XyWrite's history of commercial development took a few odd turns, and suffered the consequences of some marketing mishaps.

Looking for new maintainer for DECVAX.ORG and PDP11.ORG

by mrbill＠mrbill.net

Hey, everyone. I resubscribed to cctalk tonight. I'm way too swamped lately (in fact, for the past year or two) to adequately maintain the PDP11.ORG and DECVAX.ORG domain(s) and web sites. I'm looking for someone, fairly involved with the community, who would like to take over ownership of the domains, web sites, etc. I can keep hosting the DNS (if you wish), or provide secondary/backup DNS if needed. I just don't have the time to work on them anymore, and have moved away from older DEC stuff. My only "requirement" is that whomever takes over this project (whether it be one person, or two people; one for VAX and one for PDP) is that you put some effort into it, that you be knowledgeable about the subject matter, and that you don't just let the sites languish. Getting reimbursed for the $30 I've spent on renewing the domains this year would be nice, but not required. 8-) I've also got about a truck-full (maybe a station wagon load, maybe less) of old DEC documentation, handbooks, software on paper tape, a disc pack or two... Jeff Sharp has seen my garage. 8-) I can't ship any of it (unless you provide a FedEx or UPS account number to bill to), and would like to avoid throwing it in the trash. At least 3-4 "storage tubs" of manuals and documentation, a mixed VMS 4/5 "orange wall", and various other things. If you're interested, please contact me by email. I don't have time for DEC/PDP stuff anymore, and need the space in my garage back - but want it all to go to someone worthwhile. Bill -- bill bradford mrbill(a)mrbill.net austin, texas

New Finds: SWTPC :-)

by rigdonj＠cfl.rr.com

A friend of mine picked up about 30 boxs of electronics parts, data books, evaluation kits, parts samples, etc at a local flea market last week. Today I was helping him go through the stuff and I spotted some familar looking boards. I picked one up and remarked that it looked like something for the SWTPCs. Then THE very next board that I picked up was marked "SWTPC" so I knew I was onto somehting good. I dug through the boxs and got 6+ boxs of disks with software for the FLEX OS (used on the SWTPCs) and found six circuit boards for the SWTPCs. Here's the list: (1) SWTPC MP-09 - Replacement CPU board for the SWTPC computers, uses 6809 CPU. This is a MP-09, not an A or B. (2) A Southeastern Micro Systems DDC-16 Floppy Drive Controller. (3) A Tanner Computers SS-50 64k memory board, uses 2716 EPROMs or 6116 S RAMs. This one has the S RAMS installed. (4) A SWTPC MP-R 2716 EPROM burner card. (5) A SWTPC MP-T Interrupt Timer board. It's implemented with a 5009 programmable counter/ divider and 6820 PIA ICs and provides software selectable interrupts of 1 usec, 10 usec, 100 usec, 1 msec, 10 msec, 20 msec, 100 msec, 1 sec, 10 sec, 100 sec, 1 min, 10 min or 1 hour. (6) A Gimix 2 port Serial Interface board. Fits the SS-30 socket and uses two MC68B50s. I found everything else described on Michal Holley's SWTPC site but not this one. Does anyone have any details on it? Pretty good haul, specailly considering that I didn't have to go anywhere and find it :-) Joe

I am pleased to be able to say that I no longer remember the details, but the problem was something like that the card had enough room in its buffer to hold no more than one received packet. If you sent it another one before the processor on its end got around to reading the packet out of it, one packet or the other got dropped (I'm thinking the one in the buffer got dropped so that the new one could be buffered). If you didn't want any packets to get dropped, you needed to be careful to not overrun the buffer by having more than one packet outstanding. Keep in mind that this was 1987 or so and PC clock speeds were right around Ethernet bus speed, so the PC couldn't get the packets out of the buffer as quickly as the network could put them there. If someone else out there remembers more, please do feel free to jump in. -Frank McConnell

American Automation EZ-Pro development system

by arlen＠acm.org

This microprocessor development system dating from the early 80s includes a hardware in-circuit emulator for the Motorola 68HC11. I'd like to get it running but I have no documents or software. Can anyone help? The main box is model number AA-547 and I believe it hooks up by serial cable to a host PC. Besides the external ICE hardware, there's also a small prom programmer box hanging off the system. Thanks in advance, Arlen Michaels

Wanted: RL02 Working...

