Announcement: CP/M Programming workshop,Sat.Apr.10.2010,12pm-7pm, Delaware Hackerspace

by ragooman＠comcast.net

Announcement: CP/M Programming workshop For the vintage computer enthusiasts, in conjunction with the MARCH Computer Museum and the Delaware Hackerspace group, we like to invite you to a new workshop this year involving vintage computers. This new workshop is about CP/M programming and it will teach you how to install, build and configure CP/M on your vintage S-100 computer system. All the necessary steps are shown during the lecture and afterward is a hands-on training session which will let you upgrade your S-100 computer with a floppy disk based system and CP/M. Instruction and lecture will be provided by Rich Cini of the Altair32 emulator project. Please look at the link below about the workshop checklist for a detailed list of requirements about this workshop. You'll need to know what to prepare beforehand to get ready for this workshop. Ask any questions you have about getting ready before the start of the workshop. A knowledge of assembly programming, S-100 hardware, and CP/M operation is required for this workshop. Please do not come unprepared. We currently have seats for 12 workbenches for those who want the hands-on training. An additional 10 seats are available for those who like to watch and learn. If we happen to get more requests for this workshop, we will try to accommodate as many people as possible. This is a first come, first serve event, sorry, but we cannot accommodate latecomers. Once the registration opens, please specify which seat you like to reserve. The workshop is located very close to I-95 for those that are driving. More information can be found at the Delaware Hackerspace website below.

Qbus SCSI host adapters [was: Re: Collections, was: Be careful handling computer racks]

There are a couple of CQD-423/TM on eBay now that have been there for a while. Well under $1000, but more than most people would pay. I think it was a list member that recently sold a CQD-220/TM for around $100 on eBay. A couple of months ago I got a CQD-223/T off of eBay for around $60, which I then turned into a CQD-223/TM. An AVIV QSA S-box handle disk/tape SCSI adapter just went for $70 on eBay. Maybe the S-box handle adapters are less valuable to most people as they cannot be directly installed in a BA23 or similar without modification. -Glen

Lack of Posts on alt.sys.pdp11 and vmsnet.pdp-11

by jhfinedp3k＠compsys.to

I normally watch theses two newsgroups. However, the last post on vmsnet.pdp-11 seems to have been on September 27th, 2009. Even for this low frequency group, that seems like a long time. For alt.sys.pdp11, the last post was on January 4th, 2010. Since there is usually a post every few days, this is also a long time. Has anyone seen any more recent posts? Perhaps the newsgroups server I use is not passing the posts along. Sincerely yours, Jerome Fine

Z80 CP/M and 6809 CUBIX homebrew computer

by lynchaj＠yahoo.com

Hi! One of the N8VEM builders just posted this photo of a completed N8VEM homebrew computer system. http://n8vem-sbc.pbworks.com/f/n8vem_case_nb.JPG The homebrew computer is functionally complete with all the components you would expect of a system of the late 1970's early 1980's era. It runs CP/M on the Z80 and CUBIX on the 6809. All information for hardware and software design is free and publicly posted on the N8VEM wiki and mailing list. You are welcome to join if you would like. You can make your own or buy low cost PCBs and build your own system. Andrew Lynch

But it is a problem; everybody moans when a collectible gets scrapped, but when it comes to actually spending the time and/or money to save it there's often a deafening silence... mike (also in Toronto but with no space or interest).

Don Maslin (was Re: Collections, was: Be careful handling computer racks)

by vern4wright＠yahoo.com

Al, The short (or long) of it is that 1) I got everyone to stop calling Don's wife Winnie right after his death (8-2004) with the understanding that I would rescue his archive, package it, and make it available for everyone to download gratis (the Computer Museum here in SD was going to provide a platform and a bit of legal protection). 2) Winnie later declined to allow anyone to find, rescue the archive. There was no way to make her understand WHAT the archive was, much less its value. IMHO, she thought Don was just puttering in the garage that served as his shop. When it became clear that she would not keep her side of our agreement, and that my involvement was not going to be helpful, I suggested that Jay West contact her (I don't think he did). 3) A family member (who gave me the photos of Don and Winnie I sent to Sellam for the following VCF) told me that he thought the garage would remain as it was until Winnie died, or had it cleaned out by some junk hauler. I later heard that a lawyer was going to find the archive and rescue it; he supposedly thought it could be done in an afternoon. Rots of ruck, I thought. Don's shop was a physical mess, and the archive was not in just one computer, all nicely organized. Personally, I felt - and still feel sick about it. I OUGHT to have somehow forced Don to put the stuff on CD (I showed him how, but he hated Windoze with a passion and wouldn't play Linux either.) And he was an adult.... You can get all the details in the 2004-2005 ClassicCmp archives. Or write me back.

Fwd: Another possible round of partial SBC6120 & FP6120 Kits!

by sethm＠loomcom.com

Hey folks, I'm forwarding this message from the Spartime Gizmos mailing list because I think there may be some interest here. Steve Gibson is trying to assess interest in doing another run of Sparetime Gizmos' PDP-8 clone, the SBC6120. This is a big job. The kit would include all the custom parts for both the SBC6120 single board computer and the (excellent, IMHO) FP6120 front panel kit. If you missed out on the last round of this kit, now would be a very good time to express interest in getting another run done. Read the message below for details and the URL where you can register. -Seth -------- Original Message -------- Subject: [sparetimegizmos] Another possible round of partial SBC6120 & FP6120 Kits! Date: Wed, 13 Jan 2010 14:23:02 -0800 From: Steve Gibson <sparetimegizmos at grc.com> Reply-To: sparetimegizmos at yahoogroups.com To: sparetimegizmos at yahoogroups.com References: <hih47u+3ash at eGroups.com> <hijlf8+hva1 at eGroups.com> Everyone... I have been coordinating with Bob Armstrong about the possibility of another round of combined SBC6120/FP6120 kits. If sufficient interest can be generated -- at least 50 purchasers -- Bob has agreed to produce another round of kits containing all of the special, custom & programmed bits required to assemble the combination of an SBC6120 and FP6120. My web site's tribute to the PDP-8 consists of eight pages, the last one of which explains the details of the kits and provides a web-form for allowing interested people to declare their interest. A few minutes ago I announced the existence of the kits during my weekly Security Now podcast recording. The podcast goes live tomorrow (Thursday), when we'll have an audience of about 80,000. But a few thousand listeners watch the recording live ... and we immediately received several declarations of interest. If anyone here in this group was wishing they were able to obtain additional kit(s), I'm quite hopeful that there might be enough interest remaining for us to squeeze out another round. Here's the page... http://www.grc.com/pdp-8/yourown-sbc.htm And if by some chance you are not familiar with these terrific kits, other pages in that area, linked at the bottom of that page, contain videos to give you a good idea of the final product. :) Steve Gibson.
