efc8f9db2b Fix for TC08 dectape support: Forgot that the TC08 uses three-cycle databreak; 
addresses 7754 and 7755 are used to support this.  Moved RKSYS code out of this
area to avoid conflict.

77866b7b65 Initial fixes for TC08 code -- hardcoded addresses in dectape code cause RK05 swap 
code to be overwritten.  These have been corrected but something is still touching
address 7754 in field 0 when it should not.

18d8363c9a TS8 assembly broken with EAE enabled, bootstrap routine for RK05 was too large. 
Ensmallened code in BOOT.

a31b083cdd Removing files unrelated to tss-8 (Brad's vhdl, cpu sim, etc.). Adding clean LCM disk image with software loaded. 
Small cleanup to ts8.pal.

38191a07c6 Fixed free core map for RKSYS-related blocks. Hopefully. 
Cleaned up some naming, removed some TODOs.

134c021505 Minor fix, disabling echoing by monitor in LISP. 2019-11-23 23:19:30 -08:00
Josh Dersch
47fba92a6c Ported LISP-8 (DECUS-8-102A-PB) to TSS-8 (fixed entrypoint, added restart address). 2019-11-23 17:39:12 -08:00
Josh Dersch
858519f4bf Added RK8E bootstrap to ts8.pal. This allows quick rebooting (assuming core is intact) 
from address 3053 in field 0.  (Ensure AC, IF, and DF are clear beforehand.)

d5b8016c4f Ported CHEKMO-II to TSS/8. 
Updated disk image:  Filesystem extended to 1MW, cleaned up with new accounts.

2ddaf0d205 Added patch to maker.c; updates INIT for a 50Hz clock (as used on the M8330). 2019-11-20 19:43:58 -08:00
Frank
20f6e172cb Modified filesystem size to the maximum permissable by the TSS/8 filesystem code, approx. 1mw. 
Updated system to include TC08 and high-speed papertape reader/punch.

3987c3da16 Added small RK05 bootstrap (to avoid needing to load INIT in via papertape every time). This loads INIT from track 
2 of the RK05 and starts it.

Updated params.pal to reflect a larger disk size (400 tracks), and updated maker.c to make it easier to update
the login message.

ab1b026866 Filesystem disk reads/writes are now retryable on error. Retrying tested via instrumented code. 
Fixed (?) tabs.  Ugh, tabs.

a726d29efd Minor updates to ts8.pal; we now explicitly check for rk8e disk address overflow (should never happen). 2019-11-17 13:35:20 -08:00
Frank
90c4ec6687 Fixed issue with track # translation to RK8E disk address for one of the two swap paths; this was causing 
the bizarre behavior when TSS/8 ran out of core.  Some minor cleanup.

ea7b705dc0 Fix in RK05 SWAP routines (incorrect return from calls to SWPIO), this fixes the random delay when exiting 
from programs.

A couple of small bits of code cleanup.

System still falls over when it starts actually swapping out fields (e.g. more jobs running than core).

f25d0c95be Interim fix for disk address calculation in RKGO0, I forgot about that whole "link bit" thing and the "rotate" 
thing with RTL.  Whoops.  BASIC runs a lot better now that it's not reading garbage into memory.

Things generally seem to be working.

9dce55ea3a Many tiny fixes. TSS/8 now runs from RK05! Long delay on program exit; suspect hung device. 2019-11-14 18:16:12 -08:00
Josh Dersch
0664d7d2f4 Further debugging and refinement. Discovered that the free core table in INIT clobbers parts of field 1; 
this occurs on a clean tss8.2 build as well.  Stubbed out all but the first core free (which frees the
majority of unused space in field 1), needs to be more deeply investigated.

5d99e1bfee Initial prep for fixing DSG0 to use RK05. Mostly notes, a few added comments. 2019-11-08 17:40:35 -08:00
Josh Dersch
8495481b64 Latest changes. INIT now works; loads MONITOR into memory and executes it. 
Swapping appears to work.  Filesystem routines stubbed out.

e2226765af Adding LCM mods to run TSS/8 entirely off of RK05. Initial checkin. 2019-11-07 17:04:43 -08:00
