Dayton Microcomputer Association

DMA is a 501c3 nonprofit, one of the first computer user groups formed in the nation.
Our mission is to promote interest and knowledge in all facets of computer technology.
We are a valuable resource for all things digital.

Out of concern for the health of our membership and guests and in accordance with Ohio restrictions on restaurants, we had canceled many in-person DMA meetings. The DMA Trustees have decided to augment our typical face-to-face meetings with the use of the on-line Zoom product, continuing our meetings as a hybrid. People can gather in person when allowed, and the meeting is also carried on ZOOM. Keep checking this page and also DMA Meetup Events page for updates. If you have questions, comments, or suggestions, feel free to visit our Contact us page and let us know.

Open Source for Processors
Presented by Gary Turner

RISC-V pronounced “risk 5”, is an Instruction Set Architecture (ISA) based on Reduced Instruction Set Computer (RISC) principles. The ISA is an abstract model of a CPU. Current ISAs include x86 and ARM; older versions were SPARC and VAX; those from the early days Z80 and 6502. Most ISAs must be licensed from a manufacturer. Being open source, the RISC V does not require fees and makes CPU development feasible for even small development teams. RISC V promises to allow processors to be developed for a wide range of applications.

Gary Turner will attempt to unscramble the acronyms. Gary is a charter member of DMA, past president, long time trustee, and frequent presenter. He leads the Linux SIG and Networking SIG.

DMA Shell Accounts
Presented by Mark Camden

Several DMA members who have requested shell account space on our web server have asked for better instructions on how to log into their accounts and how to upload files. Mark dug up the details. He will give a short presentation on how to access and maintain these accounts. Shell accounts can be requested for a one-time charge of $10 using a DMA membership form.

Mark Camden is webmaster for the DMA1.org website. He keeps the info on the site up to date and also keeps an eye on security issues for the site.

Our meeting starts at 7:00 pm. DMA members will receive an invite by email for Zoom. Others may request an invite using http://www.dma1.org/contact us/ Or… join us at TJ CHUMPS, 7050 Executive Blvd, Huber Heights OH
