My references tell me that the PC (thus, slot 5, nearest the P/S) is peculiar, but nothing is strange with XT slot 8 -- at least, according to my references. FWIW, I've run a variety of cards in XT slot 8 and PC slot 5 with no problems. manney(a)nwohio.com "Would a skinny ballerina wear a one-one?"

eBay and online auctions

by rexstout＠ptld.uswest.net

Wonderful things, but.... I was looking around on eBay, and found several things that cought my eye. Hey, there's a Mac IIx 2/40 for $2! But pay another $20-50 more for shipping? I could probably find it for the same price or cheaper locally. Well, it will take some time... The most recent IIx I've seen for sale(although much more RAM/HD) is $175. But I HAVE seen them around(before I got interested in collecting computers) for anywhere from $10-500. It's a crazy world... Everyone always asks me why I don't have a C64 or TRS-80 or any of those type of computers. Well, I was offered a TRS-80 Model 4, I offered $5 for it, he responded that he didn't even sell it when he was offered $75 a few months earlier. I either run into people trashing or giving away their computers(Series/1, Apple IIe, PS/2 Model 50Z) or they want to sell them as antiques(and at prices much worse than any antique store I'VE ever seen...). Would someone hurry up and invent a time machine? Zip back about 5-10 years ago when people didn't really care either way and pick up some collectors pieces for $5 and come back to the future where people sell them for $500... <sigh> -JR http://members.tripod.com/~jrollins/index.html http://www.geocities.com/Area51/Lair/1681/

dBASE II manual

by higginbo＠netpath.net

Anyone have an extra dBASE II manual they'd be willing to part with? I've got dBASE II in ROM on one of my GRiDCASE 3 laptops, and would like to learn more about it. -John Higginbotham- -limbo.netpath.net-

Sharp MZ-700

If you don't want to keep it, e-mail me >privately and I'll pay to have it shipped to me and I'll hold onto it. Sorry. :) I don't mean to say that I would dump it - simply that as I cannot repair it myself, is it worth paying for someone to do that or would I be better off just keeping it as a record, and looking at the manuals as the main part of the deal (for now). Mostly I like to display my computers as working systems (although I ran out of floorspace months ago), and so prefer working models to broken ones. :) I figure that it is better to have a computer working than broken, so long as I can afford to get it fixed - but I refuse to trash any of my systems, no matter what the problem. And this goes triple for anything that I only have one of anyway! I got very angry at a local dealer recently, for he trashed some 30 microbees 2 weeks before I got there. I had been searching for a Microbee for about 6 months, and he was supposed to sell second-hand 8-bit systems as his business. He said he never liked Microbees anyway. :( I finally got one, but if I could have saved those others I would have been able to offer them (for shipping) to the list. Microbees, for those who haven't heard of them, are neat little cp/m systems that were designed and built in Australia - not many computers were made here, although there were a few, but the Microbee would be one of the two most significant locally made computers.

Plastic yellowing

by aaron＠prinsol.com

Does anyone have a remedy for bad case yellowing? I have the suspicion that it's a permanent chemical change, but I thought it might be worth a shot. For most of the systems, I don't really mind and for some, it adds to the character. The only one that's bugging me is my Atari 800xl, which was my first real "programming" computer. Thanks, Aaron

UCSD Pascal on Europlus (was: Are We Not Men? (& Women?) [OT^2] (Was Re: PDP-8/Es available [NOT!]))

(32K mainboard > and the Language Card?? Help me out here....) 48KB on the motherboard, and the Language Card or equivalent 16KB RAM card. The canonical configuration is a Language Card in slot 0 with a 16-pin DIP jumper installed between a socket on the card and a the upper-left motherboard RAM socket (the RAM chip gets relocated to the card), but of course there were many compatible memory cards. I don't recall any reason why you couldn't do this on an Apple ][, but I know I did it on a Rev 7 ][+, and a friend had done it on an earlier rev (4?) ][+ that still had the 4K/16K jumper blocks on the motherboard. Obviously they were all set for 16K (as you must have 48KB on the motherboard). -Frank McConnell

Monitor woes

by maxeskin＠hotmail.com

I just acquired a PS/2 Model 25, the one with an integrated monitor and 8086. The reason it was being thrown away was that while it starts up fine, the MCGA monitor eventually becomes tinted red and blurry. If I turn it off and let it sit for a few minutes, then turn it on, it will work fine again. What is the problem? Can I solve it without the risk of shorting capacitors and blowing myself halfway across the room? My understading is that this machine needs no reference disks, but can I use a hard drive > 20MB? It never mentions it on IBM's site. Lastly, does anyone have any of the original stuff for it, ie software, manuals, etc. ______________________________________________________ Get Your Private, Free Email at http://www.hotmail.com

Computers & Lysol

by healyzh＠ix.netcom.com

Don't laugh. I'm getting complaints around here about one of my computers the SMS-1000 (PDP-11/73) smelling of mold and mildew, and have been asked to either remove it, or spray it down with Lysol. How safe is it to spray a computer down with Lysol? Obviously I'd not run it for a while if I do. Zane | Zane H.
