Re: Star Micronics NX1000 series printer



Today I found Star Micronics NX1000 series technical manuals on manualslib website. [...]
It said that it uses m50734sp processor (6502-based microcontroller) with 64K EPROM chip. [...]
Does anyone have a copy of M50734SP user manuals? [...]

Thanks,
Tim

That's MELPS 740 family. And it was not ...

Re: Paper plots of CSG 6502 derivatives

Plots are very nice, but what about the things found at the (former) MOS office ?

All these tapes - if they had design files, it would be really pity if they were trashed.

Quick test with "label: $ADDR" formatted files - works nice.

Thanks for adding this :)

Re: WFDis - 6502/65C02 interactive disassembler

I have been using WFDis recently (looking into the TIB PLC DD-01 ROM) and I really like it, helps a lot when analysing a binary.
Background info: TIB PLC DD-01 is a cartridge for C64 with a 37c65 (improved uPD765) FDC controller + 3.5 inch FDD drive.

There is a little thing I miss though - for a ...

Re: How did MOS design and photomask technology evolve?

Well, just to follow this up a little bit. I recently bought a 6569R5 wafer from someone on ebay.

This reminds me of the (ex) GMT/MOS office cleanup done last year - some wafers were found there, as well as lots of backup tapes and some rotten Pets (C65s were scrapped at the beginning of the ...

Jim Brain succeeded in dumping code from these microcontrollers.)

Yes, I know this was done - I am on the CBM Hackers mailing list as well.

I need to figure out where do I have all of these piggyback R6500/1-s, I guess last time I ...

Re: stm6502 -- a 6502 simulator for the STM32F4Discovery boa

Well... It's time to buy the Discovery board finally ;)

BTW - There is a new C64 CPU accelerator project with a Cortex M0 running a 6502 emulator. Now it gives you 10x speedup. But this is in assembly, not in C/C++ ;)
