I want to buy a eeprom programmer,ebay is full of different models not sure which 1 to get.
I don't want something expensive and complex,since i will prolly use it,only in cases when i can't flash a bios using the software method.
Only thing i need is,to be able is to flash this 2 types of eeprom.
Here's my take on this:
I have 2 programmers: a USB-GQ3X and a TL866CS MiniPRO , both work fine with these old eproms but need an adapter for the PLCC one (the 1st pic)

Both are usb with english software.
The GQ-3X also needs a 12v/1A PSU in order to make good writes in (e)eproms.
The MiniPRO supports GAL chips - the GQ-3X no.
The GQ-3X supports writting 27C400 eproms (amiga kickstarts for example) the MiniPRO no.
If it's just for the occasional BIOS writting then get the MiniPRO, it's small and doesn't need any psu.
Search on eBay for them, there are tons available , just get the one you like best.
ps.
just don't expect these programmers to work wonders, support exotic chips or not having a bug or two (in new chips, the ancient ones we deal with are fine), there is a reason they cost only a small fraction of a good/pro programmer 🤣
TL866 would be my choice, it's cheap, it's usb and compatible with a lot of chips, but you will need some adapters.
Actually i have a old Willem Programmer, it's is very outdated but works ok.
Got a minipro as well from ebay. Great for reading old roms or writing the occasional replacement flash chips and you can get nice bundles on ebay with a bunch of converters if you'd need those.
