OT: Dell Dimension XPS 466V

> Working on a Dell 486 computer. I need a RTClock battery, but otherwise > it's running quite nicely Windows for Workgroups 3.11 The question of batteries is on-topic IMHO. Batteries in the long term, cause corrosion of parts that have constant current on them. This is true all the way back to 128K Macs. also, many batteries leak (not coin cells), that's not good either. If you add a battery pack, make sure you can readily pull it out when the computer is in long-term storage. Windows for Workgroups (Win 3.1 + networking) is worth preserving. It's a legacy OS now. It ran for many years in embedded applications (back ATMs) and Microsoft support only ended several years ago. Many consider Win 3.1 the first really "successful" M/S Windows OS product. If I had time and interest, I'd see about migrating Win 3.1 to the Heath-Zenith Z-100. That's a S-100 system that is somewhat IBM PC compatible. I don't recall if Windows was offered for that platform, later Zenith PC's ran even earlier Windows (I have those distributions). Herb -- Herbert R.

Please contact me if you would like additional info or to make an offer on any item. I wont bring this stuff unless someone wants it. I would prefer not to ship these items if I can avoid it so the workshop attendees are going to get the 1st shot.

FS: Cromemco PRI S100 Printer Interface NIB + Manual

Link: http://www.ebay.com/itm/272110179325 Untested as I didn't want to unwrap it. This looks like it has never been used at all, still in its styrofoam sheet with plastic overwrap. The original manual and a 25-pin breakout cable were in the box with it, so I suspect it's the original box. Thanks, Jonathan

Snow and January 23/24 workshop
by Jeffrey Brace 18 Jan '16

18 Jan '16

Currently the 5 day forecast for this area says 1-3 inches of snow for Friday night for the InfoAge area. Not a lot and plenty of time for salting/cleaning of major highways. When we get within 48 hours, that is when we get the most accurate forecast. Anyway, I will be keeping a close watch at the weather and be making a decision by Friday morning as to whether or not to postpone the start of the workshop.

Friday classes @ VCF East
by Evan Koblentz 18 Jan '16

18 Jan '16

Very few people responded to last week's call for subjects/teachers, so we're taking a straightforward path instead of creative new things. Most classes will be two hours. Some may be double sessions; TBD. We don't yet know if there will be three or four classrooms available. Hoping to find out soon. There will be morning and afternoon sessions, meaning 12 or 16 classes. Tentative topic list follows. These are all tech repair classes, not historical lectures. 1. Apple 1 + Replicas 2. Apple II 3. Apple Classic Mac 4. ASR-33 Teletype 5. Commodore PET 6. Commodore 64 7. DEC PDP-11 8. IBM PC 5150 9. MITS Altair 8800 10. Radio Shack TRS-80 11. Cassette Tape - Willegal 12. PCB Design for Vintage Computing - Willegal If we have a fourth room available: 13. Power Supplies 14. CRT 15. Paper Tape (should immediately follow Teleype on the schedule) 16. Disk Imaging + Drives Topics can change based on who's available to teach, demand for other subjects/systems, etc.; meanwhile I'll contact several list members individually to get the necessary teachers (or feel free to volunteer). Some subjects are repeats from past years.

Re: [vcf-midatlantic] Infoage outside ramp doors

What prompted my message is we often > see doors LEFT propped open when people are taking their > leisurely time moving stuff or just forgotten about. OK, this conversation is taking a sour turn. I don't like descriptions like "lazy" or "leisurely" about the difficult efforts to move stuff in, out and around InfoAge. I've moved stuff there myself, it's not easy - others have moved much MUCH harder stuff. I think there's a confusion, between two sorts of access. One is, moving stuff in and out, and propping doors wide open to do so. Certainly, for fire-code and energy reasons, they should not be left that way. This seems to be what Evan has in mind. But the other, is propping doors open for (re)entrance, enough to keep them from jamming closed, or from locking from outside. For example - during the Festivus, I recall the outside doors to the grill, HAD to be kept from closing with a "prop". Otherwise, I could not get back in! Did they lock, jam or both? Sorry, I wasn't paying close attention and don't remember now. And I already mentioned the iMac "prop" in common use for years at InfoAge. So my point was/is - if the doors can't be opened from the outside, that might explain why they are left "wide open". It's not merely about convenience or interpreted as "laziness". It's about getting back in. I agree with Evan, this is not only a VCFed issue, InfoAge is responsible for maintenance of doors. Maybe VCFed can contribute to the InfoAge repair with Evan's attention and funds. Dollars spent on the doors, might save InfoAge heating costs which Evan pointed out were "huge". As for "out of VCF's scope": I dunno, we use the doors, right? VCFed properties (and mine as an exhibitor) are under InfoAge locks and keys, right? And Evan brought it up, before our next event. And April's VCF-East is coming up too, even more movement then. The problem seems to be, then, some combination of InfoAge door maintenance and repair; and some rules-of-access for moving items in and out of InfoAge. A block of wood on a chain, as a handy prop, may immediately solve the "wide open" problem. It won't fix a broken door, but it may help some people change their behavior, while the door is under improvement. I'm sure the VCFed people who have moved items, can describe their experiences upon request. And the doors, they either work or they don't, and can be examined by Evan and staff. I think further discussion should be private, as Evan works the issues, and as he's has now put the word out about a now-specific behavior. A discussion about a specific person's behavior, or their complaints about doors, should be private. And it's an InfoAge maintenance issue (which impacts VCFed). I have nothing further to add, in any event. Herb Johnson -- Herbert R. Johnson, New Jersey USA http://www.retrotechnology.com OR .net
