bc5dcedf1d MicroVAX1: Remove DMA devices which weren't supported on MicroVAX I 
Removed TQ (TMSCP), TS (TSV11) and VH (DHV11) devices from this
simulator since these devices were never supported in release MicroVAX I
configurations.

Lacking a scatter/gather map, DMA devices needed to be written to
perform DMA into contigous buffers in low memory and then copy data
to user space buffers.  The MSCP protocol devices had specific support to
do scatter/gather transfers as part of the protocol.  The RL01/RL02 device
driver was modified to perform the appropriate buffer moves most likely
to prove the customer option to adjust their drivers actually worked.  In
any case, boot support for RL01/RL02 disks does not exist.

0fd7a9e5ef 3B2: Fix for diagnostics timer hang 
Under certain circumstances, the timer resolution in the Version 3
could become coarse enough that very short timer intervals would lead
to an infinite loop of bus errors when running timer firmware
diagnostics.

796a3e1abc AltairZ80: Adds SOL20 and VDM1 devices 
This PR adds support for the Processor Technology VDM-1 display adapter and Sol-20 computer system. The VDM-1 was integrated into the Sol-20 but has been separated out into its own device.

This PR adds the following devices to the AltairZ80 simulator:

VDM1 - Processor Technology VDM-1 display adapter
SOL20 - Processor Technology SOL20 with SOLOS ROMs
SOL20K - SOL20 Keyboard (callback from VDM1)
SOL20T - SOL20 Tape (reads/writes cassette file images)
SOL20S - SOL20 Serial Port (TMXR capable)
SOL20P - SOL20 Printer Port (TMXR capable)

498aedefd5 sigma: Correct recognition of pending DP seek interrupt. 
This corrects an error that caused SIO reject when SIO occured before
a pending seek interrupt on a different device.
 - Move the interrupt pending test from sigma_io.c into each device.
 - Make the sigma_dp.c test a special case that looks for pending
   seek interrupts.
