I am now offering 8B PCB set to early adopters a special price of $275 plus shipping. Though my prototype system has been brought up and basically checked, it hasn’t been fully checked with a full complement of memory and PROM cards. Also I/O port testing has been minimal. There could be additional issues beyond those already documented in my blog that will require rework. Once checkout is considered fully complete, the price of a board set (minus PROM card) will rise.
The introductory set contains one each of the following PCBs. Extra SRAM cards are available now at $50 each. This set does not include the PROM card, which is still under development. Estimated time before PROM card will be available is 3 months, give or take 2 or 3 months.
1100 CPU
1101 DBB
1102 INPUT
1104 Front panel
1106 memory expansion
1107 4k SRAM (1)
1108 8B Backplane

I’m not sure when chassis sheet metal will be available, as I’m looking for bargain on a used Box and Pan Brake, so I can fabricate them at substantial savings over contractors prices. Note that not just any brake will do, it has to handle a minimum of 2′ of 16 gauge stock with at least a 4″ depth. for now, you can fabricate your own temporary chassis or use an off the shelf Bud AC-413. The only problem with the Bud chassis is that the original chassis were 3.5″ high and the AC-413 is only 3″ high.
I hav updated BOM for SCELBI 8B if anyone interested.
