* various devices used by hp9k_3xx.cpp: initialized some variables to fix ↵ Ivan Vangelista2020-06-061-0/+3

* Heavily improved emulation of GRiD Compass 1101 (#6599) usernameak2020-04-261-0/+3
| | | | | | | | | | | | | | | | | Changes: - added known dump checksums of 1101 BIOS - high-level emulation of GPIB disk devices - partial implementation of DMA (currently ignores ACCRQ so devices must have zero latency in order for it to work) - serial is now properly memory-mapped - modem stub in order to make system properly ignore modem device - it now boots without any patches and debug scripts - merged #6597 (needed in order to make disk devices work) Still not implemented: - RTC/MACHINE_ID - modem - has problems with multiple disk devices working simultaneously (possibly BIOS bug because this BIOS had some problems with that on real device)
* tms9914: added SR & PP FSMs, typo fixed fulivi2020-04-261-22/+119

* devcb.cpp: syntactic sugar for constructing/resolving arrays of callbacks (nw) Vas Crabb2020-02-051-12/+2
| | | | | Saves a lot of typing { *this }, { *this }... Could be applied in more places, I just did a few devices to demonstrate it.
* (nw) Clean up the mess on master Vas Crabb2019-03-261-2/+2
| | | | | | | | | | | | | This effectively reverts b380514764cf857469bae61c11143a19f79a74c5 and c24473ddff715ecec2e258a6eb38960cf8c8e98e, restoring the state at 598cd5227223c3b04ca31f0dbc1981256d9ea3ff. Before pushing, please check that what you're about to push is sane. Check your local commit log and ensure there isn't anything out-of-place before pushing to mainline. When things like this happen, it wastes everyone's time. I really don't need this in a week when real work™ is busting my balls and I'm behind where I want to be with preparing for MAME release.

* tms9914: Rename read/write handlers and remove superfluous arguments (nw) AJR2019-02-181-2/+2

* tms9914: extend logging & disable DEBUG output in default configuration (nw) Sven Schnelle2018-10-211-2/+15
| | | | | | | Add some debugging to print the standard GPIB commands like MLA/MTA/MSA. This makes reading a log much easier. While at it, disable LOG_GENERAL as that logs every byte transferred which fills up error.log.
* hp_9k_3xx: enable save state support (nw) Sven Schnelle2018-10-111-0/+49
|
* tms9914: latch EOI flag until next byte is sent Sven Schnelle2018-10-101-8/+15
| | | | | | hp9000/300 sends FEOI directly after the data register write, before the byte is actually transmitted. This leads to the current byte being sent out with EOI set, instead of the last one.
* tms9914: fixed handling of GTS aux command. fulivi2018-05-101-6/+10

* tms9914: added RL state machine. Minor fixes. It now passes HP9000/340 POST. fulivi2018-05-081-7/+38

* tms9914: added methods to read ACCRQ & CONT output lines fulivi2018-05-041-1/+26

* tms9914: improved emulation. HPIB test of IPC diagb ROM now passes. fulivi2018-05-021-3/+15
