Modifying microcode

by kylevowen＠gmail.com

Has anyone attempted to reassemble and update the microcode on a MicroVAX? Seems like there's enough stuff here to possibly do it: http://simh.trailing-edge.com/semi/ucode/ I'm thinking about trying to find a microcoded architecture to play with before I design something around the Intel 3000 series. I've got a MicroVAX 3800, so I suppose I could run MICRO2 to assemble the aforementioned microcode. But then what? I assume PALs would have to be burned to implement the new microcode. Or is it more complicated than that? I don't have a PDP-11/60, unfortunately. I do have an 11/45, though...so with this modification, I suppose one could have some fun: http://repository.cmu.edu/cgi/viewcontent.cgi?article=3241&context=compsci Thanks, Kyle

eBay search fail

by jnc＠mercury.lcs.mit.edu

So someone mentioned this to me: https://www.ebay.com/itm/222941705847 Now, the crazy thing is that I religously do a search for "PDP-11" for newly listed items on eBait at least once a day - and this never showed up! I just did a search for sold "PDP-11" items, and it's not showing up there either - although a search for sold "PDP-11 parts" turns it up! Anyone have any idea why it didn't turn up? That is a regular '-', not an mdash or anything, and those are 1's, not lower-case l's. And it does show up in the search for "PDP-11 parts". So I can only conclude that somehow eBait's search function blew out somehow? Anyway, someone got a total steal: at least _3_ H960's, a TU10, and an -11/45 (can't tell if there's an FP11) - and who knows what else is hidden! Noel

Announcement: VCF Midwest 13!

by silent700＠gmail.com

Summer is almost here and that means it's time to get it in gear and start planning our next Vintage Computer Festival Midwest. Astute readers will note that this announcement comes many weeks later than in past years, but rest assured there is still plenty of time remaining to make your travel plans, reserve a table or get yourself into the mood for a full weekend of classic computing fun. Here are the necessaries: What: The Thirteenth Vintage Computer Festival Midwest When: September 15-16, 2018 (note that that's one weekend later than the usual dates!) Where: The Holiday Inn Elk Grove Village, Elk Grove Village, Illinois - about 30 minutes west of Chicago with a free shuttle bus from ORD! URL: http://vcfmw.org More info for the uninitiated and VCFMW veterans alike: - We do not charge admission. Thus, we are a community-supported show, so we humbly beg your kind donations, which can be made via two different links at vcfmw.org, or at the show. - Always an entertaining spectacle, there will once again be an auction! This is the other way we fund the show, so your donation of old computers (or anything even marginally related) is greatly appreciated. If it's a little too nice to put in the Free Pile, please consider donating it as an auction item. - Typical show hours are 9am Saturday 'til late night, and then 9am-4pm on Sunday (clean-up begins around 3pm). Early load-in is usually available on Friday afternoon, hours at the hotel's discretion. - The show really begins on Friday night, at least for exhibitors. We typically go for an informal group dinner and return to the hotel to complete setup. Don't worry if you're getting into town late, you can still set up Friday night (until 11pm or so). If you're arriving Saturday morning, your table will still be reserved. - Tables fill up quickly! If you'd like to exhibit, please fill out the table reservation form at http://vcfmw.org/signup.html. If the form is closed, it's because the buffer filled up and we're still processing requests. We don't want to reserve space we don't have! - Hotel rooms at the Holiday Inn are available at the group rate of $92/night via the link at vcfmw.org, or by calling the hotel at the number listed on our site. If the online room block is full, please try calling the hotel directly. - There is an on-site restaurant in the hotel that serves breakfast through dinner and a bar that is open late-ish. Consensus seems to be that they have good food and not having to leave the hotel to eat is a big plus. Feel free to forward this email or post its contents to your favorite forum. We'll see you in September! -j Twitter: https://twitter.com/vcfmidwest Facebook: https://www.facebook.com/events/248644859019545

Apple (Lisa 2/10) MAC XL UNIX 5

by billdegnan＠gmail.com

I have a diskette labeled UNIX SYSTEM V VPI UNIX disk 'A' (vpi)* 8/85 UniPress Software, Inc. I have the small installation manual that talks about inserting the disk to serialize it, and how to install UNIX onto the Lisa 2/10 in Mac XL Mode. It is a small implementation of AT&T UNIX V. The disk is bad. Anyone have a process for recovering or reading an Apple Mac XL disk? This seems like a piece of software that should be preserved, as a curiosity. Does anyone actually have a working copy of UniPress Software UNIX for the Lisa XL? Bill

CDC 9762 drive, alignment disk and exerciser on Ebay.

by mattislind＠gmail.com

Someone is selling a drive that was just taken out of service ! And alignment disks and exercisers for CDC 9762 (it doesn't look like a 9766 / RM05 even though it says so in the listing) Probably useful to RM02 or RM03 owners as well. https://www.ebay.de/sch/rbembenek1/m.html?item=142830473695&rt=nc&_trksid=p…

pdp8e rack header wanted (will trade for PDP 11 header)

by billdegnan＠gmail.com

Anyone want to trade a pdp8e rack header for a PDP 11 (pink/red) header? Does not have to be perfect. I am located in Landenberg, PA USA. I have other DEC rack-related parts to trade for this if that's not what you want. b
