Release 3 of PDP10 simulators

Richard Cornwell

I am pleased to announce the addition of the KS10 to the DEC PDP10
simulators. With this addition all of the DEC PDP10 computers are now
supported. Including the KA10, KI10, KL10A and KL10B and KS10.

KL10 has support for ITS and will run TOPS 10 7 series monitors or TOPS 20
monitors. The KL10 will also run TOPS 10 6.03, along with the KA and
KI. The KS10 will run Tops 10 7 series, Tops 20 V4.1 and ITS.

This release also includes some patches to improve the performance of
the simulator, along with fixing some outstanding bugs. If there are
any additional devices that users would like to see please let me

The PDP10 simultors support:
* RC10 RD10/RM10
* RP10 RP01/RP02/RP03
* RH10/RH20/RH11 RP04/RP06/RP07 (RP07 not supported under 6.03).
* RH10/RH20 RS04
* System Concepts DC-10 IBM 2314

* TM10A or B
* RH10/RH20/RH11 TM03/TU16
* TD10 Dectape

Paper Tape
* Punch
* Reader

* DC10E terminal mux.
* Morton tty Mux for ITS.
* Knight Kludge mux for ITS.
* Terminals on KL10 Front End.
* DZ11 on KS10.

* LP10 Line printer.
* LP20 Line printer on KL10 Front End, and KS10.

* IMP networking support for ITS and TENEX.
* NIA20 networking support for KL10.
* CH10 networking support for ITS.
* CH11 networking support for ITS (KS10).
* DUP11 networking support for KS10.
* KMC11 networking support for KS10.

* 340 Display Station support.
* III Display support for WAITS.
* Optional support for PDP6 devices (standard if WAITS included).

The RP10 supports boot (actual hardware did not), by reading in Blocks 4-7
and transfering to the loaded value. RC10, RH10, TM10 support readin mode.

The PDP6 simulator supports.
* 270 Disk
* 561 Magnetic tape.
* 551 Dectape.
* 340 Display station.
* 630 terminal mux.

RP01-RP07 type disks support KLH10 DBD9 and DLD9 disk format. So images created
with KLH10 can be used without issue.

I would like to thank Bob Supnik, Lars Brinkhoff, Mark Pizzolato, Pascal Parent,
Bruce Baumgart, Angelo Papenhoff, Bryan Jenson, Cory Smelosky, Phile Budne,
R. Voorhorst, Rich Alderson, Stephen Jones, Al Kossow, and The Living Computerr
Museum. All these helped in various ways to get these simulators working. Either
via testing, contributing devices, or providing documentation or software.
