Hmm, that is interesting, why was that version originaly hosted on 3drealms site? Probably nothing, somebody there just wanted to share a cool picture. But what if that were an early apogee shareware distribution bbs?
In the alcove on the right, I think I'm seeing 66-blocks, breaking out the phone lines that must be routed to each machine. Two blocks stacked, each with a fanout of wire on the right side.
wait, are you OP? or did you happen to find a high res version of the same paper-copy picture that OP supposedly was given 30 years ago and then scanned and then threw out. or did OP make it up? or is OP just a bot?
maybe i'm a bot.
anyway i used to call into BBSs back in the early 90s and the thing I'm remembering is that they survived mostly on donations, and now that I am seeing the infrastructure that supported those systems and recalling the price of hardware back then I'm starting to second guess everything I thought I knew.
In this picture it seems that all machines have a 3.5" floppy disk inserted. Maybe they had no hard drive and only booted from floppy and then ran software over the network?

Scott Miller - Apogee/3D Realms Founder
@ScottApogee
BBS's (bulletin board systems) were the backbone of the online world before the Internet came along in 1995. Apogee teamed up with Dan Linton's BBS, called Software Creations, and we poured $200k+ into it to grow it to nearly 140 call-in nodes with a T3 (high bandwidth) line.
This makes me wish I took photos of Diversi-Dial (aka D-Dial) setups, which somehow impressed me more due to how much they accomplished with much much less hardware.
They were able to set up a 7 x 300baud modems in real-time chat system on an Apple ][ . The original marketing called it a CB (Citizens Band) Simulator. They were able to run up to 1200baud, but I never saw one of those functioning.
As if 7 people chatting through a single 6502 wasn't impressive enough, many of them dedicated one or two of their lines to interlinking with other D-dials.
And the larger ddial sysops would daisy chain multiple Apple IIes together. A connector would take up one port on each machine. Two machine would give you 12 modems. Each new machine after the second would add space for 5 modems (-1 on old machine, +6 on new machine). For the sysop it was a big investment for very little, if any, monetary reward. I remember a user account would cost $5 a month.
Our ddial was a few towns away so we bought a line in the exchange in between that would forward to the ddial. This way we would not pay a bunch on long distance calls.
I am surprised by the assumption that each box could only handle one modem. I seem to remember that some DOS BBS packages could handle multiple modems/users concurrently and only needed multitasking operating systems for ādoorā programs. Am I misremembering?
āas modems got faster, supporting 16 modems on a single machine became impossible, and it was often cheaper to buy a new commodity desktop PC rather than a much more expensive machine with a 16-port serial card capable of handling the IO.ā
A guy who was local to me, when I was a kid, wrote multi-user BBS system (called "MUBBS" originally-- I don't remember what the name was changed to later) in Turbo Pascal that had a preemptive multitasking loop running in x86 real mode to handle multiple lines simultaneously. The coolest part was the console was just a "line" so you could logon to the board and interact while somebody was online with the BBS, too. Most other DOS BBS packages were only available for the SYSOP or the caller individually.
Edit: Ugh... I'm gonna have to go back to floppy images to find it. There's a "MUBBS" for Mac from 1992 showing up in search engine results but that's not the one I'm thinking of. It was more like 1989 or 1990.
Even for a standard PC, you could buy a 16 port serial card and hook it up to 16 modems, either discreet devices or the dedicated ISP kit which might support dozens of incoming calls (possibly on a single bearer) via various means. Telebit netblazers and then ascend maxs were common in those days.
Those were the days. I still believe nothing replaces the camraderie of the small, local BBSs. The large ones were good too, but these tended to resemble the modern Internet forums a bit more.
My roommate circa 1989 had a bunch of Apple IIās with multiple modem cards per machine to run a bulletin board. Not sure why an Apple II could support multiple users logging into the BBS via multiple modems but DOS based machines could not.
Office chair technology also has really advanced since then (looking at the chair on the picture, which is commonly seen near computers in photos of this era)
Not mentioned but very important was the number of inbound telco lines installed. Equally important was making sure the local phone company properly configured the hunt group for those lines. Without a properly functioning hunt group it would be very difficult to optimize the allocation of telco connections to all the users connecting and disconnecting.
Also, it was unusual at the time for a local phone company to receive a request for 25 lines (or more) to be installed in the basement of a residence. They would generally push back thinking you were running a bookie operation or some such.
> do you think "wow, cool, they got to wrangle all of that", or do you think "OMG they had to wrangle all of that"?
I touch on similar point of view discussing digital audio work I do for fun. I use CSound, which I've heard described as "assembly language for audio", and I think that's accurate.
Anyway, when I first, FIRST started, and got a tiny bit familiar, I thought "Wow, I can do anything!" but quickly realized I was also responsible for everything. No free lunch.
> It's possible they managed to do some rudimentary multitasking with DESQview (or worse...) and so supported two whole users with each box. Does that mean they had to be at least 386s to do protected mode? Or was it virtual 8086 mode? I (fortunately) have forgotten the finer points of how that stuff used to work. I DO remember how damn crashy a box became when you ran it "under DV". Constant system freezes. Yep.
I don't recall DESQview to be all that crashy. I was aware of a number multi-line BBSes that used it (just in the 416). Some BBS software called out its use specifically:
DESQview was absolutely not crashy. I ran several different types of BBS software in it without issues. The "DESQview (or worse...)" comment raised the hair on the back of my neck. DESQview was revolutionary at the time and I was annoyed at having to use Windows many years later.
ASCII windows may not have been everyone's cup of tea but I loved it.
The OS that was running on these is irrelevant, the important part is the BBS software.
