Usage Guide for TL866 Programmer Adapter for 27C400/800/160/322

[Editor]

Although usage of the Digicool Things EPROM Programmer Adapter has been covered in other posts, and the reading of a Mask ROM and programming of an EPROM is also visually demonstrated in a YouTube video, I thought I’d add a post with a detailed written guide of the steps for successfully programming your EPROM.

will this adapter work for the smaller chips like the 24pin or 28pin commodore or atari 8bit cartridge roms or bios chips?

The Adapter is specifically for the for 27C400 / 27C800 / 27C160 / 27C322 family of Mask ROM pinout 16-bit EPROM's.

It is likely that a 24-pin or 28-pin ROM is already supported by your Programmer.

What are the devices that you want to program, and what Programmer do you have?

i have an atari 8bit computer and commodore 64 with some cartridges and a xgecu t48 programmer

Off topic. I found this description of how to change the Vpp voltage on the TL866-II programmer to support 25 volt eproms.
Previously as a q&d hack I've added a 3v lithium cell in series with the Vpp pin. I now have a working old Dataman S3 for high voltage Vpp parts.

From memory, Commodore 64 Cartridges typically use 27C64 (8KB) or 27C128 (16KB) pinout compatible EPROM's.

The T48 programmer can do these on it's own (no adapter needed).

Not sure about Atari's as I've never owned one. But as you're focussed on 8-bit, you should be fine with this age of computer.

Note the T48 is also capable of 25V Vpp, if your were needing this for some of the older (and smaller) 8-bit wide EPROMs.

Here's the list of what devices the T48 directly supports (35969 devices!):
