I'm in the market for an add on memory board for my Amiga 500 (I finally got my B&W camera for the Digiview, so I need some memory to do hi-res color). Ideally, I would like an internal upgrade, which comes with no memory, so that I can add my own chips (which are abundant at my house). Memory chips supported would preferably be 41256 or 411000 DRAMs. Almost ideally, would be a hard disk interface with a memory option. The requirement I have for a hard disk interface is that it be DMA, and support SCSI devices, and the memory would also have to be unpopulated. (I think GVP makes what I am looking for, but it comes with a hard disk, which is not what I want.) As you can probably tell, I want to get into this with as little outlay as possible, since I can add my own SCSI drives and memory that I have sitting around. Mail me comments, and I'll summarize for the net if there is sufficient interest and information. Thanks! noid@oliveb.olivetti.com sun!oliveb!noid

Has anybody had experience with the Pacific Peripherals subsystem for the A-500? I've seen it below $200 mail-order. The internal A500 boards are NOT cheap, even unpopulated, and you WILL need to get a new power supply to power the critters. Not to mention that I see problems with DMA SCSI controllers... Seems to me that a Zorro II subsystem for the A500 is the way to go. A2000 disk controllers and RAM cards are dirt cheap compared to their A500 equivalent. Buying just a slap-on-the-side SCSI controller is less expensive than buying a subsystem and an A-2000 SCSI controller, but when you add up the cost of both the slap-on-the-side SCSI controller and the internal expansion stuff... it's close, real close, to the expansion chassis + A2000 cards alternative (especially if you choose a SCSI controller with RAM on-board, such as, hmm, one of the GVP Impact controllers). -- Eric Lee Green P.O.
