Sorting out the zx81 library set on z88dk
I've been recently working on the less common versions of the LAMBDA 8300 ROMs, and hopefully I made everything more flexible by adding two new subtypes ("mono" for the v1 ROM and "cac3" for the CAC-3 and the NF300). While woring on it I noticed that I had never ported some of the ZX81 functions, su...

Programmer's toolkit
I described this technique in the ZX81 section already, this is the derived version for the Lambda clones. NOTE: THIS IS AN EARLIER, BUGGY VERSION THE ENTRY LOCATIONS WILL PROBABLY CHANGE For V1 (older) ROM, add 1 to all the listed values (19110 -> 19111) ============================================...

Re: Different ROMs for Lambda 8300
I was counting on you :lol: Well I've almost finished, I think I spotted the equivalent entries also for interfacing C to BASIC (and vice-versa), I'm testing it on the different ROMs but most of the code looks valid also on the later ROM version with more differences from the ZX81. printf ("Basic le...
Re: ELIZA
Now extended to CAC-3 / NF300 and V1 ROM.

Re: DSTAR on all the Lambda models
As a bouns, I think that the horse animation is somewhat satisfactory if you have a slow computer.
Type any key repeatedly to hit the horse and make it run faster.

Re: Word Processor: Tasword for Lambda 8300
you can still load the programs on EO, but you csn't rely on flash loading To be able to quickly load the .p program EightyOne taps the ROM and reacts when the emulated program counter register reaches the tape routine. The location is hardcoded in the emulator and works with the known ROM types onl...

Re: CHR$128 Font Bank Manager
The games get way cooler with a font replacement ! I really like those retrofits improving an original program leaving the original code untouched (the CHROMA interface really brought it to the extreme), Some year ago I introduced an "SVG vector graphics" capture option on the FUSE emulator: you fir...

DSTAR on all the Lambda models
I reworked the 'dstar.c' example we have in the zx81 section of the z88dk examples. It is now capable of producing valid versions for all the Lambda ROMS... at least I hope so ! Could anybody try this stuff on the real hardware ? If so, could you check it on different TV sets? I have a last resort t...

Re: Different ROMs for Lambda 8300
I chose to go for three different ROM types only, the CAC-3 and NF300 are so close. At the moment I'm ignoring the zx81 retrofits The first thing to do is to fix the interrupt/video handler. I noticed that the early monochrome ROM uses a different register (and a different order for the push/pop seq...

Re: Different ROMs for Lambda 8300
So to recap we have those different ROMS:
Lambda 8300 v1 (LAM10061.BIN)
Lambda 8300 v2 (I believe EO simply names it "lambda.rom")
cac-3.rom (8EEC1EC6-cac-3.rom)
NF300.ROM (F8BBA9D8-NF300.ROM)
ZX81 compatible ROM for Lambda 8300
Am I missing sometthing ?
Lambda 8300 v1 (LAM10061.BIN)

cac-3.rom (8EEC1EC6-cac-3.rom)
