I don't know if I can hold myself from bidding. Without questioning I would offer some 200 USD which is good I think (good condition of the lot as a base). And I belive ePay could push me eventualy to some 400 or so USD (Takin the 'imagine what if' measurement). Sigh. Gruss H.

UK VCF (Was: Re: Any *really* homebrewing going on?)

I would start this way, but I'm just not in the UK ...and thats what the thing was about - I already had some talks to Wirtschaften (some Pubs) over here about this, and a meeting somewhere in spring might be reasonable. But it would be a Bavarian (German) mini VCF, and beside the travel distance for our UK list fellows, the Meeting language will be German, at least for most people, since the goal will still be to attract more visitors. Of course everybody is free to use what ever language is possible to talk, but if there is a programm of speaches to be made there will be problems. On the other side, we might attract new followers for the list. So, when only looking at the list I belive a UK (informal) meeting might have more members visiting than one in Bavaria. But feel free to prove me wrong. If there is a response, I will voluntere to organize it. Gruss Hans -- Ich denke, also bin ich, also gut HRK

I think that is why you have the rather > seemingly unreasonable policies about discard equipment. Thats the simple way of avoiding any possibility, as far away it might be. An empolyee like you described could even in Germany, where we have very strict laws agains random kickin of employees, be fired winthin some days. AND will be responsible for any possible financial loss - Thats a bit like your cracy pruduct cases. So taking of parts is ok at most companies (with permission) but using them for profit (no, a single sale at a flea market is also not considered profit) could harm you more than being charged with murder. >> I think with the modern ideas about environmentally friendly disposal of >> waste it would be appropriate for the local authorities to turn a blind >> eye to 'scavengers' like ourselves and thus reduce the amount of useful >> stuff which ends up in landfill ;-) Of courese - extending the usage of any thing is the best environmental protection strategy (maybe without suizide), especialy with wares that used a lot of energy and other recources to produce - often a lot more in construction then at any time later - like cars or computers :) > Until one loathesome scavenger cuts a finger off on some particularly > sharp piece of metal and sues the owner, the trash company, the maker of > the trash container for not making it so they could get inside in the > first place, etc. (at least in the U.S.) Yes, and only in the US. Ok, our European product laws are maybe sometimes a bit week, but the combination of better rights for the customer and a very junky law system isn't helpful either. And worse, if we would bothe get hurt (in the US) I have to be lucky to get 1/20th of your payment ... American Courts are somewhat picky about the victims ... Gruss Hans P.S.: A surplus store has some PC-234 printers on sale. These are Printers for the TI-74 Basic handheld. They seem to be new or at least in very good shape in the original box. The price is some 85 Mark, so any interest ? -- Ich denke, also bin ich, also gut HRK

DOS disks?

by JRichardson＠softwright.co.uk

>> oops, that was supposed to go to Sam only. >> ELM needs a "reply to sender" key. *sigh*. In exchange the menu option is "reply to sender" but that replies to the list, despite the name of the original sender appearing in the "from" column. One day MS will write some software that works... (OK, so that's completely off-topic... but it won't be so much ten years >from now... look at it as being ahead of its time... :) cheers Jules > > >

PCjr with no disk drive?

by maxeskin＠hotmail.com

The disk drive was an option, like the hard drive on the XT. In my PCjr manual, the disk drive manual is a separate booklet. The owner was supposed to install it, I think. BTW, why is the PS/1 called that if it came after the PS/2? >drive, but instead a face plate covering the slot where the drive would >go? I saw such a thing today and was curious if there were ever any >PCjr's released without internal disk drives. Obviously this one was. > >The inside is rather bare as well.
