GGLABS E2R16v2.1 PCB - TL866 27C400 27C800 27C160 27C322 Programming Adapter

Description

GGLABS E2R16v2.1 Programmer Adapter PCB for TL866.
Allows to read/write 27C400,27C800,27C160 and 27C322 series UV EPROMs (ROM compatible pinout suitable for many vintage computer, consoles and arcade machines).
Version 2.1 with new form factor to improve mechanical fit and additional PNP to address compatibility issues with C322 mode on some TL866.
Listing is for the bare PCB only. No Components are included in this listing.
Hate soldering SMD components? Please see
this listing
for a partially assembled board (need only four easy to solder PTH components)
The assembled E2R16v2 and the TL866 in the pictures are only for demonstration and are not included in the sale.
To use the adapter to read or write 27C400,C800,C160 and C322 EPROMs select 27c4096 and de-select "check ID".
Set the DIP switch to the correct configuration, then then read or write a 512K block.
Repeat for every 512K block that need to be read/programmed.
List of components needed to complete a universal adapter:
2x 20 pin 100mil (2.54mm) pitch male headers
1x 42 or 48 pin socket
2x 0.1uF 16V X7R 1206 capacitors (C1,C2)
9x 10k ohm 1206 resistors (R3,R4,R5,R6,R8,R9,R10,R11,R12)
1x 2.2k ohm 1206 resistors (R7)
3x SOT-23 MMBT3906 PNP transistors (Q1,Q2,Q4)
1x SOT-23 BSS138 N-channel mosfets (Q3)
1x 4-position DIP switch
1x SOD123 1N4148 diode
Please note that R1 and R2 are not needed in this configuration.
If you are not interested in the 27C322 the list of component can be simplified to:
2x 20 pin 100mil (2.54mm) pitch male headers
1x 42 or 48 pin socket
2x 0ohm 1206 resistors (R1,R2)
2x 10k ohm 1206 resistors (R8,R9)
1x 2-position DIP switch
Designed in USA.
