It was the most amazing experience to see this text and ASCII/ANSI art appear on my screen that was running off somebody else's computer. It's hard to describe the feeling I got when I realized I was connected to somebody else's computer somewhere within my city. It felt futuristic. At first I felt like I was being watched (possibly) by whoever owned the computer, seeing what I was doing on the system.
Also neat was I was using an IBM PC and some of the BBSes I connected to were using Apple computers or something else. It blew my young mind.
Eventually I ran my own BBS and made my own BBS door games that I made a little bit of money with. I released them as shareware and people would send checks in the mail to me to register the software.
I still have the data from my BBS that I could probably run in DOSBox to log into for old time's sake.
It was a IBM-PC or XT, with two Seagate half-height 20MB ST-225 hard disks laying to the side of each other in the two bays--don't stack them, they will fry each other even with added fans installed!
It made such a ozone smell in my bedroom I ran a dryer vent hose from the exhaust fan out my bedroom window.
That's about all I remember, but I do have a copy of the software if anybody needs it.
I was more into WWIV. It ran OK on the whitebox DTK Computer clone build from the very local computer shop that the guy was running in what had been the garage behind his house.
But the 16450 serial port UART in that 10MHz 8088 barely kept up with the 14.4k SupraFAXModem that came a bit later; keeping that stable was tricky.
I miss the grunts from the ST-225 at startup.
At one point someone donated an ST-419. That was a full-height disk that, when formatted MFM, held only 15 megabytes. But 35 total megabytes was a lot more than the 20 that the ST-225 offered.
It didn't fit inside of the desktop case at all so the lid was always off and things were just kind of stacked up, including the extra power supply that I used for staging power turn-on.
Because, you see: That ST-419 was so slow at spinning up and becoming usable that the controller would completely give up on it from a cold start. So I'd fire that up first, and give it a moment, and then power up the rest of the system.
Other fun hacks included a 2-megabyte EMS memory card. That thing had 72 socketed DIP chips on it and it did not arrive populated. Half of the memory served as a disk cache for Stacker and the other half as a RAM disk that got populated at every boot with some often-read, never-automatically-written BBS stuff that callers previously had to wait around for.
Anyway, I made a number of great friends back then with the BBS. I talked to one on of them on the phone just tonight, and a bunch of others of us still hang out together like we started doing 35 years ago.
Way back then, they named that first computer "The XT from Hell".
Z80 is (still) an 8-bit CPU with 16-bit addressing. It cannot access more than 64kiB at a time. The hardware and the software needed to overcome that limit was worth more than an 8088/8086 (or compatible CPU) with MS-DOS and Telix.
In 1993,the age of 80286 and 80386, 8088/8086 were considered low-low-end CPUs, let alone the Z80, even in Mexico.
Not pointing my finger, just stating some facts.
