Re: AT IBM Industrial's for sale (Ebay warning)

I've not laid hands on any yet, I ordered up 5 for stock. I do know from the friend I mentioned that the bus is a bit odd, but only that it is faster in some timing than regular AT. But regular ISA cards did fit. These were in toll booths running printers, so may have been loud, no data on

I have contact with a motivated seller who has a huge bunch of IBM Industrial systems to sell. They are Model 7587, and were used on the Kansas Turnpike to run printers and the like (maybe other stuff). he has about 50 of the things and has them listed for $15 bucks, but is motivated to sell any

RE: EMACS folly

Hi, Lars, I actually met someone once who tried to implement an interpreter for TECO code in Emacs Lisp, in order to load EMACS.:EJ and run it, just for the hack value. I don't know whether he ever completed the project. :-) We have a VAX-11/780-5 (a 780 field upgraded to a 785) running VMS 7.3.

Re: Odd "endianness" [was Re: RE: Base 64 posts to the list]

Not meaning to throw things to far off but on my NC4000 machine( 16 bit ), I found ByteSwap useful enough that I had it hard wired. I have an old computer that was intended to do FFTs. It has a complete bit order swap, MSB to LSB, instruction. All interesting. Dwight

Brother TC-600 Terminal/Typewriter

Hi, recently I acquired a 1980s Typewriter, a Brother TC-600. While not exactly a classic computer, this typewriter was often used as a low cost printing terminal (aka teletype). It has a serial interface and I was able to connect it to my PC. I can SEND characters and text files to a terminal
