RESORC needs some fixing before the RESOURCES command will generate good output for the ID01 and VM01 devices. The first fix is to add ID and VM to the list of devices that use the A0-Bn convention. This table is located from locations 13126 to 13136 with a terminating zero in location 13137. Location 13136 is unfortunately the only free entry in the table: 13126/0424 /DT 13127/1524 /MT 13130/1424 /LT 13131/2404 /TD 13132/0323 /CS 13133/2213 /RK 13134/2206 /RF 13135/2230 /RX 13136/0000 /patch space 13137/0000 /list terminator So, it will be necessary to replace the entry for a device unlikely to ever be attached to the SBC6120 (say, "CS"). The other fix is to inform RESORC that device types ID01 and VM01 exist, and their sizes: Device 43 goes at location 02214: 2615 / DEVICE VM01 6061 5300 / size (-1344) 0000 / no special routine Device 44 goes at location 02220: 1104 / DEVICE ID01 6061 0001 / size (-4095) 0000 / no special routine These locations should be zeroes before the patch is applied. So, here's the patch: .GET SYS:RESORC .ODT 13132/0323 1104 13136/0000 2615 2214/0000 2615 2215/0000 6061 2216/0000 5300 2217/0000 0000 2220/0000 1104 2221/0000 6061 2222/0000 0001 2223/0000 0000 ^C .SAVE SYS:RESORC VRS
