So I called the shop I got the parts from and it appears that the pins my generic PN2222 are reverse of yours: 736 2n 3903   Looking at the flat side   E left B middle C right I will give this a try again tomorrow with the transistor aligned opposite of what I had.  Wish me luck.

Here is my progress on this.  On Sunday I was able to solder the components I have to the protoboard that arrived. Purple wire is +5v_SB that goes from the PS to the MB pin 10.  I stripped some insulation from the middle and attached the 1K resistor. The other end of the 1K attaches to the left...

What card is plugged into your socketed SE/30 Daystar in the top photo? Although it doesn't work in a SE/30, the Daystar Turbo 601's control panel allows it to boot to 030 or the 601. I wonder if you could boot this insanity: That is a IIsi cache card with the 601 in the pass through and an...

Thanks for this. The board is going to have an appointment with the caps doctor. Great catch on my bad. I have only 1K caps as I was going from the diagram with the black background, not yours. I will grab some 10K 1/4 watt resistors from Vetco if they are open today.

I am thinking this may be the case as I had the connections as you described.  I will try to solder it up tomorrow and see how that goes.  THx

FWIW, I swapped back to the IIci and the without capacitor setup and it did not work there.

Some good progress made today and I am now paused with a question. Here is my PN2222 (generic version) I don't have a breadboard so here is how the PN2222 is connected to my SeaSonic PS: Leftmost leg...Purple +5v is connected to the PS and the motherboard (2 complete wires from 2 different...

@JDW this is the ROM on my NuBus Radius PrecisionColor 8-Xj: It lists v1.5 however there are later versions. Are you saying you have this NuBus card that has had its RAM removed?

@tact where did you get ROM chip for your Radius card?  I need one for my NuBus Radius PrecisionColor 8-Xj discussed here. THs

Thanks for this guys. Vetco is between work and home so I will swing by and replace the 1/2 with 1/4.  I think all of their 1K resistors were $0.29/each. Hopefully the protoboard will be waiting for me when I get home.

Yay, the site is back. @superjer2000 I went shopping and have 2 of the PN2222's and when it came time for the 1K resistors, the guy behind the counter asked what wattage... What wattage did you use for this?  The guy thought they looked like 1/2 watt so I left with 4 of those.  The shop didn't...

Hi @superjer2000, I looked at pin diagrams after posting this. I had assumed PN2222 only had 2 pins and it was the 74LS04.  I think I get how this goes together with the 3 pins on the PN2222 and I will update that diagram after some sleep.   You mentioned that this powers the IIci from the...

Hey @superjer2000 I am about to go shopping and make a couple of these and I tried to stitch everything together and I have a question for you on your final assembly. Could you take a look at what this and LMK if I interpreted your connections correctly and LMK what that center connection is...

Unfortunately it does not. 1 appears on the ENvision monitor but nothing on the Samsung connected to the Radius card.

Makes sense. Thank you.

Hi All, I had a bit of time last weekend to try some suggestions from the seller of these cards wrt the Radius and that was to try with an adapter that had the dip switches. The video upload issue postponed this post... When I boot to with the Radius connected to my NEC multisync VGA adapter...

Hi All, I have an Asante NuBus card discussed here that does not play nicely with the 2 D Link 10/100 hubs that I have.  These hubs work fine with my Asante IIsi/SE/30 cards. To get the Nubus card recognized I need to short the pins on the card after boot sequence has started. The Nubus card...

No cache does indeed take some of that shine off.

This auction completed today...here is its description: Vintage Interware Booster 30-SE50F 68030/50MHz CPU upgrade card for Macintosh SE/30   Manufactured in 1993 tested and works great.  Includes a 68030 running at 50MHz and a 68882 FPU running at 50MHz.  Also includes a vertical facing PDS...

Are you going to stereo speaker?  Isn't the output from the SE/30 mono?
