[Simh] System/1

The DoD system running our nuclear arsenal off floppy disks is an IBM System/1, their 1970's "answer" to the popularity of DEC and DG minicomputers. When they released it, some IBM flack said that the System/1 "legitimized" the minicomputer market. This led to a famous (albeit never published)

Re: [Simh] Question about card readers.

I wonder whether OP is referring to a situation where there is a 96 character line, such as a programming language statement, and that the first 80 characters would be on a card and then the remaining 16 characters would be on the next card but with a continuation character in, say, column 1. I

Re: [Simh] Question about card readers.

I once saw a IBM punch card that was small as a playing card, had three rows of 8? Punches, and held more than 80 characters. The operators actually used them as playing cards. Sent from my Galaxy Tab® A Original message From: Robert Armstrong Date: 05/26/2016

Re: [Simh] Question about card readers.

There is a proposed card reader library (not mine) in the GitHub repository, which you could try. On the 1401, the handling is as follows: 1. The card reader buffer is 2*CBUFSIZE + 1, where CBUFSIZE is an internal SimH constant for buffer size. The buffer is zeroed before a read. 2. The card
