Ersatz-11 V2.2 (PDP-11 emulator)

A new version of Ersatz-11 is now available. V2.2 of the freeware Demo version may be downloaded from www.dbit.com as usual, and commercial users with current update subscriptions (or ones that expired only recently) will be mailed update disks tomorrow. Probably the most interesting addition for hobby users is the new VT11 vector graphic display processor emulation. Yes, it runs the Lunar Lander game. It also works nicely with the GT ON command in older versions of RT-11, as well as EDIT.SAV's scroller mode. A copy of Jack Burness's Lunar Lander game which is all set up to run under the emulator is available at: http://www.dbit.com/pub/e11/lunar/ Other changes which are visible even in the Demo version include the SET CPU FIS and SET CPU EAE options, the Interlan NI1010A/NI2010A Ethernet emulation, the built-in mini-assembler, and the overhauled manual. The full commercial V2.2 release includes the above changes, plus it adds a new DR11C/DRV11 emulation using TLC's DCI-1300 PCI board, which is pin-compatible with the DR11C/DRV11. Also there's a new DH11/DM11BB emulation, the RocketPort driver can handle ISA cards (used to be PCI only), the SCSI disk driver can partition disks on any boundary, multiple serial ports can be attached to the same emulated PDP-11 port (with duplicate output and merged input), and the Q/Unibus adapter drivers allow subsetting of the I/O page so you can have multiple adapters, to get a dual Q/Unibus system, or two identical busses for distributing heavy DMA loads. The new DMA-friendly BCI-2004 bus adapter is supported in addition to the older BCI-2003/2103 and UPG-3600 boards. Also, the DEQNA emulation now supports booting over the network. Acrobat files containing the manuals for all three versions (Demo, Lite, full) of E11 are available on the "Links" page on www.dbit.com. The Demo version's manual .PDF file is also part of the self-extracting INSTALL.EXE archive, plus it's available as a PostScript file at: ftp://ftp.dbit.com/pub/e11/e11demo.ps The E11/Linux port is nearing completion and will be released this summer, however it will probably only be available in a commercial version.
