niconiconi古董 #小霸王学习机 上电后毫无反应。我准备好万用表、示波器准备到处戳一戳，抓抓波形，结果发现是 DC 连接器 GND 焊盘铜箔断裂，10 秒飞线解决（搭接到了旁边的手柄接口焊盘，两者共用 copper pour）。但是这个手边仅有的古董黑白电视不能正常 VSYNC，只能看出有一个“小霸王”商标。这说明 CPU/PPU 能运行了，估计已经修好了，等待采集卡到来再试。#复古计算 #电子考古学 #小霸王
How to write code on your no-toolchain, no-documentation, and no-storage 1990s Chinese <del>totally-legal Famicom game console</del> educational home computer? No worries! You can find useful assembly routines on your own! Just dump the whole BASIC cartridge ROM via PEEK using this handy 6502 decoding script! 
The next section also gives you a typed-in ROM monitor. Absolutely disastrous learning experience. But you know it's truly only possible on a 6502 - the disassembler fits in just 4 pages. Steve Wozniak is going to either be amazed or have a heart attack if someone told him this was how 1990s home computers worked in China. #retrocomputing #小霸王学习机

Nina Kalinina@niconiconi I had no idea Subor could be programmed in machine codes🤯 thanks for sharing
@nina_kali_nina POKE some machine code into safe memory, and CALL the address (RE your BASIC first to know the ROM calls and safe zones). Just like the Commodore 64 and other 1980s home computers, except that there was almost no development tools or communities around it as few if any used it as a computer.
