content: Hi folks,We've had this Trainer board and manuals laying around for a long while now and I want to pass it on to a good home. On Monday I'll scan the two manuals so that can be available to the, I'm sure, wide audience of interested people.I want to pass this on to someone rather than throw it away. There's one listed on ebay for $300 which seems quite steep as it doesn't seem to be actually collectible. If anyone feels it is worth having PM me with whatever you feel is fair and I'll ship it to you.Original propaganda:With the Graymark G-809 Micro-Processor Trainer Model Kit students learn the essential concepts of computer operation by building & programming a micro-computer! The 25-lesson course leads the student through hardware & software experiments, teaching circuit design, troubleshooting techniques, programming, binary, hexadecimal & mnemonic operation, and other topics. Designed to teach micro-processors at the secondary & post-secondary levels, the 8085 based Trainer uses CMOS and TTL integrated circuits. Instructor-controlled fault insertion and easy-to-augment lessons make the Trainer a powerful teaching tool. Can be used as a stand-alone Introduction To Micro-Processors course, in conjunction with existing curriculum, or in a self-study program. Hurry and get the Graymark G-809 Micro-Processor Trainer Model Kit today!

content: Wow! I recall that in the 70s I assembled the Intel 8085 kit. I think it was called the SDK-8085. Somehow similar to this board. That was about 40 years ago ! The 8085 was a great packaging improvement over the 8080 !I guess I must be really old.

content: I know what you mean! In May 1976 I went to work for a company that was setting up to produce a dedicated word processing computer for news paper reporters. We started with an 8080 based design but then modified it to use the 8085. Heady stuff in the 1970s! At the time we thought the 8085 was a hell of an improvement over the 8080! That was the first time that I ever saw a floppy disk. We where buying 160k (?), single sided units brand new from Shugart at something like $320 each. I STILL have some of my 8080 and 8085 kits and development systems including several Intel MDS-800s and MDS-225s that I bought later but I probably haven't even turned one on in over 5 years now. I used to get a real kick out of seeing how SMALL I could write code. In those days, every byte counted!

content: Good afternoon,I saw your posting RE- The Graymark Micro-processor Trainer Model 809. During my College days I built one of these and I still have it, but I don't have the manuals. If there is any way that you can send me a copy of the manuals I would be willing to pay you something for them and off coarse pay the shipping or if they can be e-mailed to me some how. I want to have these manuals so that I can have mine complete. Please reply. I can be reached by e-mail or by phone ThanksJake

content: I would love to have/work on something like this - I've been doing a lot of reading and learning about 4004 and 8080 processors and the beginning of computing as we know it. I'll send a PM.

content: That's neat. Reminds me of the 8086 trainers that were used when I was working on my EE degree.
