Workshop (@kennettclassic) this Saturday 11/30
by Bill Degnan 26 Nov '19

26 Nov '19

First of all Karen and I just wanted to say thanks to everyone who has visited so far. We have had Mike Tomczak, former Commodore VP and author of Home Computer Wars, Evan, Tony, Dean and his son, Alex Bodnar, Bob Roswell, and a lot of locals new to the hobby, and family. We're going to hold over the Commodore History exhibit for a little while longer, until we replace it early in 2020 During Evan's visit we spoke about coordinating our event dates so that there is no overlap, and we will cross promote our events. I set up a meetup.com group that people can signup with for contact about events or you can friend "kennett classic" on facebook, or just visit the kennettclassic.com website regularly. https://www.meetup.com/Kennett-Classic/ https://www.facebook.com/kennettclassiccomp https://www.kennettclassic.com <https://www.facebook.com/kennettclassiccomp> The first workshop is this Saturday and we had two more workshops planned that hopefully don't overlap with anything VCFed is doing. Moving forward we'll intentionally stagger the workshops. Here is the meetup link that provides the details (it's brand-new meetup.com group so don't be shy to at least join the group) https://www.meetup.com/Kennett-Classic/events/266446596/ Same deal as any workshop I have run at my home or the old office in Wilmington since 2005. Clean and triage your hardware before you bring it, bring an extension cord and power strip, bring tools and parts. If you let us know what you're bringing, it helps others plan what they'll bring and to work together on the same types of hardware. For example, pick a theme like "6502 systems" "S-100 bus" "teletypes" etc. Reminds me of when Dan Roganti came to my house to stay over the weekend for workshop, once with his daughters. Dan was a regular at every workshop back in the day. vintagecomputer.net is full of photos (search term workshop) of past workshops from MARCH and VCFed. Directions and Contact: https://www.kennettclassic.com/contact/ For Sale: https://www.kennettclassic.com/hobbyist-shop/ Kennett Square is centrally located south of Phila and north of Baltimore off RTE 1 between Longwood Gardens and Newark Delaware. This is a very nice retail space with restaurants, pubs, hotels, music, other museums and galleries so if you bring the family and they're not really into vintage computers there will be other things to do. See you there! Future events: https://www.kennettclassic.com/calendar/ Bill

Three high interest visitors today. One visitor spent about 2 hours in the museum. He thinks that he replaced Tom Kirk after he left the company that he worked for. He also said that he worked for the company that made the Xitan. Lots of interesting stories he had. -- ========================================= Jeff Brace Vice President Vintage Computer Federation

