I retired by #tl866 -- the socket's too loose. Somehow, the new #t48 that replaced it lacks the same charm.

It's no longer a 1980s-looking beige box, it's black with rounded curves and a needlessly blue LED, and it's finickier (doesn't like being on the USB 2.0 under-desk hub with the HID devices)

I suppose it's mostly nostalgia-- the 866 is where I built my most successful hobby project (a CH375/6 option ROM).

Still, do I need strong feelings about ROM programmers? #vintagecomputing

New video! I'm showing two (and a half) ways of getting the TL866 EPROM programmer to work in Linux.

Progress!
I've got a basic #emulator working for my #Pat80 #homebrew #zilog #z80 #computer !
This should ease the os development as I can test the changes without having to: remove the #eeprom from the computer (without bending the pins), program it in the #TL866 programmer, place it again on the computer (aligning pins correctly), test, notice it's not working and have no idea why, start debugging with the logic probe on the #address and #data pins, swear in arcane languages... 😅

If you want to program 16-bit 27C400 ROMs like #Kickstart ROMs or #vintagemac ROMs, the #TL866-II programmer is out of production and all sellers sell the #XgecuT48 instead. Even if they claim that it's the TL866-II, it isn't and you'll most likely get a black T48 instead.

The T48 is not compatible with the adapters sold for the TL866-II, it's wired differently and the socket is the other way around.

Luckily now there is an adapter for the T48 also:

There is effort on open source #firmware for the #TL866 programmer, which looks quite capable.
I am considering getting one of them, but they cost about €60 currently.
