The HP-85B Microcomputer, Part 2 Hello, and welcome to episode 64 of the Floppy Days Podcast, where old computers come to live.  I’m Randy Kindig and I’m happy to bring you this episode this month.  This episode is Part 2 about the HP Series 80 line of microcomputers.  Last month I interviewed 2 well-known members of the HP Series 80 community, Everett Kaser former HP engineer who worked on the Series 80 and runs kaser.com and Vassilis Prevelakis of series80.org.  This month, they are back to help me talk about the history of these fabulous machines.  It’s a fascinating conversation with two gentlemen who have a lot of love of and knowledge about these machines. I want to thank Everett for providing the intro to this episode with his memories of the Series 80. Before getting into the meat of the program, I do intend to talk briefly about any new vintage computer acquisitions, upcoming shows and feedback. Ok, let’s fire up the ol’ HP-85 and see what we can learn.

So, for this episode I enlisted the aid of Paul Nurminen (aka Nurmix), who was also an attendee and exhibitor/vendor at the recent Vintage Computer Festival Southern California, to help me do a follow up discussion of that show.  We discuss our exhibits, other exhibits of note, our general thoughts about the show, and a whole lot more. I hope you enjoy this.

If you want to know more, I’ve recently published interviews with John Grant, Steve O’Hara-Smith, and Gerald McMullon concerning their involvement with the New Brain back in the day.  I also, in the most recent episode, discussed tech specs around the machine with my co-host. Regarding that, in that last episode, to help me talk about the machine, I enlisted Chris Espoinidis to co-host this episode.  Chris manages the New Brain Emulator site from his home in Greece.  Even though Chris created one of the premier New Brain emulators in existence, and that was the primary focus of his Web site initially, his site has become one of the best places (along with Gerald McMullon’s Website) to get any and all New Brain information (which quite honestly is quite sparse). The focus of this last episode detailing the machine, Chris and I will cover things like peripherals, Web sites, books & magazines, software, using the machine, emulators and all of the topics that have become the standard for machine coverage on Floppy Days.  This episode will complete all the details we know on the New Brain, with the intent to impart every bit of information to you that I could find about this little-known machine. Before we do that, I will talk about upcoming shows.

As you know, I’ve been hot on the trail of pioneers who were involved with development of this machine.  I’ve recently published interviews with John Grant, Steve O’Hara-Smith, and Gerald McMullon concerning their involvement with the New Brain back in the day. In this episode I move more into discussing details of the machine and its impact on the home and small business market in the 1980’s.  To help me talk about the machine, I was able to track down Chris Espoinidis and convince him to co-host this episode.  Chris manages the New Brain Emulator site from his home in Greece.  Even though Chris created one of the premier New Brain emulators in existence, and that was the primary focus of his Web site initially, his site has become one of the best places (along with Gerald McMullon’s Website) to get any and all New Brain information (which quite honestly is quite sparse). The focus of this episode, and the next, is to cover things like tech specs, Web sites, emulators and all of the topics that have become the standard for machine coverage on Floppy Days.  This particular episode contains an interview with Chris, and then goes into great detail concerning the technical specifications of the New Brain.  The next episode will cover all the other details, with the intent to impart every bit of information to you that I could find about this little-known machine. Before we do that, I will talk about new acquisitions and upcoming shows.

