Company where I work does not use PayPal because of bad experiences from the past.

I can offer MM5311 (max 10 pcs) or MM5402 (15 pcs).

Either use digital circuit with non-multiplexed outputs (e.g 5316) where you need convert 7-segment code to BCD or use circuit with BCD multiplexed outputs. Demultiplex the outputs into 4-bit latches. The decoders 141 follows the latches and drives the nixie. Let me know if you need schematics.

Does the SATA expansion card have a BIOS or is it just a dummy SATA card?

why not use 80C187 ?

8242 was dedicated kbd controller. Beside that exists VT82C42 and VT82C416 often available on eBay from China. Datasheet for VT82C42 is known, while docs for VT82C416 are unknown.

It exist vintage dedicated digital clock circuits from National Semiconductor like MM5316, MM5314 and others. Still available on eBay.

It seems that Circuit Studio is a dead Altium project. There is Circuit Maker, a new Altium project. This is probably a limited version of Altium 365. Circuit Maker should run in the cloud. I tested it briefly. Too many components, symbols, footprints are missing from the “extensive” library :D. The...
