I have setup a spreadsheet to benchmark Mac computers on Quake: https://docs.google.com/spreadsheets/d/1ndaq6qB-cMrCBbtbENK5MjTWr4g-nnw6yWjLqYM2ARM/edit?usp=sharing I would be very interested in seeing what FPS you would get on your mac.

I'll write down a few notes on what I did to get pretty decent video capture as it wasn't obvious. 1. DB15 -> VGA. This is well documented. 2. active VGA to HDMI adapter. I used "FOINNEX VGA to HDMI Converter Adapter with Audio 1080P" (https://www.amazon.es/dp/B072NCTBVP?) 3. HDMI capture card...

I did some work to get a 80w micropsu to run a ”portable 5200” (bluescsi and db15 to hdmi capture so the screen is on my laptop). However, I would want my 5200 with CRT to work again. Its original PSU said bzzzzzzt when I plugged it - as if it was shorted. I am thinking best would probably be...

VRAM on performa 5200 is DRAM, 60ns, 1mb, on a 32 bit bus. I get about 21.8MB/s when I write 320x240x2 bytes (takes about 0.5M cycles, 0.5M/75 MHZ = 0.0067 => 320*240*2/0.0067/1024/102) (this is with ideal scenario of unrolled 64-bit writes of constant data). Two estimates for how much vram is...

I would like to be able to travel with a 6200/5200. And so I am thinking if one could just take the logic board, and have e.g. 3d printed case to slot it in into, which hooks its pins up to to a small PSU, and IDE cable (+CF card adapter), and a mac-vga port.[[ I saw this cool hack which has...

I've the 603e user manual, with supplements for 603, and that should contain all the differences between 603e and 603. Regardless, I would like to have the original 603 user manual :) Is there anyone who might have it as pdf (my web search has not been fruitful), or perhaps would be willing to...

Are there (reliable?) benchmarks that compare these CPU:s or these machines? I think most likely the PPC 603 performed quite a bit better than a 486DX2/66 P24D. Against the Pentium 75 Mhz I'm less sure. In real world use cases the P75 would likely be quite a bit faster due to the bus and due...

There is detailed information about L1 (as it is part of the CPU), i.e. N-Way (on 603 it is 2-way), cache policies, that it is LRU, what bits from physical address are the tag, and what bits in the EA/PA are the index, etc. As L2 is not part of the CPU, information about it is unlikely to be...

I have a 5200, I'm thinking of getting a 68k desktop (not all-in-one), and if it was compatible with the 5200 logic board I could swap that board in for video capturing the 5200 (without having to buy the external monitor cable and get a 68k as a bonus). But I am not sure which 68k desktops can...

I want to record the screen from my Macintosh Performa 5200. For that I need the mirror-cable. I've been able to video capture my PowerBook 5300 with a chain of PB5300 -> MacDB -> VGA -> HDMI -> USB HDMI Capture Card -> MacBook Air, and planning to do the same (maybe there are better ways?). I...

I'm making a demo (demoscene) for my beloved 5200. It is not the fastest machine and there is no 320x240 mode, so one must upscale in software which steals quite a bit of cycles. The Apple TV Tuner Card is 320x240 and it up-scales to 640x480 (in hardware, I'm quite sure). Perhaps there is...
