This is an excellent idea. So far, I only have one interested American, but if others get in touch with me we will try to organize something. Be aware, though, that things will probably take some time. I don't have ready access to the attic in question and before we even start planning I will need to meet and discuss with a few people. /F

BCI-2000 bci2000 Unibus Adapter for the PCI Bus _________________________________________________________________ The BCI-2000 Unibus Adapter enables Unibus devices to be connected to workstations supporting the PCI bus. The BCI-2000 supports both PIO and DMA Unibus data transfers as well as providing support for all four Unibus interrupt levels. The BCI-2000 consists of a single slot PCI controller, a dual-width Unibus cable adapter module, and an eight-foot shielded interconnect cable. The PCI controller occupies a single PCI slot. The Unibus cable adapter installs into the Unibus connectors A and B of an expansion chassis or user's equipment, replacing a Unibus cable. The BCI-2000 provides complete support for: * Unibus PIO data transfers including read word, data-input-pause, write word, and write byte. * Unibus DMA data transfers including read word, write word, and write byte. * All four Unibus interrupt levels: BR4, BR5, BR6, and BR7. _________________________________________________________________ Features Provides a migration path. The BCI-2000 allows users of Unibus systems to migrate to the new high performance PCI workstations and retain their existing Unibus I/O devices without loss of function or performance. High performance. Unibus PIO and DMA data transfers occur at maximum Unibus speeds -- throughput is limited only by the Unibus device. Cost savings. The BCI-2000 provides users the choice of low cost, high performance PCI workstations while retaining their existing investments in Unibus hardware and software. Easy to install. The BCI-2000 allows multiple I/O devices to be connected to a workstation while occupying only a single PCI-slot. Easy to maintain. The BCI-2000 executes a comprehensive set of diagnostics to automatically verify module operation. _________________________________________________________________ Description PIO Transfers The BCI-2000 supports the four types of Unibus PIO data transfers including read word, data-input-pause, write word, and write byte. The entire Unibus address space is available for access by a PCI host. DMA Transfers The BCI-2000 provides full compatibility with the three types of Unibus DMA data transfers, including word read, write word and, write byte. Single and multiple data transfers are supported. Interrupts The BCI-2000 passes Unibus interrupts to the host for service if interrupts are enabled by the host and the interrupts are higher priority than the priority established under software control. The BCI-2000 stores the 8-bit interrupt vector in an internal register that is referenced by the host to determine the interrupt service requested. Unibus Termination The BCI-2000 provides Unibus termination for one end of the Unibus. The user must ensure the Unibus is terminated at the end of the Unibus within the expansion chassis or the user's equipment. Unibus Parity Unibus parity signals PA and PB are terminated but otherwise not supported by the BCI-2000. _________________________________________________________________ Software Compatibility The BCI-2000 is not supported under existing OpenVMS, Ultrix, or OSF/1 operating system software and requires software drivers to support the features offered bu the BCI-2000.

Altair scans update

by rcini＠classic.msn.com

For those who have asked... The Altair scans are ready to post, I just have to ZIP them up and send the tape to Bill Whitson. Does anyone have his physical address?? ------------------------------------------------- Rich Cini/WUGNET <rcini(a)msn.com> - ClubWin Charter Member (6) - MCP Windows 95/Netowrking

Computers (fwd)

by manney＠nwohio.com

> I also have windows3.0 which will run on a 640k > xt! > > Allison Hmm...I've got Windows /386 ("Part of the upgrade path to OS/2", the package proudly announces.) Ever played with Geoworks? That would run on an XT, and very nicely, too. Had several improvements over Windows, including "sticky" menus which could be detached and moved. *Very* nice drawing program -- much better than Paintbrush. I liked it better than Windows. Manney p.s. dug up 3 sealed, boxed sets of OS/2 2.1 (not over 10 yrs old...sorry). Anyone interested?

Half an attic full of old computers (help save them!)

by ekman＠lysator.liu.se

Hello! I am currently working for a company in Gothenburg, Sweden that used to be the Scandinavian importer for Sord computers (a Japanese company) during the eighties. Their attic is full of old stuff, most of which the boss would like to throw out, and which he would unless a couple of employees disagree with him. Not only are there computers and peripherals, but also loads of documentation and software. I had a discussion with the boss recently and asked if it would be possible to ship the stuff to interested parties if I would do the work free of charge. No such luck. I may be able to persuade them to let the stuff for free if the receiver pays shipping, however. But shipping from Sweden is expensive. Thus, I am now trying to see if there is any interest in having any of this for the cost of shipping. If there is, I will try to make a definite deal with the company and then make a list of what is available. I am afraid that if nothing is done soon everything will be dumped into a container. If you are potentially interested, please reply directly to me (ekman(a)lysator.liu.se). If you have any questions about Sord computers in general, reply to the mailing list. /F PS. There will be no IS-11 or M-5 stuff (I will be reserving anything such for myself) but probably several M-23 and M-243 and who knows what else. Possibly also hand-held GRiD terminals and maybe the odd PC compatible. I know there are some UNIX minis, but the company may want to keep these since they still have customers using such. Everything will be adapted for Swedish electricity net (220 V).

Honeywell "Black Apple" floppy drives

by kaikal＠MICROSOFT.com

I almost forgot - in addition to my earlier trade list post, I recently acquired four (4) Honeywell "Black Apple" Disk II floppy drives. These are up for trade. Kai (BTW, no, I'm not selling any of this stuff, send trade lists instead of offers to buy! Maybe I'll be interested in something that isn't on my want list)

PDP-11/44 is Finally Up!

by dseagrav＠bsdserver.tek-star.net

It works. But I shouldv'e noticed no termination right off... That was a stupid mistake. Anyway, now that it's up, I get to find a more permanent home for it- This building goes away at the end of the month! We're looking at Jeff's garage. I was telnetted into it last night. Once I figure out how, it goes up for public access. Anyone know of PPP for RSTS/E? :) Or I could always re-write the TCP/IP protocol in BASIC-PLUS... Oh, and we're going to take it apart to move it this time. Give Jeff more opportunity to bust the OTHER foot... And less work for me! How much does a DEC cabinet weigh empty?
