But it needs to read it 32 bits at a time, so there are 32 of them, for a grand total of 4MB of RAM. It has an absolute sea of 411024 RAM on the motherboard (The nomenclature is slightly different because it was sourced by a different manufacturer, but it's equivelent). The Apple IIGS features the Macintosh design with resolution and color similar to the Commodore Amiga and Stari ST and remains compatible with earlier Apple II models. The easiest route would be to find a IIGS or contact a local Mac (or Apple II) user group for help. Scan converters are out there, or at least they used to be back when there was demand for such a thing. It is a 16-bit personal computer produced by Apple Computer, Inc. The IIGS monitor operates at 15.75KHz, while a computers VGA output is 31KHz. I have an Archimedes (Sadly, currently not working as well as it should) that has a 32 bit wide data bus. The Apple IIGS is the fifth and most powerful of the Apple II computer family. Now, not all systems have 8 bit datapaths. The difference? Whereas 41256 needs eight chips to make an 8 bit datapath, 4464 only needed 2 chips to to make the full 8 bit datapath. Thus each of these was also 32 kilobyes wide. Best Early Education Program The New Talking StickyBear Alphabet (Apple IIGS), Weekly Reader Software/Optimum Resource. To support TCP/IP you will need a commercial bridge product, either software. Thus DRAM, 4 bits wide, 64k cells of 4 bits wide. need to run with the IIgs, and the free but unsupported LocalTalkbridge software from Apple will run on most macs. Now remember that second digit? This is where that becomes significant. Apple IIGS: Stickybear Talking Alphabet (revisited) 1,883 views Like Dislike Save lucas boy 1.31K subscribers Notice Age-restricted video (requested by uploader) Try it free and save. (Confused yet? Took me YEARS to be able to read these). So this chip is 256k x 1 bit wide, thus 32 kilobytes of potential storage. Now this is tricky, because you need to multiply the number of "bits wide" the RAM is by this number to get the actual bits, and then by 1024, because it's a measurement of kilocells. I didnt put it in the Printer port because that slot is set to 'Your Card' and I have a MicroDrive in it. Maybe it is because I have the cable plugged into the Printer Port on my Classic and had my IIGS in the modem port. I thought AppleTalk would work on the Modem port on the IIGS. The rest of the numbers to the hyphen is the number of "cells" of memory there is. It worked fine after I plugged it into the printer port. I have systems using 44 series RAM (Commodore 64 later models) so they're 4 bits wide and you can read or write a 4 bit nibble per chip. You can only read / write 1 pit per chip. I suspect there's 8 but I've never seen it. The second digit is how many "bits wide" the chip is. 4 for DRAM, 6 for SRAM, so this is a DRAM chip. The first digit is whether it's SRAM or DRAM. There's a standard (Gotta love standards. The OS by default configures this as 15 stereo channels and uses the remaining two channels as interrupt counters the IIGS is therefore often described as a 15-channel machine.All these numbers and terms aren't very clear about how much memory is stored in each chip, though. The IIGS provides a 32-channel wavetable Ensoniq sound chip, which uses 64kb for samples. The IIGS includes many programs that can aid kids with their reading, writing and spelling. However it is subject to a number of deficiencies: there is a single buffer for video only - double buffering is not supported - and it supports neither hardware scrolling nor hardware sprites and as all writes into video memory clock the CPU down to 1Mhz these are expensive to perform in software. There is also some support for 'fill mode', in which colour 0 means "repeat the last non-zero colour", designed to aid in fast single-colour fills.Ĭolours are selected from a 12-bit RGB 4,096 colour palette the IIGS therefore has the same total colour range as its contemporaries the Commodore Amiga, the Atari STE and the Acorn Archimedes. Each line may use any of 16 palettes, making a total of 256 colours on screen without raster-linked palette changes. In addition to RGB emulations of the existing Apple II artefact composite video modes, the IIgs adds 320x200 and 640x200 RGB colour modes the former in various combinations of 16 colours per line and the latter at 4 colours per line (including a hardware dithering mode that acts a little like 16 colours per line). It runs natively at 2.8Mhz but will slow down to ~1Mhz when in classic Apple II emulation mode or when writing to video memory. The central processor is a 65816, a backwards-compatible 16-bit update to the 6502 that was also used in the Super Nintendo.
