Best (cheap) universal programmer
« on: February 26, 2020, 09:30:33 pm »
As the old notebook with the parallel port had decided to not power on anymore, i need to replace the old willem programmer for something more "modern".
I do pic, 24c eeproms, dallas rtc/ram chips, old eproms, and eventually flash chips (like for example the bga153).
I was searching also over here and seem that the tl866ii (as the cs/a are out of production) is the best bet. But it not do the emmc. For example the rt809h does the emmc.
This pair of programmers are a good chioce? Thanks!

You can still get PCI (various flavors) parallel port cards.  And you can then load drivers/dlls that trick the willem eprom software into talking to it.  It works, I use it.  It is a hassle however...

Yes, that would be an alternative, i have also a desktop pc with win xp. But in any case the willem can't last forever.... would be nice something  via usb...

The TL866II plus is the current model.

Thanks! There is something to check before buying? Counterfait/clone models that can give problems etc?
I have seen also some programmers with ez-something name. There are differences between this and tl866ii?

According to an Amazon review I noticed a while back, the TL866II Plus has a lower programming voltage (18V compared to 21V) of the TL866A  -  which means some older EPROMS like 2532 or 2732 cannot be programmed with the Plus.

Yes that's correct that's why I'm hanging on to my old CS, which works fine anyway so why spend money. I only have a handful of old EPROMs and no old equipment to maintain. If needed I'd make an adaptor from 28 to 24 pin EPROMs.

Incidentally I run the TL866CS program on XP in a VirtualBox VM on Linux. Works a treat using USB forwarding. So I don't worry about XP going pear shaped, I can resume from an old snapshot.

Uh that's bad. The cs seem out of production, but i've seen it both used or new over ebay
I've read here on eevblog that increasing the write times can do the trick with the 866ii programmer with lower vpp. But it work on the long term?

The mfr claims that any old models are fake, so beware of "new" stock. Do you really need to program 21V EPROMs?

Not needed now, but i have some boards that have that type of eprom (and i have already a dunp).
I've found an used cs. There is a way to recognize a fake?

You can program a lower voltage chip you know, no need to have the exact model, as long as the access time is less or equal. No idea.

RT809H is worth to mention.

I don't think anything truly universal exists, instead you'll have to look for the programmers that support the devices you need, likely collecting a small number of "unversal" programmers.

I've been using the XGecu TL866II Plus the past two years and been pretty happy with it, though it doesn't support everything I'd like, such as page addressed ROMs (like Intel 27C011) or FRAM (like Cypress FM16W08).  To cover these, just this week I received the Willem GQ-4X V4 (GQ-4X4), and so far so good, but unfortunately it doesn't support flash (they have a separate flash programmer).  It's more expensive than the TL866II, but still fairly cheap.

You can also use this program directly from Linux: https://gitlab.com/DavidGriffith/minipro

One option for parallel port programmers is a PCIe or Expresscard parallel port, with pcie (vfio) passthrough to a VM. Works well but is less convenient.
