content: How much is postage to California? That price is for a bare PCB, right?Schematic?What's the rightmost socket? More RAM?Sigh. I do want an 8051 PCB, partially to use up the chips I've collected. But those are mostly DIPs. Designing for and Marketing to hobbyists is ... frustrating.

content: Quote from: westfw on December 30, 2016, 05:18:17 amI have to check the UPS price list.I believe it would be something like 20 euro.Quote from: westfw on December 30, 2016, 05:18:17 amIt's for the board you can see in the picture, already mounted and tested (except the ISA8 but)The UV-Eprom is missing in the photo, but it will be provided, empty, or burned with BASIC-51Quote from: westfw on December 30, 2016, 05:18:17 amI might have them, somewhere. You can also reverse the schematic, it's a very simple circuit.Anyway, I have to check for it.Quote from: westfw on December 30, 2016, 05:18:17 amyep, it was the same here with a 68000 board I have recently designedI say a very frustrating and expensive experience, the first and the last time I do something like thatIt also took a lot of time to get all the chips DIP packagedMy next stop comes with fpga. Definitively!

content: I might also have for sale a bigger boardIt's all-dip-packaged chips.CPU, and glue logic chips, they all come in dip package.and it comes with8051, DIP package, clocked @ 11MhzROM, 32Kbyte, currently it contains intel basic-51RAM, 32KbyteEEPROM sockets, 3 sockets, 8Kbyte each, sorry they are emptyTTL-RS232 and cableit's 160x110mm board, 2 layerswith schematic and a backplane.But I will ask 60 euro for it. Plus postage.I have to take some pictures.Currently I don't have a camera with me.

At the moment the server is offline since with my friends we are physically moving the "bunker" (1) and the server (a cluster of 2 mac-mini/PPC) ten meters underground(1) funny name, it's a joke, but look at the URL's name, it's really "www dot downthebunkerdot xyz", and it will be really hosted in a true underground mini-bunker
