  1. Well, the IIe doesn't have any kind of special control jack for the cassette interface, so you should hypothetically be able to use any audio source that can both record and play back, reel-to-reel included. From what I read, the highest frequency part of the signal is only ~2.2 KHz, so 7.5 IPS should be more than responsive enough for accurate capture, and you could probably go slower.
  2. Yes, it was the same Ensoniq DOC chip used in the Mirage sampler and ESQ-1 and SQ-80 synthesizers (though those paired it with analog filters, whereas the IIgs just outputs the sample data plain.)
  3. Never have used a Soundscape. I do have an old Ensoniq OPUS card I've been meaning to plug into something, but I haven't gotten around to it yet. I do like those old soundcards (back when MIDI wasn't just that same damn cheapo mangled Sound Canvas patch set!)
  4. I've never had a USB keyboard or mouse fail to work under OS9, but on the Blue & White G3 I had to use an ADB keyboard with OpenFirmware as it wouldn't recognize the (non-Apple) USB keyboard I was using.
  5. Hell, even the laptop P4s were terrible in the thermal department. The P4m laptop I used to own got hot enough that when the power supply went nova and actually melted the plastic tip on the plug in the process, I didn't actually notice for about ten minutes.
  6. If it's "illusive" I hope you didn't pay much for it...
  7. Yeah, that looks a lot like a SOG signal that the monitor isn't filtering out of the picture.
  8. Have you tried picking it up and dropping it?
  9. How does QuickDraw acceleration factor in? I can't imagine that Apple with their "do everything in software" philosophy implemented that on the Quadras' built-in video, did they?
  10. I don't know about the exact percentages, but yes, memory access time is a major bottleneck on the 68000, particularly as A. it's primarily a 32-bit processor, but only has a 16-bit bus, so all 32-bit memory accesses take two cycles, and B. it has no cache on-chip, so any time it needs to access memory it's stuck waiting for however long it takes on the particular system. There are mitigating factors, but it's definitely a significant factor.

    Ooh, jealous. If you ever get bored with the programming or MIDI books, I'll happily offer them a good home
  12. Even if we take that at face value (yes, there are window-manager themes that replicate the OS9 look very nicely, but good luck getting anything else to look all that Mac-like,) the key point is that it's not how classic Mac OS looks, it's how it feels. It's a pleasant user experience not just because it looks nice (which it does,) but because it behaves in an intuitive and, most importantly, consistent way. The same cannot be said of Linux (where each of the three or four standard UI toolkits has its own standard for user interaction, each application using them has its own set of deviances,
  13. Quite a bit, yes. Aside from a couple oddities like the division between address and data registers, it basically looks like a 32-bit PDP-11 as designed by someone who hadn't seen the VAX.
  14. Heh, I'd like to try my hand at a homebrew CPU sometime, but I'd need to brush up on my low-level electronics knowledge a good deal first...
  15. Yeah, but those components cost money, and if compact Mac users were already content with 1bpp video, why spend the extra $0.x/unit?
  16. Yeah, that's the Micron Xceed mentioned earlier in the thread.
  17. Say you bumped it up from 1bpp (black & white) to 2bpp (four shades of gray, same as the Powerbook 150.) That doubles the amount of memory required for the framebuffer from ~21KB to ~43KB - considering that the machine originally shipped with 1MB, that's not really a huge amount. Double it again to 85.5KB and you get 16 shades of gray, and still only use ~1/12th the amount of RAM in the minimal system configuration. Now, granted, the SE/30 actually has separate video RAM and they'd need to put in 128KB simply to use available parts, but that's still really not a lot. In fact, if everym
  18. I've got a 50MHz '030 in my Amiga, and it's pretty zippy, but not by as much as you'd think - I presume because it only has 1KB total L1 cache (512B instruction/512B data.) I don't know what's on this card, but my observation is that if you're not going to go to an '040, you really want some amount of L2 cache on the accelerator.
  19. I believe the IIGS uses Mac-style mini-DIN serial, correct? If it's much like the Mac internally you could probably use a Mac serial-to-MIDI breakout box, since the UARTs there were flexible enough to talk at MIDI rates. No idea what the selection of IIGS MIDI software looks like, though.
  20. As a general rule, the answer to "should I get a mid-'90s CD console that didn't come from Sony, Sega, or NEC?" is "not unless you really like tedious, poorly-acted FMV games." (Or, if it's the CD-i, "not unless you want to pay way too much money to experience some of the funniest things made by man.") And with the Pippin specifically, can't you run those titles on a Mac anyway?
  21. Yep, this is normal. PCs, Macs, even my PDP-11 slowed waaay down in its boot time when I kicked it up to the full 4MB.
  22. If the address bus is (effectively) only 24-bit, does it really matter if the ROM is 32-bit clean?
  23. Man, all I find when I go digging in the woods is dead bodies.
