New toy: Micromedic MACC II Assay Compucenter (6800 computer)
by Neil Cherry 24 Apr '24

24 Apr '24

Surprisingly, my lower offer for this computer was accepted. I now have a "Rare Motorola 6800 EXORbus? System Micromedic MACC II Assay Compucenter Boots Up" Might be Motorola Exorbus system but that's not important. I'm pretty sure I can run Flex and that the 'Boots Up" is the Motorola MIKBUG rom monitor prompt. I see 4 serial ports (RSR232, current loop and parallel port). I need a bit of info on the keyboard. It appears to be a serial keyboard. Since I don't have one I expect I can build something that sends ASCII at 110 or 300 and it will work. If not, I disassemble the 2716 (5V). I'm good with that. Any ideas? BTW, the Micromedic MACC II Assay Compucenter interfaced to Nuclear Medicine test equipment. -- Linux Home Automation Neil Cherry kd2zrq(a)linuxha.com http://www.linuxha.com/ Main site http://linuxha.blogspot.com/ My HA Blog Author of: Linux Smart Homes For Dummies KD2ZRQ

OT: Camp Invention Instructors needed
by Jeffrey Brace 23 Apr '24

23 Apr '24

Hello everyone, InfoAge needs instructors for the Camp Invention that rents space during two weeks in the summer. This link <https://vcfed.org/wp-content/uploads/2024/04/2024-Camp-Recruitment-Flyer_Fi…> is the flyer to explain it. I was the instructor at Camp Invention the last 3 years and have been "promoted" to Camp Director this year. We are looking for two instructors to teach. There are two separate weeks of camp. We already have children signed up for the camp for both weeks. We also need a camp parent who helps promote Camp Invention. This parent doesn't need to attend the camp, but will get free tuition to the camp in exchange for helping to promote the camp. Any questions? Please email campinvention(a)infoage.org! Thanks!

Re: [vcf-midatlantic] Upcoming events at System Source in Maryland

Why try to foster hostility and competition between the swaps? They are both very fun and worth going to. I think a month is a decent amount of buffer time between both. FWIW, some of us travel pretty far to the NJ events, and stuff like the System Source workshops/swap are a little less brutal to get to. I have plenty of friends in the NoVA/general DMV area who would agree...

Sure, in 25 years or so when the stock actually starts to dry up. -Dave On April 20, 2024 10:42:36 AM Sentrytv via vcf-midatlantic <vcf-midatlantic(a)lists.vcfed.org> wrote:>---------- > Re: [vcf-midatlantic] Z80 end of life only months away > From: Sentrytv sentrytv(a)yahoo.com > Date: Apr 20, 10:42 AM > To: vcf-midatlantic vcf-midatlantic(a)lists.vcfed.org > CC: Jeffrey Jonas jeffrey.scott.jonas(a)gmail.com > > Does that mean that all of us were holding on to various Z 80 processors now have I hope of selling them for more money? > > Sent from: > My extremely complicated, hand held electronic device. > >> On Apr 20, 2024, at 9:08 AM, Jeffrey Jonas via vcf-midatlantic <vcf-midatlantic(a)lists.vcfed.org> wrote: >> >> ?https://www.mouser.com/PCN/Littelfuse_PCN_Z84C00.pd >> <https://www.mouser.com/PCN/Littelfuse_PCN_Z84C00.pdf>f >> https://hackaday.com/2024/04/19/end-of-life-for-z80-cpu-and-peripherals-ann… >> >> The memo dated April 15, 2024 says the last time to buy is June 14th. >> Only 2 months warning :-/ -- Dave McGuire, AK4HZ New Kensington, PA

Not yet, even though it’s EOL I imagine they will still be in stock for a while, but this will make getting chips for all the kits a bit harder might make the prices go up on hobbyist projects in a few years.
