There are several weird A3640/3660 add ons to add CPU RAM. Rev 0.1 of the Z3660 also did that. The problem is they disrupt Zorro III DMA. I no longer own any of those cards. BFG 9060 is a great card that is fully DMA capable. A period accurate 68060 card with 72 pin SIMMs is the Cyberstorm Mk...

Results are only marginally higher on 640x480, overall rating of 0.744

Sure- I had an A3660 card with a 64MB local ram module. So those do exist. Please see system info below for BFG9060 at 100MHz. Please note that resolution is 720p 8bit on graphics. Let me try 640x480 and see if graphics scores improve

I will do my best to get the Norton numbers- may you please send me the exact version you are using? Tests for different video modes aren’t really easy because the video mode and color depth is preset before starting shapeshifter. I expect the performance of your hack to be roughly...

Here is what my Amiga 4000 with a BFG9060 at 100 MHz (68060 Rev 6 overclocked) and ZZ9000 HDMI RTG card looks like using ShapeShifter. This uses the built in IDE for disk access- when I use my 4091 SCSI-2 card disk access is faster.

I am definitely very interested! Sorry about all the tariff trouble.

This is so cool.

The AOC 27b2h supports old Mac video input great. And 15khz too (even though the manual claims it doesn’t).

So, here is an Amiga 4000, CPU card is a BFG9060 with a real Revision 6 68060 at 100MHz and a ZZ9000 graphics card. First image is 8 bit 1080p using the ZZ9000 and second image is High Res Laced mode in monochrome. A 68060 at 100MHz is competitive with a PPC 601. Only downside is the 68060...

Slaton Computers on eBay is pretty good. I have their simms in my Quadra 700s and one of my SE/30s https://www.ebay.com/itm/176333431088

Sure, and the point I am making is that bus speed of the SE/30 is definitely not the problem since the IIvi and IIvx also have a 16 MHz bus. I am not trying one of their ROMS, but instead a IIci rom which ZZJ says works.

Yes, I just ordered one from GGlabs and asked them to write a IIci rom.

I don't think the bus speed is an issue, because this card allegedly works in the IIci, IIvi, and IIvx. I don't have a IIci ROM on hand. Any way I could buy one?

I don’t have the skill set to reverse engineer the ROM. I’m curious whether it might work with a IIci rom in an SE/30?

I searched far and wide for information on the Interware Booster CV 40 for the Mac IIci with the SE/30. I wasn't able to find much. I bought one from Japan and tested it with a Twinspark adapter. I can confirm that it does not work on SE/30.

I replaced the PSU with another unit and everything works fine now. What a pain though.

All readings are 0.0 V until the things springs to life a couple minutes after being turned on. Obviously a power supply issue- but what specifically?

Logic board was recapped by a previous owner. I'll need to leave the machine unplugged overnight to get the no chime scenario and check it tomorrow.

+5.00 V and +12.3 V read fine The -12.0 V gives me 0.0V Note that these readings are after it has booted up

I have an SE/30 that turns on very slowly. I don't mean the memory test, what I mean is that when I flip the switch it sometimes takes a full minute or two before the chime occurs. It is almost like a capacitor in the power supply or on the analog board needs to charge up or something. Is...
