Well, I bought an A-3000 with CD-Rom drive, grafic tablet and 1080 monitor for 100 Euro from a local online auction 3 weeks ago.
That was no real bargain ( although I think the price was ok - I have seen A-3000s go for more without any additional things ), but the really GREAT thing was that the seller had also sold an A-1000, and there was an A-1000 add-on, called GOLEM
This GOLEM is a third party product for the A-1000 which is an accelerator and memory expansion for up to 4MB ( or even 8MB ?? ). It is very hard to find !
But the seller thought it was something for the A-3000 and so I got the GOLEM and also an HD Floppy drive expansion for the A-1000
