Peripheral Technology PT68K4
Peripheral Technology PT68K2/PT68K4 family
2011-01-03 Skeleton driver.
2013-09-30 Connected to a terminal
2014-01-03 Connect real DUARTs, FDC, and TimeKeeper. Settings now save properly, floppies can be read.
2014-01-19 ISA bus and compatible cards, PC keyboard support, speaker support
2014-09-20 Add PT68K2, add save states, we have a working SK*DOS disk!
This has the appearance of a PC, including pc power supply, slots, etc
on a conventional pc-like motherboard and case.
Some pics: http://www.wormfood.net/old_computers/
Source code and manuals for the HUMBUG BIOS and SK*DOS are at:
http://www.users.cloud9.net/~stark/sources.html
Usage:
Start up and press Enter as prompted. Type he to see a command list, or fd to boot from the
first floppy drive.
The stock NVRAM configures PT68k2 for 2 DSDD 5.25" drives, and PT68k4 for 2 DSHD 5.25" drives.
Chips:
68230 Parallel Interface/Timer @ FE0081
68681 DUART/Timer (x2) @ FE0001 and FE0041

TODO: 68230 device
This system and SK*DOS don't like our ISA WDXT-GEN emulation so HDD installs are not currently possible.
