[cctalk] Fortran question for Unix System-5 r3

Fortran question for Unix System-5 r3. When executing fortran programs requiring "input" the screen will show a blank screen. After entering input anyway the program completes under Unix System V *r3*. When the same program is compiled under Unix System V *r1* it works as expected. The user

I have seen lots of laptop drives that would fit a 50 pin connector that is about 2mm pitch  Looking at the back of the drive from the left there are 44 pins in a group then 2 pins missing and the remaining 4 are for selecting master and slave. Paul. On 2023-03-26 4:33 p.m., Steve Lewis via

Weren't many slimline CD-ROM/DVD drives 50 pin ATA? I've got one such in an HP ePC (P3) box. https://www.bixmart.com/Internal-Slim-50-Pin-PATA-DVD-Writer-Drive--8X-Double-Layer-_p_34.html --Chuck

[cctalk] Re: ATA-3 50-pin IDE

50 pin is usually SCSI I've never heard of an Ata standard that did that... 44 pin laptop was just 40 pin + power (and maybe cable select, I forget). There was an 80 pin cable standard, but that used 40 pin headers and special connectors to do primary/secondary better/faster especially for

[cctalk] ATA-3 50-pin IDE

Is anyone familiar with the 50-pin IDE interface, which I think is called ATA-3? It is from around 1997-2002. Normally IDE is 40-pin, or in laptops might be a 44-pin. But in a COMPAQ Presario 1220, I've come across its hard drive that is using this 50-pin interface (two rows of 25-pin that are
