If I said that the Macintosh LC630 Developer's Note says I was mistaken(*); the IDE support software is documented starting from page 67 and it shows the new 68k "ATA Manager" implemented *alongside* the SCSI manager underneath the device manager, not nested underneath it. It does essentially...

Yes, and I looked that up, but it doesn't look like he found the actual PAL code to reference? (IE, he essentially did a black-box "functional recreation".) Granted we pretty much have plain-english explanations of what each PAL does so you could do the same with this; just having the original...

I just tripped over this thread, and I have to say it's really interesting that you're getting to the stage of integrating modifications into the board. I guess maybe I didn't read closely enough to see if you've already done so, but in the process of putting this together have you created a...

CFFL aging is definitely a concern, but FWIW the U3011 that’s been my daily driver for almost 10 years still looks fine. (My Apple Cinema 30” also looks surprisingly great, but I do know it’s lower mileage than the U3011 is.) I suspect it has a beefier lighting system than your average laptop.

If we were talking about Windows I might agree that 8GB is "fine" for "normal people", but for MacOS I just can't. My 16GB work laptop gets weird sometimes with just a web browser, Pycharm, and WebEx running. I mean, sure, if you're using your Mac as an expensive ChromeBook just to poke at the...

Frankly before spending any money I'd say priority #1 is finding someone with a modern enough Mac to drive it that'll let you borrow it for a few minutes to, yeah, see if this is worth your time at all. I will say that if the monitor works and is undamaged it may well outclass, well, at least...

No, you need a machine *new* enough to run the display. I'm reasonably sure that a brand-new ARM Mac can run that display with the Thunderbolt 2-to-3 adapter Apple sells for $50. (Which is kind of highway robbery, but that's neither here nor there.) The *floor* is 2011-era machines. So... From...

Googling I found this page that lists original and modified ROMs for various Radeon cards. The Mac cards seemed to consistently have 128k flash, the ‘Reduced’ firmwares are 64k. Unfortunately there doesn’t seem to be a ‘reduced’ ROM for the 7500. (7000, yes)...

If you Google up a review of the actual, official ATI Radeon 7000 Mac Edition you’ll see it has a PCB with an SVideo, DVI, and VGA port filling up the back panel; I remember the PC retail editions looking identical so I guess I’d probably prioritize that one, but alas I have no idea how much the...

Sure, I guess for $20 it’s probably a “fair” value for the functionality, most of my issue with it is the somewhat misleading ad copy. (Just come right out and say it’s a flashed card instead of the bogus graphics…) My frank evaluation would still be it’s probably *not* worth upgrading if OS 9...

FWIW, I’ve used 64GB SD cards in several different SD to PATA adapters and they see the whole capacity… which is possibly relevant because the chipset used in those devices was primarily designed for use in SD to CompactFlash adapters. If anyone is actually still making new direct SD to PCMCIA...

Maybe a little late to comment on this, but that listing is deeply suspicious, in so far as it seems to be implying it's some kind of official "Mac Edition" Radeon card. I would bet a million InternetBux (meaning, I dunno, a shiny new nickel) that it's actually a very, very low-end OEM PC card...

Thank you for the reference on this issue. I was pretty sure this was the case that the popular myth that the 2.8mhz shipping speed was all a grand conspiracy to "cripple" the machine in favor of the Macintosh was overblown, but didn't see a reference immediately that said definitively what CPU...

It's hard to imagine a world where building a "brand new" 65C816-based computer from whole cloth that didn't include some level of backwards compatibility would ever have made a lot of sense. Frankly the one selling point the chip has is its 6502-emulation mode; because of the architecture...

Pshaw, the Tandy 1000 rules. Of course I mostly say that because of all the utterly pointless work I did to hotrod the most ridiculous versions of them beyond recognition. Any 286 with a standard ISA slot can go to 15+ MB Extended (plus up to 32MB EMS Expanded) RAM with the right memory card...

Of course when you're talking about the Apple IIgs you can't overlook the fact that the original II architecture was so tightly integrated and non-extensible that backwards compatibility had to be implemented essentially by building the whole Trabant into your new racecar; they share the same...

Western Design Center was a small specialist design firm that completely concentrated on embedded systems. There was *nothing* like a serious roadmap for evolving the 65816 into a 32 bit architecture, and the 65816 was already a quirky obsolete-feeling oddball the day it was introduced. There is...

Per Trash's numeric comment above, the Macintosh II used the 68020, not the 68000, at 16mhz, so, no, an 8mhz 65816 would not be faster than the Mac II. More importantly, a faster IIgs, unless you made a raft of other changes, would still not be a directly comparable machine to the Macintosh in a...

Just for laughs you really should give one of those knockoff-Cherry-Clone mechanical keyboards that Amazon is full of a try. If you don't mind slightly weird round keycaps I can personally vouch for this one. (I posted about it a few months ago after getting a pair of them for a ridiculous...

Wow, the proposal actually exists. It's kind of amusing, re: the discussion about page faults in the other thread, that item #1 on the "Additions and Enhancements" list is: Anyway... Skimming through this the details of the "CPU board" are fascinating. The "video" section of it has a full 128K...
