Don't panic! Our web site is down (and may be up-and-down again) for maintenance this afternoon. Someone on Facebook asked if we're replacing the vacuum tubes. :) ________________________________ Evan Koblentz, director Vintage Computer Federation a 501(c)3 educational non-profit evan(a)vcfed.org (646) 546-9999 www.vcfed.org facebook.com/vcfederation twitter.com/vcfederation

SPITBOL Manual Scan
by william degnan 16 Feb '17

16 Feb '17

For those of you who wanted a copy of Bill Dudley's SPITBOL 2.0 manual that he gave me at the workshop this past weekend, I found a copy here. His copy starts at page 7 of the document: http://www.snobol4.com/spitbol360/spitbol_360_manual.pdf Note this is an IBM OS/360 implementation of SNOBOL-4 computer language for IBM 360 and 370's. SPITBOL is smaller. I posted a few photos from the workshop on my site, nothing exciting. Bill

Well, the DS12887A has worked well for *all* of my VAX and or Alpha systems that were equipped with the DS1287A. That "slicing into the chip" hack to add a battery has seen serveral re-incarnations over the years whenever the topic of replacement arises.

There is a literal "mod" of Dallas chips: http://www.retrotechnology.com/herbs_stuff/sgi_battery.html wherein you slice into the epoxy package and splice in a watch battery. if this is the mod you are doing, I'd be glad to reference any Web page you have about doing it. There are likely some old versions of the Dallas time-of-day chip and RAM which have no modern version. That said: VAXman posted: > The DS1287A was fairly common TOY clock back then.

OT: Windows Resource Kits available
by Kelly Leavitt 16 Feb '17

16 Feb '17

At least the manuals. One Windows NT, one Windows 2000 server. I believe the CD is there for the 2000 server. Anyone want them? Can bring to VCF or you come get them. Will not ship because I'm lazy and they are heavy/bulky. Thanks, Kelly