Hard to believe we’re coming up on the end of 2023.  It was Feb. 2013 when I took the first halting steps in producing a podcast, so we’re coming up on 11 years of Floppy Days very soon. We are currently covering computers that were released in the year 1982.  We are very early in that year, with lots of other computers to be covered. This episode is about a machine that was developed in the UK.  It was pretty much unknown in the United States and even in the UK didn’t get much traction.  The machine I’m talking about is the Grundy NewBrain.  There are a lot of unique things about this machine that you’ll discover through the history episode, these interviews and the episodes that cover the details. I’ve been fortunate enough to be able to contact a few people who were involved in the development of the machine.  I’ve published interviews so far with John Grant and Steve O’Hara-Smith.  This episode is also an interview episode, but this time with another key member in its development: Gerald McMullon.  Gerald has a lot of interesting information to share about the NewBrain, including information about its development and support of the machine after its release. I have been able to contact some other principals in the development of the NewBrain: Basil Smith and Mike Wakefield.  Unfortunately, Basil has had a lot of recent requests for interviews, so I’m waiting in line for that.  However, should I be able to talk with Basil and/or Mike, I will of course bring all of that to Floppy Days in future episodes. This current episode is the end of the interview episodes around the NewBrain at this point in time.  Next month, and actually likely the next 2 months, we will be covering the details of the machine such as tech specs, emulators, software, newsletters, peripherals, web sites, etc.  That will happen with a special co-host that I’m going to leave as a surprise for right now.   New Acquisitions   TI95 cassette interface - https://github.com/molleraj/ti95interface    AquariCart + 32K RAM - https://www.ebay.com/itm/124471439128    MC-10 3-button joystick pad - https://www.youtube.com/watch?v=ZzsGst8HAiI    Upcoming Computer Shows   Vintage Computer Festival SoCal - February 17-18, 2024 - Hotel Fera Events Center, Orange, CA - vcfsocal.com    Interim Computer Festival SPRING - March 23rd and 24th, 2024 - Intraspace, Seattle, WA - https://sdf.org/icf/    Midwest Gaming Classic - April 5-7 - Wisconsin Center, Milwaukee, WI - https://www.midwestgamingclassic.com/    VCF East - April 12-14, 2024 - Wall, NJ - http://www.vcfed.org    Indy Classic Computer and Video Game Expo - April 13-14 - Crowne Plaza Airport Hotel, Indianapolis, IN - https://indyclassic.org/    VCF Europa - April 27-28, 2024 - Munich, Germany - https://vcfe.org/E/    The 32nd Annual “Last” Chicago CoCoFEST! - May 4-5, 2024 - Holiday Inn & Suites Chicago-Carol Stream (Wheaton), Carol Stream, Illinois - https://www.glensideccc.com/cocofest/    VCF Southwest - June 14-16, 2024 - Davidson-Gundy Alumni Center at UT Dallas - https://www.vcfsw.org/    Boatfest Retro Computer Expo - June 14-16 - Hurricane, WV - http://boatfest.info    Pacific Commodore Expo NW v4 - June 14-15 - Old Rainier Brewery Intraspace, Seattle, WA -  https://www.portcommodore.com/dokuwiki/doku.php?id=pacommex:start    Kickstart Amiga UK Expo - June 29-30 - Nottingham, UK - https://www.amigashow.com/    Southern Fried Gaming Expo and VCF Southeast - July 19-21,  2024 - Atlanta, GA - https://gameatl.com/    Fujiama - July 23-28 - Lengenfeld, Germany - http://atarixle.ddns.net/fuji/2024/     Silly Venture SE (Summer Edition) - Aug. 15-28 - Gdansk, Poland - https://www.demoparty.net/silly-venture/silly-venture-2024-se     Portland Retro Gaming Expo - September 27-29, 2024 - Oregon Convention Center, Portland, OR - https://retrogamingexpo.com/    Silly Venture WE (Winter Edition) - Dec. 5-8 - Gdansk, Poland - https://www.demoparty.net/silly-venture/silly-venture-2024-we     http://chiclassiccomp.org/events.html    Facebook show schedule - https://www.facebook.com/VintageComputerShows/    Interview   Gerald’s Website - http://www.mcmullen.com    NewBrain Nutshell History by Gerald at Binary Dinosaurs - https://www.binarydinosaurs.co.uk/Museum/Grundy/gerald.php    NewBrain history article by Gerald in Micro Computer Mart newsletter -  https://newbrainemu.eu/component/option,com_docman/task,doc_download/gid,96/Itemid,52/
