Originally posted by titmowse the first one i played on and that made me fall in love with computers was the Amiga 2000. the first one i owned was an IBM PS2.
the amiga's were the best thing out there in it's time. Damn, fuckall for ram, fuckall for system bus, fuckall for pwoer really, but those boxes could churn out graphics no pc or mac could touch. All thanks to the video toaster. Altho the video toaster was designed for only the 4000 series you could get equaly impressive graphics from an A1201 (A1200 + 1.5 megabyte 'chip' memory upgrade installed) and upgrading the workbench rom. the a2000 was really a "pc" version of the a500 that was designed to have the guts of the a500 but have expandability such as with built in ram and hdd and zoro slotts. If anyone has seen the a2000 vs the a500 you know what I mean. The 500 and 200o were same thing really except the a500 had to have a litle breakout box that attached to its side to hold up to 16 megs of ram and a 512 meg max hard drive.

In high school our computers only were able to do mathematical calculations. There weren't hard drives yet. The program code was stored on these strips.
My first computer was an Apple IIC
CPU 65C02
CPU speed 1.4 Mhz
Motherboard RAM 128 k
Number of Sockets n/a
ROM 32 k
Data Path 8 bit
Bus Speed 1.4 Mhz
Serial Ports 2
Floppy internal Disk II 143 k (5 1/4"), floppy port
Display 40/80 column text, 4 bit color at 40x48, 3 bit color at 260x192, 2 bit color at 560x192, standard 9" green monochrome monitor
SIG TOO BIG! Maximum 120x60 button and no more than 3 text lines of DEFAULT SIZE and COLOR. Unless your sig is for a GFY top banner sponsor, then you may use a 624x80 instead of a 120x60.
ah the a1200, great graphics on that sonovabitch for what it was. A friend of mine was usning it up until 3 years ago until he fried his monitor. Now he cant find one to replace it. If i could find a monitor for it I would take it off his hands
