eventual fate of all of our collections. Do we need a national repository >for all of this stuff? How about a collector's organization which can act as a willed beneficiary for collectors. A board of directors can act in the best interest of the collection should a member (or non-member?) die and bequeath(sp?) his/her computer collection to the organization. Some items can be kept for a museum piece while others can bid for a chance to purchase the remaining items. This could fund the organization. The organization can also conduct interviews with bidders to determine if they are serving the best interest of the computer collection if they get the desired item. A clause can be put in to require the item to be retired to the organization upon their death. Some of the funding can also be used to provide insurance coverage to members by people who know the value of what's being insured. Just my thought, and is well open to discussion. Jeff Salzman >

The PDP lives! To the best of my (limited) knowledge, anyway...

>RT-11 is available on the net at... > >ftp://gatekeeper.dec.com/pub/digital/sim/software/rtv53swre.tar.Z Correction - it is available ONLY FOR USE WITH THE SUPNIK PDP-11 EMULATOR. The hobbyist license which comes with it does NOT permit use on real hardware. >If you find it on media you are permitted to use it as a hobbiest. Again, ONLY with the SUPNIK emulator.

Somebody has a C65 on eBay

>There's some evidence to suggest that the Lisa is the Apple VI, which raises >the question of what happened to IV and V. I think it would be more accurate to say that Apple considered naming the Lisa the Apple IV. "Lisa" was originally just a code name, after all.