Dan Roganti’s IMSAI 8080 for Sale
by corey cohen 24 Nov '19

24 Nov '19

To all our VCF friends and colleagues, As many of you know, long time VCF associate, contributor and friend to many, Dan Roganti (affectionately known as Ragooman) passed away in September of last year. As part of his legacy, Dan entrusted his IMSAI 8080 computer to VCF, to be cared for and sold by us, with the entire proceeds to benefit his family. His wish was that it go to a vintage computer enthusiast, to be preserved, maintained and enjoyed. VCF is going to respect Dan's wish by offering the IMSAI 8080 via a closed, single-bid email offering. This offering will go out only to the individuals who are active on this email list as of 11/15/2019. In this way, we ensure Dan's desire that the computer go to an enthusiast and not end up immediately resold, put in storage or under glass, never to be used. The IMSAI 8080 has been expertly restored to operation by our own Herb Johnson. It is in very nice physical and operating condition. The system contains an IMSAI CPU and F/P backplane with DRC 8K RAM board and Godbout active buss terminator board. Please read the in-depth description at the end of this message. Here's how it will work: - Interested bidders will submit a single offer, submitted via email to corey(a)vcfed.org. All offers will be acknowledged via email only. - Bidding will start at $1500. No bids under that amount will be considered. - Acceptance of bids will begin on 11/23/2019 at 12:01 a.m. EST. Bids will be accepted until 11/30/2019 at 11:59 pm EST. - Only the first bid from any individual will be accepted. Subsequent bids from the same person will be rejected. - The overall highest eligible bid received within the given time period will be the winner. - In all cases, date eligibility for the bid will be determined by the time stamp in the email header. - Item should be paid for within 72 hours of notification of having the winning bid. PayPal Friends and Family (paypal(a)vcfed.org) is strongly preferred as the payment method. - If the accepted highest bidder is unwilling or unable to pay for the item within the time limit, it will be offered to the next highest, valid bid. - Of course, this will be sold AS-IS, final sale. There is no warranty on the IMSAI 8080, express or implied, or any promise of specific functionality or suitability to purpose. Please remember that the proceeds are going to Dan's family, so no refunds will be given for any reason once the winner has taken possession or the computer has shipped. Ideally, the winner should pick up the IMSAI 8080 at our Festivus celebration December 7th and 8th, or shortly thereafter. If necessary, It may be shipped to the winner at their own risk and expense. There will be no exceptions to the above conditions, so please bid thoughtfully and carefully for this valuable and historic item. Good luck! Below is the statement Herb made that describes the current state of the IMSAI. Please read it carefully before bidding: > > Subject: Re: Dan Roganti's IMSAI, delivered > From: Herb Johnson <hjohnson(a)retrotechnology.com> > Date: 9/2/2019, 3:55 PM > To: Evan Koblentz <evan(a)vcfed.org> > On Saturday, I delivered Dan's IMSAI to the VCF/Infoage Museum, placed it on the workbench there. It arrived working, I did a brief test. > Cleaned up (not factory-restored) and operational. It only has an 8K memory card (and a bus terminator) so it can only run toggled-in programs to blink lights. That's what I got with it. It was short five "paddles", three blue two red. I put five reds on it as the cheapest option. Various small parts were replaced, some parts added for safety. > IMSAI delivered tested cleaned working but without warranty. > IMSAI is in good as-used cosmetic condition, f/p controls work. > IMSAI CPU and F/P and backplane: DRC 8K RAM board, > Godbout active buss terminator board. > All previous-owner mods, markings retained. > Five toggles missing/damaged: three blue two red; > replaced with five reds on controls, blue unavailable. > Tantalum caps replaced with higher-voltage new stock. > Mechanicals cleaned of loose dust, dirt, oils only. > Small rusty screws replaced; large ones cleaned up. > Cover cleaned up but left interior with tape residue. > Boards cleaned of gummy substance: rosin not removed. > Power supply caps "regenerated" successfully. > AC power lines insulated except at fuse-holder. > Bus connectors cleaned and lubricated but not warranted. > Board edge connectors cleaned and lubricated. > IMSAI performs front panel operations successfully. > IMSAI executes simple hand-entered programs OK. > DC power voltages on bus as IMSAI specs. > DC regulators on boards produce good voltages. > Motherboard lines good on all pins across bus. > NO comprehensive 8K RAM tests performed, but > simple memory front-panel operations work OK. > Regards, > Herb Johnson Thank you, Good luck bidding, Cheers, Corey corey cohen uǝɥoɔ ʎǝɹoɔ Vintage Computer Federation, a federal 501c3 designated charity corey(a)vcfed.org www.vcfed.org

Free S-Video board/mod for Sega Genesis
by John Heritage 23 Nov '19

23 Nov '19

Hey folks, Due to lack of soldering skills and proper tools.. I've decided to give up and give away a S-Video mod kit for the Sega Genesis :). https://console5.com/store/cxa1145-s-video-and-composite-video-mod-pcb.html I soldered (poorly) the 4 transistors and 3 caps to the board, but rather than risk the Genesis itself with further work (I'm also sure I can't solder the S-Video connector to wires) I'd rather just give this away. You'll get the PCB, 28 gauge wire set, S-Video and RCA gold connectors via USPS. If you want it, just PM me with an address or if you're going to Festivus I'll bring it there. Thanks! John

TRS-80 Color Computer 2 needs parts
by Al Hartman 22 Nov '19

22 Nov '19

I'm trying to repair my Color Computer 2. It has a bad keyboard. At one time there were a bunch of Color Computers in the warehouse. Are they still there? May I buy one or more if so? My Coco 2 has a 63B09E CPU, a composite adapter and a lowercase kit, so I'd like to save it if I can. Of interest to the list may be a new 68B09E Color Computer clone being created by Ed Snider. It's called "The Coco 2+" and can be seen on his website: http://www.thezipsterzone.com I'm also looking for a diagnostic cartridge for the Coco. Thanks! =[ Al ]=
