FM-PAC repair

My FMPAC have not been not worked on my PV-16 well. In such a case, capacitor causes error sometimes.

I have tryed to replace capacitors on my FMPAC(Panasoft version).

Check parts

I found FMPAC electric circuit this cite and checked parts first.

FMPAC SW-M004 回路図 | 電子機器 Junker – teacup.ブログ“AutoPage”

List of electrolytic capacitors in FMPAC(Pana)
10uF16V * 4
47uF16V * 2
1uF50V * 1
1uF50V(non-polarized) * 1 1000uF6.3V * 2

C17 is non-polarized and I changed ceramic one from electrolytic.



I leaved Battery removed because I don’t use FMPAC as PAC to save data for a while.
I inserted FMPAC into KB-7(dock), not PV-16(main unit) and works well with 64k extend ram cartridge.

My opinion towards retro hobby computers

I want to enjoy playing HOBBY COMPUTING!

Remember 80’s… There were many hobby computers.

There are not so many joyful computers nowadays.
Almost of all computers are compelling graphics or
processing speed for business use…

Are you enjoying with such computers?

I think, we have the rights to enjoy computers.

We, fans of retro computers do as fun of vintage cars.

They don’t complain about speed(slow) or designs that is
not so smart(old school) but love such a elements that
have already vanished.

Only one thing that is same between old days and now is
“both of them can reach where you want to go”.

I just enjoy old hobby computer.
