From: Shawn F McKay <SHAWN@Mit-Ml> Is there any such thing as a pdp-11 emulator for 1: an ins8080a, or a Z80? Thanx -Shawn

I presume that this query has been previously submitted by others, o please answer by mail directly to me. If this is not well known, I'll be happy to summarize answers, and post them in net.micro. I would like advice on buying a home computer. The requirements are somewhat strange, but possibly not unusual: the system is to have a dual purpose - a first computer for my 8-year old son, and a terminal for me (to be used with our VAX system). As a terminal, I need good upper and lower case letters, 80 columns, and >=20 lines. The home computer should have decent graphics (for games), preferably color, should support the LOGO language (not necessarily all of it, but recursion is a must). Of course, any extra goodies are welcome. I also would like to keep price to a minimum. Thus, for example, I do not necessarily need a printer, although I will want to get one in the future. Similarly, memory (both core and disk) would be bought strictly to attain the capabilities above. Again, the possibility of expansion is probably a must. I know I could get all of this by, for example, getting a PC with two terminals (a green terminal and a color monitor), a modem, etc. for about 5K. I'm intersted in a much cheaper solution (at most half that much). A possible scheme would be to get a terminal and a modem for me, a color monitor and a cheapo machine (TI94, Commodore64 or similar) for him, and wait a couple of years to have something like a fat Sun become available for 2K. Still, it seems crazy that the best way is so dumb. Any comments? Suggestions of systems? Things to avoid? Thanks in advance. janos simon psuvax!simon

Do you have these two documents?
Radio Shack's Model 100 ROM Functions (700-2245) manual
May 1984 BYTE article "Inside the Model 100's ROM " By Brian Cameron
Perhaps they will help...

Two of us here at work are working on a paper, and the question came up as to what exactly is meant when someone says they are using a [microcomputer] disk drive using Winchester technology. Does "Winchester" imply microcomputer use only? Does it refer to the fact that the read/write head floats on a cushion of air rather than actually touching the medium as in a floppy? Does it refer to the recording/modulation techniques? Etc., etc., etc. If it is not too much trouble, could someone enlighten the two of us on what Winchester implies and what alternatives exist? Thanks in advance, Bud P.S., replies to my mailbox directly. If there is enough interest and response, I will condense and repost to the net.
