You can literally see the ladder array in the inside pics below.

From the listing:

"I have only seen this quality of construction on military equipment. I slid the sides off to get the pictures. The four Allan Bradly pots that are geared together for frequency selection give a 24db per octave cutoff slope. This could be the finest analog filter of its kind. Selectable Low Pass or High Pass. Low pass is DC coupled for best fidelity. Frequency range 20Hz to 2 Mhz . COMPLETE bench test. This unit is 100%... Complete specs can be found here."

Interesting accessory.

"Original vintage Yamaha ADP1 cartridge adapter. The ADP1 allows the original DX-7 cartridges to be used in your DX-7 II cartridge port. Works perfectly."

This is the first post to feature Radiusz. Note the listing is for the card only, not the Microwave.

Details from the listing:

Custom-built Multibank RAM Cartridge with 16 banks for the storage of sound patches and performances. So it's essentially 16 (or 8 or 4*) cards in 1 !

Compatible with Waldorf Microwave Mk1, and all synths etc. that use the Bee-Card type cards. (01/W, Wavestation Series, M and T Series, DS8, 707, A1-A2-A3 FX processors....)

NOTE 1: Korg MCR-03 is in fact identical, it's only a name re-brand by Korg after adopting the Bee-card cartridge format, for use in their equipment.

NOTE 2: Can be configured as either 16 banks x 32 kB, 8 banks x 64 kB, or 4 x 128 kB card. 16 x 32 kB is most common, but please specify the required format upon ordering. Thank you!

Bank selection rotary switch, back-up battery with a life span of 40+ years (Yes, those modern memory chips really are a LOT more energy efficiƫnt than those old ones! ;-) "
