Vxl 30

[dreamcast270mhz]

So, I got a VXL30 and an A500 on the way. The VXL30 is missing the CPU, FPU and 68k and CHip number 5 according to the manual. Whats chip #5? And how do you install it into an A500 that will have KS 3.1 in it?

Hi,

@dreamcast270mhz,

Ok, it has been 10 years since I had a VXL30, but mine was a 68030 @ 40mhz, they also made them in 25 mhz, 30mhz versions. It is a card and just plugs into the 68000 socket, I can't remember if it had a red wire on it that connected to a 5 volt power source. I will try to look in my old records and see if I made a copy of anything, since I usually sent the manuals and disks with the product when I sell it. I did at one time have a huge copy of all materal that I had bought, but moving from Florida to Pennsyltucky lost a lot of my computer stuff, or it got packed in some other box.

No wire gets connected to a +5v power source. Gets all its power straight from the 68k socket. The wire you might be thinking of gets soldered from one of the PAL chips to a point on the RAM daughtercard that was necessary in some early revisions if you had a DMA capable SCSI card in your system.

The chip that's missing is probably a PAL, so good luck finding a replacement  

Here's a link to some more info:

I have a VXL 30, as per above. But as I've found useless without the memory daughterboard. Have traveled many a road to find the RAM board, but either it's too expensive or the deal is not worth it.

Hi Dreamcast270,

So, I got a VXL30 and an A500 on the way. The VXL30 is missing the CPU, FPU and 68k and CHip number 5 according to the manual. Whats chip #5? And how do you install it into an A500 that will have KS 3.1 in it?

Looking at the hires photo at:

Can you identify where U5 is? (The legend is a bit hard to read).

Looks to me like the chip in the bottom right hand corner of the main board, in which case it would be a 74F126?

You may have trouble finding one of those, the 74F125 (with negative buffer enables) is much more common.
An LS part may suffice, and are still easily available:

Manuals regarding install can be found at the amiga resource site.

Hope this helps,

The U22 is 5, sorry I didnt' mean U5, I meant what microbiotics manual said is 5.

Update: Got the card to-day. It has a leg on the bottom broken but otherwise as described. Now I need to find an 030 and some other stuff.
