itsJoel Posted January 30, 2023 Share Posted January 30, 2023 So a few ago I picked up this neat little thing for 5$. Very good condition but without a ROM pack. Since this model has a slot for it I ordered one of those for the sake of making a more "complete" set. Now, this model also has a microphone holder and input jack. Is there anyone that knows if casio made their own branded microphones for these models as well? If so, I would like to find one! Any insight is appreciated as always!

Chas Posted January 30, 2023 Share Posted January 30, 2023 That's a Casio model I have never seen before! There's some elements of the Casio RAP-1 Rapman in your PT's control layout, and the RAP-1 did actually come with its own microphone (I'm not sure if it had Casio written on it though). Problem is, most of them got separated over time and it's very hard to find a RAP-1 complete with original microphone. Another Casio that came with a microphone is the VA-10 "Voice Arranger". Those are rare and don't come up for sale much, plus similar to the RAP-1, unless you find one still boxed complete with accessories (expensive and collectible), they too are often missing the microphone. You could probably find a cheap generic mic that would work and fit that stand. The mics that come with the cheap and nasty kids keyboards would suffice, and they'll probably be fine as they're just a basic condenser type mic. I bought one of these cheap and awful keyboards for a project, $14.99 including shipping, and it came with the microphone, power adapter and charging cable! It truly was an awful keyboard, and the mic was probably the best part! Quote Link to comment Share on other sites More sharing options...
CYBERYOGI =CO=Windler Posted February 8, 2023 Share Posted February 8, 2023 The PT-380 seems to be a variant of Casio PT-88. The CPU of my PT-88 is "OKI M6521-02, 032002, Japan" (60 pin SMD). What is yours? While the PT-88 is only 2 note polyphonic (by omitted keyboard matrix diodes), PT-380 seems to have 4-note polyphony. Likely this is switched by an additional matrix diode somewhere (or is the CPU software number different?). pinout M6521 The "OKI M6521-xx" CPU (pins count anticlockwise, xx = software number of internal ROM) is a 60 pin SMD variant of the M6387 that (unlike older Casio keyboards) supports a matrix of key lighting LEDs without the need of driver transistors. Each LED is wired from an LY to an LX pin. The pins 51..58 can control the ROM-Pack port. Without a ROM-Pack connected, the key lighting apparently uses demo songs from its internal ROM. Like M6387 it is clocked at 21.725 MHz. The versions of "OKI M6521-xx" ("xx" = software number of internal ROM) differ in demo songs, rhythms and sound set. software number hardware class notes & features 02 PT-88 32 keys, key lighting, 100 sounds, 12 rhythms, 5 drumpads, rom-pack, 4 songs 06 RAP-1 30 sounds, 25 rhythms implemented as songs 10 ML-1 25 sounds, 12 rhythms, 10 songs (need no lit sharp keys) 11 ML-2 like 11 with changed 10 songs This pinout was concluded from the service manual of ML-2 (which uses no ROM-Pack), SK-8 service manual and wiring of the PT-88 PCB. pin name purpose 1 LY1 led matrix out 2 LY2 led matrix out 3 LY3 led matrix out 4 LY4 led matrix out 5 LY5 led matrix out 6 LY6 led matrix out 7 LY7 led matrix out 8 LVDD1 led supply voltage +5V 9 LGND2 led ground 10 LX0 supply voltage +5V 11 LX1 led matrix out 12 LX2 led matrix out 13 LX3 led matrix out 14 LX4 led matrix out | NC 15 LX5 led matrix out | NC 16 LX6 led matrix out | NC 17 LX7 led matrix out | NC 18 LVDD2 led supply voltage +5V 19 GND2 ground 20 COSI crystal in | clock in (21.725 MHz) 21 COSO crystal out 22 VDD supply voltage +5V 23 GND1 ground 24 TEST1 (wired to GND) | ? 25 TEST2 (wired to GND) | ? 26 TEST3 (wired to GND) | ? 27 /RESET reset 28 AVDD analogue supply voltage +5V 29 OUT sound out 30 AGND analogue ground 31 KI0 key matrix in 32 KI1 key matrix in 33 KI2 key matrix in 34 KI3 key matrix in 35 KI4 key matrix in 36 KI5 key matrix in 37 KI6 key matrix in 38 KI7 key matrix in 39 KO0 key matrix out 40 KO1 key matrix out 41 KO2 key matrix out 42 KO3 key matrix out 43 KO4 key matrix out 44 KO5 key matrix out 45 KO6 key matrix out 46 KO7 key matrix out 47 KO8 key matrix out | NC 48 KO9 key matrix out | NC 49 KO10 key matrix out | NC 50 KO11 key matrix out | NC 51 D4 rom pack bus 52 D3 rom pack bus 53 D2 rom pack bus 54 D1 rom pack bus 55 OP rom pack /adress data 56 ø2 rom pack clock2 57 ø1 rom pack clock1 58 CE rom pack enable 59 LGND1 led ground 60 LY0 led matrix out Quote Link to comment Share on other sites More sharing options...
