Anyone got an A500 which is dragging? Just need that extra bit of speed? I did. There wasn't anything like LUCAS for the A500 and speedup cards were nearly non-existant for anything but Amiga 2000's out here in NZ. SO... I bought myself a 2630 card and installed it on my A500. It only requires one hardware modification on the main board - the 7Meg signal has to come out to the expansion socket. By making a small board which contains two 86 pin sockets I could plug the 2630 board in. Heaps faster!! More memory!! Only problem is it sits out in the open .. but I'm working on that.

Ahh....one little question: WHY? Besides the fun of the experiment, that is. There are 030 boards for the 500 now out. (and yes, they can use 32-bit memory). CSA makes one, and Imtronics is about to come out with one. >Aren't Amiga's Great Total Agreement here. >- Mark (tomlinson@elec.canterbury.ac.nz) >or try 64 3 3371531 and mail to MARK TOMLINSON > >What's a disclaimer anyway?

Glad to hear it works (it really should, the A500 edge connector is very much like the A2000 CPU slot). The only other big difference is that the A2630 takes over from the on-board CPU via the BOSS* signal, rather than BGACK*. For the purposes of an A500, BOSS* could be tied to BGACK* at the A500 edge connector. >- Mark (tomlinson@elec.canterbury.ac.nz) -- Dave Haynie Commodore-Amiga (Amiga 3000) "The Crew That Never Rests" {uunet|pyramid|rutgers}!cbmvax!daveh PLINK: hazy BIX: hazy Standing on the shoulders of giants leaves me cold -REM

I have a great Idea for an A500/30 or for that matter a new A500.
Take the mother board of the A3000/16.
Remove the expansion slots (to save space and money),
the hard drive (' '),
Keep the keyboard, mouse, one drive (preferably 1.44 meg)
SCSI port, paralell and serial ports.
Rework it so you still have the CPU expasion port
and put one Zorro III slot where the hard drive slot is.
And sell it with the 1950 monitor for about $1200.joseph@valnet.UUCP (Joseph P. Hillenburg) (10/18/90)
How about someone make something like this for the A500? Put the A2630 in a case and sell it to A500 owners as the A530, or better yet, stick an 030 on the motherboard at 33 mhz and have a PS/1 killer. (Might also want to stick a hard drive on the case of the card) -Joseph Hillenburg UUCP: ...iuvax!valnet!joseph ARPA: valnet!joseph@iuvax.cs.indiana.edu INET: joseph@valnet.UUCP

I like the Idea, except the part about changing the location of the slots. If you move the slots you are no longer using a 3000 motherboard which is a big problem because it would require a different production line to produce the board. The R&D cost would be very little but the cost of tooling up a new production line would not be. However I could see the posibility of producing a 3000/16 without the 68881, keep the slots (the board can't be that expensive), take out the hard drive and only keep 1 Meg of chip ram. and sell it for around 1500 (without the monitor) it would make a good replacement for the current 2000. Drop the price of the 2000 to the $800-$900 price range and we could all smile as all the talk about cheap Macs disappears from this newsgroup. -- -Dwight Hubbard, |-Kaneohe, HI -USENET: uunet.uu.net!easy!lron |-Genie: D.Hubbard1 lron@easy.hiam |-GT-Power: 029/004

Put it in a case just high enough for 2 - 3 1/2 " drives side by side. add as much memory as can be profitable (ie 2meg chip and 8 meg fast) and sell it to the workstation crowd. Oh yea put an ethernet card in the one zorro slot. Monty Saine
