Great! Hope my stuff isn’t in anyone’s way. Get there as soon as I can. If anyone has interest in the Mitsubishi CRT let me know. As long as my computer will work on another display. It is way too large for me to deal with (cost/benefit analysis) Sent from Yahoo Mail for iPhone On Sunday, April 25, 2021, 11:06 AM, Martin Flynn <maflynn(a)theflynn.org> wrote: VCF guys are still in the makerspace!

Fwd: [Coco] Van Load of COCO Stuff
by RETRO Innovations 23 Apr '21

23 Apr '21

I hate to bother folks and impose on good graces, but I do hate to see stuff get dumped, even if it's not a biggest of iron. Is there any chance someone nearby this location is feeling particularly generous and might consider grabbing these items? I have a couple folks near the area who can store, and I hoping to attend VFC-E and could drive my larger vehicle to pick the items up at that time.

I have piles and piles of COCO stuff including monitors, computers, disks, manuals, peripherals, etc and could nearly fill a large van with it. Long story short...I have no time to sell anything g or ship it here or there as I currently live in Charleston already (started a franchised coffee shop) and will be moving my family down after we close on our house sale next week. I DO NOT want all this stuff lost to history and looking for someone who would haul it away fir the good of the community. Would be a great haul for Glenside for use in an upcoming COCOFest auction as well. Reach out to tjseagrove at yahoo dot com if you would like to haul this away.

Re: Lend VCF Commodore 1702 monitors for TV show (Jeffrey Brace)
by MikeWillegal 23 Apr '21

Hi Jeff, You need to charge enough so that when they do go through with a deal, all the uncharged expense, overhead, time and process is worth the overall effort to the organization. I do understand that for a (mostly) volunteer organization, that it is very difficult to set a cost basis for uncharged time. One reason I cut way back on selling PCBs and kits to the vintage computer market is that I wanted more time to work on other projects and I was basically making below minimum wage on those products. If the organization thinks spending it’s energy on other projects would be more beneficial to the organization, you should consider raising the price or dropping the program entirely. Obviously, if the cost is too high for the prop houses, then they will go elsewhere on their own accord. regards, Mike Willegal

Looking for OG LaserWrtier Parts
by Jason Perkins 23 Apr '21

23 Apr '21

I probably should have sent this earlier... Does anyone coming to the swap meet have any original Apple Laserwriter parts they'd like to offload? I'm specifically looking for the I/O board, and the 36 pin cable which connects it to the DC control board. Thanks! -- Jason Perkins 313 355 0085

I have a small car and I am putting items on the list that I can carry to the event. I happen to have a rather large Apple III with a monitor and software and stuff I want to sell, but if no one wants it I won't bring it. I took a bunch of pictures, I'm not looking to sell the II+ but if you want make an offer and if I'm good I will let you know https://imgur.com/a/mM2BpG4 If no one wants it, then I am adding other stuff to the spreadsheet Please let me know

Swapmeet Repeater Talk-in
by jsalzman＠gmail.com 22 Apr '21

22 Apr '21

For those who are going to be attending the Swapmeet this Saturday, this is just a callout to those with Amateur Radio licenses. Since we opened up the event to include Hamfest related goods, we have secured the use of a local repeater for an event talk-in. If you, as a licensed HAM, would be able to help respond to any direction or info requests that come in, please let me know. The repeater is in the Asbury Park area, so it might be reachable with a 5w handheld. 147.045+ PL67 Thanks, Jeff Salzman

Re: [vcf-midatlantic] Bag-o-chips sorting, storing, testing
by Bob Applegate 22 Apr '21

Do any of these testers perform tests at real speed or are they just a bunch of I/O ports that software writes to, then reads back the values to make sure they are correct? That would week out most bad chips, but I’ve had quite a few chips that passed those tests only to fail in a real circuit because they were no longer switching at full speed. ESD damage? Who knows. I ended up building some of my own testers where the chips under test are in a live circuit and their outputs are latched and compared to expected results. As far as RAM tests go, a common failure scenario is where they can pass memory tests but then not work in the real circuit because of timing. I like to have memory tests that run out of ROM and not use the RAM except as a test target, then use a RAM based tool so that the code running the test is also in the same RAM. Access to memory under test is really slow for any test running in ROM… lots of code execution in ROM, write a byte, lots of ROM code, write a byte, etc. By running the memory test in RAM then it is constant access to the device being tested. Some chips fail the latter case. Just my two cents.

Do you use their Windows software or something else? I use minipro in Linux for PROMs and flash, but minipro doesn't have chip-testing capabilities.
