More A1000 tinkering

[jupo42]

Hello, all...

Last year, I started a project to upgrade an A1000 as far as I could without changing the motherboard. I put it on hold because of life but want to finish it before this year's CommVEx.

So far, I have...

Rejuvenator, which lets me have:
- ECS chipset & 1MB chip ram
- OS 3.1 ROM
- AGA2000 FlickerFixer
AdSpeed/IDE 14MHz 68010

On order, I have an IDE->CF adaptor and a cheap CF card. If all goes well, that will arrive next week. Then I can mount the CF "drive" inside the case and still keep the internal floppy. Will post some photos then (really, this time).

Currently, it boots up off a 300MB IDE drive and works flawlessly. SysInfo clocks it at near A1200 speed, not bad.

My next dilemma is RAM. There isn't any room for the CPU piggyback board I have, plus the AdSpeed/IDE might screw up compatibility anyway. I used to have a Dataflyer SCSI controller that had an 8MB RAM expansion, but both of those cards are toast.

Anyone have any 4-8MB side-slot RAM expansions sitting around? Any other thoughts or suggestions for upgrades?

Interessting machine, do you have photos from?

Here´s my GB A1000: http://www.a1k.org/forum/showthread.php?t=11088

That sounds like one helluva A1000 setup! I've got the parts necessary to make a Zorro II adapter for it if you have that much trouble finding an external RAM card (which you shouldn't). Be kinda ugly without an enclosure though, but am in the middle of building one for my own use. Oh and my 2mb external Minimegs is NOT for sale. That has got to be the 'cutest' little ram expansions I've ever seen  :-)

If it helps broaden your search any, I have a SupraRAM 500RX with 8mb (intended for a500s) that works fine on my A1000.  Mine isn't for sale (I painted it black, anyway,) but they pop up on eBay every so often, and they don't look all that bad on an A1000 due to their size.  Passthrough, too.

hi just being a pain not realated to you qwestion
but see you listed a aga2000 flicker fixer fixer card
where did you get the cable to go from ega to vga so can hook to pc monitor l having trouble finding on here

[jupo42]

@actung:

I got the cable by pure dumb luck.

A couple years ago, someone was throwing away a storage unit full of vintage Macs, and I took as many as I could fit into my car - including several crates of cables. When I ran across that cable, I thought maybe I could use it on an ancient Epson I have or something, and tossed it back into the box.

When I got the AGA2000, I pulled it out and prayed it wasn't going to short circuit anything... I had no clue if the pinouts were right.

But it works.

Okay, photos, round 1. Click for bigger pics, though the resolution on my camera sucks, sorry.

Under the hood:


The AdSpeed/IDE fits very snugly under the floppy, but it does clear:
