XT-CF-RA
About the XT-CF-RA PCB
XT-CF-RA is an open source PCB design by monotech, published on GitHub under the GPL-3.0 license. It is a 2-layer board measuring 100.4 × 96 mm, with 29 components from 22 distinct parts.
Other key parts include the 74LS04, 74LS32, 74LS688, 28C256 and 74LS33. By type, the board carries 8 capacitors, 6 ICs, 5 switches, 5 resistors, 2 connectors and 1 jumper.
From the project
Rear-accessible XT-CF Bootable 8-bit ISA CompactFlash - no bracket machining required
Monotech XT-CF Rev1.0 ReadMe ----------------------------
8-bit ISA CompactFlash interface + Boot ROM (two separate functions that can be used individually).
Documentation for the switches can be found on the rear silkscreen.
Credit: ------- Design uses schematic from Sergey Kiselev, with a few small changes to switches, 32K ROM support, and PCB from scratch to suit my brackets.\ www.malinov.com/Home/sergeys-projects/xt-cf-lite
