Sadly, I had no Amiga in 1991. I purchased my first Amiga, an A500, in 1992.
In 1991 my rig consisted of a JiffyDOS'd C128 with 64k VDP RAM, a 1581, and two 1571s. It had a 1764 REU I expanded to 256kb (or 512kb, I can't remember which at the moment,) and an Emerson 2400bps external modem using a TTL-to-RS232 converter I built from a magazine schematic using a chopped up IEEE cable.
Sadly, I don't have a pic of this. I do, however, have a pic of my meager start-up 64C and an Enhancer 2000. I also had the WarpDrive fast-loader cartridge. This pic also captures the last gasp of my involvement with the TI-99/4A and a PEB I had borrowed from a guy in town, which I used to convert some of my old games to work on disk instead of tape, and my transition from learning TMS-9900 assembly to hacking away 6502 with a vengeance.
And I'm not sure where that phone is, now, but I would love to find it.
