Title: Viper 520CD
Post by: MichaelP on March 07, 2013, 07:37:29 AM
I've been sorting through all my old computer stuff and came across my A500 accelerator. It is a Viper 520CD internal accelerator.

020 based, math co-pro, 8MB ram, Kickstart 3.0 and has IDE on board.

i'll probably never use it again and was wondering if it is worth selling.

I definitely is. It will likely fetch you a nice amount of money. Those are highly sought after.

I'm in Scotland. Going to set it up later and see if it still works. I think i remember it being a 68020 @ 16mhz. I'll let you know how I get on with it.

I'm spending too much time messing about with my old Amiga stuff. Forgot I had as much.

Amiga 500 - 0.5mb chip ram, 0.5mb fast
Amiga 500 - 1mb chip ram, 1mb fast
Amiga 1500 - ? chip ram, GVP scsi adapter with 8mb fast, 1GB HD, CD-Rom
Amiga 1200HD - Boxed, 8 MB fast, still looks new.
Amiga Rom Kernel Manuals.

More boxes to go through. Also have Commodore 128, MPS-801 printer.

Having way too much fun. Going to be up all night i think. :lol:

Viper 520 runs a 020@28 mhz, used to have one, sold long time ago.

Got mixed up.

Heads swimming with all this stuff.

Mine is a Viper 520-33-CD, so I'm assuming it is 33Mhz

A bit hard to tell from the pic, does anybody with first-hand knowledge know if this will fit with the Indivision ECS?

*bump* for my last post. I'm considering bidding but not if it won't fit with the Indivision. Just curious if anyone knows, thanks! :)

@thread

Just curious.

What does that make one of these (http://www.bigbookofamigahardware.com/bboah/product.aspx?id=64) worth with 68882 and mega-memory board populated with 2 Meg? (like new)

I have that board and it is a fast, stable and nice board. The 33MHz 68020 gives about 5500 dhrystones which is more than some 68030 A500 accelerators. The on-board 32 bits ROM is a nice feature compared to the 16 bits original ROM. There is room to fit your hard-drive on the board. I regret that it won't work with any DMA device one the side port such as the A570 or A590.

However, it will not fit with an Indivision ECS because the Viper520 covers the Denise. It might fit underneath with one or more CPU risers, but then you will loose the upper shield and may be unable to close the A500 case. It would require serious modding to take the Denise socket elsewhere with a ribbon and put the Indivision elsewhere. You could also sacrifice the Denise itself (not putting it back on top of the Indivision) but then no more output from the DB23 port or component RCA.

Probably whatever the market is willing to pay.  $250-$300?  People in Europe might tell you less, because stuff isn't as rare as it is in North America.  Like hen's teeth!

Why, you have one for sale?  ;)
