Visual 1083 Commuter: Part 2 (Quick Update)
16A quick update on my plans:
[1] PSU refurbish:
Converted from 115VAC to 230VAC by moving one wire, and am replacing the RIFA X-class safety capacitors (0.1µF and two 0.01µF).
[2] Replacement fan:
The original fan is 115VAC so have ordered a new 80mm square, 230VAC fan - no idea what the other fan specs are, or even its model ... although watching the video, there may have been a sticker that has come off ... ?
[3] 8087 maths co-processor:
Will install a socket for eventual 8087 installation.
[4] Colour LCD install:
Big thanks to @ronanderson1839 for his copious notes, I'm planning to run cable from the external RGBI DIN socket to screen, and power from within the machine via the empty synch/asynch port panel.
Install a 7-pin DIN socket on the display panel so the cables can be removed when closing it up - five pins for the RGBI and two for the power (5V and 12V?).
The 8" Eyoyoyoyoyo screen I have at the moment is too large, but they also do a 5" model with HDMI & VGA inputs - couple this with an RGB2HDMI converter and ... add some hot-snot & duct tape ... job done?
[5] External ISA expansion:
I want to design an external ISA expansion board ... if none already existing? ... to connect via the DC-62 expansion port to allow CF storage.
It was apparently designed for use with the IBM Model 5161 Expansion Chassis ... interface specifications?
[6] Replace 8088:
I have some V20s so might replace the 8088 for a little increase in performance.
