3M silentwriter model 1483?

I think I remember the 3M flavor having the latter name. I played with one of them back in 1983 or 1984. That one had a keyboard connected to a thermal printer by some sort of cord (they were separate boxes), and I think an RJ11 phone jack for a POTS line. As I recall it was an ASCII terminal plus modem with a memory buffer that could be used for offline composition, and it came to us recommended as a tool for composing and sending Telexes via Western Union's Easylink service. (We sent it back and made an HP150 do the job.) I don't remember if it could be made to do other codes than ASCII. More recently (early 1990s), I've seen one with a little CRT (again in a separate box) used as a Telex terminal, but didn't inquire to find out how it was connected or what was on the other end of the connection. -Frank McConnell

Call for final Elf99 design input

by dcoward＠pressstart.com

First I just want to say that I'm still looking for 'copies' of two RCA publications: MPM-232 Operator Manual for the RCA COSMAC DOS Development System (CDS III) CDP18S007 MPM-233 Hardware Reference Manual for the RCA COSMAC DOS Development System (CDS III) CDP18S007 If you have one or both or know where to order these manuals, please let me know. O.K. I said: >I think there is a source code listing in Paul Moews book on >Elf interpreters. I dug my copy out and yes there is source listings. Paul took RCA's CHIP-8 interpreter and modified it for the ELF. In this book ("Programs for the COSMAC ELF: Interpreters"), he starts with a subset interpreter that has 10 CHIP-8 instructions and is intended to run on a 256 byte Basic ELF. Then he lists the full Elf CHIP-8 interpreter with all 30 instructions. This is intended for a 4K Super Elf with 1861 video, but it can run on a 1 1/4K Elf. "It is also possible to use CHIP-8 in the 1 1/4K ELF's described in the articles in Popular Electronics, but to do so is very tedious unless the switches are replaced with a latched decoded keyboard." He also demonstrates with listings, how to extend the CHIP-8 instruction set. I can send you a copy of this book, it's only 31 pages. I also have one of his other books called "Programs for the COSMAC ELF: Music and Games". ----------------------------------------------------------- Fun Fact of the Day Did you know that a windowing graphical user interface was available for S-100 bus in 1979?

FSOT: IBM 4869 external 5 1/4" floppy drive

by bill_r＠inetnebr.com

I've got a pile of these somewhere. If anyone can use them, I'll sell them for $10 each plus shipping. I also have some of the PS/2 internal 3.5"-to-external-5.25" drive adapters, too. >I used to assume that too-until I found a unit that someone had replaced the >floppy drive in the unit with a Teac drive.

Recent Finds & Thoughts

All Dolby B seems to do, is increase the level of high frequencies when the recording is made. Then when played back, the Dolby NR reduced the level of high frequencies back to what it should be (hence also reducing the background hiss). So recording with Dolby off and playing back wilth Dolby on will serve to reduce the level of high frequencies; not what you want with computer tapes. Recording with Dolby on and playing back with Dolby off should probably work; high frequencies will be louder than normal. >For PET (and family) tapes a C2N would probably make a good cassette >machine for playing it initially, since it does some of the signal >restoration itself. Better might be to use a high-end tape deck (maybe a three-head unit) since the transport should give less wow & flutter. -- Mark
