![]() A 286 has lots of capabilities (approximately equivalent to a Mac LC) and a new system will run between $700-$1000. The rule of thumb is that if you need to run Windows, which Mac owners don’t really need to do, you should buy at least a 386SX. The older PC and XT clone models based on the 8088 chips are also dirt cheap, but their capabilities are extremely limited. Many used 286 computers are becoming available as their owners upgrade to 486s. In the PC platform, as the 486 increases its share, the prices of new 286 (the so-called "AT-class") and 386 computers drop by the month. Finally, you may want to buy another computer many used Apple IIs and old PCs are available. Another alternative is to adapt your Mac to run the other platform (whether it’s the Apple II or PC) and there are both hardware and software options to do this. With Stickybear, it’s uncertain whether a Mac version will come out in the near future, if at all. What alternatives are available if you want to use to a specific program that’s not currently available on the Mac platform? One course of action is to wait for the Mac version and encourage the publisher to "upgrade" its program to run on a Mac. Providing Stickybear for Jeff to use in a Macintosh household became a small project in itself. I saw the Stickybear Reading program in operation and was convinced that Jeff would be thrilled by it. However, the programs are fun and simple enough for a preschooler to run. I expect a Stickybear for Macintosh program would require significant graphical improvement. By today’s standards, the Stickybear programs have crude animation, and this may explain why Stickybear programs do not run directly on the Mac. Many of the titles are also available for the IBM PC platform and the Commodore 64. The Stickybear programs, which originated on the Apple II platform, recently celebrated their 10th anniversary. Weekly Reader Software offers about 25 programs that tutor very young children in basic educational concepts such as the alphabet, numbers, shapes, reading, music, grammar, writing, comprehension, typing and math. Stickybear is the featured character in a family of programs from Weekly Reader Software. One such program is the Stickybear reading program. 1646: Security-focused OS updates, Photos Workbench review, Mastodon client wishlist, Apple-related conferencesĪlthough I have used personal computers for over ten years, only recently did I become aware of the many children’s educational programs (my son Jeff is now 5).1647: Focus-caused notification issues, site-specific browser examples, virtualizing Windows on M-series Macs.#1648: iPhone passcode thefts, Center Cam improves webcam eye contact, APFS Uncertainty Principle.#1649: More LastPass breach details and 1Password switch, macOS screen saver problem, tvOS 16.3.3 fixes Siri Remote bug.#1650: Cloud storage changes for Box, Dropbox, Google Drive, and OneDrive quirky printing problem.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). I have an Archimedes (Sadly, currently not working as well as it should) that has a 32 bit wide data bus. 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. Thus DRAM, 4 bits wide, 64k cells of 4 bits wide. Now remember that second digit? This is where that becomes significant. (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. The rest of the numbers to the hyphen is the number of "cells" of memory there is. 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. All these numbers and terms aren't very clear about how much memory is stored in each chip, though.
