Re: TU-58 support under Unix

My speculation would be that TU58 did not add anything of value or convenience to these systems. I used Ultrix-11, V7M, Venix in this era.  My recollection is that in most cases to build these systems and patch them, you needed regular access  to 800/1600 BPI tape. Given this relatively standa

Hi I'm restoring a PDP-8/a with the help of some friends. The CPU is now passing the MAINDECs I've thrown at it. The memory is a modern semiconductor board my friend Anders Sandahl made. This machine is pieced together from several others and the limited function panel I got does not match t

TU-58 support wouldn't need to be in the kernel, it could easily run in user space. Perhaps someone had written an application in user-space to dump TU-58 tapes. Aaron. Bill Gunshannon via cctalk writes: > Here's a question for someone who has been around long enough to > remember. > > Why did

TU-58 support under Unix

2019-02-03 Thread Bill Gunshannon via cctalk
Here's a question for someone who has been around long enough to remember. Why did none of the available PDP-11 Unixes support the TU-58? I have looked at Ultrix-11, V7M and BSD 2.11 (didn't try 2.9 but I suspect if it isn't in 2.11 it wasn't in 2.9) and none of them had support for the TU-58. S
