RBBS-PC. I used to call one of those sometimes -- but it was in the next town over, and in-state long-distance charges were more costly than calling across the country was. It was a nice board: Two lines, lots of software (IIRC 1.2 gigabytes), with 19.2k Telebit Trailblazers at a time when 9600 was still considered fast.

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".
