Re: Anyone ever use a 300/1200 baud modem using 5 1/4" floppies
I've got a functioning 8088 machine out in the shop. Bought a pallet of old computers from the state surplus many years ago, wanted one for a database out there. Sold most of the others after mixing and matching, still have these three old original IBM machines tucked away. Also have a functioning Vic-20 with tape drive stored away in the shop attic. I also ran a BBS on a C-64 for a while in the mid 80's, 300 baud modem. Remember the disk notcher that would let you write to both sides of a 5.25"?
Anxiously awaiting Dr. Savage's return to the airwaves.

Re: Anyone ever use a 300/1200 baud modem using 5 1/4" floppies
The first computer I ever used was an ALWAC IIIe at Oregon State. It used vacuum tube logic, and a rotating magnetic drum about 3' tall for memory. Program input was by punch tape. My lab partner and I entered the program independently, then held the two tapes together to the light to make sure they were identical. A typo meant flunking the lab.
History of Computing in Turku
My first home computer was a Reynolds and Reynolds TC-1000. Z80 cpu, CP/M OS, 5" screen, dual single sided floppies and a built in 300 baud modem. It was originally a smart terminal for a PDP-11. Besides word processing and database (no spreadsheets in those days), it had a copy of Microsoft MBasic. I loved that program. I should have bought Microsoft stock.
Speaking of spreadsheets, Steve Jobs wasn't the genius that put Apple on the map. It was Dan Bricklin, who sat down and invented the spreadsheet for the Apple II. For a couple years, if you wanted a spreadsheet you had to buy an Apple II, which sold all their computers for them.

Re: Anyone ever use a 300/1200 baud modem using 5 1/4" floppies
My first computer was a Heath H8, then upgraded to a Heathkit H89 with an actual 5 1/2 in hard sectored floppy and a built-in monitor. Then the ultimate computer - a Kaypro IV with dual floppies running CPM. The H8 didn't have a monitor - output was in octal via the lights on the front. Programs were loaded from a cassette player or tape drive on a teletype. The 300 baud modem was considered fast.

Re: Anyone ever use a 300/1200 baud modem using 5 1/4" floppies
My son and I ran a BBS called the "Borg". I guess you can figure the theme for it. We had hundreds of trek pictures. A bunch of online games. US Robotics offered Sysops a discount on their high end external modem. I got one of those 33.6 which was flash upgradable. Our phone line maxed at a little above that. We had message forums linked thru the Fido network. It was a lot of fun. -kid

Re: Anyone ever use a 300/1200 baud modem using 5 1/4" floppies
When I was in high school we had an IBM something that had iron core memory and reel tape storage. Every so often you would have to blow the memory off, lol. I still can remember the replacement system had green screen monitors that faced straight up and had mirrors that would reflect half the image to one side and the other half to the other side so two people could work off of one monitor. That and a 8" floppy.