by cvendel＠att.net

Hi everyone, I found a place on the East Coast selling RL02's and RLV12's for $120, anyone in the NJ/NY/CT/MA/RI area (basically anyone in like a 3hr driving radius of me) have an RL02 they want to sell cheap??? I'd like to pick the unit up and save myself the $100 shipping charge (plus the worries of it bouncing around in the back of a UPS or Fedex Ground truck!) So I'd be willing to pay someone in my area $100 for a drive and $20 for an RLV12 if you have them and they are known working, please let me know, thanks!!! Also I'm still looking for an RM05 or CDC9976 300MB Disk Pak drive, if someone in my area has one that I could take on loan for 1 week and return for a $$$ Rental Fee, I'd be willing to work something out with them. Thanks, Curt

Older wordprocessing software

by evan＠flextech.net

Jules, I still have most of those old versions of WordPerfect 5.1 DOS, WordPerfect 6.0 for both DOS and Windows (the file formats are identical, BTW), MS Office 4.3 for Win3x, AmiPro/Samna, and even (gasp) MultiMate. I have *several* copies of the WordPerfect 5.1 manuals, along with some old Lotus 1-2-3 v2.3 and Harvard Graphics manuals (and the software for those also). Personally, I was a WordPerfect aficionado (because of the DOS/WIN file format matching). Hated Word, and used AmiPro/Samna for legal documents (best on the planet back then). Most are on 5-1/4", a few are on 3-1/2", and Office is on CD. Let me know privately what you need and we'll work out a way to get it to you. Evan Pauley ---------- You wrote: Hi all, perhaps pusing the boundaries of off-topicness here a little, but... I'm taking suggestions for wordprocessing software to run on an older 486 laptop (1994, so almost within the 10 year limit!) that's running Windows 3.11 ... I still use the machine for a bit of wordprocessing ocassionally (such as it is with Windows Write), and better software would be nice. The laptop's handy for taking stuff down on before formatting things 'properly' on a more modern desktop. I remember Ami Pro being quite reasonable on a similar spec desktop machine, but my copy went to tape years ago and around half of the old tapes of mine that I found recently are no longer readable :-( Suggestions of alternative software welcome though... cheers Jules

OS uptimes

Somehow an embeded box that doesn't have to run arbitrary and buggy programs seems like cheating! Here's the uptime on a old VAXstation just before a scheduled power outage: $ sho sys VAX/VMS V6.1 on node BUMMER 10-MAY-2002 16:02:42.38 Uptime 1099 02:42:54 1099 days. Admittedly it spends most of it's time sitting quietly in a corner. Looking at: http://uptime.netcraft.com/up/today/top.avg.html The top 3 current entries appear to show 1500+ The top is 1751 on a BSD/OS system. The FAQ indicates they can't detect more than 497 days of uptime on some operating systems. Another site is: http://www.uptimes.nu/index.php?area=statistics But the highest uptime is suspect: "31y 335d 20h 15m (FreeBSD 4.8-RC)" since FreeBSD 4.8 came out within the last year! -phil

SCSI bit-banging

by emu＠ecubics.com

Hi all, I guess we all remember this boards attached to ataris/commodores/apples, where we had a PIA/parallel port to attach some of the nice SCSI disks. However, I don't find anything about this old bit-banging interfaces on the net. Any links ? cheers

Kinda OT: DEC 3000 Model 300 AXP Memory

by zmerch＠30below.com

I don't think this machine is *quite* 10 years old yet, but it's pretty close -- and it's 'different' enough that hopefully I won't get flamed... I have a DEC 3000 Model 300 AXP which is currently sitting idle -- it has Tru64 Unix 5.0 on it currently, and 64Meg of RAM. I was thinking of putting Alpha VMS 7.1 instead, for to start learning VMS again (someday... :-O ) and I recall saying that Alpha VMS is much happier in more than 64M Ram, so I was thinking of upgrading it. I do know that it uses 'standard' 72-pin Parity FPM Memory - but what I don't know is: how finicky is the machine? Will just any Parity memory work, or is it limited to certain manufacturers? I have a supplier that has used 32M Parity 72-pin FPM memory for $6/stick -- a decent price comparatively - I've seen it at $30+ per stick, which would make a memory upgrade cost more than the machine itself... I have no idea what they have for manufacturers of the memory - these guys prolly don't, either. It's a reputable company (I've ordered from them before) but they don't get too deep with the specifics. (WRT another OT thread: They have 3Com 905C-TX NICS for $10 each...) Should I take the chance and order the memory, or would it be foolhardy to do so? Thanks, Roger "Merch" Merchberger
