I’ll have a look on old magazine cds, they tended to include those kinds of updates. I used a version of MRJ from around that time.

Hold-And-Modify. 6 planes are used (or maybe it’s organised as packed nybbles). The top 2 bits control Color changes for the bottom 4 bits. 00 means select a palette colour. 01 means change Red, 10 for Green, 11 for blue. So you get 12-bit colour for 6bpp at the loss of colour resolution. It’s...

Or DOM modules. https://www.ebay.co.uk/itm/293327691438 But note, although the pinout is IDE, it's a socket and a mirror image. A simple PCB with a header can fix this.

That's -14ºC, for those unused to international temperature standards! It's 7ºF (for people into ForeignHeight units ;-) ). Hey @killvore : impressed by the old-school DYMO label print! Those things are such fun!

We have a Canon MF641C Laser Printer, which prints wirelessly from our MacBook Airs (M2 and Intel 2019) and Mac mini 2012. Haven't tried it with my MacBook C2D 2008, but I can try it. There's a driver that goes back to Mac OS X 10.5, so it should work (with my MBc2d.. and it might also work...

10.3.9 will feel great compared with 10.2.x. I only use versions of Mac OS X I actually have copies for, or the version that came with the Mac, but you might be happy with downloading Mac OS X 10.4. For my (Dad's) 1GHz G4 iMac 15", I run 10.4. Because Apple seemed to do tock/tick style OS...

Aaah, but does it do HAM mode?

Very nice! As people have noted, the keyboard is a Mac 128K/512K keyboard; the Mac Plus one had a numeric keypad. Having said that, I prefer the 65% type keyboard, I wish Apple had kept it as the standard format rather than going through the extended keyboard fetish in order to copy PCs. The...

A P5200 is just a P6200 with more swivel. :ROFLMAO: @David Cook I think the app as it currently is (or how you've modified it) is worth testing on the P6200 and P630 to see what the results are, if it's no inconvenience to get them out. Given that DRAM is so much slower than cache, I'm not yet...

Of course, didn't think of that, though normally I do use --x or ++x for that reason. It's odd though, because surely a sequence like: move.l regACount,0(a0) subs.l #1,regACount move.l regACount,4(a0) subs.l #1,regACount move.l regACount,8(a0) subs.l #1,regACount could be generated by a...

@Phipli , @zigzagjoe , @noglin , [at] anyone else with a 630/5200/6200 or comparable era Mac. I've updated the tests to include RMW tests, which operate on whole words to add the current loop countdown to a given word. I think that's as valid as operating on bytes. I removed the 4 Sets test...

And finally, the 68K version! These are the results I get for that: For 68K version running on my PB1400, I get slower results. TestTicks/LoopTicksRemCountBandwidth (MB/s) L13640287155626710886467108864*4/1048576/((87+(36402-15562)/36402)/60)=175MB/s I've just included the normal L1...

For your delight, I've updated the very crude app to support writing directly to the framebuffer. I did it by dereferencing the Pixmap handle from the CGrafPtr for screenbits. This version of the app should therefore work with a P6200 and if recompiled, for a P630...

Hi folks, OK, I've written the test application. It's not very big. Source code and application are included. The results take a bit of interpreting. My PB1400c is a 603e Mac (as we all know). So, it has a 4-way x 16kB, Write-back L1 Cache. It also has a 128kB L2, Write-Through cache. So, I...

Yves Lempereur wrote MacASM, an integrated editor/macro assembler. It was the first self-hosted Mac Development environment and it's tiny, about 25kB. Its integrated environment is un-Mac, instead like editing BASIC on a Commodore 64, complete with line numbers, a BASIC style command line. OTOH...

It's a real privilege to hear from you. You might regret the number of questions this prompts me to ask, but here goes: Firstly, are you saying that the 'C' compiler was Hippo 'C' or Consulair (or something else)? Secondly, why wouldn't it have been possible to develop with MDS or MacASM as they...

I'm certainly making some assumptions, because I too, don't have a P5200/6200 and I'm only an embedded firmware engineer. But I think maybe I wasn't clear enough in my earlier comment too. Other people have suggested there were extra wait states because they figured the '040 bus ran at 33MHz...
