manterola Posted August 14, 2018 Share Posted August 14, 2018 Just yesterday came to my mind a memory of a device I used when I was in high school, that allow us to share a single 1050 with multiple (about 20) Atari 800XL computers in the computer lab of our school. As I remember, each "node" consisted in a small box with with a DB9 or maybe DB15 female connector and two cables: 1 SIO cable with connector (to plug it to the Atari) and a long cable with DB male connector to connect the node to the next node and so on, to you create a Trunk. Each SIO cable to each Atari might be the "Spurs". The last Atari computer, obviously, ended up very far from the Disk Drive that use to be connected to the first node, which I suspect had little different box Once a computer was accessing the 1050, all other computers got errors if try to do something with the drive, if you keep trying to get access it worked once the drive was not busy anymore. Anyone, knows about this type of networking or devices? Any name for such device? Thanks 1 Quote Link to comment Share on other sites More sharing options...
+Nezgar Posted August 14, 2018 Share Posted August 14, 2018 Reminds me of the system described in ANTIC Interview 10 with John Harris, who "developed "Classroom Star", classroom networking hardware for the Atari 8-bits" http://ataripodcast.libsyn.com/antic-interview-10-the-atari-8-bit-podcast-mark-rustad 2 Quote Link to comment Share on other sites More sharing options...
xrbrevin Posted August 14, 2018 Share Posted August 14, 2018 you had ataris in your school?! did you get any work done? hehe ..we only had acorn BBC model Bs and later on, Amstrad PCWs (yawnsville...) 1 Quote Link to comment Share on other sites More sharing options...
manterola Posted August 15, 2018 Author Share Posted August 15, 2018 There were some PC clones, Sinclair spectrum and very few commodores in my country. Mostly Ataris, so we used them for programming in turbo Basic, Logo and some word processing. We were not allow to play during computer lab time.

RodLightning Posted August 15, 2018 Share Posted August 15, 2018 This reminds me of the computer lab in my school. We had two such devices, sharing two Commodore 1541 floppy drives with two separate groups of C64s. Fond memories are of playing Infocom games sharing a single game disk between machines. I was not aware such a device existed for Atari 8 bit. That sounds great to have Atari in school. One thing, I can remember is; due to the nature of C64 disk access, those machines would just pause for however long until the disk drive was free.

The micronet is just a single box with 9 SIO connectors. No separate boxes for each machine and no 2nd DB type cables. Quote Link to comment Share on other sites More sharing options...
SS Posted August 15, 2018 Share Posted August 15, 2018 I have one of Lotharek's SIO hubs. It's awesome and totally solved my 1050 and SIO2SD's communication issue. I do kind of wish, though, that it had two output ports so that I could set up the 800XL and 600XL permanently next to each other and have them share the same SIO devices without having to swap the plugs around each time.

Mathy Posted August 15, 2018 Share Posted August 15, 2018 Hello guys @SS: Lotharek's SIO hub is the opposite of what is being talked about in this thread. His SIO hub connects multiple peripherals to one computer, what TS is talking about is a device to connect multiple Atari computers to one chain of peripherals. @All: Don't forget A2RI.

I love Lotharek's device and what it does. I just wish that it was able to perform BOTH things at the same time - connecting multiple devices *and* connecting to multiple computers.

I have a Deluxe Quintopus that I use in conjunction with my Micronet to do exactly that. In fact the switches on the Quintopus allow you to change which SIO devices are active at any given time So multiple configurations can be shared with multiple computers, all without moving any cables..... So why do I still find myself always moving cables..... :? . 3 Quote Link to comment Share on other sites More sharing options...
Mathy Posted August 15, 2018 Share Posted August 15, 2018 Hello SS Lotharek is doing something similar with SCART connectors, so who knows? Sincerely Mathy 1 Quote Link to comment Share on other sites More sharing options...
manterola Posted April 29, 2020 Author Share Posted April 29, 2020 I finally found the device, in a page of "Turbonews" magazine. It was probably locally developed. 3 Quote Link to comment Share on other sites More sharing options...

Sikor Posted April 29, 2020 Share Posted April 29, 2020 Game_Link_II (also known as Multilink): http://atariki.krap.pl/index.php/Game_Link_II Up to 7 Ataris. Quote Link to comment Share on other sites More sharing options...
manterola Posted April 29, 2020 Author Share Posted April 29, 2020 BTW, the device I am talking about is the one shown on the bottom of the page, the one with the db9 connector. They were used to share a single Atari disk drive and/or printer with multiple Atari computers (no communication b/w the computers). This make a lot of sense in a time and place (Chile around 1989-90) were a disk drive cost were about 1.3 to 1.5 times the cost of a pack with 65XE, joystick and XC12 cassette recorder. And the price of computer pack was already high:about US$500 maybe more (money of today) depending on the exchange rate. Quote Link to comment Share on other sites More sharing options...
StickJock Posted April 29, 2020 Share Posted April 29, 2020 I remember a computer lab in college that had a bunch of Atari 800s that all shared a single hard drive. IIRC, they had cables plugged into the upper joystick ports. I don't remember if it was just port 4, or if it used both ports 3&4 (probably the latter). In high school, we had a lab with a couple of dozen Atari 800s, each having (I think 2) 810 floppy drives, monitor & 80 column Atari printer (825?). I guess that they must have had an 850 as well to go with the printer. 1 Quote Link to comment Share on other sites More sharing options...

Up to 8 Ataris. Most programs are for 1 player per Atari and thus 8 players max., but there is one (or maybe two?) program(s) that allows split screen and 2 players per Atari for a max. of 16 players...

StickJock Posted April 30, 2020 Share Posted April 30, 2020 Yeah, I was thinking Corvus, but it was 35 years ago so I wasn't sure. I think that we also used Wordstar on some MPM (Multi-user CPM, iirc) systems. Quote Link to comment Share on other sites More sharing options...

manterola Posted May 3, 2020 Author Share Posted May 3, 2020 (edited) Thanks! So the mystery is solved.. It's quite a nice collection the guy in the link has. I encourage everyone to. Check this out, there are some nice and not known devices, boxes, manuals, etc. The guy also has the manual I remembered in Spanish for the 65xe/130xe. I did not remember it was for both computer models. Edited May 3, 2020 by manterola Quote Link to comment Share on other sites More sharing options...
