by Jeffrey Brace 08 Oct '24

08 Oct '24

For some reason people were getting confused by another email chain with the previous date. I was advised to repeat that the swap meet is Saturday, Oct. 26, not any other dates. Thanks! Jeff Brace VCF Mid-Atlantic Event Manager

Some notes on Bendix G-15 - See latest video
by Bob Roswell 08 Oct '24

08 Oct '24

David (Usagi Electric) has posted his 12th video on his restoration of our Bendix G-15. The full list of videos is https://www.youtube.com/playlist?list=PLnw98JPyObn3QSIwUz5Iv6NA1x-uGFqAa In the most recent post he gets the unit to boot! Well worth the watch! Henry Harrison (1917-2010) collected 4 Bendix G-15s. His sons lent one of the G-15s to the federation's museum in Wall. The Harrison estate auctioned that unit S/N 3 https://www.rrauction.com/auctions/lot-detail/347709906735051-bendix-g-15-t… The Computer Museum @ System Source purchased the remaining three units #1 Is on display at System Source #2 Is on loan to VC Federation and is on display in the museum at Wall to replace the unit that was auctioned #3 Is on loan to Usagi Electric and is being restored. We have had volunteers scanning led by Rob Kolstad scanning our library of G-15 Documents. The docs are https://rbk.delosent.com/g15doc.html Most of the documentation we have was from a local Baltimore company that was called Greiner Engineering. https://en.wikipedia.org/wiki/J._E._Greiner_Company Greiner Engineering did the design work for many roads and bridges in Maryland. A side note about Greiner Engineering. They had a long history of winning contracts in Maryland by participating in payoff screens involving a the former Baltimore County Executive, then Governor of Maryland, and then US Vice President Spiro T. Agnew. A good summary is in Time Magazine from August 1973 https://content.time.com/time/subscriber/article/0,33009,907711-1,00.html Bob Roswell broswell(a)syssrc.com 410-771-5544 ext 4336 Computer Museum Highlights<http://museum.syssrc.com/> [cid:image001.jpg@01DB18AC.A53F4430]

I donated a pair of Carrier Access ADIT600 channel banks in the factory rack kit to VCF a while back. Anyone know where they are in the warehouse at Camp Evans? Martin

I guess if you can tell us specifically which cards you are interested in using, we might be able to offer better advice. I probably wouldn't think it was worth the effort unless the board performed some specialized function (e.g. control some specialized piece of equipment). I can't imagine any world where it would be worth the headache for something commonplace like an Ethernet card, video card, etc. Devin On Wed, Oct 2, 2024 at 1:35?PM Bill Degnan via vcf-midatlantic <vcf-midatlantic(a)lists.vcfed.org> wrote: > > time-wise, why not just get an IBM XT /clone and use that?

I would point out that the PCI Express standard still maintains the subtractive addressing carve-out and I/O address spaces required for ISA cards, not least because some low-level elements of the PC architecture still use/emulate the old addresses. I believe there should be ISA expansion chassis available using commercially available bridge chips (a lot of PCIe serial cards are also just ISA or LPC (which is kinda-sorta serialized ISA) chips stapled onto a PCIe->ISA bridge chip as well) meant for industrial controls, but be warned that they're generally not cheap. There are also USB bridges, but I assume you'd need to write new drivers because there's no standard for tunneling ISA over USB like there is for PCI/PCIe. This is one such example. https://arstech.com/usb2-products/37-usb2isa-x3.html And it sounds like they also have a compatibility driver layer for it for many legacy operating systems: https://arstech.com/content/35-universal-software-layer For something like RPi or BeagleBone, you'd need to write your own drivers. - Dave ------------------------------ Message: 5 Date: Wed, 2 Oct 2024 18:52:48 -0400 From: Neil Cherry <ncherry(a)linuxha.com> To: vcf-midatlantic <vcf-midatlantic(a)lists.vcfed.org> Cc: David Riley <fraveydank(a)gmail.com>, Jeffrey Jonas <jeffrey.scott.jonas(a)gmail.com> Subject: Re: [vcf-midatlantic] ISA bus via USB?

I personally run little 4-slot industrial ISA backplane systems for ISA cards that support something important in the shop, like one of the EPROM programmers, or the NI GPIB-410 test/debug/sniffer board. You get to choose the CPU board, anything from 386SX to high-end Pentium III are common and available. I can then run whatever OS supports it without any extra work, and the hardware is more reliable than consumer stuff from the era. It's also pretty small! I know that's not a direct answer to the question asked :P Thanks, Jonathan End of vcf-midatlantic Digest, Vol 77, Issue 2 **********************************************
