Are you sure this was your setup in 1991? I find that slightly hard to believe. I bought a 486DX2/66 with 8 MB ram and a 245 MB IDE drive in 1993 and this was an incredible amount back then. The computer itself was also hideously expensive, mind you (I had a lót of money to burn, back then).
This makes claiming to own an Amiga 3000 with 16 MB ram and a 540 MB scsi(!) drive in 1991, slightly unrealistic, especially as owning a cd-burner in 1991 would be impossible: CDRW came on the market in 1997. And a cd-changer in 1991? Nah. I bought a double speed CD-ROM drive in 1993, maybe 1994 for EUR 340(!).
Anyway, my Amiga-setup in 1991:
- the omnipresent A500, ofcourse. Rev 5 motherboard, KS 1.2;
- an A1084 monitor (no 'S');
- a KCS Power PC Board;
- a MacroSystem Evolution SCSI-controller (bootable with KS1.2);
- an external SCSI-case with a Quantum 80 MB SCSI harddrive;
- a Star LC24-10 dot-matrix printer;
- a Tornado 2400 modem;
- an external 2 MB fastram expansion (I forgot which one);
- several joysticks.
Good setup back then. It remained like this until being replaced by a 486 in 1993.
Yes,i' m sure i had a 3000 then,and i had a cd burner by late 91-the CDR standard was introduced in 88'-notice i said cd burner(cdr and not cdrw),the cdrom in 83' ,cd changers early 90's-Mine was used on some SUN server i think before i got it.they had started upgrading to 18disc+ units if memory serves . Previous to this i had the A2000 with a 1x cdrom in late 90..bought it new and it cost me a freaking fortune.this stuff was available in the usa pretty early. just had to sell a arm,leg and kidney to afford it- i think i paid $540 for the 540MB scsi quantum hd-i remember remarking it being a buck a meg.The 3000 would burn a good disc every time while multitasking .Most 486's could produce coasters if you touched the mouse at the time.Even back then if you knew where to look finding surplus scsi stuff was not hard,and alot cheaper.The 3k then felt top of the line with the 3640 in it and 16MB Static column ram and it seemed there was nothing it couldn't do well(yes,contrary to what misinformation you read on the net SCZIPS work with the 3640 ).Everything seemed to happen 2 years ahead of europe i noticed. I picked up most all my amiga's used from people upgrading,there was always a deal to be had and at a fraction of what new ones cost. I also repaired alot of stuff and upgraded cheaply that way.It all started with the 1541 i bought from a kid in 83 for $75 with a dead chip in it-6522 i think,i fixed it for $15 and had a floppy for the c64 for under $100,when they cost a fortune then.
I knew alot of people in industry then and scsi surplus was easy to get and every so often a bargain.Don't blame me if you were behind the times or if scsi wasn't common in europe as here.You can be a typical consumer who looks at and pays retail and assumes whats on the shelf is all that is available or you can be a insider and dig for good deals.
