IIsi and Daystar 040

G'day,

Currently I'm recapping my old IIsi mobo after the video stopped working. Here's hoping it's just caps. Anyway, I've got a Daystar 33mhz 040 accel that I want to use in it. Yes I know these things traditionally should be pimping out SE/30's rah rah..okay. But I gave my SE/30 away to a friend years ago who loved it dearly.

So.. as passe as it is, I'd like to get this working in he IIsi. If I understand this correctly I need to scare up an adpater. I do have an Asante network card (has a 68882 slot in it) so my questions are:

1) What adapters are available to me, and where can I find one?

2) Can I still use the network card?

The network card is pretty interesting and seems to have a slot/adapter on it. I'm dead curious as to whether this thing can work with the Daystar, but am cautious to plug it in and find out.

Anyway, still re-capping and cleaning up the board and the corroded tracks so it'll be a while.

Any suggestions? Can someone set me straight on what/where/how ? Thanks :)

Regards,

Al

Hi Al,

you need the Daystar-specific IIsi adapter, which has two slots, one for a NUBUS card and the other for the accelerator itself.  With a bit of searching you should be able to obtain one.  Be wary though that the IIsi has a weak power supply, so coupling accelerator + network card + max RAM + fast HD might bring it to its knees faster than you think; consider adding an external PSU if you really max out your machine.

G'day JB,

..quickie, are you the JB from #perth? :) If so.. the base machine came from you about 2001. It's travelled a lot since then. I'm back in perth. If so.. what a blast of retroleum!

Thanks for the info. The PSU worries me actually. I'm planning to recap it also. I'll try and find an adapter. Ebay doesn't seem to have anything or I'm not searching for the correct terms. Will keep you updated.

The Asante card I have (Can't remember where I sourced it from.. it's lost to memory) .. goes straight into the PDS slot and has another slot on it. I can't use that can I?

Regards,

Al

Owning the 50HMz(?or is it 40MHz?) version of that card in my IIci, I say that it is wise to get the PSU Recapped.

I do not know how rare is the IIsi Adapter but I would figure that is quite rare. You will also need the software for it (a control panel & extension to turn it on/off and Apple's 040 Cache control panel, which came with it). It is best to turn off the 040 Cache off as there is a lot of older 68K Software that crash in using it.

As I remember correctly, you will need System 7.1 as a minimum for it, System 7.5.5 would be best. Thus you will need to max your RAM for the machine to handle that OS as well.

Since the adapter gives you a NuBUS Slot, you will need a "new" NuBUS Ethernet card for it. Your Asante PDS Ethernet card will no longer work with that adapter.

Well.. some good news! I finished recapping the IIsi today and bridging the black-tracks from some high-resolution images of the motherboard I found online.

Feed it a CRT and hard drive, powered it up and was greeted by a nice beeptone and a moment later it commenced booting and went straight to the desktop! Win! :)

Quite exciting!

Next on the hit-list is the Quadra 605 that had that rotten maxell battery that vomited spooge down the board and pds slot!

Rather excited.

Oh.. and I hear fireworks for my mac's rebirth! .. doh! it's only new years revellers! .. heh good timing!

Apple Color Composite IIe monitor.  I had a new-old-stock analog board but it wouldn't power on.  So I ended up swapping the flyback transformer from the NOS board to my old board.  I'm surprised it worked.

The monitor is 10x quieter than before.  It was almost whisper quiet, but if you walk to the rear of the monitor, you can hear it.  So I think my next step is to buy some sound dampening foam and stuff it in there.  There's plenty of room in the rear bucket.

Now I've run into the problem that of all the software titles in the world, my absolutely favorite game in the universe isn't compatible with my Apple II accelerator.  Sigh.

still..baby steps. :) You'll get it working.

I should do something and get my IIgs recapped and running. Might look into it once the IIci and the IIsi are both happy.
