http://bert.brothom.nl/gallery2/main.php?g2_itemId=3226 Is it worth anything? Wanna have it? Let me know. I bought it at an auction but I was disappointed to find just relays inside. It takes up a lot of space, so I want to get rid of it.

IMP system software

by sethm＠loomcom.com

I think I asked about this several years ago, but I thought I might try my luck again. Is anyone aware of any surviving ARPAnet IMP System Software, in any form? -Seth

N8VEM S-100 Prototyping Board PCB manufacturing order imminent

by lynchaj＠yahoo.com

Hi! If you are interested in getting one or more N8VEM S-100 Prototyping Board PCBs, I am getting ready to make a manufacturing order. Based on my current projections, I am estimating a single N8VEM S-100 Prototyping Board PCB will cost $18 each (reduced from $25 each originally) plus $3 shipping in the US and $6 shipping overseas. I will combine shipping to reduce shipping costs depending on final weight. Please let me know soon if you would like to join in the order. If more persons join the order PCB costs may be further reduced. You can see additional information on the N8VEM S-100 Prototyping Board at the N8VEM wiki: http://n8vem-sbc.pbworks.com/browse/#view=ViewFolder <http://n8vem-sbc.pbworks.com/browse/#view=ViewFolder&param=S100> &param=S100 Thanks and have a nice day!

8MM Tape drives

by teoz＠neo.rr.com

I hit the local recycler today and purchased a few tapes drives. Snagged a DDS3 external, DDS4 external, and a cool looking IBM drive that I was hoping might have been AIX. Turns out its an 8MM Mammoth 20/40GB drive (looks like ebay #290335147769). The drive had a couple AS/400 stickers on it and appears to be HVD (with terminator attached on the back). Are these drives pretty decent, reliable, and fast? I don't have any experience with them and grabbed it because I like collecting any kind of removable media drive I don't have. Turned it on (fan must be moving quite a bit of air by the sound of it) and the LCD went through diagnostics and then to a ready state with no tape so I assume its not DOA so far. Just curious what you guys think before I go looking for tapes and a cable to connect it to a HVD 68 pin card in my SUN U5. I assume Solaris 8 might know what to do with this thing, or PC backup software will work with it.

For an identification like that and possibly to find someone else with the same accelerator who can ID the missing parts, I'd try the appropriate sub-forum over on 68kmla.net. That's 68K Macintosh Liberation Army. Jeff Walther

RK11-D controller spares available?

by hachti＠hachti.de

Hi folks, does anybody have a spare M7256 board for the RK11-D controller? And/or a backplane for it? If I find both, I'll have a complete controller... Best wishes, Philipp -- http://www.hachti.de

PDP 14

by tshoppa＠wmata.com

> Does anyone have a PDP 14? Or has anyone ever seen one out in the "wild"? > If so, please contact me directly ;) The PDP-14 was not a conventional computer... it was what we call today a PLC (programmable logic controller). Very adaptable to ladder logic and a bit more. DEC was pretty swift in how they allowed the PDP-14 to be configured via a real computer (a -11 or -8). It wasn't the GUI of PLC configuration today or even of the 80's, but it was a good start. The overall model of PLC configured or monitored by a computer still holds true today, I think that DEC could have really taken this idea and run with it but the overlap between industrial control and computers even today is less than thorough. The computer geeks don't understand the industrial control and process engineers for the most part (thus the common misuse of Windows PC's where a PLC could do the job far better and without point-and-drool.) IMHO if you are interested in PDP-14 you must also be interested in early Modicon PLC's, which were far more common, predate the PDP-14, used core memory like the PDP-14, and which the PDP-14 was pretty much a clone of. I think Modicon was also a Massachusets company like DEC. I never used a PDP-14 but I always understood them to be very much like the core-based Modicons I used. Tim.

Help identifying unknown Mac SE accelerator

by derschjo＠mail.msu.edu

Scrounged a Mac SE motherboard+accelerator from a parts bin at RE-PC this afternoon and I'm trying to figure out what it is. Unfortunately it looks like a few parts have been scavenged (a crystal oscillator and a few chips, plus the 68030+FPU) and there's a loose wire on the underside. I can't find any markings that give away its identity. I have a few pictures up at http://yahozna.dyndns.org/scratch/mysterymac/. Anyone have any ideas? Thanks, Josh
