After attending the Apple new products show, I obtain the following information about new MacLC and MacIIsi. MacLC 16-MHz 68020 020 Direct Slot 2MB RAM (expandable to 10MB) 512k VRAM (optional) Stereo sound input and output Apple IIe card (optional) Build in 8-bit Video output 40 MB internal drive (Two drives configuration is only for high education) MacIIsi 20-MHz 68030 68882 (optional) 2MB RAM (expandable to 17MB RAM) MacIIsi NuBus Adapter Card or 030 Direct Slot Adapter Card (both of them include 68882 co-processor) Buil in 8-bit Video output Stereo soud input and output 40 or 80 MB internal drive Both machines come with superdrives.

Should read monaural input, stereo output. Sorry, Charlie. The input -is- stereo (check the plug), and Apple even provides an adaptor from the 3mm stereo jack to 2 RCA jacks.

The LC supports 8-bit video on the new 12-inch RGB monitor (512 x 384). You need the extra VRAM for 8-bit on the 12-inch monochrome monitor (640 x 480) or on the 13-inch RGB (640 x 480). Legacy of the LC's 4-bit intentions... A couple of folks at Apple confirmed that the switch-over on the Mac LC from 4-bit to 8-bit video is the reason for the late availability of the Mac LC (Q1 1991). According to one guy, they gave the LC to the folks at Camp Apple this summer and said, "Look, we're going to give you 4-bit color!" and the educators said, en masse, "Ick. We want 8-bit." So it seems that the prop about not wanting to release the LC until the Apple IIe card was ready is exactly that - prop. I want a IIsi anyways. <grin> -- +-----------------------------------------------------------------------------+ | Jim Gaynor - The Ohio State Univ. - IRCC - Facilities Mgmt. - OCES <whew!> | | Email [gaynor@hpuxa.ircc.ohio-state.edu], [gaynor@agvax2.ag.ohio-state.edu] | |_ "Don't tell me truth hurts, little girl; because it hurts like hell..." _|

The official Apple Computer Technical Specifications sheet reads: Sound input * Monaural 8-bit sound * Sound samples can be made at 22 or 11 kilohertz. * Macintosh Audio Compression Expansion (MACE) sound utility, supporting 3:1 or 6:1 compresssion, which allows approximately half an hour of sound to be stored on a sinble 40-megabyte hard disk. Sound generator * Monophonic 8-bit digital-analog conversion using 22-kilohertz sample rate--capable of supplying the same signal to both channels of sereo headphones or other stereo equipment through the sound jack. I.e. both input and output are mono only! Too bad ... Wolfgang N.

Legacy of the LC's 4-bit intentions... I'm DEFINITELY in the wrong here!! :^( Adding the VRAM gives 16 bit (some say 15, for 32000 colours, you work it out :) I should have checked this one. Also, a general warning to all those people who potentially want to run //e software on the LC. The first shippment of the 12" colour monitor will NOT support the scan rate of the //e requirements. This is fine as long as you'll never want to use it for //e s/w tho'. The "correct" version will ship when the //e card ships. Maybe they'll even put an apple on the monitor :) **My employers don't understand me, so I guess I'm on my own when I speak out** Norton Chia | I *think* my address is Micro Support | carsup@extro.ucc.su.OZ.AU *******************************************************************************