And these usually ran quite a few lines per box, sometimes they would use external racks of modems, but I'm not seeing that here so maybe these were using internal modem cards, so maybe 6 per box, but if they were using external modems it could easily be 12 or more, with the PC cards hosting multiple serial ports, 4, 6 or even 8 per card.
Typically a card would have a single large connector at the back and then a pigtail with a DB9 or DB25 (yes, I know) for every modem.
"usually" and "typically" are doing a lot of heavy lifting here :)
Access to knowledge, equipment, and budget varied dramatically prior to widespread internet access. Someone setting up a BBS might not even know about multi-line modem cards or serial port expansions. Even if they knew about them they may not have been able to reasonably obtain them. Or they may have been operating on donations, surplus, or discount equipment. Or they simply may not have had the luxury of time to research all of that as user demand meant they were too busy laying tracks in front of the train.
Many BBSes ran on 1-2 lines per PC because that's what they understood how to build or the hardware they had access to. You might be surprised at just how many lines some BBSes setup this way had!
People forget there was a time that anything outside the standard PC was extremely expensive, often had flaky or nonexistent software support, locked you into a fly-by-night vendor that might go out of business tomorrow, was only available via a distributor who wanted to have you talk to a "sales consultant" before they'd sell you something, etc. Many many people chose sub-optimal implementations because it was an off-the-shelf PC they could replace at any time with trivially simple software requiring no special CONFIG.SYS drivers or TSRs to fiddle with. Especially if you'd ever been burned previously.
The OS was relevant if your BBS software was limited to a single simultaneous user, like many of the early DOS BBSes. The late 80's "PCBoard" BBSes I'm familiar with needed one PC per user, plus a file server with Netware.
I remember thinking that I would reach absolute peak-coolkid if I could start and run a BBS. I even installed WWIV and DesqView to fuel the fantasy and prepare. But my parents didn't understand technology and couldn't grasp why I wanted to hook up (and pay for) a second phone line for the house. So, unfortunately I would remain a mere luser until I went off to University where the Internet was just getting popular and 10-Base-T ethernet drops to the dorm rooms were standard, and I very quickly forgot all about BBSing.
I can recall people being very impressed at unix systems being able to handle many clients, and being personally confused at the idea of a computer only being able to handle a single user.
I can recall people being very impressed at unix systems being able to handle many clients
That seems odd to me, too, because before DOS and the Commodore 64/Apple ][ era, multi-user systems were everywhere.
Not just mainframes and minicomputers, but there were many dozens of multi-user systems based on CP/M, MP/M, and other operating systems. Even Tandy had them.
The revolutionary part of the "personal computer" era was that it was your "personal" computer. You finally didn't have to share it with anyone.
I remember dialing up to a BBS in the area in 1990 that had 4 phone lines. That was amazing at the time when most BBS only had 1 line.
But I do remember downloading text files FILE.IDZ about other BBS, and reading some magazines that mentioned other BBS systems that had 32 and more phone lines but you had to pay. That seemed like it was just on another level in another part of the world that seemed like fantasy compared to the area I was in.
Same here! This brings me back. And makes me feel old. Dialing the big BBSes like this one were rare special occasions for me, due to the cost of long distance.
If it's like the old ISPs I was familiar with, they didn't. The POP (point-of-presence, 100's of modems, plus several terminal servers, routers, etc.) would generally be in some basement without any cooling at all. There would literally be warped plastic.
Does BBS still have a usage nowadays? I feel HN is not too different -- and actually offer less than a BBS -- back then there are a lot of goods on a large BBS. And it's easier to mix a pic with text, but I could be wrong.
Also thinking it's a lot environmental easier to host a BBS than a Discord server.
Would love a technical explanation of how all that stuff worked by someone who did that kind of stuff in those days. In the old days I personally never saw anything bigger than a four line BBS. But I remember reading about that one in shareware README.TXT files
Wouldn't mind hearing war stories from the cdrom.com guys as well.
I remember trying to set up a bbs on my pc in the 80s and I didnāt have a separate phone line so I just put it on while I slept. Then people started calling and annoying my parents with daytime modem calls, because I was like 10 and I didnāt think through any of this.
I set up a uh war dialer around the same age over night and my mom got some pretty upset calls the next day.
She had no idea who these people were or why they were upset. I donāt think I copped to it, it was not an easy thing to explain but I did not do that again.

If they were really badass, they had a rack of Telebit modems. (Telebit made 68020 based modems that did 56+ Kbps long before a 56K standard, and literally had more compute power than most of the computers they were connected to.)

I'm fairly certain you are correct. I remember the MajorBBS could handle multiple lines on its own.
I knew a couple of local DOS BBSes that ran multiple lines with PCBoard under DESQview.
That assumption feeds into the moral of the post and its followup
Serial ports are a fun thing to learn about, computers had more than one. Now with USB, computers can have many serial ports.
Those were the days. I still believe nothing replaces the camraderie of the small, local BBSs. The large ones were good too, but these tended to resemble the modern Internet forums a bit more.

Would these machines have been networked with CAT-3? Daisy chained phone cords?
More likely coax. 3com 509c network cards. Much less infrastructure to have a lan that way.
IBM had a network that ran over phone cords that were daisycbained from one node to the next.
It's also possible they used coax, either ethernet (10base2) or Arcnet.
Depends on the exact date.
I never worked with DOS BBS systems, so I can't say about this photo specifically, but the ones I did work with had between one and four dialup modems hooked up to each machine, depending on its capabilities. They did "networking" through a store-and-forward messaging system. It wasn't networking as we'd recognize it today.
